Core Ultra 9 285K vs Core Ultra 9 275HX benchmarks

In our benchmarks, the Core Ultra 9 285K beats the Core Ultra 9 275HX in overall performance. Furthermore, our gaming benchmark shows that it also outperforms the Core Ultra 9 275HX in all gaming tests too.

When comparing these CPUs we notice that they have the same number of cores and the same number of threads. With our hardware info, we find that the Core Ultra 9 285K has a slightly higher clock speed than the Core Ultra 9 275HX. Also, the Core Ultra 9 285K has a slightly higher turbo speed. In terms of cache, both these CPUs have the same amount of L2 cache and L3 cache.

The more cores a CPU has, the better the overall performance will be in parallel workloads such as multitasking. Many CPUs have more threads than cores, this means that each physical core is split into multiple logical cores, making them more efficient. For instance, the Core Ultra 9 285K has the same number of threads as cores. This means the the CPU does not support hyperthreading.
