Core Ultra 9 285K vs Core Ultra 9 285 specs and performance

According to the hardwareDB Benchmark tool, the Core Ultra 9 285K is faster 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 and the same number of threads. Our comparison shows that the Core Ultra 9 285K has a significantly higher clock speed compared to the Core Ultra 9 285. Also, the Core Ultra 9 285K 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 285K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
