Intel solutions always seem to have better idle consumption. Maybe this has changed, I'm still playing with older equipment.

- KaiserPro 4y agoFrom the stuff I have access too physically (xeons(well gold cpus) and thread rippers) the intel stuff is much cooler until you really rag it, where as the threadrippers are just plain warm. This isn't scientific, so I might be comparing big 64 thread monsters to smaller intel jobbies.
- selectodude 4y agoMy Zen3 still pulls >25W at idle which is an absolute embarrassment.
- duffyjp 4y agoIs that a from-the-wall number or just the CPU?
- sgtnoodle 4y agoMy 5950x desktop pulls like 60W from the wall at idle in linux.
- GrayShade 4y agoDamn. I'll have to test again, but mine idles around 120 W IIRC.
- sgtnoodle 4y agoMy UPS reads 150W when my monitors are both powered on.
- ridgered4 4y agoIt doesn't help that the x570 chipset uses like twice the idle power of the x470 it replaced.
- sgtnoodle 4y agoI have a b550 chipset. It's got Gigabyte's high end VRM circuit, though.
- eBombzor 4y agoOne major drawback of the chiplet arch.
- mrguyorama 4y agoI found that having steam open caused my ryzen 5 3600 to go from 3 watts idle to multiple tens of watts. Chromium under the hood is so stupid.
- jeffbee 4y agoIf anything Intel has become better with each newer generation. My 12700K idled at < 3W package power. My 13700K pulls even less. They have a lot of good stuff going on like not enabling the L3 cache if the CPU in only briefly awake, or dynamically resizing L3 if they can get away with it.
- thekombustor 4y agoFellow 12700k owner, I am very impressed with the idle power consumption. Mine reports idle at ~7W, which is pretty close to my laptop's R7 4750U. Came from an R5 2600, which I'm almost positive idled higher. While the full-core power consumption is quite excessive, I think Intel overall does a good job of efficiency under idle/light load.
- jeffbee 4y agoIf you object to the K-series CPU's ability to draw current, you have the option to use the linux tool `powercap-set` to limit it to 65W, 95W, or whatever arbitrary limit you think is best. Intel RAPL accepts its parameter down to the microwatt.
