Core i5-7600K vs Core Ultra 7 255H specs and performance

Our benchmark analysis concludes that the Core i5-7600K performs better than the Core Ultra 7 255H. Furthermore, our gaming benchmark shows that it also outperforms the Core Ultra 7 255H in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core Ultra 7 255H has significantly more cores with 16 cores compared to the Core i5-7600K that has 4 cores. It also has more threads than the Core i5-7600K. Our comparison shows that the Core i5-7600K has a significantly higher clock speed compared to the Core Ultra 7 255H. Despite this, the Core Ultra 7 255H has a slightly higher turbo speed. The info from our database shows that the Core Ultra 7 255H has more L2 cache than the Core i5-7600K. The Core Ultra 7 255H also has significantly more L3 cache.

Modern CPUs generally have more logical cores than physical cores, this means that each core is split into multiple virtual cores, improving efficiency for parallel workloads. For instance, the Core i5-7600K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
