AMD Ryzen Threadripper 5990X CPU overclocked to 4.82GHz, breaks 100,000 points in Cinebench R23 and achieves 80% performance increase compared to stock chips

Extreme overclocker SkatterBencher overclocked AMD’s unreleased Ryzen Threadripper 5990X HEDT CPU to an impressive 4.82 GHz across all 64 cores in a custom water loop setup.

AMD Ryzen Threadripper 5990X CPU overclocked to 4.82GHz across all 64 of its Zen 3 cores to break 100,000 points in Cinebench R23

The AMD Ryzen Threadripper CPU tested by SkatterBencher is the 5990X, which is not a chip that the red team officially released. In fact, it’s an engineering sample that the overclocker was able to acquire, and it has 64 cores, 128 threads, 288MB of L3 cache, and clock speeds up to 2.65GHz in stock (2.27GHz on average). The CPU was tested on the ASUS ROG ZENITH II Extreme Alpha with 32 GB (8 x 4) DDR4-2144 memory. An EK Quantum custom loop water cooler was used for cooling.

This particular sample is marked with the OPN code “100-000000443-40_Y” which is similar to the AMD Ryzen Threadripper 5000 samples that appear in various benchmark databases. This confirms the fact that AMD had standard non-pro chips as development samples but decided not to release them for unknown reasons. Based on AMD’s recent HEDT strategy, it looks like the company will mostly focus on the workstation and pro segment, meaning the standard Threadripper X-series chips will be absent for the foreseeable future. The other important thing is that the CPU works with the TRX40 ZENITH II Extreme, while the Threadripper 5000WX CPUs are not meant to work on anything other than the more expensive WRX80 platform.


Getting back to the benchmarks, SkatterBencher has been known to use all manner of overclocking strategies including PBO, curve optimizer, and manual overclocking. The best results on the AMD Ryzen Threadripper 5990X CPU were achieved with manual overclocking, which is no big surprise. The only downside is the limited maximum single-threaded boost frequency, but the benefits of manual overclocking outweigh the downsides and compare better to PBO when fishing 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 4.82GHz at 1.45V.

AMD Ryzen Threadripper 5990X 100K Cinebench R23 Record:

AMD Ryzen Threadripper 5990X OC vs. Standard CPU:

In terms of performance, compared to the stock HEDT chip, the manually overclocked AMD Ryzen Threadripper 5990X CPU achieved an increase of over 50% in the AI ​​benchmark, an increase of 58% in Cinebench R23 and an increase in performance of over 80% in the 3DMark benchmark. CPU profile benchmark. The CPU also broke the 100,000 (100,000) point barrier in Cinebench R23 Multi-Threaded, which is just insane. During the Cinebench run, the chip reached a maximum clock rate of 4.525 GHz and a CPU temperature of up to 95 °C. The CPU consumed an insane packet power of 691W when overclocking manually.

It’s not, the overclocker also provides a guide to hit 4.65GHz in 5 minutes on the AMD Ryzen Threadripper 5990X CPU. It remains to be seen whether this will work with a 5995WX until users can buy the chip in the DIY segment. Certain motherboards like the MSI WS WRX80, ASUS WRX80 PRO WS SAGE SE, ASRock WRX80 Creator, and Gigabyte WRX80 SU8 offer overclocking support for Threadripper Pro CPUs. This is confirmed by Tomshardware after being contacted by an official AMD representative as quoted 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.
