I wouldn't say Geekbench is a good representative of real world continuous performance as the test last not long enough, as M1 Max scores way below most desktop CPU's on Cinebench R23 and that is not even mentioning Alder Lake, still being comfortably above H series CPUs though ??
I wouldn't say they has something to prove on all-in-one segment. An iMac with M1 Max inside would easily become the quietest and one of the most powerful all-in-one computers while packing a 120 Hz 5K display.
They can easily rival tower PC setups with the newly designed compact Mac Pro (or a higher Mac Mini or both with different configurations), claiming they achieve similar or higher performance in a much smaller chassis (like mini-ITX size) and power envelope. All they need to do is to provide lower priced Mac Pro configurations. ??
This post should be pinned in every discussion about M1 chips.
