LGA 1150,[1] also known as Socket H3, is a microprocessor socket used by Intel's central processing units (CPUs) built on the Haswell microarchitecture. This socket is also used by the Haswell's successor, Broadwell microarchitecture.[2]

LGA 1150 is designed as a replacement for the LGA 1155 socket, which is also known as Socket H2. The LGA 1150 socket has 1150 protruding pins that make contact with the pads on the bottom side of the processor. Cooling systems for LGA 1155 and LGA 1156 sockets are forward compatible with LGA 1150, due to them all sharing the same distance of 75 mm between each screw hole. Most motherboards with the LGA 1150 socket support varying video outputs (VGA, DVI or HDMI – depending on the model) and Intel Clear Video Technology.

Intel's Platform Controller Hub (PCH) for the LGA 1150 CPUs is codenamed Lynx Point.[3] Intel Xeon processors for socket LGA 1150 use the Intel C222, C224, and C226 chipsets.[4]

Second generation

On May 12, 2014, Intel announced the release of two 9-series chipsets, H97 and Z97.[19] Differences and new features of these two chipsets, compared to their H87 and Z87 counterparts, are the following:[20][21][22][23]

  • Support for Haswell Refresh CPUs out of the box
  • Support for the fifth generation of Intel Core CPUs, built around the Broadwell microarchitecture
  • Support for SATA Express, M.2[24] and Thunderbolt, though only if implemented by the motherboard's manufacturer
  • Two of the six SATA ports can be converted to additional two PCIe lanes for a total of ten, and used for providing the M.2 or SATA Express connectivity.[25] Intel refers to this variable configuration as Flex I/O or Flexible I/O.[26]

Motherboards based on H97 and Z97 chipsets were available for purchase the same day chipsets were announced.[27]

Notes

  1. ↑ Although these PCI Express lanes are provided by the CPU, the PCH limits their speed and possible configurations of PCI Express links.[13] Capacities may also be lower, depending on the used CPU model.
  2. ↑ Provided by the PCH. For Q87, H87 and Z87 chipsets, the number of available PCIe 2.0 ports is configurable and may be lower.
  3. ↑ Although chipsets may not support conventional PCI, motherboard manufacturers can include support through the addition of third-party bridges.
