"Apple's M1 comes out firmly on top of both the quad-core/octa-thread
i7-1185G7 and octa-core/octa-thread Ryzen 7 4700U in unlimited multicore
testing. Just for fun, we limited the Ryzen 9 5950X to eight threads only and
added it to the mix—even with only eight cores active, the 5950X easily
dominates here. But it's important to remember that only four of the M1's
eight cores are the Firestorm high-performance version... and that the 5950X
has a TDP more than three times the entire whole-system power draw of the
Mini!"

"Next up, I limited both the 5950X (as the world-leading single-threaded
x86-64 CPU) and the M1 to four threads only, and I ran the Cinebench R23 test
again. Running head-to-head with the M1's four Firestorm high-performance
cores against four of the 5950X's 16 cores, the 5950X wins with an 8.3%
performance increase."

"Although this test produced very different results from Geekbench, it does
confirm that the M1 is a world-leading processor design. Even when stacked up
against AMD's Ryzen 7 4700u, with its eight full, high-performance cores, the
M1 eked out an extremely narrow victory. That victory is well within the
margin of error... but it also demonstrates that even on the 4700U's best day,
it can't beat Apple's ARM processor in this power configuration."

"If Apple's M1 isn't the fastest single-thread—and
quad-thread—consumer-available processor on the planet, it certainly isn't
missing it by much."

"With that said, the M1 isn't magic—if a competitor can bring more cores and
threads to a massively parallel fight, it can beat the M1 by large margins.
But that competitor can only do so at serious power and thermal
discrepancies—and probably at a high manufacturing cost discrepancy as well."

To ostatnie brzmi jakby znajomo… "możemy zrobić szybsze procesory, ale będą
drogie, gorące i prądożerne". Intel jest nowym PowerPC?
