Core Ultra 9 275HX vs Core Ultra 9 285 benchmarks

According to the hardwareDB Benchmark tool, the Core Ultra 9 275HX is faster than the Core Ultra 9 285. Despite this, the Core Ultra 9 285 has the advantage in our gaming benchmark.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. With our hardware info, we find that the Core Ultra 9 275HX has a slightly higher clock speed than the Core Ultra 9 285. Despite this, the Core Ultra 9 285 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 275HX has the same number of threads as cores. This means the the CPU does not support hyperthreading.
