Core Ultra 9 285H vs Core i9-9900KS specs and performance

According to the hardwareDB Benchmark tool, the Core Ultra 9 285H is faster than the Core i9-9900KS. Furthermore, our gaming benchmark shows that it also outperforms the Core i9-9900KS in all gaming tests too.

In terms of the number of cores of each of these CPUs, the Core Ultra 9 285H has significantly more cores than the Core i9-9900KS. Indeed, the Core Ultra 9 285H has 16 cores compared to 8 cores found in the Core i9-9900KS. But they both have the same number of threads. These CPUs have different clock speeds. Indeed, the Core i9-9900KS has a slightly higher clock speed compared to the Core Ultra 9 285H. Despite this, the Core Ultra 9 285H has a slightly higher turbo speed. The cache sizes of these CPUs are different. Indeed, the Core Ultra 9 285H has significantly more L2 cache than the Core i9-9900KS. The Core Ultra 9 285H also has significantly 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 9 285H has the same number of threads as cores. This means the the CPU does not support hyperthreading.
