Are you planning on building a new computer or upgrading your existing computer with a Socket 1151 processor? You’ve come this far, so you’re in the right place. In this complete guide, we’ll be check Socket 1151 CPU List going through everything you need to know about LGA 1151 CPUs, including which generations of CPUs fit in the LGA 1151 socket, which CPUs are compatible with which motherboards, and which CPUs will give you the best performance for your individual needs!
What is Socket 1151 (LGA 1151)?
Socket 1151 (LGA 1151, H4) is Intel’s microprocessor socket for mainstream desktop CPUs. Launched in 2015 with Skylake microarchitecture, Socket 1151 has accommodated several generations of processors, making it among the most widely used CPU sockets in the last few years.
The “1151” part of the name simply refers to the number of pins in the socket that connect to the processor. AMD uses a PGA (Pin Grid Array) design where the pins are on the CPU itself. Intel uses an LGA (Land Grid Array) design that has the pins on the motherboard socket, and contacts on the CPU itself. Check the Intel’s official socket documentation.
Socket 1151 Generations: Important Compatibility Notes
Before diving into the CPU list, it’s crucial to understand that Socket 1151 comes in two versions that are physically identical but not cross-compatible:
- First-generation Socket 1151 (v1): Compatible with 6th gen (Skylake) and 7th gen (Kaby Lake) processors
- Second-generation Socket 1151 (v2): Compatible with 8th gen (Coffee Lake) and 9th gen (Coffee Lake Refresh) processors
Despite having the same physical dimensions and pin count, these two versions aren’t interchangeable due to power delivery and chipset differences. Always verify your motherboard’s compatibility before purchasing a CPU. Tools like PCPartPicker’s Compatibility Checker can help ensure your components will work together properly.
