Compare CPUs

Pick two processors (or up to four) and see how they differ in specs, price and performance.

CPU 1

IntelCore Ultra 9 285

CPU 2

Note. Different sockets (LGA1851 and AM5): they are not interchangeable on the same motherboard. Switching from one to the other means changing the motherboard.

Specifications

We highlight the best value in each row with a soft background. A higher or lower value does not mean the processor is better for you: it depends on how you use it.
