Core i9-9900K vs Ryzen 9 7950X comparison

Our benchmark analysis concludes that the Ryzen 9 7950X performs better than the Core i9-9900K. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-9900K in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Ryzen 9 7950X has significantly more cores with 16 cores compared to the Core i9-9900K that has 8 cores. It also has more threads than the Core i9-9900K. These CPUs have different clock speeds. Indeed, the Ryzen 9 7950X has a slightly higher clock speed compared to the Core i9-9900K. Also, the Ryzen 9 7950X has a slightly higher turbo speed. A Core i9-9900K CPU outputs less heat than a Ryzen 9 7950X CPU because of its significantly lower TDP. 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 7950X has significantly more L2 cache than the Core i9-9900K. The Ryzen 9 7950X also has significantly more 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 Core i9-9900K has more threads than cores. Each physical core is split into multiple threads.
