Ryzen 9 3950X vs Ryzen 9 5900X comparison

Our benchmark analysis concludes that the Ryzen 9 5900X performs better than the Ryzen 9 3950X. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 9 3950X in all gaming tests too.

With info from our database, we find that the Ryzen 9 3950X has slightly more cores with 16 whereas the Ryzen 9 5900X has 12. It also has more threads than the Ryzen 9 5900X. Our comparison shows that the Ryzen 9 5900X has a slightly higher clock speed compared to the Ryzen 9 3950X. Also, the Ryzen 9 5900X has a slightly higher turbo speed. Both these chips have an identical TDP (Thermal Design Power). This measures the amount of heat they output and can be used to estimate power consumption. The cache sizes of these CPUs are different. Indeed, the Ryzen 9 3950X has slightly more L2 cache than the Ryzen 9 5900X. However, both these chips have the same amount of L3 cache.

Most CPUs have more threads than cores. This technology, colloquially called hyperthreading, improves performance by splitting a core into multiple virtual ones. This provides more efficient utilisation of a core. Indeed, the Ryzen 9 3950X has more threads than cores. Each physical core is split into multiple threads.
