Y en otro lado he leído esto:
Switch is special in that it supports two kinds of FLOPS. PS4 Pro can do this as well. The normal kind is FP32. For that, Switch 153.6/192 GFLOPS in handheld mode and 384 GFLOPS docked. The other kind, FP16, doubles those numbers. The 1 TFLOPS figure comes from a Tegra X1 (the chip that Switch uses) at its full 1GHz GPU clock in FP16.
By the way, raw numbers aren't everything. Switch uses a newer and more efficient GPU architecture than even PS4 and Xbox One, so even though the handheld numbers look lower than PS360U, it's more power than all of them in all modes.
