With the release of the GeForce GTX 980 back in September of 2014, NVIDIA took the lead in performance with single GPU graphics cards. The GTX 980 and GTX 970 were both impressive options. The GTX 970 offered better performance than the R9 290 as did the GTX 980 compared to the R9 290X; on top of that, both did so while running at lower power consumption and while including new features like DX12 feature level support, HDMI 2.0 and MFAA (multi-frame antialiasing). Because of those factors, the GTX 980 and GTX 970 were fantastic sellers, helping to push NVIDIA’s market share over 75% as of the 4th quarter of 2014.
But in the back of our mind, and in the minds of many NVIDIA fans, we knew that the company had another GPU it was holding on to: the bigger, badder version of Maxwell. The only question was going to be WHEN the company would release it and sell us a new flagship GeForce card. In most instances, this decision is based on the competitive landscape, such as when AMD might be finally updating its Radeon R9 290X Hawaii family of products with the rumored R9 390X. Perhaps NVIDIA is tired of waiting or maybe the strategy is to launch soon before Fiji GPUs make their debut. Either way, NVIDIA officially took the wraps off of the new GeForce GTX TITAN X at the Game Developers Conference two weeks ago.
At the session hosted by Epic Games’ Tim Sweeney, NVIDIA CEO Jen-Hsun Huang arrived when Tim lamented about needing more GPU horsepower for their UE4 content. In his hands he had the first TITAN X GPU and talked about only a couple of specifications: the card would have 12GB of memory and it would be based on a GPU with 8 billion transistors.
Since that day, you have likely seen picture after picture, rumor after rumor, about specifications, pricing and performance. Wait no longer: the GeForce GTX TITAN X is here. With a $999 price tag and a GPU with 3072 CUDA cores, we clearly have a new king of the court.

At the keynote of the GPU Technology Conference (GTC) today, NVIDIA CEO Jen-Hsun Huang disclosed some more updates on the roadmap for future GPU technologies.
Most of the detail was around Pascal, due in 2016, that will introduce three new features including mixed compute precision, 3D (stacked) memory, and NVLink. Mixed precision is a method of computing in FP16, allowing calculations to run much faster at lower accuracy than full single or double precision when they are not necessary. Keeping in mind that Maxwell doesn't have an implementation with full speed DP compute (today), it would seem that NVIDIA is targeting different compute tasks moving forward. Though details are short, mixed precision would likely indicate processing cores than can handle both data types.
3D memory is the ability to put memory on-die with the GPU directly to improve overall memory banwidth. The visual diagram that NVIDIA showed on stage indicated that Pascal would have 750 GB/s of bandwidth, compared to 300-350 GB/s on Maxwell today.
NVLink is a new way of connecting GPUs, improving on bandwidth by more than 5x over current implementations of PCI Express. They claim this will allow for connecting as many as 8 GPUs for deep learning performance improvements (up to 10x). What that means for gaming has yet to be discussed.
NVIDIA made some other interesting claims as well. Pascal will be more than 2x more performance per watt efficient than Maxwell, even without the three new features listed above. It will also ship (in a compute targeted product) with a 32GB memory system compared to the 12GB of memory announced on the Titan X today. Pascal will also have 4x the performance in mixed precision compute.

Sometimes information comes from the least likely of sources. Deadmau5, one of the world's biggest names in house music, posted an interesting picture to his Instagram feed a couple of days ago.
Well, that's interesting. A quick hunt on Google for the NVIDIA M6000 reveals rumors of it being a GM200-based 12GB graphics card. Sound familiar? NVIDIA recently announced the GeForce GTX TITAN X based on an identical configuration at GDC last week.
A backup of the Instagram image...in case it gets removed.
With NVIDIA's GPU Technology Conference coming up starting this Tuesday, it would appear we have more than one version of GM200 incoming.

NVIDIA has announced new GPUs to round out their 900-series mobile lineup, and the new GTX 960M and GTX 950M are based on the same GM107 core as the previous 860M/850M parts.
Both GPUs feature 640 CUDA Cores and are separated by Base clock speed, with the GTX 960M operating at 1096 MHz and GTX 950M at 914 MHz. Both have unlisted maximum Boost frequencies that will likely vary based on thermal constraints. The memory interface is the other differentiator between the GPUs, with the GTX 960M sporting dedicated GDDR5 memory, and the GTX 950M can be implemented with either DDR3 or GDDR5 memory. Both GTX 960M and 950M use the same 128-bit memory interface and support up to 4GB of memory.
As reported by multiple sources the core powering the 960M/950M is a GM107 Maxwell GPU, which means that we are essentially talking about rebadged 860M/850M products, though the unlisted Boost frequencies could potentially be higher with these parts with improved silicon on a mature 28nm process. In contrast the previously announced GTX 965M is based on a cut down Maxwell GM204 GPU, with its 1024 CUDA Cores representing half of the GPU core introduced with the GTX 980.
New notebooks featuring the GTX 960M have already been announced by NVIDIA's partners, so we will soon see if there is any performance improvement to these refreshed GM107 parts.

Manufacturers announcing 4GB versions of the GeForce GTX 960 has become a regular occurrence of late, and today MSI has announced their own 4GB GTX 960, adding a model with this higher memory capacity to their popular MSI Gaming graphics card lineup.
The GTX 960 Gaming 4GB features an overclocked core in addition to the doubled frame buffer, with 1241MHz Base, 1304MHz Boost clocks (compared to the stock GTX 960 1127MHz Base, 1178MHz Boost clocks). The card also features their proprietary Twin Frozr V (5 for non-Romans) cooler, which they claim surpasses previous generations of their Twin Frozr coolers "by a large margin", with a new design featuring their SuperSU heat pipes and a pair of 100mm Torx fans with alternating standard/dispersion fan blades.
The card is set to be shown at the Intel Extreme Masters gaming event in Poland later this week, and pricing/availability have not been announced.

The ASUS Strix Series is popular around PC Perspective thanks to the hefty factory overclocks and the quiet and efficient DirectCU II cooling. We have given away 2GB versions of the GTX 960 and Josh recently wrapped up a review of the tiny GTX 750 Ti for SFF builds.
Today ASUS announced the STRIX-GTX960-DC2OC-4GD5, a 4GB version of the Strix GTX 960 with a base clock of 165MHz higher than the default at 1291MHz and with a 1317MHz boost clock and memory clocked at 7010MHz. The DirectCU II cooling solution has proven to live up to the hype that surrounds it, indeed the cooler is whisper quiet and even under load which heavily overclocked it is much less noticeable than other solutions, especially when attached to Maxwell.
The outputs are impressive, DVI, HDMI and three DisplayPort outputs will have you gaming on a variety of monitors and it will support 4k resolutions, at reasonable graphics settings of course. Along with the card you get the familiar GPU Tweak utility for tweaking your card and for a limited time the card will come with a free one year XSplit Premium License to allow you to share your best and worst moments with the world. So far only the 2GB model is showing up at Amazon, NewEgg and B&H so you might want to hold off for a few days but it is worth noting that these cards will get you a free pre-ordered copy of Witcher 3.

Possibly the most important feature of upcoming graphics APIs, albeit the least interesting for enthusiasts, is how much easier driver development will become. So many decisions and tasks that once laid on the shoulders of AMD, Intel, NVIDIA, and the rest will now be given to game developers or made obsolete. Of course, you might think that game developers would oppose this burden, but (from what I understand) it is a weight they already bear, just when dealing with the symptoms instead of the root problem.
This also helps other hardware vendors become competitive. Imagination Technologies is definitely not new to the field. Their graphics powers the PlayStation Vita, many earlier Intel graphics processors, and the last couple of iPhones. Despite how abrupt the API came about, they have a proof of concept driver that was present at GDC. The unfinished driver was running an OpenGL ES 3.0 demo that was converted to the Vulkan API.
A screenshot of the CPU usage was also provided, which is admittedly heavily cropped and hard to read. The one on the left claims 1.2% CPU load, with a fairly flat curve, while the one on the right claims 5% and seems to waggle more. Granted, the wobble could be partially explained by differences in the time they chose to profile.
According to Tom's Hardware, source code will be released “in the near future”.

Don't get too excited about this news, but AMD tells me that its next flagship Radeon R9 graphics card is up and running at GDC, powering an Oculus-based Epic "Showdown" demo.
Inside the box...
During my meeting with AMD today I was told that inside that little PC sits the "upcoming flagship Radeon R9 graphics card" but, of course, no other information was given. The following is an estimated transcript of the event:
Ryan: Can I see it?
Ryan: I can't even take the side panel off it?
Ryan. How can I know you're telling the truth then? Can I open up the driver or anything?
Ryan: GPU-Z? Anything?
Well, I tried.
Is this the rumored R9 390X with the integrated water cooler? Is it something else completely? AMD wouldn't even let me behind the system to look for a radiator so I'm afraid that is where my speculation will end.
Hooked up to the system was a Crescent Bay Oculus headset running the well-received Epic "Showdown" demo. The experience was smooth though of course there were no indications of frame rate, etc. while it was going on. After our discussion with AMD earlier in the week about its LiquidVR SDK, AMD is clearly taking the VR transition seriously. NVIDIA's GPUs might be dominating the show-floor demos but AMD wanted to be sure it wasn't left out of the discussion.
Can I just get this Fiji card already??
