Land grid array has come with many CPU standard sockets for PCs. Among those LGA 1151 and 1155 are well-known devices for attaching your CPU to your motherboard.
However, sockets tell us the offspring of the CPUs. LGA socket’s name is dependent on the number of socket’s pins.
Are you swinging to choose on LGA 1151 or 1155? Haven’t worried. Just concentrate on this article.
In this article, we are going to equip you with an in-depth comparison of LGA 1151 vs 1155.
Difference Between LGA 1151 vs 1155
Though LGA 1151 and LGA 1155 both are acceptable for their performance, we show here some little difference.
LGA 1151 or socket H4, is to renew the configuration of LGA 1150 (known as H3 socket). This socket H4 has come with the latest Intel processors as of 2015.
LGA 1151 has arrived in two generations, while the first modification of this socket aid Intel’s Kaby Lake and Skylake. Alternatively, the Coffee Lake is assisted in second modification.
This socket has supported six varied chipsets like B150, H110, H170, Q150, Q170, and Z170.
LGA 1155, also named socket H2 is to renew the design of Socket 1156 ( known as H socket). This socket was introduced in January 2011.
The second offspring tried this socket based on Sandy Bridge and the third offspring founded on Ivy Bridge microarchitectures.
To include six new chipsets, this type of socket has a total of twelve motherboard chipsets. The Sandy Bridge processors contain H61,B65, P67, Q67,and Z68 chipsets. The Ivy Bridge has come to include Q75, B75,Q77, H77, Z77,and Z75 chipsets.

More About LGA 1151
LGA 1151 brings into the world two generations, we have mentioned. Now, we express here in detail.
First revision memory support
Maximum motherboards support DDR4 memory and a smaller number of the socket aid DDR3(L) memory.
Moreover, DDR4 and DDR3(L) are supported at the least number of motherboards. But you can install only one type of memory.
Second revision memory support
The second-generation motherboards aid only DDR4 memory.
Skylake, Kaby lake, and Coffee lake chipsets aid VT-d, Intel Clear Video Technology, Intel Rapid Storage Technology, and Intel Wireless Display Technology.
Depending on the motherboards model, LGA 1151 socket aid varying video outputs like DVI, HDMI 1.4 or Display Port 1.2.
Only motherboards qualified with Intel’s Alpine Ridge Thunderbolt controller aid HDMI 2.0 but VGA output is discretionary.
Skylake, Kaby Lake, and Coffee Lake don’t aid the Legacy conventional PCI interface.
This LGA 1151 socket works for Intel’s 6th offspring, 7th offspring, and 8th offspring core, Pentium, Celeron, Xeon E3, and Xeon E processors.
Now we present here the latest models of LGA 1151 socket.
|i9-9900T||Core i9 (Coffee Lake R)||$439.00|
|i9-9900KS||Core i9 (Coffee Lake R)||$513.00|
|i9-9900KF||Core i9 (Coffee Lake R)||$488.00|

More About LGA 1155
LGA 1155 comes with the latest generation of Intel Celeron, Pentium, Core, i3/i5/i7, and Xeon desktop and server processors.
This type of socket H2 works up to 4 CPU cores, up to 8MB of L3 Cache, and operates the frequency varying from 1.2 GHz to 3.7 GHz.
LGA 1155 also supports Dual-channel DDR3 memory with data up to 1600 MHz, Direct Media Interface 2.0 running at 5GT/s, and PCI Express 2.0 and 3.0 interfaces.
Without Independent Loading Mechanism the socket’s size is 1.67″ ×1.67″ (4.25cm×4.25cm).
