Alder Lake-S leaks

[humbug]

Cinebench R20 scores leaked. Seems to be equivalent to 5900X in the 125-150W range

CPU-Z scores also leaked.

12600K is pretty good, but then its a 10 core CPU, i don't know what that wattage is about but surely the 12600K is not 241 Watts?

Comparison, Its 5% faster....

The 12600k's Intel published slides says it has 228w PL2, so 228w is probably what the 12600k was pulling during Lenovo's test.

But you're right in that the data doesn't look right. If PL2 is 228 then why did the 12600k only gain 10% performance while the 12700k and 12900k gained over 30% from 241w.

Intel could be doing something to hold down the 12600k from competing with its other chips? Or Lenovo it's self

The other thing that is interesting is that there is a 1400point gap between the 12700 and 12900.

If I assume they running at roughly the same clocks, then the 1400 point gap is attributed to the 4 extra little cores the 12900k has.

Which then means 2800 of the 12900k's 10000 is from the little cores and 7200 from the big cores - so even without any little cores, a simple 8 core, 16 thread alder lake (at PL2 241w) would have easily beaten a 5800x.

This means I can also forecast future performance to some degree, so a 13900k raptor lake with its 8 big cores and 16 little cores would score about 13k in this benchmark assuming clocks and IPC is exactly the same.

Don't forget this is a 5600X competitor yet looks to be 40% faster in MT and between 20-25% faster in ST while also being cheaper in the KF model.

Hopefully we will see some benches soon ..

I heard someone say that the 12400 was meant be coming before Christmas is this no longer the case? Would really like to build something that uses less juice.

I believe they said end of q1 2022 for any further chip launches, but who knows.

Where do you get that from?
Turbo power for 12900K is 241W
for 12700K is 190W
for 12600K is 150W

and base for all three is 125W.

This alignes with performance deltas you see in lenovo slide.

Ah you're right, got it off a tweaktown article
