Because you didn't mark this as a question and that is a good thing.

Some new numbers from Qualcomm.

YO WE HAVE SINGLE THREAD POWER CURVES FOR THE FIRST TIME!!!!!



Also:

Does anybody have higher quality images of these slides?

ST power consumption in excess of 10W sounds concerning.
Doesn’t matter how far they *can* push it. What matters is the shape of the curve. It’s also Windows and they’ll have multiple SKUs. That 13-14W or so is at the absolute peak of their ST (aka 4.3GHz) almost certainly.

It’s a pretty steep slope overall. Looks good.

Am I missing something? Isn't these slides showing that X Elite is matching Intel Core Ultra peak while using 40% of the power (10W x 25W) in single core?

To me these slides just show that QCOM core can scale from low-end of the power curve to the high-end of the curve while outpacing Intel best at any point.

The relevant graph is versus PHX.
Right. Phoenix cores and X Elite are a very impressive showpiece, specially given that they're beating current gen competition.

But by the time QCOM product has mass availability and is on shelves, AMD will have a much more competitive line-up. Specially with STX. So it's kinda "eh".

Yes, yes, doomed Qualcomm, etc. We get it.

10W single-core power at highest part of the DVFS curve is not horrendously high for a PC core. At all.
Precisely. It’s profoundly weird to think otherwise especially for this case with their SKUs and Windows.

Even M2/3 base model power from the wall (minus display) tops up 8+W these days, if not 10, so they’re fine.

Yes that’s correct. It outdoes AMD too.

That 13W peak power is certainly higher than Apple M3
