AMD Ryzen 9 3900X 25% Faster than the Ryzen 9 3900X in CPU-Z Benchmark

As per a CPU-Z benchmark spotted by Twitter user HXL, AMD’s next-gen Ryzen 9 5900X will be as much as 25% faster in single-threaded workloads compared to its predecessor, the Ryzen 9 3900X. Based on the Zen 3 core architecture and a refined version of the 7nm node, a healthy IPC gain paired with boost clocks of around 5GHz should allow for a healthy performance uplift over the existing 3000 series:

Keep in mind that this chip is not recognized by CPU-Z, so the retail version may be even faster in the single-core benchmark. The multi-threaded scores are relatively tamer, being 15% faster than the 3900X, not surprising considering that the core counts are unchanged:


Compared to the Core i9-10900K running at its thermal velocity boost of 5.3GHz the single-core scores are nearly identical, with 5900X being 16% faster on the multi-threaded front. Not really all that impressive considering that the latter features two additional cores over the 10900K. Then again, this is an engineering sample and the 10900K here is running on a water-cooled setup, so it’s not exactly a fair comparison.
