Intel lga 775: history, models and uses in 2019 ✅✅

The LGA 775 is a socket that marked history in the early 21st century. We have done a review and we tell you all its history, models and uses.

Known as Socket T, Intel formed a legend around a socket that would give unique moments to many: the LGA 775 socket. Thanks to the existence of this we could see anthological processors, which you will see below. With this socket began a fabulous era that would be called PC Master Race because, what was once called a computer, would end up being a beastly entertainment and performance platform.

For this reason, we have compiled all the information necessary to review its history, its models, and the uses we find today.

Let's get started!

Early 2000s, precedents

To start telling your story, we are going to give some context to situate ourselves at that time with precision. We are in about 2000 marked by socket 478, a socket that would give life to Pentium 4 and Celeron. This socket replaced the 423, whose performance was not entirely good. Therefore, it was short-lived in the market.

We would be in 2000 when we saw the first Willamette , but the good one was the Northwood , that is, the Pentium 4 of socket 478.

The Northwood (project name Pentium 4s) came out in January 2002 at speeds of 1.6 GHz, 1.8 GHz, 2 GHz, and 2.2 GHz. It was a good jump, but the best was yet to come. Of course, we would have to wait for 2004.

Year 2004, the beginning

Although we have not been able to find a specific date for Intel to remove this socket, we have been able to observe the output of certain processors compatible with LGA 775. The first time we saw Socket T was in the early 2000s, specifically the summer of 2004.

That same summer, we saw two processors compatible with this socket come out: Intel Celeron and Pentium 4 Gallatin or Extreme Edition. I know some of you will say "That one came out in 2003!" Which is true, but in the summer of 2004 they released a version that would use the 775.

We were facing one of the most notable performance advances, since it was a processor that worked at 3.4 GHz, compared to the 2.2 GHz of Northwood . Remember that these processors had two cores; it had gone from 800 MT / s to 1066 MT / s in the bus speed.

Although Xeon existed since 1998 ( Drake ), the role was taken by the Pentium 4. On the other hand, we also know that many of you know the LGA 775 by the Intel Xeon, but we will explain that later.

Later, we would see that this version of the Pentium 4 would be migrated to the Prescott 2M core, because Prescott had existed since February of this year. This summed up at 3.73 GHz and 64-bit application compatibility.

Year 2005, Prescott 2M and Cedar Mill

This would be the year in which we would see the most notable computer advances of this century. Thanks to the performance offered by the two cores and the DDR2 RAM memory, a barbarous performance was achieved. So, from here the LGA 775 began to take center stage.

Prescott 2M

A year later, Intel released a new core called "Prescott 2M", closely related to Irwindale , a derivation of the Xeon name. It was characterized by Intel 64 bit, EIST, Tm2 and the 2mb L2 cache. However, Prescott 2M processors would incorporate Hyper-Threading, a technology that was incorporated in the 2002 Xeon.

Hyper-Threading sought to accelerate the speed of multi-threaded processes used by certain programs, such as video rendering. Unfortunately, this family would last only 1 year because Cedar Mill would come in 2006 to replace it and reduce the high TDP of the old series.

Before we got fully into 2006, say that Intel had 3 technologies per banner: Intel 64, Hyper-Treading and Virtualization Technology. It must be said that both Prescott and Cedar used LGA 775 as a socket.

2006, Conroe, Allendale and LGA 775

We would have to wait until July 27, 2006 to see the series of processors that would change the rules of the game: Intel Core 2 Duo, a range priced at $ 183 and $ 224. They were made at 65nm, focused on desktop computers and replaced the Pentium 4s. Just 2 days later, they released the Core 2 Extreme range.

The Conroe family offered 40% more performance compared to Pentium 4 and came with 4mb of L2 cache, although the E6300 and E6400 versions stayed in 2mb of L2 cache due to problems in the manufacturing process. Intel also released Allendale , a family of low- cost processors whose performance and size was smaller.

Allendale and Conroe (except Conroe-CL, which equipped LGA 771) had the LGA 775 as a socket, be it an Intel Xeon, Core 2 Duo / Extreme, Pentium Dual-Core or Celeron. The mythical processor locking lever that we see today appeared, which we operated to open the socket, place the processor and lock it.

Regarding Intel Xeon, its dual-core version would be released at the end of September 2006: the 3000 series. Interestingly, they did not support Hyper-Threading, but it was capable of running at 1066 MHz, having a TDP of 65W, and ranging from 1.86 GHz to 3.00 GHz frequency. Following up with Xeon, their 3100 series would also use Socket T, but, starting with Woodcrest , they would switch to LGA 771.

2008 Wolfdale, Yorkfield and Nehalem

This year it starred the names of Wolfdale and Yorkfield, two families that would house the LGA 775 until 2011. We reached the end of the life of this magnificent socket that we remember with great nostalgia.

Nehalem was born to finish a decade of anthological processors, as to give way to another decade in which Intel would dominate without mercy in the processor sector.

Wolfdale, January 20, 2008

Wolfdale would be the one who would lengthen the path of LGA 775. It is a variation of the Core 2 Duo, Celeron, Pentium and Xeon. Although Pentium and Celeron incorporated 2 mb and 1 mb of L2 cache, the Core 2 Duo reached 6 mb and 3 mb of L2 cache.

The original Wolfdale family refers to the E8000 series of the Core 2 Duo and Xeon 3100. We were going through a 45nm manufacturing process on processors that reached 3.33 GHz officially. We say this because the Core 2 Duo E8700 reached 3.5 GHz, but was never released.

Yorkfield, March 2008

This month gave way to a family that would stand out for its gross power, taking a brutal leap in performance compared to that given by the Core 2 Duo. Intel was on the high end with its two cores, but AMD was on the heels with Athlon II and Phenom II and its range of Quad Core X4 and Six Core X6 processors (colloquially called "stoves" with TDPs of up to 140W).

So Yorkfield brought the brand and Core 2 Extreme, processors that equipped 4 cores and up to 8 mb of L2 cache. We saw frequencies ranging from 2.3 GHz to 3.2 GHz, such as TDP from 65W to 136W, from the Core 2 Extreme range.

Intel accumulated ideas, having the Yorkfield and Kentsfield family at the same time. As for the Xeon range, they were the latest flips of the LGA 775 socket, as the LGA 711 was beginning to be equipped. "Unfortunately", we would not see any more Xeon with this socket.

The Nehalem microarchitecture, November 2008

First generation Intel Core i3

In late 2008, Intel released a family of processors called Nehalem, which would be a first generation riddled with news. The company would offer 3 ranges: Core i3, Core i5 and Core i7. Do they sound familiar to you?

• Core i3 would be the low-end Core i5, the mid-range Core i7 would be the high-performance range.

It was the beginning of DDR3, the 12 MB of L3 cache and a host of new technologies that would speak. On the other hand, these processors would not be released until 2009.

2011, the end of LGA 775

As we have not found a truthful information that affirmed that the end of LGA 775 occurred with the departure of the new Intel processors, we assume that it would end in 2011.

Although the new Intel processors were released in 2009, the Core 2 Quad family was still being sold, which meant that the LGA 775 socket was still working. In fact, in 2009, the latest Core 2 Quad was released, which would be named Q9505, a processor that operated at a frequency of 2.83 GHz, a bus speed of 1333 MHz, a TDP of 95W and was compatible with the LGA 775.

In July 2011, the Core 2 processors were withdrawn, relegated to the Nehalem architecture. We would have to wait until 2012 to see the manufacture of these processors suspended.

What happens in 2019 with the LGA 775?

Following the laws of obsolescence, we would say that this socket is obsolete and has no practical functionality today. On the contrary, in their last years, they took out motherboards that supported DDR3 RAM, so it doesn't seem crazy to recycle a computer with this technology.

A large community of users has resurrected the legendary Socket T as a low-cost gaming option. In this way, with the purchase of second-hand components, they managed to put together a PC capable of running the Witcher 3 at around 30 FPS in medium graphics. All this with a PC that does not reach € 200 !

In less demanding games, such as the GTA V, you can reach 60 fps without problems, with a simple Nvidia GTX 760.

In addition, there is a MOD with which to convert a 775 board to a 771 in order to upgrade the Intel Xeon and take advantage of the L45XX, E54XX and X54XX series.

As you can see, it is the only socket that has been rescued almost 10 years later to give it a new use. Not all stories have to have a sad ending.
