They really aren't comparable. For example, standby power for Lakefield appears to be 2.5mW. Idle is probably significantly lower as well. They're targeting different use cases.
- AnthonyMouse 6y agoI can't find any figures for the standby power for Ryzen 4000 series, but standby is basically off. The standby power consumption should be negligible in both cases. It's also not obvious what that use case would be. You can put most laptops into standby and they'll run on battery like that for many weeks. What's the thing that needs more than that? It would be interesting to compare idle power consumption, but for that we'd have to know what it actually is.
- londons_explore 6y agoAlso, don't most x86 CPU's support being powered off entirely during standby? Ie. flush the caches, write the registers back to RAM, set RAM to self-refresh, and then write some config registers in some power control IC to cut the power to the CPU. Then it doesn't matter what the standby power consumption is - it simply matters how quickly it can get back into a working state from OFF.
