Core Ultra 7 265KF vs Core Ultra 9 285 comparison

In our benchmarks, the Core Ultra 7 265KF beats the Core Ultra 9 285 in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core Ultra 9 285 in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core Ultra 9 285 has slightly more cores than the Core Ultra 7 265KF. Indeed, the Core Ultra 9 285 has 24 cores compared to 20 cores found in the Core Ultra 7 265KF. It also has more threads than the Core Ultra 7 265KF. These CPUs have different clock speeds. Indeed, the Core Ultra 7 265KF has a significantly higher clock speed compared to the Core Ultra 9 285. Despite this, the Core Ultra 9 285 has a slightly higher turbo speed. In terms of cache, the Core Ultra 9 285 has slightly more L2 cache when compared to the Core Ultra 7 265KF. The Core Ultra 9 285 also has slightly 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 7 265KF has the same number of threads as cores. This means the the CPU does not support hyperthreading.
