Earlier today we reported on the pricing, availability and specs of AMD’s Ryzen Threadripper processors. While we have just started knuckling down to some serious testing of Threadripper processors here at HEXUS towers, and reviews will published from 10th August onwards, there was a special OC event at Capsaicin SIGGRAPH 2017.
Under LN2 cooling and with various other overclocker tweaks a 16-core AMD Ryzen Threadripper 1950X has been coaxed to break 5.2GHz. As a reminder, the stock clocked 1950X runs at base/turbo clocks of 3.4GHz/4.0GHz so the overclock is a significant one. Furthermore, the overclock was achieved with all 16 cores active.
According to KitGuru, which took some nice photos of the LN2 cooling event, alongside the lashings of LN2, the system required “1.6 Volts to the CPU (1.55V plus 50mV offset) and… PCIe needs to be turned down from Gen 3 for maximum speed”.
The overclockers fired up the popular Cinebench application to test the extreme cooled Threadripper’s performance. At 4.8GHz the processor achieved 3688cb, pushed even further to 5.2GHz (x52 multiplier on 100MHz bus speed) the 16-core CPU’s score was boosted to an impressive 4122cb. TechPowerUp notes that the previous high for a 16-core CPU in Cinebench was 2867cb.
