Connector for CPU LGA1155 - Socket, cardinally changed the alignment of forces in the segment of chips for the PC. If, up to this point, there was a relative parity between Intel and its age-old rival, the company AMD, then this product in 2011 tipped the scales in favor of the first of them. The substantially redesigned architecture of the semiconductor chip allowed to achieve phenomenal performance of the processor part, and the integrated video adapter helped to assemble even more affordable PCs of the initial level.
This hardware platform was relevant inthe period from 2011 to 2013. It replaced the LGA 1156 connector, and then it was replaced by the LGA 1150. Well, it is currently being supplanted from the LGA 1151 market. Initially, for the assembly of such PCs, the 6th chipset and the second generation of CPUs, related to the architecture under the code-named Core. A year later I received an update to the LGA 1155 processor socket. Socket after that allowed the CPU to be installed already the third generation, and it was possible to purchase more functional motherboards already 7-series. Also this family of CPUs could be installed on earlier motherboards, but for this it was necessary to sew up in them an updated modification of the BIOS. 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 the norms of 32 nm, the more recent family was already manufactured at 22 nm and had higher clock speeds for 100-200 MHz.
Motherboards Socket 1155 most often based on such sets of system logic:
An entry-level PC was assembled based on a chipsetH61. And this product was universal and perfectly suited for both generations of chips. The level of functionality he had was minimal, but sufficient for the same office PCs.
More advanced mid-level system unitsalready gathered on the sets of logic B67 and B75. In this case, there were improved hardware specifications, and this made it possible even to include several discrete graphics accelerators in the PC.
And the most productive PCs were based onchipsets Z68 or Z77. Their main "chip" was the ability to flexibly configure the system, and you could even overclock any component of the PC separately (for example, RAM).
As noted earlier, two generations of chipscould be installed in Socket 1155. Processors in the constructive plan were identical and had 1155 contacts. The only difference was in the clock frequencies (in the third family they were higher) and the technology for the production of silicon crystals (for more recent solutions, it corresponded to 22 nm). The premium segment was occupied by chips of family i7. 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 computational flows, the maximum possible cache size (at the 3rd level, its size was 8 MB) and the highest frequencies.
Also, the CPU of this family with the index "K"had an unlocked multiplier, and they could be dispersed with the proper equipment. Right behind the i7 were the products of the i5 line. They worked already in 4 data streams, had a reduced cache - 6 MB, and reduced clock speeds in comparison with 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 located i3. They included only 2 hardware modules and 4 information processing flows. These products by analogy were designated 21ХХ and 32ХХ. The initial level in this case was occupied by the Pentium (designated as G8XX and G2XXX) and Celeron (G16XX and G18XX).
Whatever it was, but a notable mark in the worldprocessor technology left the connector LGA 1155. Socket allowed to create even more productive computing systems. They are still relevant to this day. Only when assembling a new computer is it more correct to pay attention to more recent Intel Core solutions. Socket 1155 has already become obsolete, and after it even a platform change took place. Now the most relevant products in this regard are those that are based on LGA1151. They will be selected correctly to build a new system unit.
Undoubtedly, in 2011 the processorconnector with a number of contacts 1155. Socket at that time provided a phenomenal level of performance. But now, 5 years after the start of sales, it is obsolete. In other respects, this hardware platform, for the most part, allows solving even the most complicated tasks. But when choosing a new PC, it's better to look at more recent solutions from this manufacturer. Although they are more expensive, they are better in terms of productivity and energy efficiency.
