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.
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.
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!]

PhysX Settings Comparison
Borderlands 2 is a hell of a game; we actually ran a 4+ hour live event on launch day to celebrate its release and played it after our podcast that week as well. When big PC releases occur we usually like to take a look at performance of the game on a few graphics cards as well to see how NVIDIA and AMD cards stack up. Interestingly, for this title, PhysX technology was brought up again and NVIDIA was widely pushing it as a great example of implementation of the GPU-accelerated physics engine.
What you may find unique in Borderlands 2 is that the game actually allows you to enabled PhysX features at Low, Medium and High settings, with either NVIDIA or AMD Radeon graphics cards installed in your system. In past titles, like Batman: Arkham City and Mafia II, PhysX was only able to be enabled (or at least at higher settings) if you had an NVIDIA card. Many gamers that used AMD cards saw this as a slight and we tended to agree. But since we could enable it with a Radeon card installed, we were curious to see what the results would be.
Of course, don't expect the PhysX effects to be able to utilize the Radeon GPU for acceleration...
Borderlands 2 PhysX Settings Comparison
The first thing we wanted to learn was just how much difference you would see by moving from Low (the lowest setting, there is no "off") to Medium and then to High. The effects were identical on both AMD and NVIDIA cards and we made a short video here to demonstrate the changes in settings.

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 | Tim Verry
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.
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.
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 | Tim Verry
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.
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 | Jeremy Hellstrom
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 | Tim Verry
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 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.
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?

Lucid Dynamix adjusts mobile gaming quality in real-time

Lucid has a history of fast product development as a software company. It wasn't too long ago that Lucidlogix was a fabless semiconductor company that made chips for motherboards to enabled multi-GPU solutions across card models and GPU vendors. Since then we have seen them move to GPU virtualization tasks like enabling discrete and integrated GPUs to work seamlessly without user interaction on the same notebook.
The Lucid MVP software is the most recent version of that track and it has been very well received, find its way onto most motherboard brands and recently the Origin gaming notebook line.
While huddling in San Francisco during IDF, we stopped by Lucid's suite to see what new stuff they were cooking up. One of the products was called Dynamix and it has the goal of adjusting the image quality of games in real time to help users hit minimal gaming experience levels. Lucid isn't adjusting the settings on your games but rather is intercepting calls from the game to the graphics solution (integrated or discrete) and altering them slightly to adjust performance.
Above you'll see the beta user interface for Dynamix that allows the user to configure it and assign which titles it should operate on. Two sliders, one for a frame rate and one for a somewhat subjective "quality" level can be moved in order to alter the algorithms Lucid has set in the place.
When you set the minimum frame rate, that is the "threshold" with which you would like to make sure all of your games run at. The default was 30 FPS when I played with it and left the quality slider where it started as well. If you start a game that does NOT run at 30 FPS with the settings you have (or maybe it won't with any settings) Lucid's software will attempt to change some quality and rendering settings completely transparently to bring the frame rate up.
In our demo we saw Crysis 2 running on a Dell Ultrabook at 1366x768 and a reported frame rate of 9 from FRAPS. Obviously a game at that frame rate is pretty much unplayable, so when you enable the Dynamix software via a hotkey it attempts to bring up the frame rate; not by adjusting settings in the game engine but rather by changing DX calls to the GPU itself.
Examples given were that Dynamix might change the color depth requested by the game, or it might lower the texture resolutions and anti-aliasing passes. It gradually degrades image quality until it is close to reaching your desired minimum frame rate. When I enabled it on Crysis 2, my frame rate went from 9 to 28 or so - a sizeable difference that made the game mostly playable.
It's not magic though - there are degradations in quality that are visible.
Here you can see a close up of the game running without Dynamix at work. The quality is good but the frame rate was again at 9 FPS or so.
This image shows the game after enabling Dynamix, with a frame rate of 28 or so. You can definitely see blurrier textures, less sharpness around the gun and the foliage quality has gone done some as well.
So why is this even interesting? There are several reasons. First there are some games that may not have quality settings low enough to run on an Ultrabook with HD 2500 graphics; kind of like Crysis 2. Lucid is able to change things that the developer might not have thought of (or might not have wanted) with its access to the graphics pipeline.
Secondly, as the name implies, the software is dynamic. If you already running a game OVER your minimum threshold then the software will not change anything. But if you are running in an indoor area at 40 FPS and then drop to 20 FPS when you go outdoors, the software will kick in and attempt to adjust quality to get you back up to the 30 FPS mark.
Finally, the UI remains untouched - the informational points that were part of the game's interface were untouched so you don't have to worry about blury text or anything like that. Lucid's capability to know about the back end of the 3D engines allows them to tweak things like this pretty easily.
Lucid says the goal is to make games that would otherwise be unplayable on a system, playable for consumers. Without a doubt the target is Sandy Bridge and Ivy Bridge notebooks and the somewhat limited performance of the HD 2500 graphics system. While this could also be applied to discrete graphics system from AMD and NVIDIA, I don't see that being necessary.
Currently the software works with DX9 and DX10 games though they are still working to get DX11 covered completely. And while the software worked find our demo, we only tried out one game on one notebook - there is still a lot of proving that Lucid needs to do for us to buy in completely. If Lucid's bragging was anything to judge by though you should see Dynamix in quite a few major notebook brands later this year.
What do YOU think? Is this a technology you are interested in and do you see a place for it?
