Comparison Breakdown Between Two Intel Socket Types- 1151 & 1155
We’ll now check out the breakdown for different chipsets and other compatibilities. Some sweet recommendations will fill your thirst for the best PC upgrade.
Comparison for LGA 1151 vs LGA 1155 Motherboard
LGA 1155 socket supports 12 chipsets -6 from older models, and 6 chipsets are updated versions. These chipsets help each pin transmit fast data with proper efficiency. Some older-B65, H61, H67, Q67, P67, Z68. Ans some newer chipsets- B75, Q75, Z75, H77, Q77, Z77.
The LGA 1155 socket’s overall dimension is 1.67”x1.67”, perfectly fitting into any standard CPU case. And with 1155 pin count, it can give the best data transmission system with efficiency.
On the contrary, LGA1151 is the upgraded socket that comes with an 1151 pin count. The less pin does not feature any less data transmission rather, it provides more connection support with faster data transmission than the 1155 socket pins.
It supports 6 updated version chipsets- H110, B150, Q 150, H170, Q170, and Z170. The less pin count ensures faster data processing. For the maximum chipset support and upgraded featuring IC port, LGA 1151 is the best pick.
LGA 1151 Vs LGA 1155 Processor Compatibility
The Sky Lake processor is a 14 nm size microprocessor supporting Pentium, Celeron, Xeon, Core m3, Core m5, Core m7, Core i3, i5, i7, and i9 processor. And the Kaby Lake supports Pentium, Celeron, Xeon, Core m3, Core u3, i5, i7.
Later on, the second version of the 1151 socket was for the Coffee lake series that supports Pentium Gold, Celeron, Core i3, i5, i7, i9, and Xeon E.
LGA 1151 CPU socket supports dual-core, quad-core, and the second version supports up to 6 core processor. 1151 socket based CPU is compatible with the O/S of Windows 7, Windows 8, Windows 10, Microsoft.
Unlike, LGA 1151 socket, LGA 1155 motherboard supports Sandy Bridge and Ivy bridge. Both are 32 nm size processor. The Sandy bridge is compatible with Celeron, Pentium, Xeon E3, Xeon E5, Core i3, i5, i7 extreme series.
And the Ivy bridge is compatible with the Celeron G, Pentium G, Core i3, i5, i7, Xeon E3, Xeon E5, Xeon E7, and Xeon V2 series of processor. And all the 1155 socket CPU supports up to quad-core processors.
1155 socket based CPU is compatible with O/S Windows XP, Windows Server 2003, 2008, Windows 8.
LGA 1151 or 1155 Socket Memory Support
Intel LGA type of socket 1151 series supports DDR3, DDR3L, and DDR4 RAM. This gives you the opportunity for a faster memory support option with more memory bandwidth—the DDR3L features more economical Voltage consumption for fast data processing.
However, some also support up to 4 UDIMM option for laptop or notebook compatibility. And the advanced SATA connection of up to 4 port is also found sometimes. But you can install any one type of memory.
On the other hand, with LGA 1155 socket lets you connect only to DDR3 Ram. It is quite a faster data processing Ram, but you might not get advanced technologies like Voltage usage and faster data processing. Some socket comes with dual-channel memory connection also.
However, in Sandy bridge processors, DDR3-2133 speed is maximum, and in Ivy bridge, DDR3-1600 max speed with efficiency.
LGA 1155 Vs 1151 Cooler Compatibility Comparison
Both LGA 1151 and 1155 socket comes with 4 holes for the better heat sink to the CPU motherboard. Both types of Intel CPU sockets provide 75mm lateral length for the 4 holes in the socket for the fastest heat dissipation. Now, you can use any good cooling fan according to your PC work and load. The more heat your PC creates, the more effective fan you need.
LGA 1151 Vs LGA 1155 Compatible Connection Ports
All the processor chipset of LGA 1151 supporting is compatible with Intel ClearVideo technology and Wireless Display Technology (Varies from different motherboard). However, most of the motherboards with LGA 1151 socket supports DVI, HDMI port 1.4, Display port 1.2, and an optional VGA output option.
LGA 1151 socket compatible processors do not support the age-old traditional PCI interface. HDMI 2.0 is found supported only if the motherboard is compatible with Alpine Ridge Thunderbolt port. Also, USB connection port USB 3.1 or the Type-C port is available.
Unlike LGA 1151, 1155 CPU socket lets you connect with its PCI express compatible USB 2.0 and 3.0 ports. HDMI 2.0 output is available, of course. The Ivy Bridge processors offer up to 3 display ports. However, the low-end Intel chipsets used in the LGA 1155 socket sometimes lag in getting access to the SATA, Express, and Thunderbolt type advanced connection ports.

Which is better LGA 1151 Vs 1155?
This will be a tough decision to come up with the final for the 1151 Vs 1155 socket. Both have specific and impressive features with benefits that a greater PC upgrade needs.
However, nowadays, in the 2021 century, 1155 socket type PC is considered to have a dead CPU. Well, it might sound cheap, but you need to figure out what features you need. And according to that, get ready for your PC setup.
Our recommendation goes for the LGA 1151 socket for an overall wrap up as it comes with more updated connection availabilities and advanced technological features. It can be a better option if you are not thinking budget and want something for a future lead.
Sadly, some chipsets do not allow overclocking with 1155 sockets except the Z series chipset. So, better observe carefully before you go for the purchase.
