- jeffbee 4y agoYes but either you need your computer to work and therefore you are willing to accept the fact that energy=work, or you don't need the computer to do anything in which case it will just sit there silently drawing ~1W.
- kamranjon 4y agoOr you choose a CPU that does more work per unit of energy because you value silence
- kitsunesoba 4y agoI really wish perf per watt would catch on as the metric to chase for enthusiast/prosumer-oriented desktop CPUs. Or be advertised at all, really.
- jeffbee 4y agoPerf per watt isn’t interesting to users who want the job finished. Work done per joule is extremely interesting but Intel is near the top of the game on that metric. Many CPUs that are viewed as low power are not energy efficient. On an energy basis the “performance” cores in an Intel CPU are more efficient than the “efficiency” cores.
- doublepg23 4y agoThey already are though. The currently shipping Intel and AMD chips perform similarly at 65W.
- snuxoll 4y agoTDP and actual power draw are two VERY different things. Intel and AMD both will plaster 95W or 125W or 160W TDPs on chips that will draw well over 250W when boosting as long as your cooling allows for it.
- TylerE 4y agoYour second case is rather...optimistic given the amount of background work any modern OS does. My i9 desktop will start to spin the fans up with light web browsing. To be precise, even at true zero load, an i9-10850k (what I've got) draws 25-30w. Any sort of load at all and it gets to 60+w. A gaming type load is well over 125w.
- jeffbee 4y agoMaybe you should choose a better operating system?
- BirAdam 4y agoNo. That's just the modern web. If a person needs to use the modern web, he/she needs to use a browser. If he/she needs to use a browser, it is almost always going to be Chrome (or something built on Chrome). Chrome is heavy on Linux, BSD, and macOS as are many of the pages it loads. The web can spin up fans on Intel, AMD, and ARM when I am running NetBSD, Slackware, or Intel Clear Linux.
- LawTalkingGuy 4y agoPut a CPU limit on the process. I do it for gaming to keep Dwarf Fortress from pinning my CPU even in the menus.
- jeffbee 4y agoIf you are measuring that correctly it means that your operating system or something about your platform is utterly broken. `turbostat` and `powertop` on my i7-13700K indicate that it is currently, at "true zero load", drawing 1.1W
- TylerE 4y agoNot my measures… measurements by people who run hardware websites. i9 is much hotter than i7, especially the high end ones. When I bought the cpu the only thing higher (without getting into server grade stuff) was the 10900k which was basically unobtanium.
- doublepg23 4y agoThat’s more related to fan choice (Noctua is the pro move) but it’s still going to be idling most of the time.
- grogenaut 4y agoIn a closed room heat isn't down to fan, that heat may not be in the case but it's not getting pumped out of my room quickly. I'm basically running a 900 watt heater whenever I'm doing hangouts or gaming
- doublepg23 4y agoBut the new chips are already shipping with an “ECO mode” for small-form factor computers. That just makes it easy though, undervolting was already popular. The alternative is shipping a power constrained for…no gain? Letting the cpu boost this high is only a boon for people who want it and is an imagined negative.
- grogenaut 4y agoWindows nor call of duty seem to care not about those settings. Happy to run at full blast all the time. And then there's the 3090.
- TillE 4y agoI have an NH-D15, it's still extremely audible in a quiet room.
