Explain please. What does the M1 do to IO loads?

[1_player]

Nothing. Compute speed isn't that important if you're waiting on IO is GP's point.

[boomlinde]

In that case it's a confusing point, given GGP calls this nothingness "the real innovation of the M1". GP is asking what the innovation is.

[harperlee]

It’s clearer if for M1 you read “the new architecture promoted by Apple around their M1 processor”.

[kllrnohj]

What new architecture? Other than the addition of a neural unit, it's an identical architecture to every other APU from the last decade?

[boomlinde]

It would be more clear if someone answered the question.

[K0balt]

On die memory and storage. No bottlenecks, very little latency.

[matthewmacleod]

Important to clarify this every time it comes up: there is no on-die memory on the M1. It is normal, everyday, DDR4 memory which is located near to the processor. It's actually quite high latency at ~100ns.

Indeed and I was quite surprised by this as it's actually higher latency than you'd get on AMD or Intel's chips.
