A TITANic roundup of GPUs

You have read Ryan's review of the $999 behemoth from NVIDIA and now you can take the opportunity to see what other reviewers think of the card.  [H]ard|OCP tested it against the GTX 980 which shares the same cooler and is every bit as long as the TITAN X.  Along the way they found a use for the 12GB of VRAM as both Watch_Dogs and Far Cry 4 used over 7GB of memory when tested at 4k resolution though the frame rates were not really playable, you will need at least two TITAN X's to pull that off.  They will be revisiting this card in the future, providing more tests for a card with incredible performance and an even more incredible price.

"The TITAN X video card has 12GB of VRAM, not 11.5GB, 50% more streaming units, 50% more texture units, and 50% more CUDA cores than the current GTX 980 flagship NVIDIA GPU. While this is not our full TITAN X review, this preview focuses on what the TITAN X delivers when directly compared to the GTX 980."

NVIDIA Announces DIGITS DevBox - 28 TFLOPS, 1300 Watts, $15k

Subject: General Tech, Graphics Cards, Shows and Expos | March 17, 2015 - 03:44 PM |

At GTC, NVIDIA announced a new device called the DIGITS DevBox:

GTC-30.jpg
        

The DIGITS DevBox is a device that data scientists can purchase and install locally. Plugged into a single electrical outlet, this modified Corsair Air 540 case equipped with quad TITAN X (reviewed here) GPUs can crank out 28 TeraFLOPS of compute power. The installed CPU is a Haswell-E 5930K, and the system is rated to draw 1300W of power. NVIDIA is building these in-house as the expected volume is low, with these units likely going to universities and small compute research firms.

Why would you want such compute power?

DIGITS is a software package available from NVIDIA. Its purpose is to act as a tool for data scientists to manipulate deep learning environments (neural networks). This package, running on a DIGITS DevBox, will give much more compute power capability to scientists who need it for their work. Getting this tech in the hands of more scientists will accelerate this technology and lead to what NVIDIA hopes will be a ‘Big Bang’ in this emerging GPU-compute-heavy field.

More from GTC is coming soon, as well as an exclusive PC Perspective Live Stream set to start in just a few minutes! Did I mention we will be giving away a Titan X???

**Update**

Ryan interviewed the lead developer of DIGITS in the video below. This offers a great explanation (and example) of what this deep learning stuff is all about:

GM200 Specifications

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.

GTC 2015: NVIDIA Roadmap Shows Pascal with 3D Memory, NVLink and Mixed Precision Compute

Tagged: pascal, nvidia, gtc 2015, GTC, geforce

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.

GTC-36.jpg

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.

GTC-38.jpg

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.

NVIDIA Quadro M6000 Leaks via Deadmau5

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 Releases GeForce GTX 960M and GTX 950M Mobile Graphics

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.

geforce-gtx-960m-3qtr.png

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.
