The socket for installing central LGA 1155 processors is Socket, which has radically changed the alignment of forces in the segment of PC chips. If until this moment there was relative parity between Intel and its eternal rival, AMD, then this product in 2011 tipped the scales in favor of the first of them. The substantially redesigned semiconductor chip architecture allowed for phenomenal processor performance, and the integrated video adapter helped build even more affordable entry-level PCs.
Platform announcement and its development
This hardware platform was relevant from 2011 to 2013. It replaced the LGA 1156 connector , and then it was replaced by the LGA 1150 as planned. Well, at the moment it is gradually being superseded by the LGA 1151. Initially, the 6th chipset and the second generation of CPUs related to architecture under codenamed Core. A year later, the processor socket LGA 1155 received an update. Socket after that allowed the installation of a third-generation CPU, and it was possible to purchase more functional motherboards of the 7th series. Also, this family of central processors could be installed in earlier motherboards, but for this it was necessary to stitch the updated BIOS modification in them. The difference between the two generations of chips for this socket was that only the process of manufacturing semiconductor crystals was changed. If earlier it corresponded to 32nm standards, then a more recent family was already manufactured at 22nm and had higher clock frequencies at 100-200 MHz.
Chipsets
Socket 1155 motherboards were most often based on such sets of system logic:
Entry-level PCs were built on the basis of the H61 chipset. Moreover, this product was universal and perfectly suited for both generations of chips. The level of functionality was minimal, but sufficient for the same office PCs.
More advanced mid-level system units were already assembled on the B67 and B75 logic sets. In this case, there were improved hardware specifications, and this even made it possible to include several discrete graphics accelerators in the PC.
And the most productive PCs were based on the Z68 or Z77 chipsets. Their main “feature” was the ability to flexibly configure the system, and it was even possible to overclock any component of the PC separately (for example, RAM).
Processors
As noted earlier, immediately 2 generations of chips could be installed in Socket 1155. The processors were structurally identical and had 1155 contacts. The difference was only in the clock frequencies (in the 3rd family they were higher) and the technology for the production of silicon crystals (in more recent solutions, it corresponded to 22nm). The premium segment was occupied by chips of the i7 family. They were designated 26XX or 37XX, respectively, for the 2nd and 3rd generations. Also, the advantages of these CPUs include the ability to work in 8 computing threads, the maximum possible cache size (at the 3rd level, its size was 8 MB) and the highest frequencies.
Also, the CPUs from this family with the “K” index had an unlocked multiplier, and they could be overclocked with the proper equipment. Immediately after i7, i5 products were in terms of performance. They worked already in 4 data streams, had a reduced cache of 6 MB, and reduced clock speeds in comparison with the flagship products. They were designated 25XX, 24XX and 23XX (2nd generation) and 35XX, 34XX and 33XX (for the 3rd generation). Even lower in speed were the i3. They included only 2 hardware modules and 4 information processing streams. By analogy, these products were designated 21XX and 32XX. The initial level in this case was occupied by Pentium (designated as G8XX and G2XXX) and Celeron (G16XX and G18XX).
Prospects
Be that as it may, the LGA 1155 socket left a noticeable mark in the world of processor technologies. Socket made it possible to create even more powerful computing systems. They are still relevant today. Only when assembling a new computer is it more correct to pay attention to more recent Intel Core solutions. Socket 1155 has already managed to become outdated, and after it even a platform change has taken place. Now the most relevant products in this regard are those based on LGA1151. It will be them who will be correctly selected for the assembly of a new system unit.
Summary
Of course, in 2011 the processor socket with the number of pins 1155 was significant. Socket at that time provided a phenomenal level of performance. But now, 5 years after the start of sales, it is out of date. The rest of this hardware platform for the most part allows you to solve even the most complex tasks. But when choosing a new PC, it is better to look nevertheless towards more recent solutions from this manufacturer. Although they are more expensive, they are better in performance and energy efficiency.
