Ryzen 7 5800X vs Core i9-10900K comparison

According to the hardwareDB Benchmark tool, the Core i9-10900K is faster than the Ryzen 7 5800X. Despite this, the Ryzen 7 5800X has the advantage in our gaming benchmark.

With info from our database, we find that the Core i9-10900K has slightly more cores with 10 cores whereas the Ryzen 7 5800X has 8 cores. It also has more threads than the Ryzen 7 5800X. Our comparison shows that the Ryzen 7 5800X has a slightly higher clock speed compared to the Core i9-10900K. Despite this, the Core i9-10900K has a slightly higher turbo speed. A Ryzen 7 5800X CPU outputs less heat than a Core i9-10900K CPU because of its slightly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Ryzen 7 5800X has significantly more L2 cache when compared to the Core i9-10900K. The Ryzen 7 5800X 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 Ryzen 7 5800X has more threads than cores. Each physical core is split into multiple threads.
