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).
