How powerful is the Apple M1 processor? Because Apple only provides some charts and how fast the application is, it is difficult to fully estimate for the time being. However, CPU Money released relevant data today for your reference. Since the M1 is an 8 Core, I found the Intel Xeon W-3223 (8 Core) running score for Mac Pro to compare, which can highlight the performance gap.
Mac Pro Intel Xeon W-3223 (8 Core) Geekbench 5 results
Geekbench 5 Single Core scored 1634 points, which is faster than AMD Ryzen 9 5950X and Intel Core i7-1185G7. The Intel Xeon W-3223 (8 Core) Single Core score of Mac Pro is 1069 points, because the M1 has already won in single core performance.
As for Geekbench 5 Multi Core, the score reached 7220 points, which is similar to AMD Epyc 7401P and Intel Xeon E5-2687W v3. It is much higher than Apple's A14 processor (6-core). If the Mac Pro Intel Xeon W-3223 (8 Core) Multi Core score is 7667, it is only 6% lower.
