And here it is playing fc6 maxed out at 25w with a 3090

THANK you sir. You are the first person to dare test, I applaud you.ran it a 2nd time and it got higher:
score 11927
6 gc cores can match that score at 45-50w. Here is my run at 55
Soldato
More than 15k
Can get more if i reset my memory to defaults but im bored of retraining afterwards
what sort of score would it get at 115w with all cores unlocked and not restricted to 6?
Soldato
Thats what i keep saying, the p cores are phenomenal and probably going to beat zen 4 in efficiency as well. Its the ecores that are terrible cause intel decided to clock them way outside their efficiency point.
Soldato
Well not sure, cant test it now since i left my house. Considering it gets 16200 at 65 watts, id assume 18-19k, maybe more. Ill test when I get back
Ps1. Oh wait, you mean with ecores as well? Probably around 23k
well thats settled then. unless anyone with a 5950x can run some benches too at different wattage points it looks to be a clear win for intel in efficiency and if the above figures are correct with the 12900k getting around 23k at 115w then even i too doubt zen4 can match that.
Soldato
With ecores on im sure zen 3 can match it, cause as I've been saying ecores are pretty bad at efficiency. 8p + 8e is less efficient than 16 zen 3 cores (unless you drop to less than 80w total). But 8p vs 8zen 3 cores, its a slaughter.
Ive seen 5950x getting around 24 to 25k at 120 ppt, so yeah, 16 zen 3 cores > 8+8

AMD's Ryzen 7 5800X3D Draws Less than Half as Much Power than the Intel Core i9-12900KS and Yet Faster in Gaming Workloads | Hardware Times
AMD’s Ryzen 7 5800X3D is now available for purchase at retailers across the world. Pairing 64MB of 3D stacked L3 cache (overall 96MB) with the mature Zen 3 CCD results in the fastest gaming processor which beats not only Intel’s Core i9-12900K but the recently launched $749 i9-12900KS as well...

Isn't this what we should be looking at in terms of efficiency. I don't play CB-R23. I play games and so what watts it uses when gaming is relative between CPUs.

Right so you have posted one thing about one game but stock out the box performance for multiple games is as linked etc. Being efficient out the box and running games as per the stock settings should be the base. Running something at 25watt is irrelevant. I am home tonight so can put my 5950x at 25watt for FC6 and my 6900xt and see what I get if you want but I don't have a 3090 and other factors would be involved unless you happen to have an AMD CPU to normal that is worthless info.
No I am not wrong, you are, this is the problem. You cant see what's there right in front of you and are blindly making claims on "efficiency" but don't really understand what the industry means by efficiency. I tried to give you the benefit of the doubt and explain in plain English what "efficiency" is all about but you just don't seem to get it....
Intel doesn't have products there because of efficiency... Simple as that. Everybody before me is likely trying to explain the same thing but you are blind to anything but your "benchmark" when efficiency isn't only about speed.
Just to add - Please don't bother replying. I can't be bothered with the argument.
Soldato
I do find it really odd when you get people who are normal home users sat behind a keyboard, arguing with people who work in the industries where it is your job to know about all of this. Literal hands on everyday use with things they'll never get a sniff at, but nope because they bought a CPU in box, and can watch YouTube they are right, so don't be arguing!
Did you seen the link I posted in the EPYC thread btw Vince, with the leaked Genoa benchmarks?
I did - Man it looks an absolute beast! But that new socket means I can't just buy one
I might tap up HP again and see if I can have a play!

TPU already did similar testing using a 12900K.
Granted this is in full system power but the only differences are CPU, Mobo and Ram of which CPU and Mobo are inevitably going to differ so it is not an unfair comparison IMO.
The 100W PL1/PL2 limited 12900K gets 86.157 points / watt.
The 125W PL1/PL2 limited 12900K gets 93.495 points / watt.
The 190W PL1/PL2 limited 12900K gets 110.925 points / watt.
The stock 5800X gets 90.0457 points / watt.
The stock 5950X gets 144.2 points / watt.
In the 5700X review it scored 13474pts @ 126W for a score of 106.937 points / watt.
So as @Vince very correctly points out there are settings you can use where the 12900K is more efficient than than the 5800X but this kind of tuning for the 12900K can be done on the 5800X via certain settings and you can easily increase the points/watt by setting it to 65W which will get it closer to the 5700X score.
I can also tell you that my 5800X3D with a -30 all core offset scores ~15100 while using less power than stock.
It would be interesting to see if the 5950X with power limits removed would increase in efficiency as I know it can score > 31,000 points but not sure what the system powerdraw would be. If it came in under 215 or less it would beat the stock 5950X 144.2 but I don't think it would.
