Arm64 (M3) lags behind in some single core benchmarks vs Intel's high end desktop CPUs and is abysmal in multi-core benchmarks due to the limited number of cores, at least according to https://www.cpu-monkey.com.

Granted, the Intel CPU at the high end is pulling 250W+ (or was it 300W+?).

There are places for both architectures. I don't see x86 going anywhere unless Intel folds and ceases to design chips. Not sure AMD could power on alone given their current market share, though I certainly hope they could as a user of their chips in the desktop (and conversely, an M2 Air for my laptop).

I agree actually, I just wanted to set an upper-bound that nobody could really disagree with in the pro-ARM direction.

A minor quibble—high end desktop is a niche almost seemingly intentionally(?) ignored by ARM. Ampere puts out interesting server chips, and Apple puts out interesting laptop chips. What a high end desktop ARM chip? Apple’s max and ultra chips maybe, but they are pretty clearly a compromise with the fact that that market is pretty niche.

I was under the impression the M4 chip already in the iPad Pro and laptops soon to be launched this month will bring them to single core parity again.

The A18 launched with the iPhone 16 was also supposedly beating Intel single core as well.
