Sockel 1150 1155: Watercool HEATKILLER® IV Backplate INTEL 1150/1151/1155/1156 (10013) ModMyMods.com

The numbers 1150 or 1155 next to the name of the models of Intel processors and motherboards for them indicate the type of socket — a pad that allows the two main nodes of the system to interact with each other. The development of these interfaces is inextricably linked with the development of CPU lines, so they become obsolete and are replaced at the same time. In the characteristics, an indication of the socket is the most important information that determines the configuration of the system, because a mismatch is fraught with incompatibility between the processor and the motherboard. Let’s evaluate the difference between 1150 and 1155, and get ready for the choice of components. nine0009

LGA 1155 (or Socket h3) is a socket for Intel processors with 1155 pins released in 2011.

LGA 1150 (or Socket h4) is a socket for Intel processors with 1150 pins released in 2013.

As you can see, the numbers in the names of the sockets are by no means random — they coincide with the number of processor contacts intended for installation on the motherboard platform. These are physical indicators, and the practical difference between 1150 and 1155 lies in which CPU models can be used with them. In a word, it is not the connector that colors the system, but what is in the connector. nine0009

Socket comparison

The physical dimensions of both LGA types under consideration are identical: 37.5 x 37.5 mm. The number of contacts, respectively, is 1150 and 1155. Both their placement and the location of the key slots differ, so you won’t be able to accidentally install the processor in someone else’s socket. Manufacturers of cooling systems sometimes confuse the issue of compatibility by releasing coolers with mounts for 1150/1155. In this case, it seems to some users that the interfaces are identical, but in fact, the latches of the cooling systems are not related to the processor pads. nine0009

As mentioned, the LGA 1155 socket appeared in 2011 with and for SandyBridge processors. In 2012, the successor IvyBridge fit into the same connector, which received a performance boost and support for PCI-E 3.0. In 2013, the world saw Haswell with an interface already 1150, in 2014 DevilsCanyon joined the family, in 2015 — Broadwell, and they very successfully replaced the previous lines. It’s easy to see the difference between 1150 and 1155: two calendar years and four generations of Intel CPUs. One could say that the processors on these sockets are already outdated and out of date, but they are still on sale, moving from the top segment to the mass market. nine0009

Starting with the Haswell line, Intel processors received graphics cores from HD Graphics 4600 and higher, so we can assume that configurations based on LGA 1150 are in any case more powerful than 1155 in terms of the integrated video subsystem. However, it is the CPU that determines this gain, and not the socket.

Which socket is better, LGA 1150, LGA 1151, LGA 1155? — Habr Q&A

Which socket is better, LGA 1150, LGA 1151, LGA 1155?

The socket that fits your processor is best. nine0073 The others are worse.

Are they backwards compatible?

Depends on applied force.
If nature hasn’t cheated you with power, then you can shove any processor into any socket.

The socket is more important for hardware developers than for the user.
Intel already seems to have the sixth generation of their Core i3 / 5/7, sockets change along with the generations.
As far as I remember, their desktop processors had LGA1155 before Ivy Bridge, then they switched to LGA1150 / LGA1151 (the full list is on Wikipedia, and Yandex.Market also shows). I don’t remember about backward compatibility, it didn’t seem to be, or it was incomplete. nine0073 I personally do not see much point in taking a processor of previous generations (unless, of course, you buy for an existing motherboard), incl. if Intel, then Core i3 / 5/7 Skylake on LGA1151, or Haswell on LGA1150 — one powerful number crusher (although I didn’t notice a big difference in price during a quick inspection).

all bullshit except bees
none of the respected comrades mentioned memory at all
if you are concerned about the possibility of a further upgrade, you will suddenly find that there is no special choice

the situation is as follows: the most difficult to replace and most useful in a computer is memory you need: 32, 64 or maybe 128. Even if not now, but in the future.

then be aware that in a year the memory bars will be different — ie. already now it’s not possible to install DDR3, and take such motherboards — in a couple of years an upgrade of such a memory will cost more than a processor or a simple laptop

at this point, half or all of the sockets you listed will disappear

Here you suddenly find that for many i (7-5-3) — 64GB — the ceiling, but Xeon — that’s it.
