Best LGA 1151 CPU [Socket H4 / Socket LGA1151 / Socket 1151] 2024

Socket 1151 was first release in August 2015 as a part of LGA1151 desktop platform. LGA 1151 release after success of socket 1150. Socket 1151 is a Land Grid Array type of socket which is use in 6th generation desktop Core microprocessors and 5th generation Xeon processors.

The CPU socket might be one of the essential features to consider while buying a motherboard. And the motherboard you will be buying altogether depends on the type of CPU you have. If your motherboard and CPU are not compatible, you will need a new motherboard with compatible sockets.

As for now, the latest processors by Intel require the LGA 1151 sockets. So let’s say if Intel releases a new CPU that is not compatible with the LGA 1151 socket, you will, unfortunately, have to buy another motherboard along with it to make it work. That is how vital a CPU socket is.

LGA 1150 vs. LGA 1151

The LGA 1150 socket supports CPUs built on the Broadwell and Haswell microarchitecture.

The following are some of the main differences between the LGA 1150 and LGA 1151

  1. LGA 1151 has one more contact than LGA 1150
  2. LGA 1150 supports Haswell, Broadwell, and Haswell-WS processors, while the LGA 1151 supports Skylake, Kaby Lake, and Coffee Lake.
  3. The LGA 1150 is used with Intel chipsets Series 8 and 9, while the LGA 1151 is used for the 100, 200, and 300 series.
  4. The LGA 1151 supports only DDR3 memory, while the LGA 1151 has support for DDR 4 memory.
  5. The LGA 1151 is the successor to the LGA 1150

AM4 vs. LGA 1151

The LGA 1151 is currently the latest socket for Intel, while the AM4 is the latest for AMD. What concerns us in this comparison is to see which socket is better for the future. PC enthusiasts always fear releasing a new type of socket along with a new processor, which would render their current motherboard useless.

Intel has had this problem of releasing new sockets too soon, making the older ones useless, giving them a bad reputation when you want to check which one will be more futureproof. Unfortunately, however, you can not predict when either of the manufacturers will pull out a new socket.
