At first glace yeah, but that's 45W at 2.5Ghz, but TDP isn't the power rating of the CPU. That benchmark lists the Intel CPU as up to 4.9Ghz, I would say it's actual power draw was closer to the 100W mark for CPU only.
- EvgeniyZh 5y ago4.9 GHz should be single-core max freq, not applicable in multicore benchmark. All-core turbo is lower, but also AFAIK there is a limit on time it run on this freq (tau for PL2, i think around half a minute by default).
- klelatti 5y agoIs there any reason why the Intel CPU wouldn’t run at 4.9 GHz for the single core benchmark though - whilst the M1 would be limited to a much lower frequency which it can sustain for much longer?
- EvgeniyZh 5y agoI think, but I'm not 100% sure, that limits are on overall TDP, i.e., single-core workloaad can run on turbo indefinitely. Then aalso I'd assume benchmarks are much longer than any reasonable value of tau which means it integrates out (i.e., Intel performance may be higher in short-term). Edit: that is probably one of the reasons single-core gap is smaller
- klelatti 5y agoThanks - this all highlights some of the interesting trade offs in CPU design!
