Psst. AMD fans. Don't tell "Team Green" but Linus decided to take four R9 290X graphics cards and configure them in Quad Crossfire formation. They did not seem to have too much difficulty setting it up, although they did have trouble with throttling and setting up Crossfire profiles. When they finally were able to test it, they got a 3D Mark Fire Strike Extreme score of 14979.
Psst. NVIDIA fans. Don't tell "Team Red" but Linus decided to take four GeForce Titan Black graphics cards and configure them in Quad SLI formation. He had a bit of a difficult time setting up the machine at first, requiring a reshuffle of the cards (how would reordering PCIe slots for identical cards do anything?) and a few driver crashes, but it worked. Eventually, they got a 3D Mark Fire Strike Extreme score of around 13,300 (give or take a couple hundred).

Tagged: leak, nvidia, GM204, GTX 980, GTX 980M, GTX 970, GTX 970M
Please keep in mind that this information has been assembled via research done by WCCF Tech and Videocardz off of 3DMark entries of unreleased GPUs; we won't get the official numbers until the middle of this month. That said, rumours and guesswork about new hardware are a favourite past time of our readers so here is the information we've seen so far about the upcoming GM204 chip from NVIDIA. On the desktop side is the GeForce GTX 980 and GeForce GTX 970 which should both have 4GB of GDDR5 on a 256-bit bus with GPU clock speeds ranging from 1127 to 1190 MHz. The performance that was shown on 3DMark has the GTX 980 beating the 780 Ti and R9 290X and the GTX 970 performing similarly to the plain GTX 780 and falling behind the 290X. SLI scaling looks rather attractive with a pair of GTX 980 coming within a hair of the performance of the R9 295X2.
On the mobile side things look bleak for AMD, the GTX 980M and GTX 970M surpass the current GTX 880M which in turn benchmarks far better than AMD's M290X chip. Again the scaling in SLI systems will be impressive assuming that the leaks that you can see indepth here are accurate. It won't be too much longer before we know one way or the other so you might want to keep your finger off of the Buy Button for a short while.

I was originally intending to test this with benchmarks but, after a little while, I realized that Ivy Bridge was not supported. This graphics driver starts and ends with Haswell. While I cannot verify their claims, Intel advertises up to 30% more performance in some OpenCL tasks and a 10% increase in games like Batman: Arkham City and Sleeping Dogs. They even claim double performance out of League of Legends at 1366x768.
Intel is giving gamers a "free lunch".
The driver also tunes Conservative Morphological Anti-Aliasing (CMAA). They claim it looks better than MLAA and FXAA, "without performance impact" (their whitepaper from March showed a ~1-to-1.5 millisecond cost on Intel HD 5000). Intel recommends disabling it after exiting games to prevent it from blurring other applications, and they automatically disable it in Windows, Internet Explorer, Chrome, Firefox, and Windows 8.1 Photo.
Adaptive Rendering Control was also added in this driver. This limits redrawing identical frames by comparing the ones it does draw with previously drawn ones, and adjusts the frame rate accordingly. This is most useful for games like Angry Birds, Minesweeper, and Bejeweled LIVE. It is disabled when not on battery power, or when the driver is set to "Maximum Performance".
A few days with some magic monitors
Last month friend of the site and technology enthusiast Tom Petersen, who apparently does SOMETHING at NVIDIA, stopped by our offices to talk about G-Sync technology. A variable refresh rate feature added to new monitors with custom NVIDIA hardware, G-Sync is a technology that has been frequently discussed on PC Perspective.
The first monitor to ship with G-Sync is the ASUS ROG Swift PG278Q - a fantastic 2560x1440 27-in monitor with a 144 Hz maximum refresh rate. I wrote a glowing review of the display here recently with the only real negative to it being a high price tag: $799. But when Tom stopped out to talk about the G-Sync retail release, he happened to leave a set of three of these new displays for us to mess with in a G-Sync Surround configuration. Yummy.
So what exactly is the current experience of using a triple G-Sync monitor setup if you were lucky enough to pick up a set? The truth is that the G-Sync portion of the equation works great but that game support for Surround (or Eyefinity for that matter) is still somewhat cumbersome.
In this quick impressions article I'll walk through the setup and configuration of the system and tell you about my time playing seven different PC titles in G-Sync Surround.

Tagged: amd, R9, r9 295x2, price cut
While not fully in effect yet, AMD is cutting $500 off of the R9 295X2 price tag to $999 USD. Currently, there are two models available on Newegg USA at the reduced price, and one at Amazon for $1200. We expect to see other SKUs reduce soon, as well. This puts the water-cooled R9 295X2 just below the cost of two air-cooled R9 290X graphics cards.
If you were interested in this card, now might be the time (if one of the reduced units are available).

Matrox, along with S3, develop GPU ASICs for use with desktop add-in boards, alongside AMD and NVIDIA. Last year, they sold less than 7000 units in their quarter according to my math (rounding to 0.0% market share implies < 0.05% of total market, which was 7000 units that quarter). Today, Matrox Graphics Inc. announce that they will use an AMD GPU on their upcoming product line.
While they do not mention a specific processor, they note that "the selected AMD GPU" will be manufactured at a 28nm process with 1.5 billion transistors. It will support DirectX 11.2, OpenGL 4.4, and OpenCL 1.2. It will have a 128-bit memory bus.
Basically, it kind-of has to be Cape Verde XT (or XT GL) unless it is a new, unannounced GPU.
If it is Cape Verde XT, it would have about 1.0 to 1.2 TFLOPs of single precision performance (depending on the chosen clock rate). Whatever clock rate is chosen, the chip contains 640 shader processors. It was first released in February 2012 with the Radeon HD 7770 GHz Edition. Again, this is assuming that AMD will not release a GPU refresh for that category.
Matrox will provide their PowerDesk software to configure multiple monitors. It will work alongside AMD's professional graphics drivers. It is a sad that to see a GPU ASIC manufacturer throw in the towel, at least temporarily, but hopefully they can use AMD's technology to remain in the business with competitive products. Who knows: maybe they will make a return when future graphics APIs reduce the burden of driver and product development?
Tonga GPU Features
On December 22, 2011, AMD launched the first 28nm GPU based on an architecture called GCN on the code name Tahiti silicon. That was the release of the Radeon HD 7970 and it was the beginning of an incredibly long adventure for PC enthusiasts and gamers. We eventually saw the HD 7970 GHz Edition and the R9 280/280X releases, all based on essentially identical silicon, keeping a spot in the market for nearly 3 years. Today AMD is launching the Tonga GPU and Radeon R9 285, a new piece of silicon that shares many traits of Tahiti but adds support for some additional features.
Replacing the Radeon R9 280 in the current product stack, the R9 285 will step in at $249, essentially the same price. Buyers will be treated to an updated feature set though including options that were only previously available on the R9 290 and R9 290X (and R7 260X). These include TrueAudio, FreeSync, XDMA CrossFire and PowerTune.
Many people have been calling this architecture GCN 1.1 though AMD internally doesn't have a moniker for it. The move from Tahiti, to Hawaii and now to Tonga, reveals a new design philosophy from AMD, one of smaller and more gradual steps forward as opposed to sudden, massive improvements in specifications. Whether this change was self-imposed or a result of the slowing of process technology advancement is really a matter of opinion.

Tagged: pny, gtx 780, gtx 780 ti, Customized OC, factory overclocked
PNY is not as heavily marketed as some GPU resellers in North America but that doesn't mean they are not hard at work designing custom cards. Hardware Canucks tried out the Customized OC GTX 780 and 780 Ti recently with the factory overclock as well as pushing the cards to the limit by manual overclocking. Using EVGA's Precision overclocking tools they pushed the GTX 780 to 1120MHz Core, 6684MHz RAM and the Ti to an impressive 1162MHz Core, 7800MHz RAM. Read on to see how effective the custom cooler proved to be as it is also a major part of the Customized series.
"PNY's latest Customized series will be rolling through their GTX 780 and GTX 780 Ti lineups, bringing high end cooling and increased performance."

Tagged: radeon, r9 285, R9, amd, 285
Today during AMD's live stream event celebrating 30 years of graphics and gaming, the company spent a bit of time announcing and teasing a new graphics card, the Radeon R9 285X and R9 285. Likely based on the Tonga GPU die, the specifications haven't been confirmed but most believe that the chip will feature 2048 stream processors, 128 texture units, 32 ROPs and a 256-bit memory bus.
In a move to help donate to the Child's Play charity, AMD currently has an AMD Radeon R9 285 on Ebay. It lists an ASUS built Strix-style cooled retail card, with 2GB of memory being the only specification that is visible on the box.
The R9 285X and R9 285 will replace the R9 280X and R9 280 more than likely and we should see these shipping and available in very early September.
UPDATE: AMD showed specifications of the Radeon R9 285 during the live stream.
For those of you with eyes as bad as mine, here are the finer points:
- 1,792 Stream Processors
- 918 MHz GPU Clock
- 3.29 TFLOPS peak performance
- 112 Texture units
- 32 ROPs
- 2GB GDDR5
- 256-bit memory bus
- 5.5 GHz memory clock
- 2x 6-pin power connectors
- 190 watt TDP
- $249 MSRP
- Release date: September 2nd
These Tonga GPU specifications are VERY similar to that of the R9 280: 1792 stream units, 112 texture units, etc. However, the R9 280 had a wider memory bus (384-bit) but runs at 500 MHz lower effective frequency. Clock speeds on Tonga look like they are just slightly lower as well. Maybe most interesting is the frame buffer size drop from 3GB to 2GB.
That's all we have for now, but I expect we'll have our samples in very soon and expect a full review shortly!
UPDATE 2: Apparently AMD hasn't said anything about the Radeon R9 285X, so for the time being, that still falls under the "rumor" category. I'm sure we'll know more soon though.

Earlier today we had NVIDIA's Tom Petersen in studio to discuss the retail availability of G-Sync monitors as well as to get hands on with a set of three ASUS ROG Swift PG278Q monitors running in G-Sync Surround! It was truly an impressive sight and if you missed any of it, you can catch the entire replay right here.
Even if seeing the ASUS PG278Q monitor again doesn't interest you (we have our full review of the monitor right here), you won't want to miss the very detailed Q&A that occurs, answering quite a few reader questions about the technology. Covered items include:
- Potential added latency of G-Sync
- Future needs for multiple DP connections on GeForce GPUs
- Upcoming 4K and 1080p G-Sync panels
- Can G-Sync Surround work through an MST Hub?
- What happens to G-Sync when the frame rate exceeds the panel refresh rate? Or drops below minimum refresh rate?
- What does that memory on the G-Sync module actually do??
- A demo of the new NVIDIA SHIELD Tablet capabilities
- A whole lot more!
Another big thank you to NVIDIA and Tom Petersen for stopping out our way and for spending the time to discuss these topics with our readers. Stay tuned here at PC Perspective as we will have more thoughts and reactions to G-Sync Surround very soon!!
