Comet Lake-S may require hefty CPU coolers: Core i9-10900F shown to have a 170 W PL1 (TDP) and 224 W PL2 for a 4.6 GHz all-core boost

[Redaktion]

It looks like Intel may have hit a hard limit on optimizing the power draws of the upcoming 10th gen Comet Lake-S if a recent stress test leak of the Core i9-10900F is anything to go by. The test shows that the Core i9-10900F has a PL1 of 170 W but requires a PL2 of 224 W to sustain an all-core boost of 4.6 GHz. If the numbers are true, Comet Lake-S would require hefty CPU coolers for sustained turbo performance under load.

What a disaster.

Look like it's is outclassed by 3900X.

I wouldn't really expect significantly better efficiency. Especially as Intel is struggling with vulnerabilities. Whatever improvements they make can get eaten by mitigations. If you extrapolate for the 9900KS, ten cores running at 5 GHz would make it about 213 W. For a top bin vs. 4.6 GHz @ 224 W for the lowest bin. And truth be told, I don't really care that much in a desktop with beefy cooling.

However, the 9900 has 65 W TDP. Going from 65 to 170 seems strange. I don't know what to make of that number.

It would be interesting to compare it with a 9900. That also has 4.6 GHz all core boost IIRC. And can break 230 W with the right workload (hello, AVX :-) ). As loads matter. With one "stress" test, it can be 130 W. With another, it's 230 W (same frequency). It also depends on the motherboard and setup. Some motherboards wouldn't allow you to pump 230+ W into a 9900, so it wouldn't be able to keep the boost pinned (I think it would drop under 3 GHz on a standard setup). And it can be the same story with the 10900F. I really am not expecting to see 170 W TDP on that thing. What would have to be the base clock, anyway, for it to be that high? And with stock settings and running within Intel specification, I don't think it's going to take 220+ W. Yes, on the right motherboard with the appropriate setup, you might break 250 W (extrapolation would suggest that you might approach 300, if the God of silicon allows).

it's just this crap is still sits tightly in people's heads, cuz it has been poured there heavily through billions worth of markiting BS all these years while amd had troubles catching intel

where? show me the place with these people. all media and forums bashing intel 24/7.
amd is just unable to produce and sell more than a small fraction of the market. have you heard what su said about laptops&2020? 28-30% growth or something. 10% in 2019, 13% in 2020. having superiour product.

With numbers like that, any so-called enthusiast buying one of these is getting themselves a very expensive dunce-cap.
