I come here with a question about undervolting the processor to ~95w

I wonder which of these cpu generations can reach 95w without significant performance loss

I would like to ask you to provide the values and in which games they were tested

ps: I’m writing about 95w because I have an i5-9600K, so the higher power consumption (250w) is terrifying for me *including the graphics card power consumption

    Among the classic desktop versions the higher the gen and model, the better power efficiency at low wattages, so an i9-14900K would give you the highest performance at a 95W power limit.

    Additionally with undervolting you’d get a bit more performance out of it at the same power consumption

    How are you planning to cool it and what are you going to use it for?

    I just tried to cap a 14700k to 253 watts. I was able to get the average below 200 watts (closer to 180) but I observed brief spikes in aida64 and with my ups monitoring to 325 watts even with pl1/pl2 set to 125 and most post tech off. (MCE, TVB, ABT off and some other tuning)

    I’d say it’s difficult to prevent high usage spikes with 14th gen based on this.

    my 13600k reach 125watts (vcore 1.077v) without any issue/ performance loss,.

    and this 125-130watts is max powerdraw in cbr23,. if i play games its take 30-55watts ,. some cases 75watts (like cyberpunk),.

    full performance with 125-130watts - 24200 cbr23 score;
    reduced performance with 95watts - 22800 cbr23 score https://imgur.com/a/owNYMrO (i use both hwinfo and hwmonitor :) );

    this 95watts is power limit over 125watts undervolt; so its not affect gaming performance and gaming power draws.

    Terrified of power consumption?

    Sounds like you need to talk to a shrink more than R/intel

    Pretty sure this is what killed my 13900k just warning
