Socket 1155 was presented at the very beginning of 2011. Its appearance marked cardinal changes in the field of processor solutions, which led to a significant increase in computer performance.
The emergence of the processor platform and major innovations
In the first decade of 2011, sales of the updated Intel computing platform started, which was based on the Socket 1155 processor socket. The first significant innovation was the update of the computing part of processor devices, which made it possible to obtain a higher level of PC performance. The second important point is the implementation of the CPU and the integrated graphics processor on a single semiconductor chip with a tolerance of 32 nm.
The previous generation of chips, although it was carried out in one case, but consisted of 2 crystals. One of them is computing units with a built-in “north bridge” made using 32 nm technology, and the second is a graphics accelerator with a 45 nm technological process.
Another important difference from its predecessors is the support of the system logic chipsets for such important and faster interfaces as USB 3.0 and SATA 3.0. In 2012, an updated 3rd generation CPU line based on the same architecture was released for LGA 1155. They differed from their predecessors by an improved technological process (22 nm) and modified thermal paste under a metal cover.
The last nuance significantly worsened the overclocking potential of this CPU family. In 2013, Socket 1155 was replaced by an even more productive and high-speed Socket 1150. Well, after 3 years, another processor socket from Intel saw the light - LGA 1151. If you have a choice - Socket 1155 or 1150, then it’s better to choose from the standpoint of speed of the second of them. And in comparison with Socket 1151, all of its predecessors fade and lose significantly in technical parameters and speed.
Chipsets
Two generations of chipsets could underlie such a computer component for LGA 1155 as the motherboard. The Socket 1155 was oriented towards the use of sets of system logic related to the 6th or 7th series. The first one was released for the 2nd generation CPU. After updating the BIOS, it was also possible to install the 3rd generation of chips in it. Well, the 7th series was originally universal and allowed you to install both generations of CPUs at once. Conditionally, the chipsets in this case could be divided as follows:
The initial level was represented by only one product - H61. Only 16 GB of RAM and the lack of the possibility of any overclocking of the computing part made this product ideal for office PCs. Also in such a PC it was possible to install a maximum of 4 storage devices with SATA interface.
The average level included B65, P67 and Q67 for the 6th series and B75, Q75, Q77 and H77 for the 7th. In this case, the amount of RAM has already been doubled and amounted to 32 GB. The number of ports for drives has also been increased.
For the assembly of the most productive PCs, P67 (did not support the integrated graphics in the CPU) and Z68 in the 6th series of logic sets and Z75 and Z77 were already in the seventh. Products based on these sets of system logic had a significantly higher level of functionality and allowed to overclock almost any component of the PC (RAM, CPU or even a graphics accelerator).
CPU lineup
Socket 1155 was focused on installing 2nd or 3rd generation chips based on the best semiconductor architecture for CPUs - Core. Accordingly, the most productive chips in this case were marked 2XXX for the first of them and 3XXX for the second. This is i3, and i5, and i7.
It was also possible to install Celeron or Pentium ruler chips in LGA 1155. Socket, processors, and other components of the computing system were unified, and it was possible to install the most efficient chip in the entry-level motherboard or, on the contrary, put the least efficient CPU in the most modest fee.
Future of this platform
Of course, today there is no longer a dilemma - the Socket 1155 or 1150. The current solution for 2016 is the LGA 1151 processor socket, which is focused on installing chips based on the most advanced architecture for the 6th generation Core CPU. It is to him that you need to pay attention when assembling a new system unit. The processor sockets LGA 1150 and the older LGA 1155 are slowly leaving the historical arena. But their performance is quite enough to solve any problem today, so it's too early to think about upgrading such a PC. It makes sense to pay attention to components only if you need to repair the system unit, which is based on this particular computing platform.
Summary
For 2011, Socket 1155 was a breakthrough solution. He laid the foundation upon which more recent and productive central processors were developed. Including Core chips marked 6XXX (that is, CPUs based on this architecture are already the 6th generation). Otherwise, this platform is slowly disappearing into oblivion. Its components can still be found on store shelves. But there’s no point in acquiring them when building a new PC. There are more relevant products that are based on LGA 1151, and it is on them that you need to pay attention when assembling or bundling a new personal computer.
