Core Ultra 7 256V vs Core Ultra 7 255H specs and performance

According to the hardwareDB Benchmark tool, the Core Ultra 7 255H is faster than the Core Ultra 7 256V. Furthermore, our gaming benchmark shows that it also outperforms the Core Ultra 7 256V in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core Ultra 7 255H has significantly more cores than the Core Ultra 7 256V. Indeed, the Core Ultra 7 255H has 16 cores compared to 8 cores found in the Core Ultra 7 256V. It also has more threads than the Core Ultra 7 256V. These CPUs have different clock speeds. Indeed, the Core Ultra 7 256V has a slightly higher clock speed compared to 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 Ultra 7 256V. The Core Ultra 7 255H 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. For instance, the Core Ultra 7 256V has the same number of threads as cores. This means the the CPU does not support hyperthreading.
