Core Ultra 9 285H vs Core Ultra 7 255H comparison

Our benchmark analysis concludes that the Core Ultra 7 255H performs better than the Core Ultra 9 285H. Despite this, the Core Ultra 9 285H has the advantage in our gaming benchmark.

Our spec comparison shows that they have an identical amount of cores and the same number of threads. With our hardware info, we find that the Core Ultra 9 285H has a significantly higher clock speed than the Core Ultra 7 255H. Also, the Core Ultra 9 285H has a slightly higher turbo speed. When comparing cache sizes, these CPUs have an identical amount of L2 cache and 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 9 285H has the same number of threads as cores. This means the the CPU does not support hyperthreading.
