My desktop system is a 24-core Zen 2. The M1 shouldn't be faster, and I'm certain the difference is almost purely a matter of software, but in reality the M1 certainly feels a lot faster.

Yes, the desktop has higher throughput. Of course it does. But that doesn't mean I don't feel a fraction of a second's lag whenever I do basically anything, and on the M1 that just... doesn't exist.

FWIW in a benchmark of a lua parser my friend is writing my M1 beat my 5950X Ryzen by a factor of 2x. According to him the L1/L2 cache makes the difference.

So it's not just a matter of feel.

On the other hand, my i7 16 inch MacBook Pro consists of purely lag. Half of the time it’ll be the ‘kernel process’ so I don’t even have a clue what’s causing it.
