If these M processors were made to work in other OS environments that would be correct. But they are literally engineered for Unix(Ios) use and applications. None Apple Software its still up in the air as these chips are still new relatively speaking and non apple/adobe FP encoding software is still not tested compared to PC counterpart. So no according to these leaked benchmarks from literally couple weeks ago those numbers they throw at you are specific numbers for specific tasks which is what the M1/M1X chips were made for.
Intel/amd MAKE cpu's that are varied for their purpose and use case. Which is why in these leaked charts M1X stacks well in Cinebench, and Video encode benchmarks within their own iOS environment.
But if you compare them to things outside of apple they still dont kill the playing field like you state.
Single core tests:
Multicore tests:
And thats against a AMD apu NOT their any of their flagship Ryzen or Threadripper.
If you configure a lenovo or MSI wa Workstation with a combo of the latest Intel Xeon or Ryzen 9 with a nvidia or Radeon render card the performance is different depending on applications. AND since M1/X chips are only on apple's platform its hard to say how they stack on more Windows/Business based applications.
