If you’re only heavily using one of the cores, that core is free to use a lot more power, and can probably push its clock speed much higher than if this were an all-core workload. So I’d actually expect the opposite, that the ampere would be allowed to use a lot more power than the M1 (since it’s not a laptop).
- error503 4y agoAmpere's processors are more or less fixed clock, which makes sense to me in a processor designed for cloud servers. You don't really want unpredictable performance, and in a multi-tenant situation like Oracle Cloud where I ran it, you don't want customer A's workload to affect customer B's performance running on the same physical processor. With 10x the number of cores as the M1 Max and a TDP of 250W (maybe 5x? Apple doesn't publish numbers), the average power limit per core is likely significantly less, and the M1 might be able to leverage 'turbo' here for this short benchmark. Still, this is not really a meaningful benchmark, just interesting.
