AMD Catalyst 12.11 Beta 7 - CoD Black Ops Edition

Subject: Graphics Cards | November 13, 2012 - 06:02 PM |

When AMD promised to move off of a monthly release schedule for their Catalyst Control Center and drivers, we didn't think that would mean we would see multiple releases from them every month.  If you count the beta versions then that is exactly what is happening, today the release of the 12.11 Beta 7 driver is available on their beta driver page.   We have listed the improvements offered by previous versions of the 12.11 Beta driver and they are quite impressive, this particular version adds one more to the list of improvements.  Players of Call of Duty: Black Ops 2 should be grabbing this driver as the improvement is specific to the CrossFire compatibility of that game.  AMD does not specify a percentage increase but they do state you will see much better performance on CrossFire systems, especially if you are playing at 2560 x 1600 and above ... which you really should be if you are running a CrossFire system.  It has all the previous benefits as well, so if you've been holding off on upgrading your graphics driver, this might be a good excuse to do so.

AMD Launches Dual Tahiti FirePro S10000 Graphics Card

Subject: Graphics Cards | November 13, 2012 - 04:15 PM |
Tagged: tahiti, HPC, gpgpu, firepro s10000, firepro

On Monday, AMD launched its latest graphics card aimed at the server and workstation market. Called the AMD FirePro S10000 (for clarity, that’s FirePro S10,000), it is a dual GPU Tahiti graphics card that offers up some impressive performance numbers.

No, unfortunately, this is not the (at this point) mythical dual-7970 AMD HD 7990 graphics card. Rather, the FirePro S10,000 is essentially two Radeon 7950 GPUs on a single PCB along with 6 GB of GDDR5 memory. Specifications on the card include 3,584 stream processors, a GPU clock speed of 825 MHz, and 6 GB GDDR5 with a total of 480 GB/s of memory bandwidth. That is 1,792 stream processors and 3 GB of memory per GPU. Interestingly, this is a dual slot card with an active cooler. At 375W, a passive cooler is just not possible in a form factor necessary to fit into a server rack. Therefore, AMD has equipped the FirePro S10,000 GPGPU card with a triple fan cooler reminiscant of the setup PowerColor uses on its custom (2x7970) Devil 13, but not as large. The FirePro card has three red fans (shrouded by a black cover) over a heatpipe and aluminum fin heatsink. The card does include display outputs for workstation uses including one DVI and four mini DisplayPort ports.

AMD is claiming 1.48 TFLOPS in double precision work and 5.91 TFLOPS in single precision workloads. Those are impressive numbers, and the card even manages to beat NVIDIA’s new Tesla K20X with big Kepler GK110 and the company’s dual GPU GK104 Tesla K10 by notable margins. Additionally, the new FirePro S10000 manages to beat its FirePro 9000 predecessor handily. The S9000 in comparison is rated at 0.806 TFLOPS for double precision calculations and 3.23 TFLOPS on single precision work. The S9000 is a single GPU card equivalent to the Radeon 7950 on the consumer side of things with 1,792 shader cores. AMD has essentially taken two S9000 cards and put them on a single PCB, and managed to get almost twice the potential performance without needing twice the power.

Efficiency and calculations per watt were numbers that AMD did not dive too much into, but the company did share that the new FirePro S10000 achieves 3.94 GLOPS/W. AMD compares this to NVIDIA’s dual GPU (Fermi-based) Tesla M2090 at 2.96 GFLOPS/W. Unfortunately, NVIDIA has not shared a single GPU GFLOPS/W rating on its new K20X cards.

  AMD S10000 AMD S9000 NVIDIA K20X NVIDIA K10
Double Precision 1.48 TF 0.806 TF 1.31 TF 0.19 TF
Single Precision 5.91 TF 3.23 TF 3.95 TF 4.58 TF
Architecture Tahiti (x2) Tahiti (x1) GK110 GK104 (x2)
TDP 375W 225W 235W 225W
Memory Bandwidth 480 GB/s 264 GB/s 250 GB/s 320 GB/s
Memory Capacity 6 GB 6 GB 6 GB 8 GB
Stream Processors 3,584 1,792 2,688 3,070
Core clock speed 825 MHz 900 MHz 732 MHz 745 M
MSRP $3,599 $2,499 $3,199 ~$2500

Other features of the AMD FirePro S10000 include support for OpenCL, Microsoft RemoteFX, Direct GPU pass-through, and (shared) virtualized graphics. AMD envisions businesses using these FirePro cards to provide GPU hardware acceleration for virtualized desktops and thin clients. With Xen Server, multiple users are able to tap into the hardware acceleration offered by the FirePro S10000 to speed up desktop and speed up programs that support it.

Operating systems in particular have begun tapping into GPU acceleration to speed up the user interface and run things like the Aero desktop in Windows 7. High end software for workstations also have a high GPU acceleration adoption rate, so there are benefits to be had, and AMD is continuing to offer it with its latest FirePro card.

AMD FirePro Market Position_Aimed at Server Graphics.png

AMD is offering up a card that can be used for a mix of compute or graphics output, making them an interesting choice for workstations. The FirePro S10000’s major fault lies with a 375W TDP, and while the peak performance is respectable it is going to use more power while provided that compute muscle.

The cards are available now with an MSRP of $3,599. It is neat to finally see AMD come out with a dual GPU card with Tahiti chips, and it will be interesting to see what kind of design wins the company is able to get for its beastly FirePro S10000.

AMD's new FirePro S10000 sports two GPUs

Tagged: amd, Intel, firepro, firepro s10000, HPC, Xeon Phi, 3120A, 5110P, Knight's Corner

AMD's new Tahiti based FirePro S10000 sports a little more than just a GPU upgrade it sports two GPU updates as this is a dual GPU card.  According to The Register it should run about $3,600 and need 375W to perform, numbers which make it a more efficient card than the S9000 even though it needs significantly more cash and power to run.  It is a 2 slot card, a necessity in the server and workstation world and while it does not support CrossFire it does support EyeFinity with its DVI port and four Mini DisplayPorts.

elreg_amd_firepro_s10000.jpg

The Register also got some news about Xeon Phi, Intel's answer to the HPC cards on offer from AMD and Intel.  Knights Corner is the evolution of Larrabee into an actual product, in this case two 62 core cards though not all of the cores are active. The passively cooled 5110P has 60 cores running at 1.053GHz, while the 3120A has 57 cores clocked slightly higher at 1.1GHz and sports a fan.  Both cards produce just over a teraflop of double precision floating point math, compared to the 1.48 teraflops offered by AMD's S10000 or the 1.3 offered by the Tesla K20x. Check out more on these coprocessors at The Register.

elreg_intel_xeon_phi_die_shot.jpg

"With the FirePro S10000, not only is the GPU geared down to 825MHz, but the memory is similarly downshifted to 5GHz. The memory interface is 384-bit wide on each GPU, with two blocks of GDDR5 memory yielding a total of 6GB. (This could be a little skinny on the memory for some HPC workloads, given that the S9000 card has 6GB of memory for one Tahiti GPU.) Each GPU can access 240GB/sec of memory bandwidth linking to each 3GB chunk of GDDR5 memory.

Because the card is double-stuffed, it can deliver a very impressive 5.91 teraflops SP and 1.48 teraflops DP in peak floating point oomph."

Woah! AMD overclocked the Matrix

Subject: Graphics Cards | October 22, 2012 - 03:47 PM |
Tagged: asus, Matrix HD 7970 Platinum, amd, factory overclocked

The ASUS Matrix HD 7970 Platinum is an impressive card, physically as well as the performance it offers.  It is a triple slot card measuring 11.25" long and 5.5" deep, so you might want to measure the space you have before thinking of purchasing one, it also weighs in at over 3lbs (1.4kg) which you should also keep in mind.  While it is factory overclocked to 1050MHz on the GPU and memory of 6.6GHz, if you plan on leaving those numbers untouched you are missing out on the real reason to pick up this particular HD 7970.  When [H]ard|OCP put the 20-phase Super Alloy Power technology and chokes to the test they hit 1310MHz on the GPU and pushed the memory to 7GHz, far beyond what any other HD 7970 they've reviewed could manage.  That overclock was definitely noticeable when they benchmarked the card, which helped it win a Gold Award as the best HD 7970 they've seen ... even if it is hard to find for purchase.

H_7970matrix.jpg

"ASUS is launching its highest-end ASUS MATRIX HD 7970 Platinum video card today, poised to give you the best experience possible out of a Radeon HD 7970. This highly customized video card is geared directly towards the hardware enthusiast. Come see the highest overclock we've ever achieved on a 7970 GHz Edition based video card."

AMD Offers Impressive Never Settle Bundle with Radeon GPUs

AMD has a couple of surprises for gamers today, both using the "Never Settle" branding.  Later this morning you will see an article that looks at a new driver revision - 12.11 beta - that will be published this week (it maybe online already).  Promising performance increases is 20% and more, it should be an interesting discussion.

Another big push for AMD going into the holiday season will be the Never Settle game bundle; a collection of games included with a graphics card purchase unlike you have ever seen before.  And we aren't talking about scrub games here, with the HD 7900 series of cards you'll see Far Cry 3, Hitman: Absolution, Sleeping Dogs and Medal of Honor Warfighter.

02.jpg

Starting today, if you buy an AMD Radeon HD 7900 series of graphics cards, including the HD 7990, HD 7970 and HD 7950, you will get three full games absolutely free!  Far Cry 3, Hitman: Absolution and Sleeping Dogs to be exact.  Also, you will get a 20% discount on a copy of the new Medal of Honor: Warfighter.  And because I already asked, AMD assures us that this is the ONLY discount on Medal of Honor that will be available this year.

03.jpg

Buyers on tighter budgets aren't going to be left out and if you pick up an HD 7800 series or an HD 7770 GHz Edition (not a 7750), you'll get a free copy of Far Cry 3 as well as the 20% off offer on Medal of Honor. 

And just to mix things up, if you buy a PAIR of Radeon HD 7800s or a pair of HD 7770 GHz Editions AMD will add in a free copy of Hitman.

01.jpg

I realize that not every gamer is interested in every game that is released, but the value of the Never Settle bundle is really unmatched in anything I have seen before.  Valued at $170, the package that you can get by purchasing a Radeon HD 7950 3GB for $299 in theory brings the total out of pocket price of the GPU to $129!! 

As I have mentioned previously, bundles are not a cure-all for performance issues, but they can definitely swing a buyer's decision when the other factors are close.  I think AMD will have a HUGE advantage going into the holiday buying season even though NVIDIA has the Assassin's Creed 3 bundle (with the GTX 650 Ti) and the Borderlands 2 bundle (with the GTX 660 Ti and above). 

See what happens when you have healthy competition in the market?  Gamer's always come out ahead!

We are at the first AMD ExtravaLANza today getting some hands on time with some cool new hardware as well as new games like Far Cry 3, Tomb Raider and Hitman: Absolution.  We attended a session with the Hitman developer IO Interactive where some interesting information about the DX11 features.  I recorded a video of the presentation for those interested in seeing it in its entirety.

The brand new Glacier2 engine has some impressive new features including:

  1. DX11 hardware tessellation on character models
  2. A global illumination engine using light propagation volumes
  3. AA options including FXAA and MSAA 2x-8x
  4. Eyefinity and HD3D

There is more, but you can hear it all in the video above.  IO Interactive wanted to assure PC gamers that they are developing the game to be a first class PC title with higher quality imaging, controls and texture detail; this doesn't look to be a standard console port.

Zotac Rumored To Be Preparing Three GTX 650 Ti Graphics Cards

Subject: Graphics Cards | October 7, 2012 - 10:37 PM |
Tagged: nvidia, kepler, gtx 650ti, gpu, gk106-220

The NVIDIA GeForce GTX 650 Ti is rumored to launch soon, and so far specifications have leaked on the reference design as well as two custom cards from ASUS and Galaxy. Zotac is the latest manufacturer to have its GTX 650 Ti lineup leaked, and the company is bringing as many as three graphics cards to the GK106-220 Kepler family. In all, Zotac is rumored to be launching one 1GB GTX 650 Ti and two 2GB GPUs – all with vared levels of factory overclocks. Video outputs on all three cards include two DVI and two HDMI connectors.

Zotac GTX 650 Ti 2GB AMP Editon.jpg

The Zotac GTX 650 Ti 1GB stays close to the reference design, but bumps up the GPU core clockspeed to 941 MHz. It also includes 1 GB of GDDR5 memory on a 128-bit interface clocked at 1350 MHz (5400 MHz effective), which matches the reference design. The price of this card is said to be $160, and features a custom cooler from Zotac that is similar (but smaller than) to the cooler used on the company's GTX 660 Ti GPU wich we recently reviewed.

The Zotac GTX 650 Ti 2GB is, as the name suggests, a GTX 650 Ti graphics card with 2GB of GDDR5 memory. It features Zotac's custom cooler, and a single PCI-E 6-pin power connector. The GPU clockspeed is 941 MHz and the memory clockspeed is 1350 MHz. The extra 1GB of graphics memory is nice, but it is still on a 128-bit interface so don't expect too much of a performance boost. MSRP of this card is rumored to be $180.

Finally, the GTX 650 Ti 2GB AMP! Edition is Zotac's highest-end GTX 650 Ti graphics card. It comes with the GK106-220 Kepler GPU and 2GB of GDDR5 memory on a 128-bit bus. Powered by a single 6-pin PEG connector, the factory overclocked graphics card is clocked at 1033 MHz for the GPU and 1550 MHz (6200 MHz effective) for the memory.The Zotac GTX 650 Ti AMP! Edition comes with the company's custom cooler and is the first card to feature factory overclocked memory. The rumored price of this card is $190. Unfortunately, that puts it fairly close to the price of a reference GTX 660, which may make this card a hard sell. The factory overclocks are impressive, but saving up the extra $30 needed to get a GTX 660 is likely a better idea because it will still offer up better performance thanks to the additional CUDA cores and wider memory bus.

The following chart compares the three Zotac cards to the leaked reference specifications.

  Reference Specifications Zotac GTX 650 Ti 1GB Zotac GTX 650 Ti 2GB Zotac GTX 650 Ti 2GB AMP! Edition
CPU Clockspeed 925 MHz 941 MHz 941 MHz 1033 MHz
Memory Clockspeed 1350 MHz 1350 MHz 1350 MHz 1550 MHz
GDDR5 Amount 1 GB 1 GB 2 GB 2 GB
Price ~$140 $160 $180 $190

Comparison of several GTX 650 Ti graphics cards versus the rumored reference specifications.

Further, this chart compares the leaked specifications of the top end cards from each manufacturer (at least, the ones we know of so far) to the highest-end Zotac GPU: the 2GB AMP! Edition.

  Reference Specifications ASUS GTX 650 Ti TOP Galaxy GTX 650 Ti GC 1GB Gigabyte GTX 650 Ti OC Zotac GTX 650 Ti 2GB AMP! Edition POV GTX 650 Ti 1GB Ultra Charged
CPU Clockspeed 925 MHz 1033 MHz 966 MHz 1032 MHz 1033 MHz 1058 MHz
Memory Clockspeed 1350 MHz 1350 MHz 1350 MHz 1350 MHz 1550 MHz 1350 MHz

Price ~$140 €206 (~$267?) $150 €169 $190 unkown

Inno3D is also rumored to have a GTX 650 Ti graphics card coming out, but we don't know clockspeeds or price on it. Only that it has two DVI and one HDMI connector, a single PEG power connector, and a custom cooler.

Overall, the Zotac card measures up well, with pricing being the only major disadvantage. The 2GB of memory, factory overclocks, and two HDMI ports are welcome additions, however. Interestingly, the Zotac card is not the highest clocked graphics card overall, but it is the only one that features overclocked memory. It is unclear to me why manufactuers of NVIDIA cards are so hesitant to push the memory clockspeeds (or if they are even allowed to), but Zotac seems to prove that it is possible to do so. 

Also worth pointing out is the rumored pricing, as some of these custom graphics cards are pushing $200 (especially the ASUS card when coverted to USD... I'm sure that has to be in error...), and reference GTX 660 with the full GK106 Kepler core are only $230. It will be interesting to see if these rumored prices turn out to be true, and how well Zotac's factory overclocked 650 Ti models sell.

Gigabyte's Windforce cooler has become popular thanks to its efficient performance and low noise, which makes it perfect for a card like the GTX 660 which you would expect to find in a small enclosure.  Gigabyte gave a little more power to this non-Ti GTX 660 however, with a base clock of  1033MHz, boosting to 1098MHz and GDDR5 at 6GHz which Guru of 3D managed to increase when they tried overclocking the card and ended up with many benchmarks equalling or surpassing a GTX 660 Ti.  At $230 the Gigabyte GeForce GTX 660 Windforce OC is not a bad choice for a system that needs to be quiet and won't be used to play the newest games at high settings,

PowerColor shows off new (cheaper) HD 7990 graphics card with lower clocks than Devil 13

Subject: Graphics Cards | October 5, 2012 - 06:40 PM |
Tagged: powercolor, gpu, dual gpu, amd, 7990

Towards the end of August, a new dual GPU graphics card from PowerColor was fully detailed. The dual GPU Devil 13 graphics card combined two AMD Radeon HD 7970 GPUs onto a single PCB with factory overclocks and a custom cooler. The 6GB (3GB per GPU) HD 7990 6GB Devil 13 is an awesome card, but comes with a hefty $999 price tag.

This month, PowerColor has taken the wraps off of a (slightly) cheaper 7990 graphics card that is not clocked as high but uses a similar custom cooler as the Devil 13. It will allegedly be priced at around $900 USD.

PowerColor Radeon HD 7990.jpeg

The new PowerColor HD7990 (sans Devil 13 branding) features two HD7970 Graphics Core Next (GCN) based GPUs  clocked at 900 MHz by default or 925 MHz when using the factory overclocked BIOS. (You can switch between the two modes by using the Dual BIOS switch.) As a point of comparison, standard Radeon 7970s have a reference clockspeed of 925 MHz, and PowerColor’s own HD 7990 Devil 13 is clocked at either 925 MHz or 1 GHz depending on BIOS switch position. PowerColor is likely binning 7970 GPUs that don’t quite make the cut as Devil 13 models for this new dual gpu 7990 graphics card with lower clockspeeds.

Fortunately, the memory clockspeed has not been downclocked on the new HD 7990. Each GPU has 3GB of GDDR5 memory on a 384-bit bus, and the memory is clocked at 1375 MHz.

Also good news is that the standard PowerColor 7990 appears to use the same custom cooler as the Devil 13 – but with an all-black design rather than the red and black color scheme. That includes a triple slot design, numerous heatpipes and fins, and two 92mm fans on either side of an 80mm fan.

The graphics card measures 315mm x 140mm x 60mm and features two DVI, one HDMI, and two min-DisplayPort video outputs. It has the same 850W minimum system power requirement as the Devil 13, and is powered by three 8 pin PCI-E power connectors in addition to power from the PCI-E 3.0 x16 slot.

Although an interesting card that is sure to attract enthusiasts, it lends credence to the idea that AMD is not going to release its own reference HD 7990 after all. At this point, so long as your case and motherboard permit, it would likely best to go for two individual ~$400 Radeon 7970 GHz Edition cards in a CrossFire configuration. PowerColor does seem to have you covered if that’s not an option for you though there is no word on exactly when this graphics card will be available – or what the final pricing will be.

Gigabyte Launches Three New Factory Overclocked Kepler GPUs

Subject: Graphics Cards | October 4, 2012 - 04:42 PM |
Tagged: nvidia, kepler, gtx 680, gtx 670, gtx 660 Ti, gigabyte, factory overclocked

Gigabyte is launching three new factory overclocked graphics cards featuring a Kepler GPU, custom PCB, and custom cooler. The factory overclocks are notable, but will cost you. Specifically, the company is producing versions of the GTX 660 Ti, GTX 670, and GTX 680.

GTX 680.jpg

The Gigabyte GV-N680OC-4GD takes the GTX 680 GPU, places it on a custom PCB, and pairs it with 4GB of GDDR5 memory. It features two 6-pin PCI-E power connectors, and Gigabyte’s Windforce X3 450W custom cooler using a triangular fin design that allegedly increases cooling potential. While the GDDR5 memory clockspeeds have not been increased over the reference clocks, the GPU core and boost clockspeeds have been pushed to 1071 MHz and 1137 MHz respectively. The following chart shows the differences in clockspeed and memory over the reference design.

  Reference GTX 680 Gigabyte N680OC-4GD
GPU Core 1006 MHz 1071 MHz
GPU Boost 1058 MHz 1137 MHz
GDDR5 Amount 2 GB 4 GB
GDDR5 Speed 6 Gbps 6 Gbps
Price $500 $800 (rumored)

 

The GTX 680 is not the only card to get a custom makeover by Gigabyte, however. The GV-N670OC-4GD is a custom GTX 670. With this card, Gigabyte has set the base clockspeed at 980 MHz – the boost clockspeed of reference cards – and the boost clockspeed at 1058 MHz. Gigabyte has also doubled down on the GDDR5 memory by packing 4GB onto the custom PCB. The memory clockspeed remains the same 6 Gbps as reference cards, however.

GTX 670.jpg

This card uses the same Windforce X3 cooler as the cust GTX 680, and as a result has a triple slot design that looks identical to the N680OC-4GD. If you look just above the PCI-E connector though, you can see tell them apart by the product name.

  Reference GTX 670 Gigabyte N670OC-4GD
GPU Core 915 MHz 980 MHz
GPU Boost 980 MHz 1058 MHz
GDDR5 Amount 2 GB 4 GB
GDDR5 Speed 6 Gbps 6 Gbps
Price $400 $550 (rumored)

 

Finally, we have the GV-N66TOC-3GD which overclocks the GTX 660 Ti GPU to the max. Factory clockspeeds are set at 1032 MHz base and 1111 MHz boost. Memory also sees a small bump from 2GB reference to 3GB. On the other hand, the memory is not overclocked and remains at the reference 6 Gbps clockspeed. This card also has a triple fan Windforce cooler, however this version is not the triple slot design found on the GTX 670 and GTX 680s SKUs – only dual slot.

  Reference GTX 660 Ti Gigabyte N66TOC-3GD
GPU Core 915 MHz 1032 MHz
GPU Boost 980 MHz 1111 MHz
GDDR5 Amount 2 GB 3 GB
GDDR5 Speed 6 Gbps 6 Gbps
Price $300 $415 (rumored)

 

All three of the Gigabyte GPUs feature two DVI, one full-size HDMI, and one full-size DisplayPort connector for video outputs. 

All three factory overclocked graphics cards feature respectable GPU overclocks, and it appears that Gigabyte has provided ample cooling for each GPU. The triple slot, triple fan version on the N670OC-4GD and N680OC-4GD in particular seem to offer headroom above even what Gigabyte has clocked these out of the box. Curiously though, Gigabyte is continuing the trend of not touching the memory clockspeed of Kepler cards. It may be that the RAM chips are already at their max on the reference design, or there could be some behind the scenes talk with NVIDIA not waning Add In Board partners to touch the memory Unfortunately, all I have at this point is speculation, but it is a rather curious omission on such high end cards. That point becomes clearer when price is taken into consideration. Videocardz claims to have the pricing information for the three video cards, and the custom cards are going to cost you a large premium over reference cards. The rumored prices can be found in the charts above compared against the reference pricing, but the basic run down is that the GV-N66TOC-3GD will cost $415, the GV-N670OC-4GD will cost $550, and the GV-N680OC-4GD will cost (an astounding) $800.

I’m hoping that the rumored prices are in error and will be adjusted once the cards are available. These are neat cards that look to have plenty of cooling, but I’m still trying to figure out just what these cards have to offer to justify the huge jump over reference pricing. And, no, the superfluous gold plated HDMI connectors do not count. [For example, the 4GB Galaxy GTX 670 we recently reviewed was only $70 over reference while the Gigabyte card is rumored to be $150!]

AMD Radeon HD 7870 GHz Edition Revisited

Subject: Graphics Cards | September 25, 2012 - 02:59 PM |
Tagged: radeon, amd, video, pitcairn, hd 7870 ghz edition, hd 7870

There have been quite a few new graphics card releases this year and with the now crowded GPU market, we have gotten many requests to revisit some of the earlier launches to see how they stack up in the latest GPU landscape.  One such card is AMD’s Radeon HD 7870 GHz Edition, which has seen some dramatic improvements since its initial release in March. 

AMD’s entire lineup of graphics cards based on the Southern Islands architecture were released between the months of January and March of this year, with only a few updates during the summer to combat new releases from NVIDIA.  Though they don’t get as much review time anymore, the Tahiti, Pitcairn and Cape Verde GPUs still have a lot to offer gamers and the Radeon HD 7870 GHz Edition is a perfect example of that.

Thanks to recent price cuts, the Sapphire Radeon HD 7870 GHz Edition and all other Pitcairn GPUs can be found for much less than when they were launched.  With a starting price of $350 in March, some base HD 7870s can be found online for $250 and sometimes less with rebates today making it a great deal for gamers on a budget. 

You can check out all of our graphics card reviews right here to see how the market currently stands but there are really very few bad choices anymore.

Factory Overclocked MSI GTX 660 HAWK Pictured

Subject: Graphics Cards | September 22, 2012 - 04:01 AM |
Tagged: nvidia, MSI GTX660 HAWK, msi, gtx 660

This week has certainly had its share of leaked graphics card news, and the latest information on that market indicates that MSI is working on a enthusiast-level HAWK version of the GTX 660 GPU. That card will take the GK106 Kepler chip to the max with the fastest factory overclocks yet.

Last week Nvidia debuted its GTX 660 graphics card, which is currently the lowest-end GPU to use the Kepler GK106 chip. Once the NDA broke, the review of the card went live, and the performance of the reference designs was analyzed.

GK106 features 5 SMX units in 2.5 Graphics Processing Clusters (GPC), which Nvidia has said is the most that the chip will ever have. The GTX 660 version has 960 CUDA cores, 80 texture units, 24 ROPs, and a 192-bit memory bus.

While GK106 will likely not see a version with three complete GPCs, the mid-range Kepler chip still has a bit of performance headroom that can be unleased with overclocking, and several OEMs are preparing factory overclocked GTX 660 graphics cards with custom coolers.

The latest custom GTX 660 to be leaked is the MSI GTX 660 HAWK edition with out-of-the-box overclocked settings, beefed up power management hardware, and a TwinFrozr IV cooler. 

GTX-660-HAWK-MSI.jpg

MSI has gone with a custom PCB and cooler to keep the GK106 fed with power and running cool. The PCB has been fitted with a 10-phase VRM, SSC chokes, and IR DirectFETs to provide the power needed to run at overclocked settings. Of course, MSI has included its GPU Reactor hardware – a feature exclusive to its HAWK branded cards that differentiates them from the lower tier lightning and power edition cards. The GPU Reactor is a set of tantalum capacitors that are said to deliver more stable voltage to the Kepler chip.

The graphics card continues to be powered by two 6-pin PCI-E power connectors. MSI has also added a dual BIOS feature to the HAWK card that will run the GPU at GTX 660 reference speeds (980/1033MHz) or at the overclocked profile, depending on physical BIOS switch position.

Clockspeeds are where the MSI GTX 660 HAWK really gets interesting, however. The base clockspeed of 1100MHz is more than most GTX 660 cards run at /boost/ speeds, and the 1176MHz boost speed is the fastest boost speed we’ve seen yet. In an interesting twist, MSI has not touched the clockspeed for the 2GB of GDDR5 memory. Instead, it has left the graphics card clocked at 6008MHz memory (the reference speed). It may be that the memory chips simply cannot overclock much beyond the reference clockspeeds as there are no other factory overclocked GTX 660s that I know of that push the memory clocks beyond reference.

MSI-GTX-660-HAWK-Front.jpg

Of course, the other big selling point of this MSI card is the custom cooler – one that Josh seems to like thanks to the addition of “supa pipes!” The Twin Frozr IV is a dual fan cooled aluminum fin array that is connected to the block over the GPU by five heat-pipes. There does not appear to be much information on the HSF beyond that, unfortunately. Judging by past iterations, it should be more than capable of running at the factory overclocked speeds, however.

Display outputs will include two DVI, one DisplayPort, and one HDMI. Pricing and availability are still unknown, but expect it to command a small premium over the standard GTX 660’s $229 price tag.

EXPreview was the source of the photos, however the webpage seems to be down at the moment. Fortunately, WCCF Tech manged to grab them before the original page was lost, and you can see more photos of the MSI GTX 660 HAWK (SKU: N660GTX HAWK) on that page.

Details Leak on AMD's Sea Islands HD 8900 Series Graphics Cards

Subject: Graphics Cards | September 21, 2012 - 02:55 PM |
Tagged: tenerife, Sea Islands, radeon, GCN, amd, 8970

(Updated to add additional information on the 8900 series rumors – mainly on Radeon 8950.)

Earlier this week, we reported on rumors of two upcoming mid-range AMD 8800 series graphics cards based on the Sea Islands architecture. As mentioned previously, Sea Islands is the successor to the Southern Islands architecture used on the 7000 series. It features an improved Graphics Core Next GPU processor architecture based on TSMC's 28nm process. With that said, the chip will draw less power and be faster on GPGPU workloads thanks to several efficiency tweaks. Graphics cards based on Sea Islands will support DirectX 11, and will be available early next year.

AMD Radeon HD 8970 Tenerife Sea Islands GPU.jpg

While the 8850 and 8870 are based on the Oland GPU, this newly leaked Radeon HD 8970 will use the "Sea Islands" Tenerife GPU. New information seems to suggest that AMD will actually brand it the Venus XTX for 8970 cards and Venus XT/Pro for 8950 cards, though Oland would remain the chip name for 8800 series cards.

Tenerife offers up some impressive (but realistic) specifications, including 2,560 shaders, 160 texture units, 48 ROPs, and a relatively massive 384-bit memory bus. Also impressive is an alleged transistor count of 5.1 billion, which puts it a great deal above the Radeon 7970's 4.31 billion transistors. This rumored Tenerife/Venus XTX GPU (whichever AMD ends up calling it) will have a 250W TDP and will be use in the 8970 flagship graphics card. Venus XT/Pro will scale back the chip a bit by featuring 2,304 shaders, 144 texture units, and 32 ROPs. No word yet on what the TDP will be.

Both the HD 8970 and HD 8950 are said to support 3GB of GDDR5 memory running at 6GHz on a 384-bit bus, which works out such that the cards have approximately 322 GB/s of bandwidth! Further, the 16 additional ROP units in the Radeon HD 8970 will give it a nice performance boost over the 8950 and 8800 series, especially when running multiple monitors in Eyefinity configurations.

As far as specifications go, we do not yet know the die size of the GPU or what the GPU base (and boost) clockspeeds are beyond a source indicating the boost frequency of the 8970 will be above 1050 MHz. According to PC Perspective's GPU packrat reviewer Josh Walrath, the Tenerife GPU will have a much larger die than that of Oland. Because it will feature a sizeable increase in number of transistors, but still be based on a 28nm process, the die size will be somewhere between 380mm^2 and 420mm^2.

To put that in perspective, the 8850/8870 has a die size of 270mm^2, and the current generation predecessor (7950/7970) has a die size of only 365mm^2.

The following chart compares the various rumored Radeon 8000-series graphics cards to their previous generation counterparts.

  Radeon HD 7850 Radeon HD 8850 Radeon HD 7870 Radeon HD 8870 Radeon 7950 Radeon 8950 Radeon HD 7970 Radeon HD 8970
Die Size 212mm^2 270mm^2 212mm^2 270mm^2 365mm^2 ~400mm^2 365mm^2 ~ 400mm^2 
Shader Count 1024 1536 1280 1792 1792 2304 2048 2560
TMUs 64 96 80 112 112 144 128 160
ROPs 32 32 32 32 32 32 32 48
Memory Interface 256-bit 256-bit 256-bit 256-bit 384-bit 384-bit 384-bit 384-bit
Bandwidth 153.6 GB/s 192 GB/s 153.6 GB/s 192 GB/s 240 GB/s 322 GB/s 288 GB/s 322 GB/s

*Tenerife die size is estimate only, actual die size is still unknown.

The AMD Radeon HD 8970 will be AMD's next generation single-GPU flagship graphics card, and it looks to offer up some respectable hardware. The Radeon HD 8950 should be a decent step up in performance versus the 7950, though it would have been nice to see the 8970's additional ROP units stick around in the 8950. Unfortunately we do not know what this Tenerife (aka Venus) GPU-based  graphics card will be priced at. For now, we will just have to be cautiously optimistic and wait a few months to see how much this card will cost. The wait should not be very long either, if rumors are true as they seem to indicate that the 8970 will enter manufacturing in late 2012 and launched in early (January/February) 2013.

Fastest isn't necessarily best when it comes to GTX 660s

Subject: Graphics Cards | September 20, 2012 - 04:35 PM |
Tagged: overclock, gtx 660, DirectCU II, asus

As promised [H]ard|OCP has spent some time overclocking the ASUS GTX 660 DirectCU II card and have come back with their results.  The highest GPU clock they managed was a reported 1170MHz Boost clock in GPU Tweak but which was 1215MHz in actual in-game performance.  While that was the high speed record it did not provide the best performance as the frequency often dipped much lower because of the heat produced, [H]'s sweet spot was actually a 1100MHz Boost clock, in-game a much more steady 1152MHz though it did still dip occasionally.  They also upped the memory, but again because of the heat produced by the overclock they could not raise voltage without negative consequences.  Check the whole review here.

"We put our new ASUS GeForce GTX 660 through the ringer of overclocking and make real world gaming comparisons. If you are thinking the new GTX 660 (GK106) GPU will be a good overclocker like its bigger brother GK104, you may be in for a surprise that puts the new GTX 660 in a new light."

AMD Sea Islands HD 8850 and 8870 Specifications Leaked

Subject: Graphics Cards | September 18, 2012 - 06:34 PM |
Tagged: Sea Islands, oland, hd8870, hd8850, gpu, amd radeon, amd

AMD beat NVIDIA to the punch with its 7000-series “Southern Islands” graphics cards, and if the rumors hold true the company may well accomplish the same feat with its next generation architecture. Codenamed Sea Islands, the architecture of AMD’s 8800-series is set to (allegedly) debut around January 2013 time frame. Featuring DirectX 11, GPGPU and power efficiency improvements, 3.4 billion transistors on a 28nm process, and a rumored sub-$300 price, will the 8850 and 8870 win over enthusiasts?

AMD Sea isnlands Road Map.jpg

AMD launched its Southern Island graphics cards with the Graphics Core Next (GCN) architecture and Pitcairn GPU in March of this year. Since then NVIDIA has moved into the market with the 660 and 660Ti, and budget gamers have lots of options. However, yet another budget gaming GPU from AMD will be coming in just a few months if certain sources' leaks prove correct. The 8850 and 8870 graphics cards are rumored to launch in January 2013 for under $300 and offer up some significant performance and efficiency improvements. Both the 8850 and 8870 GPUs are based on the Oland variant of AMD’s Sea Islands architecture. As a point of reference, AMD’s 7850 and 7870 are using the Pitcairn version of AMD’s Southern Islands architecture – thus Sea Islands is the overarching architecture and Oland is an actual chip based on it.

Sea Islands is essentially an improved and tweaked Graphics Core Next design. It will continue to utilize TSMC's 28 nm process, but will require less power than the 7000-series while being much faster. While the specifications for the top-end 8900-series is still up in the air, Videocardz is claiming sources in the know have supplied the following numbers for the mid-range 8850 and 8870 Oland cards. 

AMD Radeon HD8870 and Radeon HD8850.png

Videocardz put together a table comparing AMD's current and future GPU series.

The GPU die size has reportedly increased to 270mm^2 (squared) versus the 7850/7870’s 212mm^2 die. This increase is the result of AMD packing an additional 600 million transistors for a total of 3.4 billion. 3D Center further breaks the GPU down in stating that the 8870 will feature 1792 shader units, 112 texture manipulation units (TMU), 32 ROPs, and support a 256-bit memory interface. The 8850 graphics card will scale the Oland GPU down a bit further by featuring only 1536 shader units and 96 TMUs, but keeping the 32 ROPs and 256-bit interface.

For comparison, here’s a handy table comparing the 8850/8870 to the current-generation 7850/7870 (which we recently reviewed).

  Radeon HD 7850 Radeon HD 8850 Radeon HD 7870 Radeon HD 8870
Die Size 212mm^2 270mm^2 212mm^2 270mm^2
Shader Count 1024 1536 1280 1792
TMUs 64 96 80 112
ROPs 32 32 32 32
Memory Interface 256-bit 256-bit 256-bit 256-bit
Bandwidth 153.6 GB/s 192 GB/s 153.6 GB/s 192 GB/s

 

So while the memory bus and number of ROP units is staying the same, you are getting more shaders and texture units along with a boost to the overall memory bandwidth with the larger die size – sounds like an okay compromise to me!

AMD has managed to increase the clock speeds and GPGPU performance with Oland/Sea Islands as well. On the clockspeed front, the 8850 has a base boost GPU clockspeed of 925 MHz and 975 MHz respectively. Further, the 8870 has base/boost clocks of 1050 MHz/1100 MHz. That is a nice improvement over the 7850’s 860 MHz clockspeed, and 7870’s 1000 MHz clockspeed. AMD is also adding its PowerTune with Boost functionality to the Oland-based graphics cards which is a welcome addition. The theoretical computational power of the graphics chips has been increased as well, by as much as 75% for single precision and 60% for double precision (7870 to 8870). The single precision performance has been increased to 2.99 TFLOPS on the 8850 (1.76 TFLOPS on the 7850), and 3.94 TFLOPS on the 8870 (7870 has 2.25 TFLOPS). The single precision numbers are relevant to gaming and general applications that consumers would run that are GPU accelerated. The figures are not really suited/representative of high performance computing (HPC) workloads where precision is important (think simulations and high-end mathematics), and that is where the double precision numbers come in. The 8800 series gets a nice boost in potential performance as well, topping out at 187.2 GFLOPS for the 8850 and 246 GFLOPS for the 8870. That is in comparison the 7850’s 110 GFLOPS and 7870’s 160 GFLOPS.

The sources also disclosed that while the 8850 would have the same TDP (thermal design power) rating as the 7850, the higher-end 8870 would actually see a decreased 160W TDP versus the previous generation’s 175W. Unfortunately, there were not any specific power draw numbers talked about, just that the cards were more power efficient, so it remains to be seen just how much (if at all) less power the GPUs will need. The sources put the 8870 at the same performance level as the NVIDIA GeForce GTX 680, which would mean that this will be an amazing mid-range card if true. Especially considering that the cards have a rumored price of $279 for the 8870 and $199 for the 8850. Granted, those prices are likely much lower than what we will actually see if AMD does indeed launch the cards in January as the company will not have competition from NVIDIA’s 700 series right away.

In some respects, the rumored specifications seem almost too good to be true, but I’m going to remain hopeful and am looking forward to not only seeing the mid-range Oland GPU coming out, but the unveiling of AMD’s top-end 8900 series (which should be amazing, based on the 8800-series rumors).

What do you think of the rumored 8850 and 8870 graphics cards from AMD? Will they be enough to temp even NVIDIA fans?
