Scott Wasson from The Tech Report and Ryan have been discussing the microstuttering present in Crossfire and while Ryan got his hands on the hardware to capture the raw output first, The Tech Report have been investigating this issue as in depth as Ryan and Ken have been.  Their look at the new Catalyst and the effects of Frame Pacing show the same results as you saw yesterday in Ryan's article; for essentially no cost in performance you can get a much smoother experience when using a CrossFire system on a single display.  In their article they have done a great job of splicing together videos of runthroughs of several games with the Frame Pacing disabled on one side and enabled on the other, allowing you to see with your own eyes the difference in game play, without having to have your own Crossfire system.

New NVIDIA 326.41 Beta Graphics Drivers Add Shield PC Game Streaming Support

Subject: Graphics Cards | August 2, 2013 - 02:50 AM |
Tagged: graphics drivers, nvidia, shield, pc game streaming, gaming, geforce

NVIDIA recently released a new set of beta GeForce graphics card drivers targetted at the 400, 500, 600, and 700 series GPUs. The new version 326.41 beta drivers feature the same performance tweaks as the previous 326.19 drivers while baking in beta support for PC game streaming to NVIDIA’s Shield gaming portable from a compatible GeForce graphics card (GTX 650 or better). The new beta release is also the suggested version to use for those running the Windows 8.1 Preview.

NVIDIA has included the same performance tweaks as version 326.19. The tweaks offer up to 19% performance increases, depending on the particular GPU setup. For example, users running a GTX 770 will see as much as 15% better performance in Dirt: Showdown and 6% in Tomb Raider. Performance improvements are even higher for GTX 770 SLI setups, with boosts in Dirt: Showdown and F1 2012 of 19% and 11% respectively. NVIDIA has also added SLI profiles for Splinter Cell: Blacklist and Batman: Arkham Origins.

The NVIDIA Shield launched recently and reviews are making the rounds around the Internet. One of the exciting features of the Shield gaming handheld is the ability to stream PC games from a PC with NVIDIA graphics card to the Shield over Wi-Fi.

The 326.41 drivers improve performance across several games on the GTX 770.

The other major changes are improvements to tiled 4K displays, which are displays with 4K resolutions that are essentially made of two separate displays, and the monitor even shows up to the OS as two separate displays despite being in a single physical monitor. Using DisplayPort MST and tiled displays allows monitor manufacturers to deliver 4K displays with higher refresh rates.

Extreme Windows, Extreme Eyefinity, 11,520 x 2160 Gaming

Subject: General Tech, Graphics Cards, Displays | July 25, 2013 - 07:32 PM |
Tagged: eyefinity, crossfire, 4k

Sharp recently sampled a few of their 32" 4K monitors to Microsoft's Extreme Windows. The blog, known for editorializing what enthusiasts can do with Microsoft products, combined three 3840 x 2160 monitors into a 3x1 Eyefinity configuration at 60 Hz; the screen, itself, measures about 7 feet diagonally. This configuration, unlike the already-supported three-display 30 Hz and single-display 60Hz 4K modes, required AMD to develop a customized driver before Sharp's repo-team reclaimed their $15,000 worth of monitors.

They had a day until their door was to be knocked.

4k-eyefinity-01.jpg

The system, three Radeon HD 7970s in Crossfire, successfully drove... they were playing Dirt 3, by the way... the three monitors at 60 Hz with between 62 and 70, of software recorded, FPS. 11,520 x 2160, at 60 Hz, requires 1.5 billion colors to be calculated within a second of animation; that is 1.5 gigapixels. Ignore, for a moment, stutter caused by including Crossfire with an Eyefinity setup. Every calculation, whether properly drawn to the monitor or not is, and must be, performed; 1.5 gigapixels is impressive and an accomplishment for Radeon hardware.

4k-eyefinity-02.jpg

Lastly, I need to call out drama as I see it: power supplies. It is not hard to find a PSU which can support a three-GPU system and no reason for it to be hanging outside the case. It might give off the bleeding-edge appearance, but this is not arc welding. If they really were concerned, they could have picked up a higher capacity device from the shelf of a local component reseller.

Unreal Engine 4 on Mobile Kepler at SIGGRAPH

Tagged: Siggraph, kepler, mobile, tegra, nvidia, unreal engine 4

SIGGRAPH 2013 is wrapping up in the next couple of days but, now that NVIDIA removed the veil surrounding Mobile Kepler, people are chatting about what is to follow Tegra 4. Tim Sweeney, founder of Epic Games, contributed to NVIDIA Blogs the number of ways that certain attendees can experience Unreal Engine 4 at the show. As it turns out, NVIDIA engineers have displayed the engine both on Mobile Kepler as well as behind closed doors on desktop PCs.

Not from SIGGRAPH, this is a leak from, I believe, GTC late last March.

Also, this is Battlefield 3, not Unreal Engine 4.

Tim, obviously taking the developer standpoint, is very excited about OpenGL 4.3 support within the mobile GPU. In all, he did not say too much of note. They are targeting Unreal Engine 4 at a broad range of platforms: mobile, desktop, console, and, while absent from this editorial, web standards. Each of these platforms are settling on the same set of features, albeit with huge gaps in performance, allowing developers to focus on a scale of performance instead of a flowchart of capabilities.

Unfortunately for us, there have yet to be leaks from the trade show. We will keep you up-to-date if we find any, however.

NVIDIA Launches Flagship Quadro K6000 Graphics Card For Visual Computing Professionals

Subject: Graphics Cards | July 23, 2013 - 09:00 AM |
Tagged: workstation, simulation, quadro k6000, quadro, nvidia, k6000, gk110

Today, NVIDIA announced its flagship Quadro graphics card called the K6000. Back in March of this year, NVIDIA launched a new like of Quadro graphics cards for workstations. Those cards replaced the Fermi-based predecessors with new models based on NVIDIA’s GK-104 “Kepler” GPUs. Notably missing from that new lineup was NVIDIA Quadro K6000, which is the successor to the Quadro 6000.

NVIDIA Quadro K6000 GK110 GPU.jpg

Contrary to previous rumors, the Quadro K6000 will be based on the full GK110 chip. In fact, it will be the fastest single-GPU graphics card that NVIDIA has to offer.

The Quadro K6000 features a full GK110 GPU, 12GB of GDDR5 memory on a 384-bit bus, and a 225W TDP. The full GK110-based GPU has 2,880 CUDA cores, 256 TMUs, and 48 ROPs. Unfortunately, NVIDIA has not yet revealed clockspeeds for the GPU or memory.

NVIDIA Quadro K6000 GK110 GPU Specifications Comparison.jpg

Thanks to the GPU not having any SMX units disabled, the NVIDIA Quadro K6000 is rated for approximately 1.4 TFLOPS of peak double precision floating point performance of and 5.2 TFLOPS of single precision floating point performance.

The chart below illustrates the differences between the new flagship Quadro K6000 with full GK110 GPU and the highest tier Tesla and consumer graphics cards which have at least one SMX unit disabled.

NVIDIA GK110-Based Graphics Cards

  Quadro K6000 Tesla K20X GTX TITAN
CUDA 2,880 2,688 2,688
TMUs 256 224 224
ROPs 48 48 48
Memory 12GB 6GB 6GB
Memory Bus 384-bit 384-bit 384-bit
Memory Bandwidth 288 GB/s 250 GB/s 288 GB/s
Single Precision FP 5.2 TFLOPS 3.95 TFLOPS 4.5 TFLOPS
Double Precision FP ~1.4 TFLOPS 1.31 TFLOPS 1.31 TFLOPS

The NVIDIA GTX TITAN gaming graphics card has 2,688 CUDA cores, 224 TMUs, and 48 ROPs and is rated for peak double and single precision of 1.31 TFLOPS and 4.5 TFLOPS respectively. On the other hand, the lower-clocked Tesla K20X compute accelerator card has 2,688 CUDA cores, 224 TMUs, and 48 ROPs along with lower clockspeeds on the memory and GPU. Because of the lower clockspeeds, the K20X is rated for double and single precision floating point performance of 1.31 TFLOPS and 3.95 TFLOPS and memory bandwidth of 250GB/s versus the 288GB/s bandwidth on the TITAN and K6000.

NVIDIA® Quadro® K6000 GPU

In all, the new K6000 is an impressive card for professional users, and the GK110 chip should perform well in the workstation environment where GK104 was the only option before. NVIDIA claims that the GK110 is up to 3-times the performance of the Quadro 6000 (non K) predecessor. It is also the first Quadro GPU with 12GB of GDDR5 memory, which should lend itself well to high resolutions and artists working with highly detailed models and simulations.

Specifically, NVIDIA is aiming this graphics card at the visual computing market, which includes 3D designers, visual effects artists, 3d animation, and simulations. The company provided several examples in the press release, including using the GK110-based card to render nearly complete photorealistic vehicle models in RTT Deltagen that can run real time during design reviews.

The Quadro K6000 allows for larger and fully populated virtual sets with realistic lighting and scene detail when 3D animators and VFX artists are working with models and movie scenes in real time. Simulation work also takes advantage of the beefy double precision horsepower to support up to 3-times faster simulation run times in Terraspark's InsightEarth simulation. Users can run simulations with wider areas in less time than the previous generation Quardo cards, and is being used by oil companies to determine the best places to drill.

Pixar's Vice President of Software and R&D Guido Quaroni had the following to say regarding the K6000.

"The Kepler features are key to our next generation of real-time lighting and geometry 
handling. The added memory and other features allow our artists to see much more of the 
final scene in a real-time, interactive form, which allows many more artistic iterations."

The K6000 is the final piece to the traditional NVIDIA Quadro lineup and is likely to be well recieved by workstation users that need the increased double precision performance that GK110 offers over the existing GK104 chips. Specific pricing and availability are still unknown, but the K6000 will be available from workstation providers, system integrators, and authorized distribution partners beginning this fall.

Tagged: Samsung, mali, exynos

Exynos, the line of System on a Chip (SoC) products from Samsung, were notably absent of ARM Mali GPUs. This, apparently, struck concern over how viable Mali will continue to be and whether ARM will continue to lose designs to competitors such as Imagination Technologies.

ARM-Mali-T628.jpg

Then Samsung announced, Monday evening for us North Americans, the upcoming Exynos 5 Octa Processor will embed six ARM Mali-T628 GPU cores. The T628 GPU cores are capable of OpenCL 1.1 and OpenGL ES 3.0 standards which should allow applications to offload heavy batches of tasks, such as computational photography processing, with high efficiency and performance.

The Exynos 5 Octa contains four ARM Cortex-A15 cores at 1.8GHz, supported by four additional Cortex-A7 cores clocked at 1.3GHz. These processors are currently being sampled and should be produced in August.

Sapphire appears to be preparing to unleash a factory overclocked dual GPU card called the Radeon HD 7990 Atomic. EXPReview managed to uncover several photos and specification details of the upcoming graphics card. It is quite an impressive card, that features a custom PCB, beefy power delivery electronics, 6GB of total GDDR5, and (best of all) two AMD Radeon HD 7970 GPUs cooled by a full cover closed loop water cooler!

Sapphire-Radeon-HD-7990-Atomic-_1.jpg

The Sapphire HD 7990 Atomic is based around a custom 12-layer PCB. The card also features an 18-phase VRM, 50A chokes, LFPAK MOSFETS, and Tantalum capacitors. Sapphire has divided the total 18-phase VRM up such that each GPU and 3GB of memory gets 6+2+1 power phases. Of course, the HD 7990 Atomic uses two AMD Radeon HD 7970 GHz Edition GPUs for a total of 4,096 stream processors.

Sapphire has not released clockspeed information, but it should be overclocked significantly beyond the company’s existing dual gpu 7990 card’s base and boost clockspeeds of 950 MHz and 1000 MHz.

Other features include a PLX PEX8747 PCI-E 3.0 bridge chip that connects the two 7970 GPUs together, a dual BIOS switch that will allow users to run the 7990 at stock or at overclocked speeds, and a single crossfire connector to enable quad-Crossfire multi-GPU setups. The graphics card is powered by three 8-pin PCI-E power connectors. Finally, it provides six mini-DisplayPort video outputs.

Sapphire-Radeon-HD-7990-Atomic-Water Cooler.jpg

In order to effectively cool the factory overclocked card, Sapphire is bundling a pre-installed self-contained liquid cooler. The closed loop cooler consists of a full cover water block on the HD 7990 Atomic, a 240mm radiator with two 120mm fans, and a combination pump and reservoir that fits within a 5.25” optical drive bay.

Naturally, how much this card will cost and where it will be available is still unknown. With that said, ChipLoco indicates that the card is coming sometime within the “next few weeks.” The extent of the factory overclock is also unknown. It is definitely a high end card worthy of enthusiasts and overclockers. Unfortunately, it utilizes a custom PCB, so it may be difficult to find alternative blocks should users wish to integrate it into their existing custom water loops.

It would appear that NVIDIA was paying attention to our recent live stream where we unboxed and setup our new ASUS PQ321Q 4K 3840x2160 monitor.  During our setup on the AMD and NVIDIA based test beds I noticed (and the viewers saw) some less than desirable results during initial configuration.  The driver support was pretty clunky, we had issues with reliability of booting and switching between SST and MST (single and multi stream transport) modes caused the card some issue as well. 

4kdriver.png

Today NVIDIA released a new R326 driver, 326.19 beta, that improves performance in a couple of games but more importantly, adds support for "tiled 4K displays."  If you don't know what that means, you aren't alone.  A tiled display is one that is powered by multiple heads and essentially acts as multiple screens in a single housing.  The ASUS PQ321Q monitor that we have in house, and the Sharp PN-K321, are tiled displays that use DisplayPort 1.2 MST technology to run at 3840x2160 @ 60 Hz. 

It is great to see NVIDIA reacting quickly to new technologies and to our issues from just under a week gone by.  If you have either of these displays, be sure to give the new driver a shot and let me know your results!

Tagged: xfx, HD 7790 Black Edition

The XFX Radeon HD 7790 Black Edition has several advantages over a regular HD 7790, a factory overclock of 75MHz to 1075MHz on the GPU and an effective 6.4GHz on the memory, of which there is twice the amount as a regular 1GB model.  To go along with the overclock is XFX's Double Dissipation custom cooling and components which they refer to as Duratec Professional Grade, which helped [H]ard|OCP reach speeds of 1230MHz GPU and 7GHz GDDR5 when overclocking with no noticeable change in temperatures.  This is rather impressive performance for a card who's smaller brother costs only $140 after MIR, the pricing of the 2GB model should be only $20 more than that.  Unfortunately for AMD, at the end of the day [H] cannot recommend this card over the euqally expensive but higher performing GeForce GTX 650 Ti Boost 2GB.

H_BE.jpg

"Today we are strapping the XFX Radeon HD 7790 Black Edition to our test bench and pitting it against a GeForce GTX 650 Ti Boost. Each card is equipped with 2GB of GDDR5 and is attractively priced for the value minded gamer. The gloves will come off and we will find out whether the Black Edition is worthy of a Black Belt or a Black Eye."

Tagged: msi, gtx 770, GK104, gk-104, gaming, factory overclocked, 4GB

MSI recently announced the GTX 770 Gaming 4GB which combines a factory overclocked GK-104 GPU with 4GB of GDDR5 memory and the company’s Twin Frozr IV cooler on a custom PCB. This card joins the existing MSI GTX 770 with 2GB of memory in the company’s GPU lineup.

MSI GeForce GTX 770 Gaming 4GB Graphics Card N770 TF 4GD5slashOC.jpg

Specifications the new graphics card include a GK-104 based GTX 770 GPU with a base clock of 1137 MHz and a GPU Boost clockspeed of 1189 MHz. This compares to the 4GB Zotac GTX 770’s base and boost clockspeeds of 1059 MHz and 1098 MHz and to the reference NVIDIA GTX 770’s 1046 MHz base and 1085 MHz boost. In short, the upcoming MSI card is one of the fastest-clocked models with 4GB of memory. Unfortunately, that 4GB of GDDR5 does not come factory overclocked, and is instead left at the stock 7 GHz clockspeed.

MSI GeForce GTX 770 Gaming 4GB Graphics Card Breakout.jpg

Further, the MSI card is cooled by the company’s Twin Frozr IV cooler. This HSF features two 100mm fans that cool an aluminum fin stack. In turn, that fin stack attaches to the GPU block via five heatpipes. There is no backplate, but the card does have a reinforcing plate between the PCB and cooler (which also, likely, helps dissipate a small bit of the heat generated by the VRMs and RAM).

The card is essentially the same card as the existing 2GB version, which is not necessarily a bad thing. The model number on the 4GB card is N770 TF 4GD5/OC. MSI has not released pricing or availability, but expect it to be around $430 and up for grabs later this summer.

Tagged: powercolor, devil hd 7870, hd 7870, amd, GCN

Nearly a year ago, PowerColor launched the massive “Devil 13” Radeon HD 7990 graphics card. Now, the company is releasing a new Devil-series single GPU card called the Devil HD 7870. This card combines a huge dual slot, triple fan HSF with a factory overclocked Graphics Core Next-based Radeon HD 7870 GPU.

Powercolor Devil HD 7870 Graphics Card.jpeg

The upcoming Devil HD 7870 features a factory overclocked 7870 “Pitcairn” GPU clocked at 1100 MHz and 2GB of GDDR5 clocked at 1250 MHz. As a refresher, the 7870 has 1,280 stream processors, 80 Texture Units, and 32 ROPs along with a 256-bit memory bus. The reference AMD Radeon HD 7870 graphics card has a GPU clockspeed of 1000 MHz and memory clockspeed of 1200 MHz.

To differentiate its card, PowerColor is pairing the factory overclocked GPU and memory with a triple fan (four heatpipe and aluminum fin stack) cooler similar in design to the Devil 13’s HSF. The card also features PowerColor’s “Platinum Power Kit” which entails a 7+1+1 power phase with digital VRMs and so-called “Super Capacitors.” PowerColor claims that its triple fan cooler runs 25% cooler and 18% quieter than the reference AMD cooler.

Powercolor Devil HD 7870.jpeg

The Devil HD 7870 offers up a DL-DVI, DVI, HDMI, and two Mini-DisplayPort video outputs. It is powered by two 6-pin PCI-E power connectors.

There is no word on pricing or availability, but expect the Devil-branded card to come at a premium (possibly around $270 MSRP).

Sapphire Launches Two Budget Cape Verde LE HD 7730 Graphics Cards

Subject: Graphics Cards | July 14, 2013 - 06:07 AM |
Tagged: sapphire, hd 7730, GCN, cape verde le, cape verde, 7730

Sapphire has launched its own budget card based on AMD’s Cape Verde LE GPU called the HD 7730. In fact, Sapphire is launching two 7730 SKUs with differing amounts (and types) of on board memory. Specifically, Sapphire is launching a Radeon HD 7730 with 1GB of GDDR5 and a HD 7730 with 2GB of GDDR3 (yes, you read that correctly, the second SKU comes with 2GB of GDDR3 memory).

Sapphire Radeon HD 7730 Cape Verde LE Budget PCI-E Graphics Card GCN.jpg

The HD 7730 is based on the Cape Verde LE GPU, which is similar to the Cape Verde chip used in the 7750 and 7770 graphics cards minus a set of stream processors. The Graphics Core Next-based HD 7730 comes with 384 stream processors clocked at 800 MHz and 128-bit memory bus. From here, the two SKUs differ. One Sapphire card comes with 1GB of GDDR5 clocked at 4500 MHz while the other version comes equipped with 2GB of GDDR3 clocked at 1800 MHz.

For comparison, the HD 7750 comes with 512 stream processors clocked at 800 MHz.

Both Sapphire 7730 graphics cards come with the same dual slot, single fan cooler. Also, both cards support one HDMI, one DVI, and one VGA video output. The cards measure 168 x 104 x 33mm and have a 47W TDP.

Sapphire has not yet announced US pricing or availability, but various sites around the web report that the cards will each cost approximately 70 Euros. That works out to about $91 USD. Unfortunately, that price will likely be hard to justify considering users can pick up a noticeably faster HD 7750 for around that same price. Users building a new system looking for similar GPU specs to the HD 7730 may also wish to look into building a system around AMD’s APUs and skip needing a dedicated card altogether.

Returning home on Monday, I was greeted by several (slightly wet) boxes from Asus.  Happily, the rainstorm that made these boxes a bit damp did not last long, and the wetness was only superficial.  The contents were perfectly fine.  I was pleased by this, but not particularly pleased with FedEx for leaving them in a spot where they got wet.  All complaints aside, I was obviously ecstatic to get the boxes.

Quite the lineup.  The new packaging is sharp looking and clearly defines the contents.

Inside these boxes are some of the latest and greatest video cards from Asus.  Having just finished up a budget roundup, I had the bandwidth available to tackle a much more complex task.  Asus sent four cards for our testing procedures, and I intend to go over them with a fine toothed comb.

The smallest of the bunch is the new GTX 670 DC Mini.  Asus did some serious custom work to not only get the card as small as it is, but also to redesign the power delivery system so that the chip only requires a single 8 pin PCI-E power connection.  Most GTX 670 boards require 2 x 6 pin connectors which would come out to be around 225 watts delivered, but a single 8 pin would give around 175 watts total.  This is skirting the edge of the official draw for the GTX 670, but with the GK104 chip being as mature as it is, there is some extra leeway involved.  The cooler is quite compact and apparently pretty quiet.  This is aimed at the small form factor crowd who do not want/need a overly large card, but still require a lot of performance.  While the GTX 700 series is now hitting the streets, there is still a market for this particular card.  Oh, and it is also overclocked for good measure!

asus_jd_02.jpg

We see a nice progression from big to little.  It is amazing how small the GTX 670 DC Mini is compared to the rest, and it will be quite interesting to see how it compares to the GTX 760 in testing.

The second card is the newly released GTX 760 DCII OC.  This is again based on the tried and true GK104 chip, but has several units disabled.  It has 1152 CUDA cores, but retains the same number of ROPS as the fully enabled chips.  It also features the full 256 bit memory bus running at 6 Gbps.  It has plenty of bandwidth to provide the card in most circumstances considering the amount of functional units enabled.  The cooler is one of the new DirectCU II designs and is a nice upgrade in both functionality and looks from the previous DCII models.  It is a smaller card than one would expect, but that comes from the need to simplify the card and not overbuild it like the higher priced 770 and 780 cards.  As I have mentioned before, I really like the budget and midrange cards.  This should be a really fascinating card to test.

The next card is a bit of an odd bird.  The GTX 770 DCII OC is essentially a slightly higher clocked GTX 680 from yesteryear.  One of the big changes is that this particular model foregoes the triple slot cooler of the previous generation and implements a dual slot cooler that is quite heavy and with a good fin density.  It features six pin and eight pin power connections so it has some legs for overclocking.  The back plate is there for stability and protection, and it gives the board a very nice, solid feel.  Asus added two LEDs by the power connections which show if the card is receiving power or not.  This is nice, as the fans on this card are very silent in most situations.  Nobody wants to unplug a video card that is powered up.  It retains the previous generation DCII styling, but the cooler performance is certainly nothing to sneeze at.  It also is less expensive than the previous GTX 680, but is faster.

asus_jd_03.jpg

All of the cards sport dual DVI, DisplayPort, and HDMI outputs.  Both DVI ports are dual-link, but only one is DVI-I which can also output a VGA signal with the proper adapter.

Finally we have the big daddy of the GTX 700 series.  The 780 DCII OC is pretty much a monster card that exceeds every other offering out there, except the $1K GTX Titan.  It is a slightly cut down chip as compared to the mighty Titan, but it still packs in 2304 CUDA cores.  It retains the 384 bit memory bus and runs at a brisk 6 Gbps for a whopping 288.4 GB/sec of bandwidth.  The core is overclocked to a base of 889 MHz and boosts up to 941 MHz.  The cooler on this is massive.  It features a brand new fan design for the front unit which apparently can really move the air and do so quietly.  Oddly enough, this fan made its debut appearance on the aforementioned GTX 670 DC Mini.  The PCB on the GTX 780 DCII OC is non-reference.  It features a new power delivery system that should keep this board humming when overclocked.  Asus has done their usual magic in pairing the design with high quality components which should ensure a long lifespan for this pretty expensive board.

I do like the protective plates on the backs of the bigger cards, but the rear portion of the two smaller cards are interesting as well.  We will delve more into the "Direct Power" functionality in the full review.

I am already well into testing these units and hope to have the full roundup late next week.  These are really neat cards and any consumer looking to buy a new one should certainly check out the review once it is complete.

Asus has gone past the "Superpipe" stage with the GTX 780.  That is a 10 mm heatpipe we are seeing.  All of the DCII series coolers are robust, and even the DC Mini can dissipate a lot of heat.

Gigabyte Launching Factory Overclocked GTX 760 4GB WindForce OC Graphics Card

Subject: Graphics Cards | July 9, 2013 - 04:45 AM |
Tagged: windforce 450w, gtx 760, gigabyte, factory overclocked

Gigabyte is reportedly launching a new GTX 760 graphics card with 4GB of GDDR5 memory. It will be paired with the company’s WindForce 450W cooler and uses the same PCB as its Gigabyte GTX 770 sibling.

The upcoming Gigabyte GTX 760 4GB WindForce OC is model number GV-N760OC-4GD. As the name suggests, the card comes with a decent factory overclock on the GPU. The card uses NVIDIA’s GTX 760 GPU with 1,152 CUDA cores, 96 TMUs, and 32 ROPs within 6 SMX units. Gigabyte has overclocked the GPU to 1085 MHz base and 1150 MHz boost. For comparison, the reference GTX 760 is has a base clockspeed of 980 MHz and a boost clockspeed of 1033 MHz. Memory on the Gigabyte GTX 4GB WindForce OC remains the same as the stock design, at 6GHz, there is just more of it at 4GB total versus the stock 2GB of GDDR5.

The factory overclocked card features an eight-phase VRM and the company’s WindForce 3X 450W cooler. The dual slot, triple fan cooler has three 80mm fans cooling two aluminum fin stacks that connect to the copper baseplate via two 8mm and four 6mm heatpipes. It is rated to cool up to 450W TDPs. Because this factory overclocked graphics card is based on the same PCB Gigabyte used for its GTX 770, it requires a single 6-pin and a single 8-pin PCI-E power connector. This setup should provide ample power to push voltage and get higher overclocks, the specific GPU permitting.

There is no pricing or availability information yet, but expect it to be around $270 since its 2GB sibling has an MSRP of $260. Additional photos of the new graphics card can be found over at Tech Power Up.

Tagged: R7730, msi, graphics card, GCN, 7730

If rumors hold true, consumers may be greeted with a new AMD Radeon graphics card today, in the form of a Graphics Core Next (GCN) based HD 7730. According to the leak by Videocardz, MSI will be launching a new card based on this budget GPU called the R7730-1GD5V1. It will use a shrouded fan and heatsink cooler with the company's propeller blade fan technology. Afterburner support and solid capacitors are also features of the MSI card that is rumored to use this new GPU chip. Video ouptuts include one DVI, one HDMI, and one DisplayPort connector.

The HD 7730 GPU itself is based on the same basic Cape Verde chip as the existing HD 7750 and HD 7770 GPUs. However, the HD 7730 has fewer stream processors. Specifically, the 7730 will use 384 stream processors clocked at 800 MHz. It will be paired with 1GB of GDDR5 memory on a 128-bit bus, with the memory clocked at 4.5 GHz. For comparison, the HD 7750 features 512 stream processors clocked at 800 MHz along with 1GB of GDDR5 at 4.5GHz.

This new chip will not be as fast as the similarly-clocked HD 7750, but it will also be cheaper and use less power as it is able to get all of its power from the PCI-E bus (no PCI-E power cable from the PSU required).

The MSI HD 7730 graphics card is rumored to launch sometime today for 70 Euros, or about $90 USD. (At least we will not have long to wait to see if the rumors are true!)

AMD may discontinue Radeon HD 7990

Subject: General Tech, Graphics Cards | July 4, 2013 - 06:02 PM |
Tagged: radeon hd 7990, frame rating, amd, 7990

Editor's Update (Ryan): After the long holiday I finally got around to asking AMD for an official response to this rumor.  AMD says simply:

"Plain and simple: AMD has not EOL'd the world's fastest graphics card, the AMD Radeon HD 7990."

Obviously the company is steadfast that the report from WCCFTech is incorrect so I eagerly await the new driver due by July 31st for improved frame pacing and multi-GPU performance!

END UPDATE

WCCFTech caught wind, via Overclockers.Ru, of a Radeon HD 7990 cancellation rumor. The flagship card, codenamed after the Mediterranean island, "Malta", contains two Graphics Core Next (GCN) GPUs in Crossfire. Before the canonical AMD design, certain third-party add-in-board (AIB) partners created their own designs with the 7990 moniker with a pair of 7970 GPUs as its foundation. The first official 7990s launched in April 2013.

But, it did not have the best reception.

Never Settle, get it before it settles.

The two main issues regarding 7990 adoption are, according to WCCFTech, micro-stuttering with Crossfire setups and the better dollar value of paired 7970s. The 7990 comes in at the thousand dollar ($1000 USD) price point despite being, for all intents and purposes, nearly identical to a pair of separate 7970 cards. While the 7990 has access to a superior "Never Settle" bundle when compared to twin 7970s, with the addition of a Deux Ex: Human Revolution license, it would be difficult to consider that as an excuse for the $200-$300 USD price gap.

Cost aside, this would be a really odd time to cancel the 7990. The product was launched just a few months ago, despite similar price concerns, only to be allegedly killed right before the driver that makes it worth its weight? If true, either AMD decided to annul their "mistake", or we will get some interesting news when the frame pacing driver finally gets released.

While pure speculation, my immediate reflex would be that AMD had some problem during the development of their frame pacing driver. The initial results presented by Ryan showed a great improvement, but what about a pair of 7990 cards? The way in which they, allegedly, are killing off the 7990 would suggest something abrupt came up.

Hopefully, for AMD, that was not the case.

Squeezing out every last bit of performance from the GTX 760

Subject: Graphics Cards | July 4, 2013 - 01:09 PM |
Tagged: MSI N760 TF 2GD5/OC, gtx 760, overclocking

The MSI N760 might come with a factory overclock but that doesn't mean it is at its maximum potential straight out of the box.  With the help of MSI's own Afterburner tool [H]ard|OCP undertook the project of maximizing the overclock on this GTX 760 by upping the power available to the card to 145%.  They maxed out at a base clock of 1160MHz and boost clock of 1225MHz and were even more please to see the card actually running at 1280MHz under load.  With that increased core speed and memory upped to 6.4GHz the effect on performance was notable and pushed this card beyond the performance of the competitors.

"We take the new MSI N760 TF 2GD5/OC video card and overclock it to its highest potential with MSI Afterburner. We don't stop there, we also overclock all the comparison cards to their highest potential, and see if the GTX 760 can still hold its own. We also compare performance with the Radeon HD 7950."
