Core i7-8700K vs Ryzen 5 7640U specs and performance

According to the hardwareDB Benchmark tool, the Core i7-8700K is faster than the Ryzen 5 7640U. Furthermore, our gaming benchmark shows that it also outperforms the Ryzen 5 7640U in all gaming tests too.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. Our comparison shows that the Core i7-8700K has a slightly higher clock speed compared to the Ryzen 5 7640U. Despite this, the Ryzen 5 7640U has a slightly higher turbo speed. The Ryzen 5 7640U outputs less heat than Core i7-8700K thanks to a significantly lower TDP. This measures the amount of heat they output and can be used to estimate power consumption. In terms of cache, the Ryzen 5 7640U has significantly more L2 cache when compared to the Core i7-8700K. The Ryzen 5 7640U also has slightly 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 i7-8700K has more threads than cores. Each physical core is split into multiple threads.
