1. This is a slide from Intel. And they dont mention what sort of performance. Edit [1]

2. This is from witeken. A Well known Intel "supporter".

AlderLake is good, but claiming it offer more Pref / Watt than Apple's M1 Max on a node that is generation behind would require some independent testing to verify . Because all the data known so far doesn't seems to suggest this. Especially in the case of Single Core Performance.

[1] The metric used is the geometric mean of an "n-copy" SPECrate run of the C/C++ integer benchmarks in SPEC CPU 2017. You can find the M1 SPECrate 2017 results here
