AMD Ryzen 9 7950X multi-core Cinebench R23 performance seemingly much better than previously rumored without needing 360 mm AIO cooling
A few days ago, we reported that the Ryzen 9 7950X scored 2,205 and 29,649 points in the single-core and multi-core Cinebench R23 runs. This single-threaded Cinebench R23 performance of the AMD chip was almost identical to the Core i9-13900K while the multi-threaded benchmark result fell quite short of the Intel Raptor Lake part which scored 35,693 when power limited to 250 W and 40,616 points without any power limitations.
A short time later, OneRaichu revealed that the Ryzen 9 7950X in the first Cinebench R23 run was thermal throttling and the CPU could achieve a score of 37,452 points but with a 360 mm AIO water block since the chip reached 95°C. Serial leaker Greymon55 now disputes these results and puts the blame for the Ryzen 9 7950X’s low multi-core performance vs the Core i9-13900K and bad temps on the BIOS.
Per Greymon55, the Ryzen 9 7950X can score more than 38,100 points in Cinebench without needing 360 mm AIO water cooling. The leaker mentions in a follow-up tweet that the CPU can achieve 38,300+ points with a 240 mm AIO. Greymon55 also thinks that, once the BIOS and voltage become better, the Zen 4 flagship will produce more than 40,000 points in Cinebench “relatively easily”.
If these numbers from Greymon55 are accurate, the Ryzen 9 7950X's Cinebench performance would beat the Core i9-13900K when the latter is power limited to 250 W.
When asked whether the CPU works fine with a high-end air cooler like the Noctua NH-D15, the leaker replied “Yes, at least high-end air cooler”.
Long story short, it appears that the Ryzen 9 7950X does produce a lot of heat but it looks manageable and you can potentially keep the CPU from thermal throttling with either a 240 mm AIO or a high-end air cooler. For more serious workloads where you need to push the processor to its max or even OC, a 360 mm AIO will likely be required to keep the temps below the thermal threshold.
Finally, nothing about the performance and the thermal output of the Ryzen 9 7950X can be said for certain until actual retail hardware is available. So, read the Cinebench results and temperature output mentioned here with a little caution.

Wait until the BIOS, voltage and more perfect, I think 40000+ should be relatively easy.
