AMD Threadripper PRO 9995WX Made to Run at 5.00 GHz All-Core, Scores 186K CB Multithreaded at 947W

The 96-core/192-thread AMD Ryzen Threadripper PRO 9995WX was made to run at 5.00 GHz all-core, which no small feat considering its enormous core-count. This was pulled off by American overclocker SkywalkerAMD. The processor set a huge Cinebench R23 multithreaded score of 186800 points, but here's where it gets interesting—the processor was measured to draw a whopping 948 W. Cooling the beast is an SP5-compatible all in one liquid CPU cooler, but when faced with a thermal load of nearly 1 kW, the chip nears its T-junction max value, measuring 98 °C. The 186k points score is interestingly not the highest ever score for a 1P machine, that distinction goes to a workstation powered by a previous-generation Threadripper PRO 7995WX cooled by liquid nitrogen. Find more details in the HWBOT link below.

96 cores at near 5Ghz for reference. That's insanely efficient.

And I thought that My psu with 1kW is a lot, hmm I'm waiting to see 3 phase psu for workstation.

If it was not for the weird memory configuration the score would be better, but probably not with much, since R23 is not so sensitive to the memory

For some configs running 2 high end GPUs coupled with these CPUs even at stock speeds 1.6kW PSU will be insufficient.

Who took one Watt?

~10 Watt per Core sounds not that bad

hwinfo is not a measurement. // checking the source of the source of the source. Measurement was something uncalibrated without accuracy - hwinfo.

that is like 10 watt per core, that is not groundbreaking or something.

No it's not. 96 full cores (no half cache, half power, e-core or LP core) running ALL simultaneously with HT enabled at 5.00 GHz with power draw below 1kW. Right?
Maybe take a look at 9900X or 9950X or even 9800X3D. They consume far more per core, specifically 9950X draws 200W+ in CB2024 with default voltage.

True. But 9950X also runs at about 5GHz and has 16 cores, so... :D

The hell ... I made mistake in my previous post. 9950X eats 200-210W in CB2024 when properly cooled. It's nowhere around 10W/core.

I can only think of Terry Crews shouting "POWEEEEEEEEER" when I see those numbers (both the watts and the cbr23 points)

It's cool to think how cheap a CPU like this will be in 5 years and more efficient and at the same time much more affordable.

This damn CPU is a beast! RAW compute power, but needs a kilowatt of electricity to drive it!

This, yes!
ChomiqOnly $11k.
Only.. :laugh:

I saved this for last because I'm curious: How is this insanely efficient? A 16core 170W CPU is, by the numbers, more efficient. If we multiply x6, we get 96cores at 1020w. Just doing the quick numbers, 96cores at 947W doesn't seem all that more efficient by comparison.. Sure, it's better, but insanely better?

DeathtoGnomesI wanna know how big the AIO was.
Me too! Cooling this beast is likely going to require beastly cooling! We're likely talking car or truck radiator volume cooling.

Liquid nitrogen.

I have a theory that, during the Ryzen/EPYC chiplet testing phase, the cores that require less power to operate are allocated to the EPYC CPUs. Then, those that require a little more power are allocated to the Threadripper and laptop CPUs. And finally, those that require more power to operate are allocated to the desktop CPUs.

I wanted to see exactly which cooler was used.

at 200W its 12.5w per core.

Doesn't some of the I/O take that 200W of power?

Yes the I/O die is thirsty, but when measuring SOC power its included as is the memory controller... but only a dual channel one.
The epyc includes.... a 12 channel controller and 128 pcie lanes... soo a bit more overhead.

I mean, it is a datacentre CPU or an AI chip. One of the highest ones I might add.
