Core Ultra 7 255HX vs Core Ultra 7 265 specs and performance

Our benchmark analysis concludes that the Core Ultra 7 255HX performs better than the Core Ultra 7 265. Despite this, the Core Ultra 7 265 has the advantage in our gaming benchmark.

Info from our database shows that they both have the same core count and the same number of threads. Both the Core Ultra 7 255HX and Core Ultra 7 265 have the same clock speed. Despite this, the Core Ultra 7 265 has a slightly higher turbo speed. When comparing cache sizes, these CPUs have an identical amount of L2 cache and 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 Ultra 7 255HX has the same number of threads as cores. This means the the CPU does not support hyperthreading.
