For those of you worried that GDC would sneak by without any new information for NVIDIA's GeForce fans, Jen-Hsun Huang surprised everyone by showing up at the Epic Games' keynote with Tim Sweeny to hijack it.
The result: the first showing of the upcoming GeForce TITAN X based on the upcoming Maxwell GM200 GPU.
JHH stated that it would have a 12GB frame buffer and was built using 8 billion transistors! There wasn't much more information than that, but I was promised that the details would be revealed sooner rather than later.
Any guesses on performance or price?
Jen-Hsun signs the world's first TITAN X for Tim Sweeney.
Kite Demo running on TITAN X
UPDATE: I ran into the TITAN X again at the NVIDIA booth and was able to confirm a couple more things. First, the GPU will only require a 6+8-pin power connections, indicating that NVIDIA is still pushing power efficiency with GM200.
Also, as you would expect, the TITAN X will support 3-way and 4-way SLI, or at very least has the SLI bridges to support it.

They said it couldn't be done, but where there are higher density chips there's always a way. Today EVGA and Inno3D have both announced new versions of GTX 960 graphics cards with 4GB of GDDR5 memory, placing the cards in a more favorable mid-range position depending on the launch pricing.
EVGA's new 4GB NVIDIA GTX 960 SuperSC
Along with the expanded memory capacity EVGA's card features their ACX 2.0+ cooler, which promises low noise and better cooling. The SuperSC is joined by a standard ACX and the higher-clocked FTW variant, which pushes Base/Boost clocks to 1304/1367MHz out of the box.
Inno3D's press release provides fewer details, and the company appears to be launching a single new model featuring 4GB of memory which looks like a variant of their existing GTX 960 OC card.
The existing Inno3D GTX 960 OC card
The current 2GB version of the GTX 960 can be found starting at $199, so expect these expanded versions to include a price bump. The GTX 960, with only 1024 CUDA cores (half the count of a GTX 980) and a 128-bit memory interface, has been a very good performer nonetheless with much better numbers than last year's GTX 760, and is very competitive with AMD's R9 280/285. (It's a great overclocker, too.) The AMD/NVIDIA debate rages on, and NVIDIA's partners adding another 4GB offering to the mix will certainly add to the conversation, particularly as an upcoming 4GB version of the GTX 960 was originally said to be unlikely.

So apparently NVIDIA and a single AIB partner, Gigabyte, are facing a class action lawsuit because of the GeForce GTX 970 4GB controversy. I am not sure why they singled out Gigabyte, but I guess that is the way things go in the legal world. Unlucky for them, and seemingly lucky for the rest.
For those who are unaware, the controversy is based on NVIDIA claiming that the GeForce GTX 970 has 4GB of RAM, 64 ROPs, and 2048 KB of L2 Cache. In actuality, it has 56 ROPs and 1792KB of L2 Cache. The main talking point is that the RAM is segmented into two partitions, one that is 3.5GB and another that is 0.5GB. All 4GB are present on the card though, and accessible (unlike the disable L2 Cache and ROPs). Then again, I cannot see an instance in that class action lawsuit's exhibits which claim an incorrect number of ROPs or amount of L2 Cache.
Again, the benchmarks that you saw when the GeForce GTX 970 launched are still valid. Since the issue came up, Ryan has also tried various configurations of games in single- and multi-GPU systems to find conditions that would make the issue appear.

Update 2: Outside sources have confirmed to PC Perspective that this driver contains DirectX 12 as well as WDDM 2.0. They also claim that Intel and AMD have DirectX 12 drivers available through Windows Update as well. After enabling iGPU graphics on my i7-4790K, the Intel HD 4600 received a driver update, which also reports as WDDM 2.0 in DXDIAG. I do not have a compatible AMD GPU to test against (just a couple of old Windows 7 laptops) but the source is probably right and some AMD GPUs will be updated to DX12 too.
So it turns out that if your motherboard dies during a Windows Update reboot, then you are going to be spending several hours reinstalling software and patches, but that is not important. What is interesting is the installed version number for NVIDIA's GeForce Drivers when Windows Update was finished with its patching: 349.65. These are not available on NVIDIA's website, and the Driver Model reports WDDM 2.0.
It looks like Microsoft pushed out NVIDIA's DirectX 12 drivers through Windows Update. Update 1 Pt. 1: The "Runtime" reporting 11.0 is confusing though, perhaps this is just DX11 with WDDM 2.0?
I am hearing online that these drivers support the GeForce 600 series and later GPUs, and that there are later, non-public drivers available (such as 349.72 whose release notes were leaked online). NVIDIA has already announced that DirectX 12 will be supported on GeForce 400-series and later graphics cards, so Fermi drivers will be coming at some point. For now, it's apparently Kepler-and-later, though.
So with OS support and, now, released graphics drivers, all that we are waiting on is software and an SDK (plus any NDAs that may still be in effect). With Game Developers Conference (GDC 2015) coming up in a little over a week, I expect that we will get each of these very soon.
Update 1 Pt. 2: I should note that the release notes for 349.72 specifically mention DirectX 12. As mentioned above, is possible that 349.65 contains just WDDM 2.0 and not DX12, but it contains at least WDDM 2.0.

One of the perennial firms that measures GPU market share, Jon Peddie Research, has come out with a report on Q4 of 2014 this weekend and the results are eye opening. According to the data, NVIDIA and AMD each took dramatic swings from Q4 of 2013 to Q4 of 2014.
|Q4 2014||Q3 2014||Q4 2013||Year-to-year Change|
Data source: Jon Peddie Research
Here is the JPR commentary to start us out:
JPR's AIB Report tracks computer add-in graphics boards, which carry discrete graphics chips. AIBs used in desktop PCs, workstations, servers, and other devices such as scientific instruments. They are sold directly to customers as aftermarket products, or are factory installed. In all cases, AIBs represent the higher end of the graphics industry using discrete chips and private high-speed memory, as compared to the integrated GPUs in CPUs that share slower system memory.
The news was encouraging and seasonally understandable, quarter-to-quarter, the market decreased -0.68% (compared to the desktop PC market, which decreased 3.53%).
On a year-to-year basis, we found that total AIB shipments during the quarter fell -17.52% , which is more than desktop PCs, which fell -0.72%.
However, in spite of the overall decline, somewhat due to tablets and embedded graphics, the PC gaming momentum continues to build and is the bright spot in the AIB market.
NVIDIA's Maxwell GPU
The overall PC desktop market increased quarter-to-quarter including double-attach-the adding of a second (or third) AIB to a system with integrated processor graphics-and to a lesser extent, dual AIBs in performance desktop machines using either AMD's Crossfire or Nvidia's SLI technology.
The attach rate of AIBs to desktop PCs has declined from a high of 63% in Q1 2008 to 36% this quarter.
The year to year change that JPR is reporting is substantial and shows a 20+ point change in market share in favor of NVIDIA over AMD. According to this data, AMD's market share has now dropped from 35% at the end of 2013 to just 24% at the end of 2014. Meanwhile, NVIDIA continues to truck forward, going from 64.9% at the end of 2013 to 76% at the end of 2014.
The Radeon R9 285 release didn't have the impact AMD had hoped
Clearly the release of NVIDIA's Maxwell GPUs, the GeForce GTX 750 Ti, GTX 970 and GTX 980 have impacted the market even more than we initially expected. In recent weeks the GTX 970 has been getting a lot of negative press with the memory issue and I will be curious to see what effect this has on sales in the near future. But the 12 month swing that you see in the table above is the likely cause for the sudden departure of John Byrne, Collette LaForce and Raj Naik.
AMD has good products, even better pricing and a team of PR and marketing folks that are talented and aggressive. So how can the company recover from this? Products, people; new products. Will the rumors circling around the Radeon R9 390X develop into such a product?
Hopefully 2015 will provide it.

It looks like some online retailers are offering up either partial refunds or full refunds (with return) for those users that complain about the implications of the GeForce GTX 970 memory issue. On January 25th NVIDIA came clean about the true memory architecture of the GTX 970 which included changes to specifications around L2 cache and ROP count in addition to the division of the 4GB of memory into two distinct memory pools. Some users have complained about performance issues in heavy memory-depedent gaming scenarios even though my own testing has been less than conclusive.
Initially there was a demand for a recall or some kind of compensation from NVIDIA regarding the issue but that has fallen flat. What appears to be working (for some people) is going to the retailer directly. A thread on reddit.com's Hardware sub-reddit shows quite a few users were able to convince Amazon to issue 20-30% price refunds for their trouble. Even Newegg has been spotted offering either a full refund with return after the typical return window or a 20% credit through gift cards.
To be fair, some users are seeing their requests denied:
"After going back and forth for the past hour I manage to escalated my partial refund to a supervisor who promptly declined it."
"Are you serious? NewEgg told me to go complain to the vendor."
So, while we can debate the necessity or vadidity of these types of full or partial refunds from a moral ground, the truth is that this is happening. I'm very curious to hear what NVIDIA's internal thinking is on this matter and if it will impact relationships between NVIDIA, it's add-in card partners and the online retailers themselves. Who ends up paying the final costs is still up in the air I would bet.

ASUS returns to the mini-ITX friendly form-factor with the GTX 960 Mini (officially named GTX960-MOC-2GD5 for maximum convenience), their newest NVIDIA GeForce GTX 960 graphics card.
Other than the smaller size to allow compatibility with a wider array of small enclosures, the GTX 960 Mini also features an overclocked core and promises "20% cooler and vastly quieter" performance from its custom heatsink and CoolTech fan. Here's a quick rundown of key specs:
- 1190 MHz Base Clock / 1253 MHz Boost Clock
- 1024 CUDA cores
- 2GB 128-bit GDDR5 @ 7010 MHz
- 3x DisplayPort, 1x HDMI 2.0, 1x DVI output
No word on the pricing or availability of the card just yet. The other mini-ITX version of the GTX 960 on the market from Gigabyte has been selling for $199.99, so expect this to run somewhere between $200-$220 at launch.
ASUS has reused this image from the GTX 970 Mini launch, and so have I
The product page is up on the ASUS website so availability seems imminent.

Update: Whoops! The title originally said "374.52", when it should be "347.52". My mistake. Thanks "Suddenly" in the comments!
Two things from NVIDIA this week, a new driver and a new game for the NVIDIA GRID. The new driver aligns with the release of Evolve, which came out on Tuesday from the original creators of Left4Dead. The graphics vendor also claims that it will help Assassin's Creed: Unity, Battlefield 4, Dragon Age: Inquisition, The Crew, and War Thunder. Several SLi profiles were also added for Alone in the Dark: Illumination, Black Desert, Dying Light, H1Z1, Heroes of the Storm, Saint's Row: Gat out of Hell, Total War: Attila, and Triad Wars.
On the same day, NVIDIA released Brothers: A Tale of Two Sons on GRID, bringing the number of available games up to 37. This game came out in August 2013 and received a lot of critical praise. Its control style is unique, using dual-thumbstick gamepads to simultaneously control both characters. More importantly, despite being short, the game is said to have an excellent story, even achieving Game of the Year (2013) for TotalBiscuit based on its narrative, which is not something that he praises often.
I'd comment on the game, but I've yet to get the time to play it. Apparently it is only a couple hours long, so maybe I can fit it in somewhere.
Also, they apparently are now calling this “#SHIELDTuesday” rather than “#GRIDTuesday”. I assume this rebranding is because people may not know that GRID exists, but they would certainly know if they purchased an Android-based gaming device for a couple hundred dollars or more. We could read into this and make some assumptions about GRID adoption rates versus SHIELD purchases, or even purchases of the hardware itself versus their projections, but it would be pure speculation.
Both announcements were made available on Tuesday, for their respective products.
A baker's dozen of GTX 960
Back on the launch day of the GeForce GTX 960, we hosted NVIDIA's Tom Petersen for a live stream. During the event, NVIDIA and its partners provided ten GTX 960 cards for our live viewers to win which we handed out through about an hour and a half. An interesting idea was proposed during the event - what would happen if we tried to overclock all of the product NVIDIA had brought along to see what the distribution of results looked like? After notifying all the winners of their prizes and asking for permission from each, we started the arduous process of testing and overclocking a total of 13 (10 prizes plus our 3 retail units already in the office) different GTX 960 cards.
Hopefully we will be able to provide a solid base of knowledge for buyers of the GTX 960 that we don't normally have the opportunity to offer: what is the range of overclocking you can expect and what is the average or median result. I think you will find the data interesting.
The 13 Contenders
Our collection of thirteen GTX 960 cards includes a handful from ASUS, EVGA and MSI. The ASUS models are all STRIX models, the EVGA cards are of the SSC variety, and the MSI cards include a single Gaming model and three 100ME. (The only difference between the Gaming and 100ME MSI cards is the color of the cooler.)
To be fair to the prize winners, I actually assigned each of them a specific graphics card before opening them up and testing them. I didn't want to be accused of favoritism by giving the best overclockers to the best readers!
Battlefield 4 Results
At the end of my first Frame Rating evaluation of the GTX 970 after the discovery of the memory architecture issue, I proposed the idea that SLI testing would need to be done to come to a more concrete conclusion on the entire debate. It seems that our readers and the community at large agreed with us in this instance, repeatedly asking for those results in the comments of the story. After spending the better part of a full day running and re-running SLI results on a pair of GeForce GTX 970 and GTX 980 cards, we have the answers you're looking for.
Today's story is going to be short on details and long on data, so if you want the full back story on what is going on why we are taking a specific look at the GTX 970 in this capacity, read here:
- Part 1: NVIDIA issues initial statement
- Part 2: Full GTX 970 memory architecture disclosed
- Part 3: Frame Rating: GTX 970 vs GTX 980
- Part 4: Frame Rating: GTX 970 SLI vs GTX 980 SLI (what you are reading now)
Okay, are we good now? Let's dive into the first set of results in Battlefield 4.
Battlefield 4 Results
Just as I did with the first GTX 970 performance testing article, I tested Battlefield 4 at 3840x2160 (4K) and utilized the game's ability to linearly scale resolution to help me increase GPU memory allocation. In the game settings you can change that scaling option by a percentage: I went from 110% to 150% in 10% increments, increasing the load on the GPU with each step.
Memory allocation between the two SLI configurations was similar, but not as perfectly aligned with each other as we saw with our single GPU testing.
In a couple of cases, at 120% and 130% scaling, the GTX 970 cards in SLI are actually each using more memory than the GTX 980 cards. That difference is only ~100MB but that delta was not present at all in the single GPU testing.
