▷ Intel socket 1155 processors: all the information? ? sandy bridge

Also known as Socket H2, it was a socket that succeeded the LGA 1156 in a formidable way because we began to see a domestic performance that we had always dreamed of. socket 1155 was a socket dedicated to home computers, there being a wide range of processors that solved the needs of consumers, as well as companies.

You can not miss everything that comes next because this socket is so legendary that it is still used today.

2011 Sandy Bridge led the way

After several back architectures, Intel decided to release a second generation of its famous Core i3, Core i5 and Core i7. We say second because the first generation of these came with Nehalem. Historically, this is January 2011, and Westmere is a thing of the past, so Intel emphasizes CPU and GPU optimization .

Sandy Bridge was a range that would be focused on all desktops, laptops and servers. However, in November of this same year, Intel would release its 2011 LGA (Socket R) to cover all the needs of the servers, with incredible Xeon E3. We also saw the Intel Pentium and Celeron in low ranges for 1155.

Socket 1155 was named this way because it contained 1155 pins that made contact with the processor. That said, the Sandy Bridge family would be built at 32nm and would come with the first integrated graphics cards: HD Graphics, HD Graphics 2000, HD Graphics 3000, HD Graphics P3000. This second generation would have the following ranges of processors.

Their motherboards were the H61 (compatible with Ivy), B65, Q65, Q67, H67 (compatible with Ivy), P67 (OC and compatible with Ivy) and Z68 (OC and compatible with Ivy). Removing the H61, we could all install up to 32 GB of DDR3 RAM. Although the speed was limited to 1333 MHz, we could use memories with higher speeds.

Before I forget it! All Sandy Bridge desktop processors that were compatible with LGA 2011 and 1155 supported PCIe 2.0 and DMI ( Direct Media Interface ) 2.0.

Intel Core i7

In turn, the Core i7 Extreme range still existed , although it would have to wait 1 more year for the 3970X. On the other hand, we had 6 Core i7 with different frequencies, which ranged from 2.8 GHz to 3.6 GHz. At least 4 cores and 8 threads came, but they could reach 6 cores and 12 threads at the top of the range.

They were all turbocharged, DDR3 RAM compliant, had 8MB / 10MB / 12MB / 15MB L3 cache and a TDP ranging from 65W to 150W in the Extreme range. We started to see the ending in "K", which meant that the processor was unlocked to overclock . We continue to see this nomenclature on current Intel processors.

People who wanted a very high-performance processor that could be "fiddled with, " opted for a 2700K, a 2600K, or a later 3930K, which came out in 2012. On the other hand, from the 3820 to the 3970X, certain i7s were compatible with LGAs. 2011, being able to take advantage of the benefits of this great socket, such as the quad channel DDR3 at 1600 M Hz, while the normal ones were compatible with the Dual Channel at 1333 MHz.

As for the prices of these i7, they started from $ 300 and the Extreme range reached $ 1000. These i7s were focused for enthusiasts.

Intel Core i5

We come to one of the best ranges ever made, the second generation of i5. Intel oriented this family to pure and hard gamers , offering a K for those who wanted to get the most out of the processor. In this sense, all processors had 4 cores and 4 threads, which ranged from 2.5 GHz to 3.4 GHz frequencies.

Like the i7s, they had Turbo Boost, which could push them up to 3.8 GHz. They all had dual channel DDR3-1333 MHz technology and were a complete success, especially its 2500K, which is still in use today. It was a processor that offered very good performance, but did not reach the benefits of the highest i7. It would have been nice if the "Ks" were compatible with 1600 MHz.

While the i7s were purchased by enthusiasts and professionals, the i5s went to many homes with the goal of entertaining themselves with video games. And it was to think about it, since the 2500K cost $ 216 and the 2700K $ 332. They were more than € 100 of difference, when, apart, you had to add a good graph.

Intel Core i3

Removing the 2115C, which was the only i3 compatible with the BGA 1284 socket, all the others went straight to socket 1155. These mid-range processors were consolidated at a fairly good price, as they incorporated 2 cores and 4 threads for $ 138.

Compared to its siblings, its TDP was much lower, reaching 35W, although there was an i5 (2390T) that had the same TDP. The i3s came out on the market in a rampant or unbalanced way, as some came out at the beginning of the year, like others at the end.

Here, there were no “K” models because they were mid-range processors focused on efficiency. Anyway, having 2 cores performing at 3.5 GHz is not bad at all.

Finally, they were compatible with the dual channel DDR3-1333.

Xeon E3

Although many think that in that year the best for servers was LGA 2011, it would be necessary to wait until November or even 2012. So, what was Intel doing with the range of servers until LGA 2011?

We saw the solution in April and May of the same year, with the output of the 12 Xeon E3 for socket 1155, as 2 for BGA 1284. As far as we are concerned, we had processors that ranged from 2 cores to 4, going from 4 threads up to 8.

They worked with DMI 2.0 and PCie 2.0, they had a TDP that did not reach 100W and their cost was quite interesting, since it did not reach $ 900. In this way, many companies considered buying i7 for servers in this same socket, since they got a little more performance in the higher ranges. However, the Xeon's safety and credit were guaranteed.

On your 1290, we could see up to 4.0 GHz on turbo, but they were all Dual Channel 1333 MHz compatible , leaving the 2 Xeon compatible with BGA 1284 with Dual Channel 1600 MHz compatibility .

Finally, we would like to highlight the appearance of the Pentium 350 as a server solution. Logically, they could not be servers with high needs because it incorporated 2 cores and 4 threads that operated at 1.2 GHz.

2012, Ivy Bridge was the last consignment for socket 1155

The third generation of i3, i5 and i7 processors began manufacturing in late 2011, but we would have to wait until 2012 to see their releases. It must be said that the Ivy processors were compatible with the Sandy platform, since they shared socket 1155, as socket 2011. In order for this to be feasible, the motherboards would have to update their BIOS.

All of Ivy's processors were made at 22nm and we were starting to see support for 4K, DDR3L, speeds of 2800 MT / s in RAM, Intel Quick Sync Video or the compatibility of Intel graphics with DirectX 11, OpenGL 4 and OpenlGL 1.1. Highlight the Tri-Gate transistors that managed to cut consumption in half.

Their motherboards were: B75, Q75, Q77, H77, Z75 (OC), Z77 (OC). The last two chipsets were recommended for " K " processors.

Intel again released several Xeon Ivy Bridge for LGA 1155, but the usability of LGA 2011 for this purpose was evident, obtaining better performance. That said, 2012 was marked by the emergence of USB 3.0, such as PCIe 3.0. Also, we saw Intel Clear Video Technology embedded in all chipsets.

On the other hand, in desktop processors, Intel continued to maintain the Celeron and Pentium range, attributing them the technologies of its older brothers, although the PCIe was still 2.0.

Admittedly, CPU performance increased a bit, but this was not the reason why users switched from Sandy to Ivy, but rather that new supports and new compatibilities were the essential argument. In the graphic section, we did see a spectacular advance from one year to the next.

Doing some offtopic , we think about the year of the launch of Windows 8, so the video game industry was in luck, but it is true that Windows would release its best version the following year, in 2013.

Finally, to say that the Ivy Bridge processors had temperature problems when overclocked, giving 10 degrees more than the Sandy ones. Apparently, the problem was with the thermal paste between the chip and the heatsink. Intel received much criticism for this poor thermal conductivity, although it was solved by changing the thermal paste.

Intel Core i7

In this aspect, the 3770K obtained great relevance, which incorporated 4 cores and 8 threads with a frequency of 3.5 GHz expandable to 3.9 GHz. The TDP was lowered to 77 W and the price was maintained. Now they did support dual channel DDR3 1600MHz.

The Core i7 Extreme range was reduced to a single processor, the 4960X, whose specifications were: 6 cores and 12 threads, 3.6 GHz expandable to 4.0 GHz, 130 W TDP, 15MB Cache L3 and Dual Channel 1866 MHz compatibility. Unfortunately, it would end up on the LGA 2011 socket, so it did not work for socket 1155.

Removing 3 processors (4960X, 4930K, and 4820K), they all incorporated Intel HD 4000 graphics. This range was narrowed down to enthusiastic people who wanted "the best of the best" to play. Despite their criticism, these models were overwhelmingly successful, without any competition.

The prices of the 3770K remained at $ 330 (although it was seen at € 270), while the 2011 LGA models ranged from $ 300 to $ 1000.

Intel Core i5

He gained incredible fame because his serial performance was brutal, which we could make even more of if we overclocked. This time, they would all have dual channel DDR3-1600 support, as with PCIe 3.0. What's more, there was an i5 dual core (3470T), which did not end up having a good acceptance because its price was practically identical to a quad core. The difference was energy consumption.

The 6 MB of L3 cache became almost a standard, but Intel did its thing again, releasing Ivy Bridge processors in both 2012 and 2013. In addition, there was almost no news between each other, since they had very specific specifications. alike. The only thing that improved was the energy optimization that came with the “S” range.

As for the 3570K, it had a starting price of $ 225, but here we used to see it for € 249.

Intel Core i3

The 2013 iMac incorporated the i3-3225

Going back to Intel's mid-range, Ivy's Core i3s were more concrete, but contained certain improvements. Intel was refocusing on offering the maximum optimization between energy efficiency and performance. Most came out in 2012, but in 2013 they kept releasing Core i3.

The same cores and threads were kept: 2 and 4. Regarding the frequencies, they were improved, ranging from 2.8 GHz to 3.5 GHz without turbo. Unfortunately, they continued with PCIe 2.0, although they did support dual channel at 1600 MHz. Clearly, Intel left these processors for minor demands, such as multimedia or office use.

In this case, we're very interested in Intel's graphics integration. In this sense, the HD 4000 were only integrated in the i3 3245 and 3225.

Xeon E3

Finally, we have the server processors, which all came out on the 14th of May 2012 for socket 1155. The rest were released for the BGA 1284, LGA 1356 and LGA 2011 sockets between 2013 and 2014.

Regarding the Xeon, the same cores and threads were maintained, but it was updated to Dual Channel 1600 MHz, and PCIe 3.0. In addition, they improved their energy efficiency, such as base frequencies. While in Sandy we saw some 2.2 GHz or 2.4 GHz processor; at Ivy, the lowest was 2.3 GHz. On the other hand, the turbo frequency increased from 4.0 GHz to 4.1 GHz.

Intel was releasing a model with 2 cores and 4 threads, whose turbo was able to go higher than 1 GHz because it had 2.3 GHz of base frequency, but in turbo mode it went to 3.5 GHz. We had 3mb L3 cache again in this version, like in Sandy. At Ivy there was no Pentium for servers.

In 2012, they realized the limitations of socket 1155 in the server field, prompting Intel to focus this branch on socket LGA 2011, which eventually evolved into LGA 2011-1 or 2011-3.

2013-2015, the end of socket 1155

It was one of the longest-lasting sockets on the market because Intel released them in 2011 and they lasted until 2015. In fact, many people still use its technology today. It was a glorious time for Intel in which it had successes in all fields: laptops, servers and desktops.

His path would end in 2015, with the departure of LGA 1150 (Socket H3), another of the best sockets in history. This new socket would come from the Haswell, Haswell - WS and Broadwell processor families.

We recommend the best processors on the market
