To be fair idle power is really important for a lot of use cases.
In a compute focused cloud environment you might be able to have most of your hardware pegged by compute most of the time, but outside of that CPUs spend most of their time either very far under 100% capacity, or totally idle.
In order to actually calculate real efficiency gains you'd probably have to measure power usage under various scenarios though, not just whatever weird math they did here.
- throwawaylinux 5y agoThat's not really being fair, because the metric is presented to look like traditional perf/watt. And idle is not so important in supercomputers and cloud compute nodes which get optimized to keep them busy at all costs. But even in cases where it is important, averaging between the two might be reasonable but multiplying the loaded efficiency with the idle efficiency increase is ludicrous. A meaningless unit. I can't see any possible charitable explanation for this stupidity. MBAs and marketing department run amok.
- p1necone 5y agoYep 100% agree with you - see my last sentence. Just trying to clarify that the issue here isn't that idle power consumption isn't important, it's the nonsense math.
