Anyone know if idle draw has been measured for Zen 4? Is it improved over Zen 3?
Curious if they fixed the I/O die disabling all the power saving features when not run at stock.
I'll just post this here. If you can find a 12900K doing a similar score at same power, I'll happily admit you're right.

Well, the performance in the application (score, time to complete, etc.) versus the energy consumed (in joules). Doing this for a range of power limits lets you figure out the most efficient power range for that specific task.
Say, cinebench score per joule consumed. More efficient CPUs (for...
Probably not constant, but a MT workload that is steady state, say looping cinebench performance at 65 W locked, as an example. I know a lot of "MT" tasks change between single and nT threads from start to completion.
What does it matter if it's "out of the box"? It's basically Intel setting the power limit for you before you boot the system. Power efficiency is performance at a given power consumption, and I am not convinced the 7950x will be bested there at those power ranges.
Also, Intel's "T" skus still...
Alright, I'll bite, in what way is the 13900T going to be the most efficient on planet Earth? Getting the most MT performance at that power usage I assume?
....I agreed with you. The 12600K is faster than all of Zen 3 in those tasks. But it's because of the P-cores, not the E-cores.
Only reason I say this is because that's what Biostud was asking about. What the E-cores provide. The truth is not much, they boost MT perf at the benefit of Intel's...
They asked about the E-cores, you answered with the 12600K beating the 5950x. Is this supposed to imply that E-cores are somehow responsible for this?
For the average user, doing the three things that you described: Browsing the web, office functions and gaming, all benefit from single thread...
When you consider that roughly ~100 W or so is I/O die, that means you're looking at 280 - 300 W for cores alone. With 384 threads, you're looking at ~1.5 - 1.6 W per core, or ~0.7 - 0.8 W per thread. Ball park numbers of course.
Crazy stuff.
....Am I missing something? How is the 13900K going to be competitive with the 7950x if Det0x just posted his 5950x beating it?
If anything, 7950x with DDR5 should be undisputed #1 in decompression (and likely compression as well)
Not bad for ~250 W, E cores definitely pulling more weight in that MT score. Wonder how much it can improve with a tune. I think the 12900KS can do 31K at ~ 250 W. So 13900K/KS should be able to do a decent bit better with some TLC.
Curious to see how 7950x stacks up.
