You could pretty easily compare Intel 4 RWC and TSMC N5 Apple M1 with the data David Huang's perf/watt testing provided us.

The M1 scores ~20% higher at 11 watts package power vs RWC.
Comparing just core+cache power:

It's even worse.
Area comparisons between the M1 core and RWC, since they are on similar nodes, would look something like this:
RWC + core private cache: 5.33mm2
M1 + core private cache: 2.28mm2
Ok, but that's not really fair considering the M1 still has a sizable L2 shared with other cores that doesn't get counted. Also, AMX seems to be separated from the core?
We can do this a couple ways:
M1 but with shared L2, L2 logic control and AMX area split up equally per core: 3.889mm2
Or we can just compare an entire quad core P-core complex:
RWC quad core complex: 30.588mm2 (I think I was being a bit generous towards Intel with this calc)
RWC quad core complex without L3: 21.32mm2
M1 quad core complex: 15.555mm2
Ok, now we can also look at total perf:

Just looks like a worse core from every perspective tbh. Perf, power, and area.
