To quote from Ars Technica's review of the M1 by Jim Salter [0]:
> Although it's extremely difficult to get accurate Apples-to-non-Apples benchmarks on this new architecture, I feel confident in saying that this truly is a world-leading design—you can get faster raw CPU performance, but only on power-is-no-object desktop or server CPUs. Similarly, you can beat the M1's GPU with high-end Nvidia or Radeon desktop cards—but only at a massive disparity in power, physical size, and heat.
...So, given that, and assuming that Apple will attempt to compete with them, I think it likely that they will, at the very least, be able to match them on even footing, when freed from the constraints of size, heat, and power that are relevant to notebook chips.
