AMD Ryzen Threadripper 5990X processor overclocked to 4.82GHz, shatters 100,000 points in Cinebench R23 and achieves an 80% performance improvement over the stock chip

Extreme overclocker SkatterBencher has overclocked AMD’s unreleased Ryzen Threadripper 5990X HEDT processor to an impressive 4.82GHz across 64 cores on a custom waterloop configuration.

AMD Ryzen Threadripper 5990X processor overclocked to 4.82 GHz on its 64 Zen 3 cores to break 100,000 points in Cinebench R23

The AMD Ryzen Threadripper processor tested by SkatterBencher is the 5990X which is not a chip that the red team has officially released. In fact, it’s an engineering sample the overclocker was able to pick up that features 64 cores, 128 threads, 288MB of L3 cache, and clock speeds of up to 2.65GHz in stock (2 .27 GHz on average). The processor was tested on the ASUS ROG ZENITH II Extreme Alpha with 32 GB (8 x 4) of DDR4-2144 memory. For cooling, an EK-Quantum custom loop water chiller was used.

This specific sample is tagged with OPN code ‘100-000000443-40_Y’ which is similar to AMD Ryzen Threadripper 5000 samples that appear in various benchmark databases. This confirms the fact that AMD had standard Non-Pro chips as engineering samples, but decided not to release them for unknown reasons. Based on AMD’s recent HEDT strategy, it looks like the company will be primarily focused on workstations and the Pro segment, which means the standard Threadripper X-Series chips will be absent for the foreseeable future. The other important thing is that the processor works with the TRX40 ZENITH II Extreme while the Threadripper 5000WX processors are not meant to run on anything other than the more expensive WRX80 platform.


Now coming back to benchmarks, SkatterBencher is known to use all sorts of overclocking strategies including PBO, curve optimizers, and manual overclocking. The best results on the AMD Ryzen Threadripper 5990X CPU were achieved with manual overclocking, which isn’t such a big surprise. The only downside is the maximum boost frequency limited to a single thread, but the benefits of manual overclocking outweigh the cons and are better over PBO when looking for the highest performance gains. Each CCD was tested and out of the 8 CCDs on the Ryzen Threadripper 5990X chip, CCD4 provided the best tuning results, reaching up to 4.82 GHz at 1.45 V.

AMD Ryzen Threadripper 5990X OC vs. Stock CPU:

In terms of performance, compared to the original HEDT chip, the manually overclocked AMD Ryzen Threadripper 5990X processor achieved a more than 50% gain in the AI ​​benchmark, a 58% gain in Cinebench R23, and a performance increase over 80% in the 3DMark CPU Profile benchmark. The processor also broke the 100,000 (100,000) score barrier in multi-threaded Cinebench R23, which is just insane. While running Cinebench, the chip peaked at clock speeds of 4.525 GHz and CPU temperatures of up to 95°C. The CPU consumed an insane 691W of packet power with the manual overclock.

That’s not it, the overclocker also provides a guide to hitting 4.65 GHz in 5 minutes on the AMD Ryzen Threadripper 5990X CPU. Whether it will work the same with a 5995WX remains to be seen until users can buy the chip in the DIY segment. Some motherboards such as MSI WS WRX80, ASUS WRX80 PRO WS SAGE SE, ASRock WRX80 Creator and Gigabyte WRX80 SU8 offer overclock support on Threadripper Pro processors. This is confirmed by Tomshardware after being contacted by an official AMD representative as listed below:

[Editor’s Note: After publishing this story, an AMD representative contacted us via email, pointing out that the 5000 WX-series is actually unlocked for overclocking, contrary to the statements below. The company also provided a link to public documents about Threadripper 5000 WX that states, in part, ” Select WRX80 motherboards from our ODM partners will support both memory and CPU overclocking for users looking to push the limits of their workstation even further.”

AMD has confirmed that they aren’t done with Threadripper CPUs and will be releasing Zen 4 parts next year but whether they remain a Pro-only solution or come in DIY flavors for mainstream HEDT platforms remains to be seen.
