Nvidia Volta GV100 Comes In SXM2 Form Factor, Four Stacks Of HBM2 Add Up To 16 GB
Nvidia Volta may not be due till next year but we have some details regarding the Nvidia Volta GV100 chips. The Nvidia Volta GV100 features the SXM2 form factor and features four stacks of HBM2 memory which adds up to 16 GB in total, which means 4 GB per stack.
The huge 815mm2 Volta die has 21 billion transistors and is built using the 12nm FFN process by TSMC. Nvidia Volta GV100 is being shipped with 80 activated SMs this translates to 5,120 CUDA cores. It is important to note that the design has been made with 84 SM to maximize yields. 4 SMs are a counter measure of any defects in the manufacturing process.
The Nvidia Volta GV100 die size surpasses that of the GP100 by 33%, which is very impressive. 16 inductors and voltage regulators can be found on the borders of the GPU. The TDP of the chip is around 300W. While Nvidia does provide reference cooling options, most of the customers use custom cooling instead. These include both air and liquid cooling.
