Intel processor sockets. What is the difference between socket LGA1150 and LGA1155 and which is better? Difference between sockets 1150 and 1155 1151
Hello, technoblog readers. Today I will tell you which processors are suitable for socket 1151 (Skylake, Kaby Lake), as well as 1151v2 (Coffee Lake). In this article we will try to talk about the most powerful, inexpensive and inexpensive Intel Core, Pentium and Celeron chips.
The list of CPUs will be arranged in a list so that you have a more accurate idea of the models on the market.
And yes, it’s worth making an important clarification: socket LGA1151 does not imply backward compatibility with 1150 and does not support Xeon server processors.
Processor compatibility table
Socket 1151 from Intel is very insidious in its essence, since it has 2 versions: the first supports chips of the 6th and 7th generations, and the second - only the 8th. In terms of attitude, the picture is much simpler, but this is not about him. 
Let's see which ones, as well as i3, i7, Pentium and Celeron are capable of running the 1151 Gen 1. 
Now let's look at the line of chips that will fit a motherboard with socket 1151v2. 
In 2018, 9th generation CPUs were added to the previous list. 
Optimal processor for its price
Now comes the most interesting part of the comparison. We have indicated which processor is suitable for a specific socket. Now it remains to decide on the model of the chip itself. If you want to learn more about CPUs, we recommend reading this article. 
Now let’s take a look at the brightest representatives of the 6th, 7th and 8th generations:
Skylake– Intel i5 6400T engineering sample. At one time, this processor made a lot of noise because it had an extremely low cost, 4 productive cores with a frequency of up to 2.8 GHz and a very modest thermal package of 35 W.
Kaby Lake– Intel Pentium G4620. The so-called “Hyperpen” became a cult among gamers at the time of its release, as it offered the functionality of the Intel Core i3-7100 at a significantly lower cost. It is also worth mentioning the peppy mid-range i5-7400 and the top-end version i7-7700k, which has 4 cores and 8 data processing threads. The stone is still considered a relevant, powerful and interesting solution for progressive systems, and also supports overclocking up to 5 GHz with a multiplier.
Coffee Lake– i5-8400. The advent of the 8th generation of Intel chips added not only a new socket, but also 2 additional cores for each line, with the exception of Celeron and Pentium. Having a 6-core processor that can automatically increase the frequency from 2.8 to 4 GHz is a very successful investment in the future and therefore I confidently recommend it (at the prices of the i5 you can figure this out (especially since many people are familiar with this discounter as a reliable and verified seller)).
Difference between1151 and 1151v2
It has long been no secret that the processor socket designed for system logic sets of the 100th and 200th series is completely incompatible with the 300th. And it's not even that Intel wants to make more money. The introduction of additional cores forced engineers to radically rework the power supply circuit of Coffee Lake processors to ensure stable operation of the chips, even under extreme overclocking. 
Key changes affected the VCC (power) and VSS (ground) pads. At the same time, the number of previously reserved RSVD contacts has decreased slightly. So the situation is as follows:
| Skylake/Kaby Lake | Coffee Lake | |
| VCC | 110 | 128 |
| VSS | 364 | 378 |
| RSVD | 46 | 25 |
As you can see, it is physically impossible to “make friends” of old chips with new motherboards, just like plugging a Chinese plug into a European socket. Yes, there are enthusiasts who managed to get Kaby Lake on the Z370 by modifying the BIOS, but the lion's share of functions in this case were unstable, and the rest were completely absent.
So if you have a lot of free time, you can try it, but I strongly do not recommend it.
I hope that the article was useful to you, so comment and share with your loved ones. See you in new articles. Bye.
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 contact 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 outdated and replaced at the same time. In the specifications, an indication of the socket is the most important information that determines the system configuration, since a mismatch can lead to incompatibility between the processor and motherboard. Let’s evaluate how the 1150 differs from the 1155 and prepare for the selection of components.
LGA 1155(or Socket H2) is a 1155-pin socket for Intel processors, released in 2011.
LGA 1150(or Socket H3) is a 1150-pin socket for Intel processors, 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 pad. These are physical indicators, and the practical difference between 1150 and 1155 is which specific CPU models can be used with them. In short, it’s not the connector that makes the system, but what’s in the connector.
Comparison
The physical dimensions of both LGA types under consideration are identical: 37.5 x 37.5 mm. The number of contacts is 1150 and 1155, respectively. Their placement and the location of the key slots differ, so it will not be possible to accidentally install the processor in someone else's socket. Cooling system manufacturers sometimes create confusion about 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.
As mentioned, the LGA 1155 socket appeared in 2011 with and for SandyBridge processors. In 2012, the successor IvyBridge fit into the same connector, receiving a performance increase and support for PCI-E 3.0. In 2013, the world saw Haswell with an interface of 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 the 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 have fallen out of favor, but they are still on sale, having moved from the top segment to the mass one.
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 built-in video subsystem. However, this gain is determined by the CPU, and not the connector.

LGA 2011.
First of all, low prevalence. In case of problems, it is difficult to find the motherboard. Only enthusiasts have such computers. There are many times more ordinary motherboards.
More sizes. You need a huge cooler and a huge case.
Now imagine, putting all this brute after you at work, or for dad, mom, etc... Few people will like a huge and heavy system unit.
Energy consumption. It will always eat a lot, even when idle, much more than a regular i5 and i3.
Price. A solution to LGA 2011 will be expensive.
Performance. Windows and the browser will not appreciate it; they will work the same as on a modern Core i3.
The games will be appreciated, but only the most modern ones, 12 channels then. And often I want to play old games.
Great idea to play CS 1.6 on a 6 core i7 with a TDP of 140 W. Super!!!
Modern life also doesn’t allow you to play a lot; there’s simply no time.
The 6-core will just stand there, or at best distribute torrents. For this, it is also simply necessary :))) Just kidding, for torrents you don’t need a powerful processor, you need more RAM.
You can buy such a 6-core processor for permanent archiving, video encoding, and more. But even here he may not justify himself yet.
Overall, LGA 2011 is a bold decision. But an experienced investor is unlikely to invest his money in this, since the benefits are highly controversial.
But the LGA 2011 will be bought by an enthusiast, primarily for self-satisfaction.
The choice is yours.

1155 is simply no longer relevant. An assembly based on socket 1150 will be cheaper than in 2011. However, 2011 also has advantages. In particular, four-channel memory, 40 PCI-E lanes... In addition, 6-core processors have been developed for this socket, and soon there will probably be eight-core ones. In short, if you have money and a desire to build a more productive computer, then choose 2011. If you're on a budget and don't want to stick to top-end solutions, then go for the 1150.
Socket, that is, the processor socket determines the type of processor that can be installed on the motherboard. Most often, changing the processor to a new generation unit is also associated with changing the motherboard, although, of course, this does not always have to be associated with such an expensive step. 
This is an old stand designed for second generation processors. (Sandy Bridge) and third generation processors (Ivy Bridge). It replaced the used LGA1156 socket, with which it is not compatible. In relation to the older one, the new stand has one less pin. The motherboard chipsets also changed, which were labeled P67 and H67, with only the second version allowing the use of integrated graphics.
The differences between the two main systems are as follows:
In addition, the H67 and P67 chips are:
- increased DMI bus bandwidth 2.5 GB/s
- PCI Express 2.0 support.
- SATA 6 Gbps support for two drives
LGA 1150
This latest stand is aimed at future owners of fourth-generation Intel Haswell processors. The two main motherboard chipsets are Z87 and H87. As with the previous generation of LGA1150 sockets, they are not compatible with older sockets. The difference in design is, first of all, the smaller number of contacts (5 less). Compared to previous chipsets, Z87 introduces several changes, such as:
- support 4 USB 3.0 ports
- support for SATA 6 Gb/s standard
At the beginning of 2015, the following chipsets appeared on the market: H97 and Z97, which should provide support for future fifth-generation processors (Intel Broadwell), and also support SATA Express and Thunderbolt.
Which is better 1155 or 1150?
The answer to this question is not clear-cut. Yes, it really depends on the processor itself. The LGA1150 is not a new or upcoming stand, but it is sufficient for many applications, especially when you have less money to spend. Before making a decision, you should first choose a processor, and only then look for a suitable motherboard.
Sandy Bridge processors with LGA1155 first appeared in 2010, replacing not the most successful processors with the LGA1156 socket and Lynnfield core. The new processors had greater performance and at the same time ran noticeably less hot. Models with an unlocked multiplier made it possible to achieve record frequencies at the time of release. In 2012, processors with the Ivy Bridge core were released, using the same LGA1155 processor socket. These chips belong to the third generation and differ primarily in their support for PCI-E version 3.0. Thanks to this, those who support them gained popularity just as quickly as Sandy Bridge. Video card manufacturers also contributed to this by releasing top solutions with such an interface. For the sake of objectivity, it is worth noting that third-generation processors had less overclocking potential compared to the second generation.

Socket LGA1155
Fourth generation processors, Haswell, replaced Ivy Bridge. They brought with them not only a new level of performance, but also a new processor socket. The graphics built into the processor have undergone serious modernization, and the performance has reached values that allow you to play simple games quite comfortably. Almost simultaneously with the fourth generation, fifth-generation processors with the Broadwell core were released, which provide performance similar to Haswell with lower power consumption.
The table below allows you to compare the listed processors:
| Characteristics | LGA1155 | LGA1150 | |||
| CPU core | Sandy Bridge | Ivy Bridge | Haswell | Broadwell | |
| Clock frequencies, MHz | 1400-3800 | 3100-3800 | 2000-3500 | 2800-3300 | |
| PCI Express support (version) | 2.0 | 3.0 | 3.0 | 3.0 | |
| External L2/L3 cache size, KB | 6144-8192 | 6144-8192 | 6144-8192 | 4096-6144 | |

To compare chipsets that support these processors, let's take older models whose names begin with "Z"
| Characteristics | LGA1155 | LGA1150 | |||
| Chipset | Z68 | Z77 | Z87 | Z97 | |
| Maximum number of PCI Express slots | 8 slots using up to 8 PCI-E 2.0 lanes | 8 slots using up to 8 PCI-E 2.0 lanes | 8 slots using up to 8 PCI-E 2.0 lanes | ||
| Number of USB ports | 14 | 10 | 14 | 14 | |
| USB 3.0 support | No | 4 ports | 6 ports | 6 ports | |
| SerialATA support | 2 SATA 6Gb/s channels + 4 SATA 300 channels | 6 channels SATA 6Gb/s | 6 SATA 6Gb/s channels or 4 SATA 6Gb/s channels and 1 M.2 connector | ||
| SSD caching technology | Intel Smart Response Technology | Intel Smart Response Technology | Intel Smart Response Technology | ||
To compare performance, consider 3 older processors of the second, third and fourth generations. The fifth generation does not make much sense to consider, since these CPUs are not created for high performance, but to improve performance per watt. Therefore, they are inferior in performance to fourth generation processors.
| 2700K | 3770K | 4790K | |
| FutureMark 3DMark Vantage Performance CPU | 24037 points | 26338 points | 31170 points |
| Cinebench R11.5 SMP Rendering Benchmark | 6.97 points | 7.57 points | 9.09 points |
| 104.51 FPS | 104.38 FPS | 104.71 FPS | |
| 7-Zip 9.13b x64 CPU Benchmark Performance test | 19989 points | 21828 points | 24270 points |

| Intel Linpack x64 Solving a system of 10,000 equations | 40.8741 Gflop/sec | 49.8957 Gflop/sec | 54.1917 Gflop/sec |
The test results show how processor performance has increased from generation to generation. 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 core, and the main performance criterion is the clock speed. It can be seen that the Core i7-3770, as having the lowest clock frequency, showed minimal performance. All old games behave this way, so if you love World of Tanks or Crysis, then changing a second or third generation processor is pointless. For modern games such as GTA 5, The Witcher 3 or Project CARS, a newer processor will provide better performance. For tasks such as photo and video editing, mathematical calculations, etc., switching from to makes sense. Especially considering that modernization will require replacement only and. The remaining components can be used from the old system.
Let's turn to energy consumption. Let's consider the Core i7-2700K, Core i7-3770K, Core i7-4790K processors installed in a system where the second noticeable energy consumer is the Radeon HD 7970 video card. The load on the processor was provided by a performance test built into the 7z archiver and capable of loading all processor cores in system
The power consumption of the processor determines its heating. Those. The more the processor consumes, the better it needs to be cooled. Accordingly, the cooling system of a more economical processor, all other things being equal, will be quieter. The table with power consumption tests shows that the second generation Core processors have the highest power consumption. With third and fourth generation processors, things are a little more complicated. The tested processors showed a funny result: the Core i7-4790K was better at idle, and the Core i7-3770K was better under load. However, it is worth considering that modern processors rarely work at full load, so it is important that the CPU is able to effectively reduce power consumption. Based on this, it can be argued that in non-extreme operating modes the Core i7-4790K will have lower power consumption.
