Intel CPU Socket Types and Timeline

Intel CPU socket identification made simple - Learn which CPU socket you have with this picture guide to Intel processor socket types.

1. Buying a new CPU and motherboard combo?

Scroll down to our Intel processor socket list below for compatible matches. You can also check out our recommended motherboard CPU combos for different computer types.

2. Buying a new CPU for your current motherboard?

Download and run CPU-Z. Click on the Mainboard tab and look for your motherboard chipset under the "Southbridge" field  (e.g. Z87, H77, H61 etc.). See our list below for CPUs that are compatible with your motherboard chipset.

You also can tell what type of motherboard you have by looking at its model name (e.g. Asus Z87-Pro, Gigabyte H77M-D3H, ASRock H61M-DGS, MSI H55M-E33).

3. Buying a new motherboard for your current CPU?

Download and run CPU-Z. Click on the CPU tab and look for your CPU model under the "Name" field (e.g. Intel Core i7 4790K). See our list below for motherboards that are compatible with your CPU.
