We assume in this article that you have already bought a motherboard for your computer and now you want to buy a new CPU for your motherboard. With this presumption in mind, the first and most important thing is to find out if your motherboard supports an INTEL or AMD CPU? The second most important thing is to find out the “socket type” your motherboard has. You can answer both these questions by reading the motherboard manual which would have come with your purchase or alternatively you can visit the motherboard manufacturer’s website to find which CPUs will be supported.
There are a number of socket types that support different types of CPUs as listed in the tables below. You can reference this table for selecting the right CPU for your CPU socket.
Intel based sockets and supported CPU’s
It is notable that INTEL socket type suggests itself the number of pins the relevant CPU has, hence is no need to guess. LGA here stands for Land Grid Array.
| SOCKET TYPE | CPU | ABOUT SOCKET |
| LGA 775 | Pentium 4, Celeron, Core 2 Duo, Xeon, and many other processors. | The most popular socket type by INTEL in the past also sometimes was referred to as socket T. It was superseded by LG 1156 (socket H) & LGA 1366(socket B) |
| LGA 1156 | Core i3/i5/i7, Celeron, Xeon | LGA 1156 processors superseded LGA 775 as they integrated northbridge architecture with the processor itself. |
| LGA 1155 | Core i3/i5/i7, Celeron, Xeon | Also called socket H2 used with sandy bridge and ivy bridge microarchitectures. |
| LGA 1366 | Core i3/i5/i7, Xeon | Also known as Socket B this type of socket did not support integrated graphics. |
| LGA 2011 | Corei7, Core i7 Extreme Edition, Xeon | This type of socket replaced LGA1366 for better performance in desktop and server performance |
| LGA 1150 | Core i3/i5/i7, Pentium, Celeron, Xeon | Based on Haswell and Broadwell architecture |
| LGA 1151 | Core i3/i5/i7, Pentium, Celeron, Xeon | Based on Skylake architecture |
| LGA 2066 | Core i5.i7/i9, Xeon | Also called socket R4 based on Skylake X and Lake X architecture |
AMD BASED SOCKETS AND SUPPORTED CPU’s
| SOCKET TYPE | PINS | CPU | ABOUT SOCKET |
| AM3 | 941 | Phenom II, Athlon II, Sempron, Opteron | Launched as a successor to AM2+ |
| AM3+ | 942 | FX | Launched to supersede AM3 with compatibility to AM3 processors |
| FM1 | 905 | A-Series | These sockets launched integrated graphic features |
| FM2 | 904 | A-Series | |
| FM2+ | 906 | A-Series | Used by AMD’s Kaveri APU & Godavari APU |
| G34 | 1974 | Opteron | Socket G34 supports four DDR3 SDRAM channel |
| C32 | 1207 | Opteron | |
| TR4 | 4094 | Ryzen Threadripper | Launched for support to Zen-based Ryzen Threadripper processors |
