I wonder how much lower it would be if data centers strictly ran on ARM cpus. Sure there are plenty other components and factors that come into play but it would be interesting to look at such a graph nonetheless.

Not saying switching to ARM CPUs in servers would be bad but it's all of the other shit in a server that's using a significant amount of power. Even if an ARM CPU is more efficient per unit of computation a server still needs lots of fast RAM, various peripheral controllers, and storage. Replacing the CPU would likely reduce system power usage by several percent but not cut it in half.
- halayli 5y agoAgreed. I wouldn't expect a 50% difference. Cloud services offer powerful GPUs, and other capabilities that can consume a lot more than a typical Intel xeon level cpu. It would be interesting to see a breakdown of power consumption in current data centers.
- bombcar 5y agoThe move from spinning rust to SSDs everywhere has probably reduced power consumption noticeably (though it’s likely just been sucked up by the cpu).
