Hot Hardware published a review on the NVIDIA Unveils Beastly Tesla P100 15 Billion Transistor, 16nm FinFET GPU With HBM2 And 21 TFLOPs Performance

A quote from the article:

NVIDIA just pulled the wraps off its fastest GPU and compute engine yet: the Tesla P100. This new GPU powerhouse is based on NVIDIA's next generation Pascal architecture, which means that it's built on a 16nm FinFET process. But even with thoroughly modern FinFET process tech, the Tesla P100's die size measures 600mm2 due in part to the 15.3 billion transistors that comprise the new compute engine ? nearly twice that of Maxwell, for reference.
