What happened now? An overclocked AMD Ryzen Threadripper 5990X engineering sample in a custom liquid cooling circuit managed to score over 100,000 points in the Cinebench R23 multi-core benchmark. It came very close to breaking the world record set by the latest generation 3990X on liquid nitrogen.
YouTube overclocker scatterbencher I recently received an AMD Ryzen Threadripper 5990X engineering sample and started testing its overclocking capabilities. This 64-core processor is the unreleased successor to the Zen 3-based 3990X, offering only half the PCIe lanes and memory channels of the Threadripper Pro 5000 processors for the company’s workstations.
Since this is a TRX40-based processor, SkatterBencher used an Asus ROG Zenith II Extreme Alpha motherboard for testing and equipped it with an EKWB monoblock to water cool both the processor and the VRM on the board. It demonstrates several overclocking methods for this chip, including Precision Boost Overdrive (with and without Curve Optimizer) and manual overclocking for each CCX.
It ended up getting all 64 cores running at over 4GHz at the same time, with the best CCX hitting 4.825GHz during some benchmarks. With these settings, the processor achieved a stunning multi-core score of 100,191 in Cinebench R23, which is very close to World record. In comparison, our i9-12900KS scored around 29,000 on the same test.
As you can imagine, the 5990X requires a lot of power to maintain these frequencies. In fact, during Cinebench, the motherboard reported a power pack of almost 700W. The tilt angle of some CCDs exceeded 90 degrees, despite the fact that SkatterBencher used two massive radiators (1 x 480 mm + 1 x 360 mm) to cool only the processor.
Threadripper Pro 5000 processors have recently begun shipping to consumers after being exclusive to OEMs for several months. Some WRX80 motherboards will reportedly supports both memory and CPU overclocking, so maybe someone will be able to replicate the success of SkatterBencher with the 5995WX in the future.
