Regarding 2x faster than pytorch being a condition for tinygrad to come out of alpha:

Can they/someone else give more details as to what workloads pytorch is more than 2x slower than the hardware provides? Most of the papers use standard components and I assume pytorch is already pretty performant at implementing them at 50+% of extractable performance from typical GPUs.

If they mean more esoteric stuff that requires writing custom kernels to get good performance out of the chips, then that's a different issue.
