AMD breaks world record for 16-core processors in Cinebench with 7950X on LN2

Congratulations! AMD-sponsored overclocker Bill Alverson, also known as Sampson, set two records for the highest Cinebench R23 and R20 scores on 16-core processors on Friday with a Ryzen 9 7950X processor overclocked to 6.5GHz. Its results now also rank 37th in R23 and 88th in R20 for processors of any size.

His check 48,235 points in R23 is about 8,000 points ahead of second place – i9-12900KS, overclocked to 7 GHz also on LN2. That’s about 11,000 points, or 30 percent, higher than the leaked factory-clocked 7950X scores, and almost 20,000 points higher than the regular 5950X scores.

The overclocked 7950X managed to beat other 16-core processors and enter the territory of 32-core giants like the Threadripper 3970X. It even outperforms Intel’s 28-core Xeon W-3175X released a couple of years ago, despite the overclocking race caused by this processor.

According to a screenshot provided by HWBot, the R23’s record-breaking overclock was a x64.50 multiplier applied to the default 100MHz bus speed, resulting in 6450MHz on all cores. It took 1.40V and a peak power consumption of 271W to reach it, which is 101W more than the factory TDP.

The system was an Asus ROG Crosshair X670E Gene motherboard paired with two sticks of 16GB DDR5 memory clocked at 3600MHz. The GPU was an RDNA2-based AMD Raphael integrated GPU clocked at 600 MHz. For the R20 record, Sampson rebuilt the system with an Asrock X670E Taichi motherboard.

The hardware monitors reported the second overclock in a very different way. Benchmate recorded 6513.28 MHz, CPU-Z said 6538.38 MHz, and HWiNFO reported that a 100.1 MHz bus and a x64.63 multiplier resulted in an average clock speed of 6470.20 MHz.

However, that was all he needed. check 18,605 points and take the 16-core record in the R20. In comparison, the highest scores for the 5950X and i9-12900K (LN2) are 15,664 points when overclocked to an even 6 GHz and 15,625 points when overclocked to 6,873 MHz, respectively.

After the launch of the 7950X and the rest of the 7000 series on Tuesday, we should see more overclocking records (and our reviews too!). Without exotic cooling, the processor has a clock speed of 5.7 GHz and a base clock of 4.5 GHz at an MSRP of $700.
