That would be a disappointing increase of only quadruple the current Switch. I hope it's more of a 6-7 times increase. |
The improvements in power consumption from smaller nodes are, IPC improvements and different clock-voltage curves aside, a direct function of the physical size of their transistors.
The scaling between TSMC's 16FF and N5 is 88 x 70 nm / 51 x 28 nm ) = 4.36 times. For actual GPUs in real-world scenarios, you can see the improvement was more like ~ 3 times between a GeForce 10 and a GeForce 40:
So yeah, the overall improvement should be around that ballpark. It has to.
Mind that Ampere GPUs can also dual-issue FP32 instructions if there's no simultaneous INT32 going on. So it could claim to be a ~ 4TF console but perform closer to a PS4 than a Series S (without DLSS).
