Core i9-14900K vs Core Ultra 9 285 specs and performance

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

Our spec comparison shows that they have an identical amount of cores but the Core i9-14900K has more threads. With our hardware info, we find that the Core i9-14900K has a slightly higher clock speed than the Core Ultra 9 285. In terms of cache, the Core Ultra 9 285 has slightly more L2 cache when compared to the Core i9-14900K. 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. Indeed, the Core i9-14900K has more threads than cores. Each physical core is split into multiple threads.
