Intel 10th Gen Core "Comet Lake" Desktop Processor CPUID, TDP, and cTDP Revealed

[btarunr]

Internal documents of Intel's 10th generation Core "Comet Lake" processor family, leaked by momomo_us, reveal the CPUID, TDP, and configurable-TDP values of the various desktop SKUs. Intel broadly classifies Comet Lake by core-count and companion iGPU tier. The 10-core Comet Lake die ships with 125 W, 65 W, and 35 W TDP, for the K/KF, locked, and T-SKUs, respectively.

For the desktop Comet Lake-S, there are only two iGPU tiers, GT2 (iGPU present in UHD 630 flavor), or completely disabled (denoted as GT0). The charts detailing the non-Turbo clock speeds reveal that the presence or absence of iGPU has no impact on TDP, cTDP, or CPU frequencies. The "Comet Lake" 10-core + GT2 silicon is listed with a CPUID of A0655h, while the 6-core + GT2 and 4-core + GT2 variants share the A0653h CPUID.

14nm in 2020 is a really dire state of affairs for Intel. These are based off 2015's Skylake, higher frequencies, massive power draw and heat, and two more cores at the top.

But surely not it says 125 watts max

I can't believe the Tdp and Ctdp which in themselves are total nonesense equals a news piece on it's own , it's Brazen Bs that I ,if I were intel would have buried in the footnotes.

So is that 125w just sitting there, and 275w loaded?

As usual, it's 125W for base frequencies. Turbo Boost can draw up to 250W, if available and thermally possible.

And as usual that number appears on nothing a typical customer might see.

You can turn off Turbo Boost with ThrottleStop to stick within 125w, but typical customer will not use ThrottleStop.

More information about the "hot lake". The power draw does give something to think about. 250W turbo and if you OC, I don't even wanna know. This one CPU draws more power than an entire decent graphics card.

which usually dictated by the motherboard vendors, I think they will push it indefinitely and will only be limited by the thermals, so the motherboard will look good on benchmarks.

Is that a bad thing, while there's untapped potential in the silicone?
And if you worry about thermals, a locked CPU coupled with an H chipset will keep in the 65W ballpark anyway.

Few buy something that states upto 5ghz then do anything that stops that working, at least till the dust bunnies wreak their vengeance ,then they will all be here trying to get throttle stop to stop it down clocking and ruining fornite not the opposite ,often.

It's very disingenuous. Borderline dubious, well it's worse than that IMHO.

A lot of the stuff in the tech sheets appears on "nothing a typical customer might see". But the tech sheets are still available

See the Op's tech sheet's posted above, Even the tech wise have to dig way too deep.

You would think Pl2 was a dirty word.

 

[Metroid]

125w idle and full load 500w, that I can agree.

And yet here we are, all aware and discussing the issue

 

[Turmania]

I will wait for the reviews, i do not think it will be worser then their 9th gen parts in power consumption as people here make it out to be. I will specifically look into i5 10600k and compare that with i5 9600k and ryzen5 3600x.

I5 10600 compares to I7 8700K, $100 cheaper, +100Mhz more. And now with thinned die, cooler.

Of course people make it out to be worse, look at 3700X 140 watts vs 157 watt, 9900K. It's laughable a 14 watts difference.

9900K drops to 4.4Ghz to fit in 95 watts +14 watts more power than 3700X 4.2Ghz, if it were 4.2Ghz vs 4.2Ghz it would be 140 watts vs 140 watts.

The only reason they are pushing 125+ watts now is because of the 4.9Ghz mark.

Obviously when voltage is raised power is raised to the power of 3, for 10% overclock, 1.1*1.1*1.1 you get 33% more power.

If AMD could do this their TDP will also jump by the same 33%, that is all.

But that additional power draw on the Ryzen systems comes from two things:
1. Power hog Infinity Fabric which has been fixed in Renoir;
2. X570 chipset raised power draw.

Those figures are not CPU to CPU straight comparisons.

 

[ppn]

renoir has to drop to 100 total system power to even make sense, because I believe I7 10700 +motherboard with the right VRMs can do 120 with some undervolting 4.200 @ 1 volt.

The fact that I think it will be much more than 125 watts is more due to the Z490 VRM array on most boards being much closer to Threadripper or X299 in terms of how they are built. There is no way you would put that much power delivery on a board if you don't have to. Some boards have 12+ 90 Amp power stages. Just look at a difference between the VRMs on Z490 vs Z390.

And yes, my less informed friends ask me before building a new PC.

why is it all or nothing with your type.

who said everyone cares, your saying, sorry implying no one cares, it is obviously somewhere between, just like not everyone has a helpful friend like you.

if no one really cared the likes of tesla wouldn't be going well, perspective, there is more than one.

Well, it's not all or nothing.
People imply that because Intel doesn't print all fine detail on the box, they're somehow misleading customers.
When I point out the info is actually available, you cry "but average Joe doesn't know how to get it".
All I said is average Joe probably doesn't even care about that. They're probably not going to buy the unlocked parts anyway.

Basically it's people implying there's a problem before there's as much as a hint of a problem in the real world. Kinda annoying for me.

 

[freeagent]

Well, if your rig pulled 200 at the wall just sitting there at the desktop, you would care. Then load up the cpu with something redonkulous Like linpack xtreme and watch that 200w turn into 400w. It’s not easy to cool something like that, especially quietly. I’m talking about my old x5690 that I recently started using again. Compared to my 3770K it has no respect for the environment lol.
