Core i9-14900KS vs Core Ultra 9 285HX comparison

Our benchmark analysis concludes that the Core i9-14900KS performs better than the Core Ultra 9 285HX. Furthermore, our gaming benchmark shows that it also outperforms the Core Ultra 9 285HX in all gaming tests too.

Info from our database shows that they both have the same core count and the same number of threads. With our hardware info, we find that the Core i9-14900KS has a slightly higher clock speed than the Core Ultra 9 285HX. The cache sizes of these CPUs are different. Indeed, the Core Ultra 9 285HX has slightly more L2 cache than the Core i9-14900KS. However, both these chips have the same amount of 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 i9-14900KS has the same number of threads as cores. This means the the CPU does not support hyperthreading.
