Ryzen 7 5800H vs Core i7-7700K benchmarks
Our benchmark analysis concludes that the Ryzen 7 5800H performs better than the Core i7-7700K. Furthermore, our gaming benchmark shows that it also outperforms the Core i7-7700K in all gaming tests too.
When comparing core counts for these CPUs, we notice that the Ryzen 7 5800H has significantly more cores with 8 cores compared to the Core i7-7700K that has 4 cores. It also has more threads than the Core i7-7700K. These CPUs have different clock speeds. Indeed, the Core i7-7700K has a slightly higher clock speed compared to the Ryzen 7 5800H. Also, the Core i7-7700K has a slightly higher turbo speed. A Ryzen 7 5800H CPU outputs less heat than a Core i7-7700K 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 7 5800H has significantly more L2 cache than the Core i7-7700K. The Ryzen 7 5800H 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 5800H has more threads than cores. Each physical core is split into multiple threads.
