Donning the leather jacket he goes very few places without, NVIDIA CEO Jen-Hsun Huang showed up at an AI meet-up at Stanford this evening to show, for the very first time, a graphics card based on a never before seen Pascal GP102 GPU.

Rehashing an old name, NVIDIA will call this new graphics card the Titan X. You know, like the "new iPad" this is the "new TitanX." Here is the data we know about thus far:
|Titan X (Pascal)||GTX 1080||GTX 980 Ti||TITAN X||GTX 980||R9 Fury X||R9 Fury||R9 Nano||R9 390X|

Note: everything with a ? on is educated guesses on our part.
Obviously there is a lot for us to still learn about this new GPU and graphics card, including why in the WORLD it is still being called Titan X, rather than...just about anything else. That aside, GP102 will feature 40% more CUDA cores than the GP104 at slightly lower clock speeds. The rated 11 TFLOPS of single precision compute of the new Titan X is 34% better than that of the GeForce GTX 1080 and I would expect gaming performance to scale in line with that difference.
The new Titan X will feature 12GB of GDDR5X memory, not HBM as the GP100 chip has, so this is clearly a new chip with a new memory interface. NVIDIA claims it will have 480 GB/s of bandwidth, and I am guessing is built on a 384-bit memory controller interface running at the same 10 Gbps as the GTX 1080. It's truly amazing hardware.
What will you be asked to pay? $1200, going on sale on August 2nd, and only on NVIDIA.com, at least for now. Considering the prices of GeForce GTX 1080 cards with such limited availability, the $1200 price tag MIGHT NOT seem so insane. That's higher than the $999 starting price of the Titan X based on Maxwell in March of 2015 - the claims that NVIDIA is artificially raising prices of cards in each segment will continue, it seems.
I am curious about the TDP on the new Titan X -
will it hit the 250 watt mark of the previous version? Yes, apparently it will it that 250 watt TDP - specs above updated. Does this also mean we'll see a GeForce GTX 1080 Ti that falls between the GTX 1080 and this new Titan X? Maybe, but we are likely looking at an $899 or higher SEP - so get those wallets ready.
That's it for now; we'll have a briefing where we can get more details soon, and hopefully a review ready for you on August 2nd when the cards go on sale!
