LGA 1150 CPU List 2026: Complete Intel Processor Guide
If you’re maintaining or upgrading an LGA 1150 system in 2026, you need a comprehensive reference for compatible processors.
LGA 1150, also known as Socket H3, supports 4th generation Haswell and 5th generation Broadwell Intel processors released between 2013 and 2015.
I’ve compiled this complete list after analyzing Intel’s official specifications and motherboard manufacturer compatibility lists.
This guide covers all 90+ LGA 1150 processors, from high-end Core i7 chips to budget Celeron options, with detailed specifications and practical upgrade advice.
Understanding the LGA 1150 Socket (2026)
LGA 1150 is Intel’s Land Grid Array socket with 1150 pins, designed for desktop processors using the Haswell and Broadwell microarchitectures.
The socket replaced LGA 1155 and was later succeeded by LGA 1151, though these sockets are not cross-compatible despite similar pin counts.
Two processor generations use this socket.
Haswell processors (4th generation Core) launched in 2013 with 22nm manufacturing and support for DDR3 memory up to 1600MHz.
Broadwell processors (5th generation Core) arrived in 2015 with 14nm manufacturing, offering improved efficiency but limited desktop availability.
⚠️ Important: LGA 1150 processors only support DDR3 memory. They cannot use DDR4 RAM regardless of motherboard features.
The platform uses Intel 8-series chipsets (Z87, H87, B85) for Haswell and 9-series chipsets (Z97, H97) for both generations.
Most 9-series boards support Broadwell with a BIOS update, while 8-series boards typically require updates for Haswell Refresh processors.
