    Are we sure the supposed die shot isn't some sort of funky marketing image render? If not and despite the GPU being obviously a specialized unit for upcoming automotive needs, the transistor count and die area for the GPU sounds massive for 512 SPs.

    Looks real to me. https://i.imgur.com/7KfJCpI.jpg GPU is 90mm²

    Holy mother of smokes.......that could mean =/>2.3b transistors.

    It's an automotive oriented product. You don't know what kind of functional safety features it has included, even in the GPU. It can blow up transistor size dramatically.

    Yeah a serious amount of safety being developed around the product; from the safety sensors generally with other cameras to analysing the driver with Drive IX.
    That last point is pretty critical IMO when a lot of talk is around passing control back to driver or even taking control (fits more with professional transport world) such as a lorry driver falls asleep/illness/etc and this can be expanded to many diverse transport modes.

    Wouldn't that put the Volta SM units at a transistor count rather close to Pascal's?

    Going by the presentation.
    Volta GV100 has 21bn transistors for its FP32/FP64/Int32 CUDA cores/640 Tensor cores at 815mm2.
    Xavier is missing the FP64 cores, while having just 512 FP32 CUDA cores/INT32 cores (either 4 or 8 SM), the whole SoC has 9.1bn transistors at 350mm2.
    Tensor structure may be subtly different for Xavier as well.

    Regarding relationship to Pascal.
    V100 has 42.3% more transistors than P100, and it has a similar increase in core count so it would not necessarily stand out when both have comparable core counts.
    P100 with 15.3 bn transistors and 3584 FP32 CUDA cores/half FP64.
    V100 with 21.1bn transistors and 5120 FP32 CUDA cores/half FP64/640 Tensor cores
