Intel with built-in DDR-III memory controllers (two channels) and pCI-E tires 2.0 (16 lines), as well as with support for processors with an integrated graphics adapter, replacement Socket LGA1156 and Socket LGA775. In the future, for this connector will be released with the number of cores up to eight.
What is Socket LGA1156?
Connector for desktop intel processors With built-in DDR-III memory controllers (two channels) and PCI-E 2.0 tires (16 lines), as well as with support for processors with an integrated graphics adapter, replace Socket LGA775. Currently, the Core i3, i5 and i7 8xx families are produced for this processor connector, as well as cheap processors under the Pentium brand.
What is Socket LGA1366?
Connector for new Desktop and server processors Intel, with built-in DDR-III memory controllers (three channels) and QPI bus (one channel at desktop processors and two - in server), replacement both Socket LGA775 (for high-performance single-processor systems) and Socket LGA771. Currently, for this processor connector, processors of families of the I7 9xx and Xeon 55xx families are issued. The key difference between the latter is to support dual processor configurations.
What are the differences between the Socket LGA1155 and Socket LGA1156 connections and the processors for them? Are they compatible with each other?
Despite the external similarity of the connectors, among themselves are completely incompatible, i.e. LGA1155 Processor Cannot be installed in the LGA1156 fee and setMoreover, this mechanically prevents the location of the keys in the connector. Also, the main differences between LGA1155 processors and chipsets compared to LGA1156 analogs are twice the faster version of the DMI bus, which connects to the chipset, which allows you to eliminate the "bottleneck" when using SATA 6GB / S and USB3.0 controllers.
What are the difference between the Socket LGA1156 and Socket LGA1366 connections and the processors for them? Are they compatible with each other?
LGA1156 The processor is physically not installed in the LGA1366 connector and vice versa, despite similar names of processors for both sockets.
The key differences of all three sockets are reduced to the table:
What memory can C Socket LGA1155, Socket LGA1156 and Socket LGA1366 and Socket LGA1366 and SOCKET LGA1366 processors?
Since the memory controller is integrated into the appropriate processors, then support different types The memory also depends on the type of installed, currently all boards and processors with these sockets are designed to work with the memory of the DDR-III memory, the most officially supported frequency of modules depends on specific model The processor, however, there are some patterns - all LGA1155 and LGA1156 processors (Core i5 and Core i7 8xx) and all LGA1366 Core i7 processors support only non-buffered ("ordinary") DDR-III up to PC10600 (1333 MHz), and Xeon processors For Socket1366, ECC and ECC + REGISTERED modules are also maintained in combination with the corresponding boards, while nebuperized modules also work in them.
To achieve optimal performance, the number of memory modules in LGA1155 and LGA1156 systems should be multiple by two, in single-processor LGA1366 system - three, and in a two-processor - six.
What colaers can C C C SOCKET LGA1155, Socket LGA1156, and Socket LGA1366 processors?
Mounting coolers for LGA1155 and LGA1156 sockets is identical and not compatible with LGA1366, both of these types of fasteners are not compatible with any of the previously produced sockets. Nevertheless, for some expensive coolers, sets of fasteners were released, allowing them to put them on such, and most new universal coolers already support such connectors.
List of compatible coolers in Nixes Nomenclature can be viewed here: , .
What power supplies can be used with Socket LGA1155, Socket LGA1156 and Socket LGA1366 processors?
No specific requirements of the board with these sockets on BP are not imposed, the selection of BP is carried out according to the same principles as for Socket LGA775 and Socket LGA771 systems based on the requirements of a particular configuration.
How the performance of processors with the NEHALEM architecture for Socket LGA1156 and Socket LGA1366 is connected to each other and with processors with architecture Intel Core for socketlga775?
As a rule, with an equal nominal clock frequency and the number of cores of LGA1366 processors, the processors are slightly faster than LGA1156 processors, but also those, and others significantly (up to 40%) exceed their LGA775 precursors from the Sore 2 Quad family.
How the performance of processors with the Nehalem architecture for Socket LGA1156 and processors with architecture correlates Sandy Bridge. For Socket LGA1155?
As a rule, with an equal nominal clock frequency and the number of LGA1155 cores, the processors are approximately 15-17% faster than LGA1156 processors due to architectural differences themselves.
1155 - Socket, radically changing the placement of forces in the segment of the chips for PC. If until this moment was the relative parity between Intel and her eternal rival, the Amd company, then this product bowed the scales in addition to the first of them. The essentially recycled architecture of the semiconductor crystal made it possible to achieve the phenomenal speed of the processor part, and the integrated video adapter helped collect even more affordable entry-level PCs.
Announcement platform and its development
This hardware platform was relevant from 2011 to 2013. She came to replace the connector and then her planned replaced LGA 1150. Well, and on this moment Gradually displaces the LGA 1151 from the market. Initially, the 6th set of chips was released for the assembly of such PCs and the second generation of the CPU architecture under the core code name. A year later, the processor connector LGA 1155 was updated. The socket then allowed to install the CPU for the third generation, and it was possible to purchase more functional system boards of the 7th series. Also, this family of central processors could be installed in earlier system boards, but for this it was necessary to sew the updated bios modification in them. The difference between the two generations of chips for this socket was that the process of production of semiconductor crystals was changed. If earlier it corresponded to the standards of 32nm, then a more fresher family has already been manufactured on 22nm and had higher clock frequencies at 100-200 MHz.
Microcham Sets
Motherboards are most often based on such sets of system logic:
The initial level PC was assembled on the basis of the H61 chipset. Moreover, this product was universal and perfectly suitable for both generations of chips. The level of functionality was minimal, but sufficient for the same office PCs.
More advanced system blocks The average level has already been collected on the sets of logic B67 and B75. In this case, there were improved hardware specifications, and this allowed to even include several discrete graphic accelerators in the PC.
And the most productive PCs were based on Z68 or Z77 chip sets. The main "chip" was the possibility of flexible system settings, and it was possible to even dispersed any PC component separately (for example, RAM).
Processors
As noted earlier, at once 2 generation of chips could be installed in Socket 1155. The processors in a constructive plan were identical and had 1155 contacts. The difference only consisted in the clock frequencies (the 3rd family was higher) and the technology of producing silicon crystals (in more fresh solutions it corresponded to 22nm). Premium segment occupied chips of the I7 family. They were denoted by 26xx or 37xx, respectively for the 2nd and 3rd generations. Also, the advantages of these CPUs include the possibility of working in 8 computing flows, the maximum possible amount of cache (at the 3rd level its size was 8 MB) and the highest frequencies.
Also, the CPU from this family with the index "K" had a unlocked multiplier, and they could be dispersed with due configuration. Immediately for I7, the productivity levels of the I5 line were in terms of performance. They already worked in 4 data streams, had a reduced cache - 6 MB, and reduced clock frequencies in comparison with flagship products. They were referred to 25xx, 24xx and 23xx (2nd generation) and 35xx, 34xx and 33xx (for the 3rd generation). Even below, the speed was located i3. They included only 2 hardware modules and 4 information processing streams. These products are indexed by 21xx and 32xx. First level In this case, Pentium was occupied (designated as G8XX and G2XXX) and Celeron (G16xx and G18xx).
Perspectives
Whatever it was, and noticeable In the world of processor technologies, I left the LGA 1155 connector. Socket allowed to create even more productive computing systems. They are still relevant to this day. Only here when assembling a new computer it is more correct to pay attention to the more recent Intel Core solutions. Socket 1155 has already managed to become out of order, and after it even occurred a change of platform. Now the most relevant products in this plan are those based on LGA1151. It is them that will be correctly chosen to build a new system unit.
RESULTS
Of course, the iconic was in 2011 a processor connector 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, he is outdated. Otherwise, this hardware platform is mostly allowed to solve even the most complex tasks. But when choosing a new PC, it is better to look at the side of more than recent solutions from this manufacturer. Though they are more expensive, but in performance and energy efficiency is better.
If you wondered if you probably do the system upgrade. Or collect a new one. Or you gave you too detailed feature Already collected system blocks, and you do not know what to stay. In this case, knowledge is the best adviser, so let's see what is hidden behind the numerical notation with one single difference.
Typically, the transition to a new socket coincides with the appearance of a new line of processors. Intel In this case, it is not an exception: first LGA775 gave way to LGA1156, and he, in turn, gave the LGA1155 road. To date motherboards Intel processors are available with LGA2011, LGA1150 sockets, and LGA1155 goes into the past. However, most home systems on Intel processors are still collected on the latter.
Definition
Socket LGA1156. - a connector on a motherboard designed for Intel processors that have been labeled Core i3, i5, i7, Pentium G69x0, Intel Celeron G1101 and Intel Xeon X, L (Clarkdale and Lynnfield kernels). Supports the operation of the two-channel memory of the DDR 3 standard, PCI-E 2.0 bus, as well as integrated into the processor graphic kernel. The production of LGA1156 motherboards launched in 2009.
Socket LGA1155 - The connector on the motherboard, which came to replace the LGA1156, and intended for the processors of Intel Sandy Bridge and Ivy Bridge. The production of LGA1155 motherboards launched in 2011.
Comparison
Physically both sockets are very similar, it is almost indistinguishable. Abbreviation LGA (Land Grid Array) speaks about constructive features Corps of the processor - the presence of a matrix of contact pads. The conclusions of the processor in this case are sprinkled in a socket on the motherboard. This allows transportation and installation of processors without applying additional security measures. Fastening provides a pressure lever.
It can be said that the difference between the two sockets is the title, or rather, in its digital expression. 1156 and 1155 is the number of legs of the legs. Another constructive difference between LGA1155 - the keys removal is located to the right of the conditional central axis of the case - instead of 9 mm, the distance is 11.5 mm. It was done so that the deft hands would try to make friends the LGA1156 socket with the Save Bridge family processor, for example.
Despite the physical similarity of sockets, cross-platform in our case there is no and can not. Processors from one to another under no circumstances will fail. Technologically, the difference between LGA1155 and 1156 is supported by the first DMI 2.0 bus, more quickly compared to DMI. In practice, this gives a high bandwidth of the "bridge" between the processor and the chipset, which ensures support for the work and new controllers.
Despite the difference between processors installed in sockets (and, as a result, different heat generation indicators), cooling systems for LGA1155 and 1156 are fully compatible, because when switching from one platform to another, there is an opportunity to save at least it. With the replacement of some technologies to others (even if with such minor differences), outdated options are quickly leaving the market, because today to meet motherboards with the LGA1156 socket is almost impossible. Processors for this intel socket Stopped to produce in 2012, respectively, and technical support does not turn out. However, the share of LGA1155 on the market also decreases.
Conclusions Site
- LGA1155 appeared in 2011, LGA1156 - in 2009.
- LGA1156 Designed for the Core line processors and a number of others, LGA1155 - for the Sandy Bridge line and Ivy Bridge.
- In LGA1156, one pin is more.
- The wrench from the LGA1155 is right.
- LGA1155 supports DMI 2.0 bus (provides adequate operation of SATA 3.0 and USB 3.0).
- LGA1155 is a newer version, LGA1156 - outdated and removed from production.
For the first time, the Sandy Bridge processors with the LGA1155 appeared in 2010, coming to replace not the most successful processors with the LGA1156 connector and the LynnField core. New processors had more productivity and at the same time he was noticeably buried. Models with unlocked multiplier allowed to achieve record at the time of the frequency output. In 2012, the light saw processors with the Ivy Bridge core, using the same processor connector LGA1155. These chips belong to the third generation and differ, first of all, support for PCI-E version 3.0. Because of this, and supporting them as quickly as Sandy Bridge have gained popularity. This was facilitated by video card manufacturers by releasing top solutions with such an interface. The sake of objectivity should be noted that the processors of the third generation had a smaller overclocking potential compared with the second generation.
Socket LGA1150
Socket LGA1155
The fourth generation processors, Haswell, replaced Ivy Bridge. They brought with them not only a new level of performance, but also new processorconnector. The graphic processor has undergone serious upgrades, and the performance has reached values \u200b\u200bthat allow it to be quite comfortable to play unpretentious games. Almost simultaneously with the fifth generation, the fifth generation processors with the Broadwell core, which, with a lower power consumption, provide a productivity similar to Haswell.

To compare productivity, consider 3 senior processors of the second, third and fourth generations. The fifth generation does not consider much sense, since these CPUs are created not for the sake of high performance, but to improve performance on Watt. Therefore, they are inferior in the speed of the fourth generation processors.

According to the results of the tests, it can be seen how the productivity of processors from generation to generation increased. The exception is a game test based on the game Crysis Warhead. This is due to the fact that this game uses only one processor kernel in the work, and the main performance criterion is the clock frequency. It can be seen that Core i7-3770 as having the lowest clock frequency showed minimal performance. All old games behave in a similar way, therefore, if you like World of Tanks or the same CRYSIS, then changing the second or third generation processor is meaningless. For modern games, such as GTA 5, Witcher 3 or Project Cars, a newer processor will allow better performance. For such tasks, like editing photos and video, mathematical calculations, and so on, go with it makes sense. Especially considering the fact that modernization will require replacement only. The remaining components can be used from the old system.
Turn to power consumption. Consider the Core i7-2700K processors, Core i7-3770k, Core i7-4790K, installed in the system where the second notable consumer of energy is video Card Radeon. HD 7970. The processor load provided a performance test built into the 7Z archiver and capable of loading all processor kernels in the system
It depends on the power consumption of the processor. Those. The more consumes the processor, the better it needs to be cooled. Accordingly, the cooling system of a more economical processor will work quieter. From the table with power consumption tests it is clear that the second generation Core processors have the highest power consumption. With the processors of the third and fourth generation, everything is more complicated. Tested processors have shown a funny result: the Core i7-4790K is better turned out to be better, and under the load - Core i7-3770k. However, it is worth considering that modern processors Pretty rarely work with full load, so it is important that the CPU can effectively reduce power consumption. Based on this, it can be argued that in non-expert modes of operation, the Core i7-4790k will be at the Core i7-4790K.
Relatively not so long ago it was possible to observe the abundance of solutions based on x86-architectures from different manufacturers. AMD, Cyrix, Intel, Via, Nec, Nexgen, Transmeta, Sis, UMC - all of them produced integrated circuits, suitable for a certain range of tasks. Today we can celebrate only two players in the market, which, however, do not need in the presentation.
Despite the excessively modest list of manufacturers of central processors for desktop systems, now the user's head is circling the number of models of finished devices. Celeron, Pentium, Core i3, Core i5, Core i7 - Here is just a list of lines modern solutions Intel. How not to get lost in the labyrinth of all these names?
Modern Central Processors and Platforms
Intel Haswell (LGA1150)
Processors built on the basis of Haswell microarchitecture, on this moment are a crown of creation intel companies. Chips are manufactured by 22-nm technical process. Architecture itself in comparison with Ivy Bridge received a number of significant changes and refinement:
- new sets of instructions AVX2.0 and FMA3 are used;
- enharged bandwidth Cache;
- the buffer and queues are increased, including reordering buffer;
- directly to the processor is built in the IVR voltage regulator;
- with six units up to eight, the number of start ports is increased, as well as new actuators are added;
- added new energy-saving modes;
- increased virtualization speed.
