NVIDIA Pascal GP104 Die Photo
Last week Nvidia announced the Tesla P100 data-center GPU and if you looked closely at the photo's you could already clearly see that big Pascal 15B transistor GPU being used. A new photo this time showing the GP104 GPU (successor to the GM204 = GTX 970/980).
According to the leak the photo shown below is the GP104 (GM204 successor) intended for Nvidia's pending high-end products, and it measures roughly 290-300mm². At the right side you can see Samsung K4G80325FB - 1.5V 8Gb 8Gbps (8000MHz) GDDR5. Word on the street is that this GPU would hold 2560 shader processors.
The rectangular die of the GP104 was measured at 15.35 mm x 19.18 mm which should house (very speculative) a transistor-count of 7.4~7.9 billion. Interesting to see is that this chip is tied towards Samsung 8-gigabit GDDR5 memory chips. These ICs run an effective speed of 8 GHz (GDDR5 and thus not GDDR5X). At 256-bit you'ld be looking at 256 GB/s of bandwidth. The shader processor core count of the GP104 could be closer to 2,560, than the 4,096 from an older report.
Earlier on it was speculated that graphics cards based on these GPUs would be called X70 and X80, the specs do not meet up even slightly though.

Word. The 950 should not get the GTX badge.
But at least they dropped the GT vs Ultra suffixes, those were a bit confusing.
It should be as it was with the 500 series. 550 and under was GT, 560 and above was GTX.
At least they're not overinflating their numbers like AMD does. 7850, 7870, 7950, 7970, 7990. Versus 650, 660, 670, 680, 690. WTF srsly. It's very confusing and even now I have to look up benchmarks every damn time I want to compare the cards.
I don't see the problem as the GTX brand has been diluted to the point of being meaningless. It used to be only the high end models were GTX, like *70 and *80 series cards. Now you have GTX 950's out the *ss. Seriously? It's a 950.

I haven't seen conclusive proof that HBM actually helps the Fury X to a tangible level. If anyone has such proof, please share it with me.
yes obviously it push to the top, but sadly for us AMD have made terrible choise of HBM1 wich is limited to 4gb...
so the perf are crippled due to lack of ramspace (and in some case even the previous gen high end do better).
now about the "GDDR5 only" drama: on pict i just see prototype or sample, if it work with GDDR5 then it work with GDDR5X too, it's pin to pin compatible (i can already smell old GPU stock with GDDR5X and a new name... lol).
and GDDR5X is clearly nice ram, and cost less than HBM2 (that will be used for high end in red and green flavor for sure).
"don't sell bear's skin before getting it first" none GPU from neither company are ready... let them come out and tested

GTX mean gaming
not only high end at 4K over 100fps
there is some that doesn't need so much power (and money lol)
the gtx950 is aimed at 1080 60fps for Moba and game like WoT etc... and it does this pretty well, and even in some top game from last year it perform really well (i was clearly impress the 1st time i pair it with I3... you get a lot for the money... i understand their success).
it is not high end GPU but clearly a GTX.

I kinda get the feeling big Pascal GP100 will be only for Tesla GPUs. Those big chips are just too expensive to sell for consumer gear. The DX-1 box costs around $130,000 with 8 of those GPUs. If you cut off around $30K for the other server components, your looking around $12,500 per GPU! I don't think we'll see anything like this chip for consumers until 16nm process is mature. I bet the chip yields are horrible right now, hence why they cost a fortune.
I bet the GP104 chip will be a different design entirely. Well still based off the GP100 but with some changes. They will probably kill all the Double Precision (DP) units, games don't really make use of that hardware. That silicon space would be much better utilized for Single Precision (SP) shader cores. Currently half of the silicon space on the GP100 is used for DP units, using that space for SP units would be a much better design for a gaming GPU.

This is such complete speculation. It all depends on the clocks too. This is more or less a shrunk 980Ti. If it hits 2GHz then it's fine.
