Renowned overclocker Bill Alverson (screen name Sampson), sponsored by AMD, broke the record for the highest 16-core CPU score on both Cinebench R23 and R20 this Friday by overclocking the Ryzen 9 7950X to 6.5GHz. And it ranked 37th on R23 and 88th on R20 among all spec processors.
The overclocked 7950X manages to outperform other 16-core CPUs and has moved into the realm of 32-core behemoths like the Threadripper 3970X. Despite the processor’s overclocking race, it surpasses even Intel’s 28-core Xeon W-3175X from a few years ago.
According to a screenshot submitted to HWBot, the current overclock that set the new R23 record uses an x64.50 multiplier applied to the default 100 MHz bus frequency, resulting in all cores reaching 6450 MHz. reaching it required 1.40 V and 271 W of peak power consumption, 101 W more than the factory TDP.
The platform used for the overclock is the ASUS ROG Crosshair X670E Gene motherboard with two 16 GB DDR5 memory sticks at 3600 MHz. For the R20, Sampson rebuilt the system using the Asrock X670E Taichi motherboard.
The hardware monitor reported a completely different second to overclock. Benchmate recorded 6513.28 MHz, CPU-Z indicated 6538.38 MHz, and HWiNFO indicated 100.1 MHz bus frequency and x64.63 multiplier resulting in an average clock speed of 6470.20 MHz.
