AMD-sponsored overclocker breaks Cinebench

by on26 September 2022

Ryzen 9 7950X overclocked to 6.5 GHz

AMD-sponsored overclocker Bill Alverson broke all records in Cinebench R23 and R20 for 16-core CPUs.

Alverson got his Ryzen 9 7950X overclocked to 6.5 GHz. His scores ranks 37th in R23 and 88th in R20 for CPUs of any size.

His score of 48,235 points in R23 is about 8,000 points ahead of an i9-12900KS overclocked to 7 GHz also on LN2. It is also 1,000 points or 30 per cent higher than the leaked scores of factory-clocked 7950Xs, and nearly 20,000 points higher than the regular scores of the 5950X.

The overclocked 7950X even entered the forbidden territory of the 32-core behemoths like Threadripper 3970X and outpaces Intel's 28-core Xeon W-3175X.

According to the screenshot submitted to HWBot, the overclock that won the R23 record was an x64.50 multiplier applied to the default 100 MHz bus frequency, resulting in 6450 MHz on all cores. It took 1.40 V and a peak power consumption of 271 W to reach it, 101 W more than the factory TDP.

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

Hardware monitors had a few difficulties with the second overclock. Benchmate recorded 6513.28 MHz, CPU-Z said 6538.38 MHz, and HWiNFO said that a 100.1 MHz bus frequency and an x64.63 multiplier resulted in an average clock speed of 6470.20 MHz. However all Alverson needed was to score 18,605 points and take the 16-core CPU record in R20.
