AMD Ryzen Threadripper 5990X: More than 100,000 points in the CB R23 with 64 cores

AMD’s Threadripper processors, as the HEDT platform, have so far represented a compromise between many cores, as would be the case with Epyc in the server segment, and Ryzen processors for the desktop, which above all offer higher clock rates and corresponding gaming performance. So far, the top-of-the-line Threadripper is the Ryzen Threadripper 3990X, since the Threadripper Pro lineup is actually intended for workstations. The fastest chip in this series to date is the Ryzen Threadripper Pro 5995WX with 64 cores and an octa-channel memory interface for socket sWRX8, while the non-Pro models use socket sTRX4 and quad-channel and are not operated with Zen 3.

Now the overclocker “SkatterBencher” has overclocked a “Ryzen Threadripper 5990X” based on Zen 3 and achieved a score of more than 100,000 in Cinebench R23. The tested CPU is not officially available and is listed as an engineering sample with the identifier “100-0000000443-40_Y”. A release as a Threadripper is now very unlikely, since the focus is on the Pro models. Unlike the Pro models, it fits on the sTRX4 socket and clocks at up to 2.65 GHz as standard. It has 64 cores and 128 threads and 288 MiB L3 cache.

In the test, the sample was run with four 8 GiB DDR4 modules at 2,133 MHz on an Asus ROG Zenith II Extreme Alpha. A custom water cooling system was used for cooling. The best CCD of the CPU could be operated with 4.82 GHz at 1.45 volts. In order to achieve the maximum score of 100,191 points in Cinebench R23, however, clock rates of 4.325 – 4.525 GHz per CCD had to be selected due to the limited cooling. The processor’s average clock rate was 4.403 GHz at 1.265 volts. In his video, the overclocker describes the cooling as the limiting factor, since the CPU already reaches temperatures of 95 °C and the package power is an immense 691 watts.
