Intel Xeon W9-3495X Sets World Record, Dethrones AMD Threadripper
When Intel announced the appearance of the 4th generation Xeon-W processors, the company announced that the clock multiplier was left unlocked, available for overclockers to try and push these chips even harder. However, it was only a matter of time before we saw the top-end Xeon-W SKU take a chance at beating the world record in Cinebench R23. The Intel Xeon W9-3495X SKU is officially the world record score holder with 132,484 points in Cinebench R23. The overclocker OGS from Greece managed to push all 56 cores and 112 threads of the CPU to 5.4 GHz clock frequency using liquid nitrogen (LN2) cooling setup. Using ASUS Pro WS W790E-SAGE SE motherboard and G-SKILL Zeta R5 RAM kit, the OC record was set on March 8th.
The previous record holder of this position was AMD with its Threadripper Pro 5995WX with 64 cores and 128 threads clocked at 5.4 GHz. Not only did Xeon W9-3495X set the Cinebench R23 record, but the SKU also placed the newest record for Cinebench R20, Y-Cruncher, 3DMark CPU test, and Geekbench 3 as well.

Pffft - only because nobody has yet pushed beyond a 96-core Genoa EPYC. Threadripper is old and tired and 96C/192T EPYC Genoa doesn't exist in a platform that's open to overclocking. It would murder Sapphire Rapids in 2P configuration (already has) but the limitation is CB23's 256-core limit. A 2P Genoa server is just wasting 128 cores because Cinebench needs updating to handle faster, wider platforms....If the TDP of 420W is 56 cores at 3.3GHz (as reported), that's around 950mv on Intel7 for Golden Cove P-cores.
LN2 voltage wall for 12th/13th gen is around 1.5V
(1500/950) for the ΔP, (5.4/3.3) for the ΔF, and 420W*(ΔP^2)*ΔF=1713W
YMMV based on silicon lottery. ofc. Primo-grade W9-3495X silicon is probably more efficient than most, but the 13900KS we're comparing against for Golden Cove is already cherry-picked, top-tier silicon so I don't think my guess is going to be out by more than 20% or so. 1400W+ for sure. I wonder what PSU they were using for this run...
It's only a rough calculation but for the last 20 years of CPUs and GPUs it's nearly always been in the right ballpark.
Edit:
Oh i wrote before you finished your comment. Now it's clearer. From observing the matches.
P=IV and I=V/R. so substituting I from Ohms Law into Watt's Law gives you two V's on the top side of the equation P=V*V/R.
That's where your squared comes from for power.
I am not sure you can finish school without knowing Ohms law even when taking Music oriented Class.
wow just wow
We are hitting limit of the silicon process, some parts even refuse to shrink more. The outcome is obvious. This sport... LN ePeen contest is not a indicator for something. The tuning of the silicon efficiency is not directly related to the maximum performance under LN. It is a design plan.
I would guess around 900 to 1200W....
The customer base of Xeons care more about stability than overclocking.
This would actually be a perfuect MacPro (don't get me started lol) CPU, but I'm excited to see the Trashcan incident repeat intself...lol
