Core Ultra 9 285HX vs Core Ultra 9 285H benchmarks

According to the hardwareDB Benchmark tool, the Core Ultra 9 285HX is faster than the Core Ultra 9 285H. Furthermore, our gaming benchmark shows that it also outperforms the Core Ultra 9 285H in all gaming tests too.

When comparing core counts for these CPUs, we notice that the Core Ultra 9 285HX has significantly more cores with 24 cores compared to the Core Ultra 9 285H that has 16 cores. It also has more threads than the Core Ultra 9 285H. With our hardware info, we find that the Core Ultra 9 285H has a slightly higher clock speed than the Core Ultra 9 285HX. Despite this, the Core Ultra 9 285HX has a slightly higher turbo speed. The info from our database shows that the Core Ultra 9 285HX has more L2 cache than the Core Ultra 9 285H. The Core Ultra 9 285HX 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 9 285HX has the same number of threads as cores. This means the the CPU does not support hyperthreading.
