NVIDIA Announces GeForce GTX Titan X
by Ryan Smith on March 4, 2015 1:45 PM ESTDuring today’s GDC session on Epic’s Unreal Engine, NVIDIA CEO Jen-Hsun Huang dropped in as a special guest to announce NVIDIA’s next high performance video card, the GeForce GTX Titan X.
In order to capitalize on the large audience of the Unreal session while not spoiling too much ahead of NVIDIA’s own event in 2 weeks – the NVIDIA GPU Technology Conference – NVIDIA is playing coy with details on the product, but they have released a handful of details along with a product image.

The GPU underlying GTX Titan X is 8 billion transistors, which similar to the original GTX Titan’s launch means we’re almost certainly looking at Big Maxwell. NVIDIA will be pairing it with 12GB VRAM – indicating a 384-bit memory bus – and it will once again be using NVIDIA’s excellent metal cooler and shroud, originally introduced on the original GTX Titan.
No further details are being provided at this time, and we’re expecting to hear more about it at GTC. Meanwhile Epic’s master engine programmer Tim Sweeney was gifted the first GTX Titan X card, in recognition of NVIDIA and Epic’s long development partnership and the fact that Epic guys are always looking for more powerful video cards to push the envelope on Unreal Engine 4.

That's even larger than GT200 (576 mm^2). My calculations put it around ~610 mm^2 which is gigantic.Kevin G - Wednesday, March 4, 2015 - link
My guestimation put it at 594 mm^2, pretty close. Remember that not all functional units are being increased (video decoder/encoder etc.).Still not a record holder for chip size. Intel's Tukwila Itanium 2 was 699 mm^2. At the time, the 65 nm limit was estimated around 750 mm^2 due to the optics involved.

We need to ask if the VRAM is partitioned to two 6 GB sets or three 4 GB sets or one 12 GB. Fair question. TDP and price are the only items from the table above that I'm curious about. The each Titan chip has spent too little time as the top dog for the money they're asking. It maybe makes sense as a CUDA card, but it has none of the virtualization features.It is total crap that 8 generations of GPUs need to be 28 nm. I totally understand it may not be AMD or Nvidia's fault. Too many processes are built for low power chips.
To be mentioned - the AMD R295 is now about $600 on Newegg. Don't forget it will cost $30 a month in electrical bills though.

If the number of ROPs is evenly divisible with the amount of memory, there doesn't need to be any partitioning. Its only a tool used when the numbers diverge, like 56 ROPs and 4GB.However 96 ROPs on a 384-bit bus match perfectly with 6 or 12 GB of memory. Extrapolating from the 980, it will have 12 ports with a 32-bit MC each and 8 ROPs, each hosting 128MB of memory.

I read somewhere else it was going to be a contiguous 12gb, but so far noone knows for certain.It would be a little ridiculous for them to put that much RAM on it and not be able to properly utilize it though.

lol this isn't the 970...Kutark - Sunday, March 8, 2015 - link
Desperate for what? Gaining an even larger lead on AMD?Wreckage - Wednesday, March 4, 2015 - link
I'm glad someone had new hardware to show at GDC. Now if someone could mail me 2 of these for "testing purposes".ArmedandDangerous - Wednesday, March 4, 2015 - link
First column should say Titan X and not Titan Black and then Titan Black again :Dsquatsh - Wednesday, March 4, 2015 - link
Okay so GM204 (980) has 64 rops. This has 96 (with a question mark next to it ) so thats 150%Adding a extra 50% to the other numbers from GM204 gives us:
3077 Cuda Cores
192 Texture Units
384 bit bus is 150% of 256% of the 980
This has 3 times the RAM, but it is a titan, so maybe 980ti will have 6gb (ie 150% of 980 again)
Memory clock and core clock I would expect to be the usual. 7ghz and 1ghz-ish respectively.
Oh and the 5.2 Billion transistors of the 980 * 150% would give 7.8, or close to 8 billion. So this times by 150% thing seem to fit pretty well.
(This is all from just noticing the simple 50% increase in ROPs and doing the numbers incase someone is interested, none of this is solid information).
