Core i5-13450HX vs Core Ultra 7 255H specs and performance
In our benchmarks, the Core i5-13450HX beats the Core Ultra 7 255H in overall performance. 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 i5-13450HX that has 10 cores. But they both have the same number of threads. With our hardware info, we find that the Core i5-13450HX has a slightly higher clock speed than the Core Ultra 7 255H. Despite this, the Core Ultra 7 255H has a slightly higher turbo speed. The cache sizes of these CPUs are different. Indeed, the Core Ultra 7 255H has significantly more L2 cache than the Core i5-13450HX. The Core Ultra 7 255H 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 i5-13450HX has more threads than cores. Each physical core is split into multiple threads.
