Nvidia Pascal GP100 Die Shot Photo

Nvidia Pascal GP100 Die Shot Photo

Over at the Hot Chips symposium Nvidia has been sharing a thing or two with media. Quite interesting is a new photo series of the GP100. Now do not confuse GP100 with the GP102 that is housed in the Nvidia Titan X (Pascal).

The GP100 is the GPU that houses HBM2 is referred to as BIG Pascal. Ryan over at Anandtech posted an actual die shot of the graphics processor, and man that thing is just HUGE as it is 610mm2. Big Pascal made on TSMC's 16 nanometer silicon fab process. 

Ya'll ready? here it is:

 
GP100 in particular comes with stacked HBM2 (16GB in four stacks). The Pascal based GPU driving the unit holds 15 Billion transistors which is roughly double that of the current biggest Maxwell chip. Gp100 is huge at 610mm^2. The prognosis performance (according to Nvidia) is 5.3TFLOPS using 64-bit floating-point numbers and is rated at 10.6TFLOPS using 32-bit and 21.2TFLOPS using 16-bit. P100 has 4MB of L2 cache and 14MB of shared memory for just the register file. The following table provides a high-level comparison of Tesla P100 specifications compared to previous-generation Tesla GPU accelerators, I added the GP100 as a fully enabled product:

GPU Die Size 551 mm² 601 mm² 610 mm² 610 mm²
Manufacturing Process 28-nm 28-nm 16-nm 16-nm

As the block diagram now shows, the GP100 features six graphics processing clusters (GPCs). Just look at the diagram and count that each GPC holds 10 streaming multiprocessors (SMs) and then each SM has 64 CUDA cores and four texture units. Do the math and you'll reach 640 shader processors per GPC and 3840 shader cores with 240 texture units in total. 6 (GPC) x (10x64) = 3840 Shader processor units in total. Some additional photos can be spotted below including an actual photo of the GP100 silicon. Click the thumbnails to enlarge.

There is 2 tesla version of pascal, one cut down and one full, the info are on the dedicated website (the cut down have less hbm2 memory too btw).

I'm confused is this supposed to replace the current titan, is it the 1080ti, or both and anyone that already bought a titan has been screwed just like very first titan lol

The only people that actually need a Titan, and have a Titan, have more than enough money for another Titan.
