Compare CPUs

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

CPU 1

AMDRyzen 7 5800X

CPU 2

IntelCore Ultra 7 265

Note. Different sockets (AM4 and LGA1851): they are not interchangeable on the same motherboard. Switching from one to the other means changing the motherboard.

Warning. Different memory types between the CPUs (DDR4 and DDR5): the RAM from one will not work with the other.

Note. AMD Ryzen 7 5800X does not include integrated graphics: you need a dedicated graphics card.

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.
