The socket 479 is an Intel® central processing unit (CPU) integration socket that allows the motherboard and CPU to work hand-in-hand to perform functions. Most sockets have a number after them to signify how many pins are on the socket and CPU, which would lead many to believe that this socket and CPU both have 479 pins, but this CPU really has 478. It is named 479 to differentiate it from the socket 478, which is used for desktop computers; the 479 connector is used for mobile platforms. Socket 478 CPUs can fit into the 479 connector, but they will not electronically configure or work with this socket.

Socket 479 is a microprocessor socket, meaning it is made for CPUs that do not fit into desktops, namely mobile computers and laptops. Created in 2001, this socket has many different microprocessors made under its design. There are the Pentium 3-M®, mobile Celeron®, Coppermine-T® and Tualatin® CPUs all made for this socket.

There are 479 pinholes in the socket 479 connector. What is odd about this socket is that, normally, CPUs have the same amount of pins as the socket, but the CPUs that fit this socket have only 478 pins. This was done to differentiate the socket from the socket 478, which was made at the same time for desktop computers. Socket 478 CPUs can fit the 479 connector, but they will not work because the electronic and pin configuration is different. The amount of pins means many CPUs made after this socket can fit the 479 connector, but they also will not work.

To tell the difference between a socket 478 and socket 479 processor — because the CPUs looks relatively the same — looking at the pin configuration will be of assistance. Both CPUs have 478 pins, but the pin configuration is different in the bottom right corner. The 478 CPUs are missing two pin spaces directly next to each other, while the 479 CPUs are missing two pin spaces diagonal to each other. This pin configuration is one reason why 478 CPUs do not work with the 479 socket.

The minimum and maximum processing speed of the socket 479 presents a wider gap than most other sockets. The low processing value is at 700 megahertz (MHz), and it can go all the way up to 2,333 MHz. The higher value was not utilized well until 2006, late in the 479 socket’s career, just before it was phased out for more advanced sockets.

Intro

Not so long ago I decided to remember the old days when overclocking was a popular activity, when Athlon processors on Socket A (462) were not overclocked only by the lazy . .. Well, many years later, retroclockers set new records on old systems, waging battle for every megahertz. More about this in my review on the Personal Pages «Modern Socket-A Wars».

And in this article we will return to the end of 2001, when the first processors based on Socket 478 were announced, we will briefly talk about the evolution of socket 478 and dwell on modern overclocking of Pentium 4 family models. I think, for those overclockers who did not catch those times , this material will be interesting, and experienced enthusiasts will wipe away a mean tear, remembering Northwood and Prescott.

Probably, those readers who closely follow the world of extreme overclocking have already guessed that we will talk about one of the stages of the Old School is Best School retro championship. I took part in it.

A bit of history

If you remember the history, Socket 478 was a logical continuation of Socket 423, on which the first Pentium 4 appeared, which was fundamentally different from the previous Pentium III on Socket 370. Pentium 4 processors introduced a new microarchitecture, whose name – NetBurst.

This architecture was characterized by high clock speeds and hyperpipelining. The Pentium III froze at 1.4 GHz, the very first Pentium 4 models based on the Willamette core started at 1.3 GHz and stopped at 3.4 GHz on the Northwood and Prescott cores (known as a «stove» in the overclocking environment), and all this thanks to the NetBurst microarchitecture .

But what did hyper-threading bring to the Pentium 4? To put it simply, «thoughtfulness». It was all about the length of the unpredicted transition pipeline, which was noticeably longer than the Pentium III.

Pentium III models had a pipeline length of 10 stages, Pentium M (Socket 479) models had 12 stages, and Pentium 4 generations had 20 to 30 stages. In short, the shorter the pipeline, the faster the processor gets the result of the calculation, so the overclocked older versions of the Pentium III overtook the first Pentium 4 models.

But progress did not stand still, and after the Pentium 4 based on the Willamette core, Intel introduced the new Northwood core, which enthusiasts liked so much later. Processors based on this core were produced from 2002 to 2004 and overclocked perfectly on FSB. In addition, they were fast and moderately cold.

In 2004 they were replaced by Pentium 4 based on the new Prescott core. Processors of the Prescott family were distinguished by a significantly increased heat dissipation, for which they were called «stoves», and an increased conveyor length. The positive side of the new core was the presence of new SSE3 instructions, a thinner manufacturing process and twice the size of the second level cache. In those days, there were ongoing discussions on the forums, which is better — Northwood or Prescott?

To refresh my memory, I would recommend reading an article on the subject: «Northwood (2.8C) vs. Prescott». If you’re not curious enough to click the link, here’s a short recap: Northwood won where no SSE3 instructions were used, was cooler and faster with a shorter pipeline, but lagged behind in terms of frequency potential in terms of overclocking.

In addition to Pentium 4 based on Willamette, Northwood and Prescott cores, for the first time Intel has introduced a special cast of Extreme Edition processors with a price tag of $999. These CPU models contained another core — Gallatin, which belongs to the server segment, but for wealthy enthusiasts who are ready to part with the above amount, Intel did not spare either a free multiplier or 2 MB of L2 cache. Two versions of the Pentium 4 Extreme Edition were released on Socket 478 — 3.2 GHz and 3.4 GHz. However, the Gallatin core was an improved version of Northwood used in Intel Xeon server solutions.

Let’s take a look at Socket 479or mPGA479M. This connector is designed for mobile processors from Intel. Although Socket 479 does indeed have 479 pins, processors designed for it use only 478.

Many people confuse it with Socket M, which physically resembles Socket 479 in the same number of pins, but they are not electrically compatible.

Socket 479 includes processors based on Banias and Dothan cores. The architecture of these cores is closer to the Pentium III than to the Pentium 4. Dothan-based processors received a short pipeline, high performance per clock, minimal power consumption, a lot of architectural improvements aimed at increasing performance and a large amount of L3 cache (2 MB) . Such CPUs often brought any Pentium 4 to its knees. The older Dothan model with the Intel Pentium M 780 index worked at a frequency of 2267 MHz, while the thermal package was only 27 watts. For comparison, the top Pentium 4 Northwood and Prescott models were limited to TDP 89Tue

But back to Socket 479. Despite the fact that it belonged to the mobile segment, a number of motherboard manufacturers (such as AOpen and DFI) introduced desktop versions of motherboards with socket 479. And ASUS, being a leading manufacturer of computer components, decided distinguished itself and introduced the ASUS CT-479 processor adapter, which allowed installing Intel Pentium M processors in a number of Socket 478 motherboards of its own production.

Battle for Socket 478/479

Now let’s talk about the battle for the title of Socket 478/479 leader. For the second year in a row, the leading overclocking portal HWBOT.org has been organizing a retro competition called Old School is Best School. The main idea of ​​such competitions is to remember the basics and subtleties of overclocking computer components that have long been discontinued. The organizers come up with new tasks every time, and enthusiasts from all over the world compete with each other for the title of the best retroclocker.

These competitions do not require large financial costs and anyone can take part in them, just register on the HWBOT.org website and start completing tasks. All competitions are held on a special OC-Esports site, where all results are collected and points are awarded. Each Old School is Best School championship consists of five stages, which in turn are dedicated to a particular processor socket and include several tasks.

Not so long ago, the fourth stage of the second season of the Old School is Best School championship, which was entirely devoted to Socket 478/479, ended, as well as video cards of the ATI Radeon 9000 line. The tasks were as follows: calculating the number of pi in the SuperPI 1M test using any of the platforms to choose from (Socket 478 or Socket 479), and obtaining the best result in the 3DMark 2003 test package on the same platform with ATI Radeon 9000.

As a rule, after the start of the competition there is a buildup, someone is already making the first overclocking attempts, someone is looking for the right hardware at flea markets. There is also a third party that always watches what is happening and at the very end, a couple of minutes before the end of the competition, lays out its result. We will skip these, in my opinion, not the most interesting category of overclockers, but we can stop at the first two.

The entire championship is similar to a game of poker, since each player has several worked out results, but is laid out at the beginning, as a rule, the most modest with the minimum number of points. At the sight of such indicators, opponents post a slightly better result, and it turns out to be a kind of race until one of the participants stops due to the exhaustion of the processor resource, or the need to change the cooling system. An important role in achieving the first positions is played by tuning the operating system, setting up drivers, memory timings and other tricks. Often what you see in a screenshot of a competitor can give you food for further thought on how to competently prepare a test bench for a new stage of the race, all this is vaguely reminiscent of Formula 1.

But this time this chronology of events was violated by the Ukrainian team Overclockers.UA represented by RomanLV , who on the third day of the competition immediately took and posted a very serious result in the Super Pi 1M test — 26 sec 391 msec. When using air cooling, the overclocker overclocked his Pentium M 740 on the Dothan core to 2753 MHz, or 58.9%. Naturally, this became possible thanks to the ASUS CT-479 adapter and the ASUS P4P800 SE motherboard. Finding such an adapter is not an easy task, and not every team will be able to purchase and test it in action in a period of one month. Well, a kind of countdown was set.

And the day before this event, the Czech HardOCzech Team, represented by an enthusiast under the nickname havli , gets a result of 29 sec 439 msec using a Pentium M 770 running at 2615 MHz. Overclocking, carried out with the help of air cooling, amounted to 22.6%. The motherboard was ASUS P4P800 Deluxe.

Greek overclocker Stelaras from the HwBox Hellas O/C Team achieved 26 sec 478 ms by overclocking a Pentium M 760 to 2700 MHz in air.

Processor sockets: generations in pictures

Socket (colloquial — socket) of the central processor is a socket located on the motherboard of the computer to which the central processor is connected. The processor, before it is installed in the motherboard, must match its socket. It is very easy to figure out what a processor socket is, if you remember that the latter is a microcircuit, only of a relatively large size. The socket is located on the motherboard, outwardly it looks like a low rectangular structure with many holes, the number of which corresponds to the legs of the processor. A mechanical latch of a special design is used to securely fix the inserted microcircuit in the socket. Note that Intel, unlike AMD, has recently been using a different principle for connecting the processor and the board. Sometimes forums ask which socket to choose. In fact, you should first select a processor, and already under it — a board with the appropriate socket. However, one important point must be taken into account. Intel is «famous» for the fact that often each new generation of processors involves the use of a new socket. This can lead to the fact that a recently purchased computer based on the processor of this company will be difficult to upgrade in a few years due to the incompatibility of the installed microprocessor and the new ones offered on the market. AMD has a more loyal attitude towards customers: changing sockets is slower, and backward compatibility is usually maintained. Although, times are changing.

It is with him that the era of Intel processors separation into inexpensive Celeron solutions with a cropped cache and Pentium — more expensive full versions of the company’s product begins. The connector was installed on motherboards with a system bus from 60 to 133 MHz. The socket is made in the form of a square plastic movable box; when installing a processor with 370 pins, a special plastic lever pressed the processor legs to the connector pins. Supported Intel Celeron Coppermine, Intel Celeron Tualatin, Intel Celeron Mendocino, Intel Pentium Tualatin, Intel Pentium Coppermine processors. The speed characteristics of installed processors are from 300 to 1400 MHz. Supported third-party processors. Produced since 1999 years. Socket 423 — the first socket for Pentium 4 processors. It had a 423-pin grid of legs and was used on personal computer motherboards. It lasted less than a year, due to the impossibility of the processor to further increase in frequency, the processor could not pass the frequency of 2 GHz. Replaced by Socket 478. Launched in 2000.

The connector supports Intel solutions — Intel Pentium 4, Intel Celeron, Celeron D, Intel Pentium 4 Extreme Edition. Speed ​​characteristics from 1400 MHz to 3.4 GHz. Produced since 2000. Type Purpose Number of contacts Year of manufacture Socket 604 / S1 Intel 486 238 2002 Socket 754 Athlon 64, Sempron, Turion 64 754 2003 Socket 940 Opteron 2, Athon 64FX 940 2003 Socket 479 / mPGA479M Pentium M, Celeron M, Via C7-M 479 2003 Socket 478v2 / mPGA478C Pentium4, Pentium Mobile, Celeron, Core 478 2003 Socket 754 was designed specifically for the Athlon 64 model processor. The release of new processor sockets was associated with the need to replace the Athlon XP processor line, which was based on Socket A. dimensions 4 by 4 centimeters. This need was dictated by the fact that Athlon 64 processors had a new bus and integrated memory controllers. The voltage output by this socket was 1.5 volts. Of course, 754 became an intermediate stage in the development of Athlon 64. The high cost and initial scarcity of these processors did not make this platform very popular. And by the time when the availability and cost of components had just returned to normal, AMD presented the release of a new socket — Socket 939. By the way, it was he who helped make the Athlon 64 a popular and really affordable processor. Type Purpose Number of contacts Year of manufacture Socket 939 Intel 486 939 2004 LGA 775 / Socket T Pentium4, Celeron D, Core 2, Xeon 775 2004 Socket 563 / Socket A / Compact Mobile Athon XP-M 563 2004 Socket M / mPGA478MT Celeron, Core, Core 2 478 2006 LGA771 / Socket J Xeon 771 2006 Socket 775 or Socket T — the first socket for Intel processors without sockets, made in a square form factor with protruding contacts. The processor was installed on the protruding contacts, the pressure plate was lowered, and with the help of a lever it was pressed against the contacts. It is still used in many personal computers. Designed to work with almost all fourth-generation Intel processors — Pentium 4, Pentium 4 Extreme Edition, Celeron D, Pentium Dual-Core, Pentium D, Core 2 Quad, Core 2 Duo and Xeon series processors. Produced since 2004. The speed characteristics of the installed processors are from 1400 MHz to 3800 MHz. Socket A. This socket, known as Socket 462, is a socket for processors from Athlon Thunderbird models to Athlon XP/MP 3200+ models, as well as AMD processors such as Sempron and Duron. The design is made in the form of a ZIF socket with 453 working contacts (9 contacts are blocked, but despite this, the number 462 is used in the name). The system bus for Sempron, XP Athlon has a frequency of 133 MHz, 166 MHz and 200 MHz. The mass of coolers for Socket A, recommended by AMD, should not exceed 300 grams. The use of heavier coolers (coolers) can lead to mechanical damage and even lead to failure of the processor power system. Processors with a frequency of 600 MHz (for example, Duron) and up to 2300 MHz (meaning the Athlon XP 3400+, which was never sold) are supported. Socket 939, containing 939 pins of extremely small diameter, making them quite soft. This is a «simplified» version of the previous Socket 940, commonly used in high performance computers and servers. The absence of one hole in the socket made it impossible to install more expensive processors into it. This connector was considered very successful for its time, as it combined good features, dual-channel memory access and low cost, both the socket itself and the controller in computer motherboards. These connectors were used for computers with conventional DDR memory. Immediately after the transition to DDR2 memory, they became obsolete and gave way to AM2 connectors. The next step is the invention of the new DDR3 memory and the new AM2+ and AM3 sockets for the following quad-core processors from AMD. Type Purpose Number of contacts Year of manufacture Socket S1 Athon Mobile, Sempron, Turion 64/X2 638 2006 Socket AM2 / AM2+ Athon 64/FX/FX2, Sempron, Phenom 940 2007 Socket F / Socket L / Socket 1207FX Athon 64FX, Opteron 1207 2006 Socket / LGA 1366 Core i7, Xeon 1366 2008 rPGA988A / Socket Q1 Core i3/i5/i7, Pentium, Celeron 988 2009 Socket LGA 1366 — Made in 1366 contact form, in production since 2008. Supports Intel processors — Core i7 9xx series, Xeon 35xx to 56xx series, Celeron P1053. Speed ​​characteristics from 1600 MHz to 3500 MHz. Core i7 and Xeon (35xx, 36xx, 55xx, 56xx series) with integrated 3-channel memory controller and QuickPath connection. Socket T and Socket J replacement (2008) Socket AM2 (Socket M2), developed by AMD for some types of desktop processors (Athlon-LE, Athlon 64, Athlon 64 FX, Athlon 64 X2, Sempron-LE and Sempron, Phenom X4 and Phenom X3, Opteron). It replaced Socket 939 and 754. Despite the fact that Socket M2 has 940 pins, this socket is not compatible with Socket 940, since the older version of Socket 940 cannot support dual-channel DDR2 memory. The first processors supporting Socket AM2 were single-core Orleans (or 64th Athlon) and Manila (Sempron), some dual-core Windsor (for example, Athlon 64, X2 FX) and Brisbane (AthlonX2 and Athlon 64X2). In addition, Socket AM2 includes Socket F for servers and a Socket S1 variant for various mobile computers. Socket AM2+ is absolutely identical in appearance to the previous one, the difference lies only in the support of processors with Agena and Toliman cores. Type Purpose Number of contacts Year of manufacture Socket AM3 AMD Phenom, athlon, Sempron 941 2009 Socket G/989 / rPGA G1/G2 989 2009 Socket h2 / LGA1156/a/b/n Core i3/i5/i7, Pentium, Celeron, Xeon 1156 2009 Socket G34 / LGA 1944 Opteron 6000 Series 1944 2010 Socket C32 Opteron 4000 series 1207 2010 LGA Socket 1156 — Made with 1156 protruding pins. Produced since 2009. Designed for modern Intel processors for personal computers. Speed ​​characteristics from 2.1 GHz and above. Type Purpose Number of contacts Year of manufacture LGA 1248 Intel Itanium 9300/9600 1248 2010 Socket LS / LGA 1567 Intel Xeon 6500/7500 1567 2010 Socket h3 / LGA 1155 Intel Sandy Bridge, Ivy Bridge 1155 2011 LGA 2011 / Socket R Intel Core i7, Xeon 2011 2011 Socket G2 / rPGA988B Intel Core i3/i5/i7 988 2011 Socket LGA 1155 or Socket H2 — designed to replace socket LGA 1156. Supports the latest Sandy Bridge processor and the future Ivy Bridge. The connector is made in 1155 pin design. Produced since 2011. Speed ​​characteristics up to 20 GB / s. Socket R (LGA2011) — Core i7 and Xeon with integrated quad-channel memory controller and two QuickPath connections. Replacement Socket B (LGA1366) Type Purpose Number of contacts Year of manufacture Socket FM1 AMD Liano/Athlon3 905 2011 Socket AM3 AMD Phenom/Athlon/Semron 941 2011 Socket AM3+ Amd Phenom 2 Athlon 2 / Opteron 3000 942 2011 Socket G2 / rPGA989B Intel Core i3/i5/i7, Celeron 989 2011 Socket FS1 AMD Liano / Trinity / Richard 722 2011 Socket FM1 is AMD’s platform for Llano processors and looks like a tempting proposition for those who love integrated systems. Socket AM3 is a desktop processor socket that is a further development of Socket AM2+. This connector has support for DDR3 memory, as well as faster HyperTransport bus speeds. The first processors to use this socket were Phenom II X3 710-20 and Phenom II X4 model 805.910 and 810. Socket AM3+ (Socket 942) is a modification of Socket AM3 designed for processors codenamed «Zambezi» (microarchitecture — Bulldozer). Some motherboards with socket AM3 will be able to update BIOS and use processors with socket AM3+. But when using AM3+ processors on motherboards with AM3, it may not be possible to get data from the temperature sensor on the processor. Also, the power saving mode may not work due to the lack of support for fast core voltage switching in Socket AM3. Socket AM3+ on motherboards is black while AM3 is white. The diameter of pin holes in processors with Socket AM3 + exceeds the diameter of pin holes in processors with Socket AM3 — 0.51 mm against the previous 0. 45 mm. Type Purpose Number of contacts Year of manufacture LGA 1356 / Socket B2 Intel Sandy Bridge 1356 2012 Socket FM2 AMD Trinity / athlon X2 / X4 904 2012 Socket h4 / LGA 1150 Intel Haswell / Broadwell 1150 2013 Socket G3 / rPGA 946B / 947 Intel Haswell/Broadwell 947 2013 Socket FM2 / FM2b AMD Kaveri / Godvari 906 2014 Socket h4 or LGA 1150 is a processor socket for Intel microarchitecture Haswell (and its successor Broadwell), released in 2013. LGA 1150 is designed as a replacement for LGA 1155 (Socket h3). Made using LGA (Land Grid Array) technology. It is a connector with spring-loaded or soft contacts, to which the processor is pressed using a special holder with a grip and a lever. The LGA 1150 socket has been officially confirmed to be used with the Intel Q85, Q87, H87, Z87, B85 chipsets. Mounting holes for cooling systems on sockets 1150/1155/1156 are completely identical, which means full all-round compatibility and identical order of mounting cooling systems for these sockets. Socket B2 (LGA1356) — Core i7 and Xeon with integrated tri-channel memory controller and QuickPath connections. Replacement Socket B (LGA1366) Socket FM2 — Processor socket for hybrid processors (APU) from AMD with Piledriver core architecture: Trinity and Komodo, as well as canceled Sepang and Terramar (MCM — multi-chip module). Structurally, it is a ZIF — connector with 904 pins, which is designed for installing processors in PGA-type cases. The FM2 connector was introduced in 2012, just one year after the FM1 connector. Although the FM2 socket is an evolution of the FM1 socket, it is not backwards compatible with it. Trinity processors have up to 4 cores, Komodo and Sepang server chips up to 10, and Terramar up to 20 cores. Type Purpose Number of contacts Year of manufacture LGA 2011-3 / LGA 2011 v3 Intel Haswell, haswell-EP 2011 2014 Socket AM1/FS1b AMD Athlon / Semron 721 2014 LGA 2011-3 Intel Haswell/Xeon/haswell-EP/ivy Bridge EX 2083 2014 LGA 1151 / Socket h5 Intel Skylake 1151 2015 LGA socket 1151 is an Intel processor socket that supports Skylake architecture processors. The LGA 1151 is designed as a replacement for the LGA 1150 socket (also known as Socket h4). The LGA 1151 has 1151 spring-loaded pins to make contact with the CPU pads. According to rumors and leaked Intel promotional documentation, motherboards with this connector will support DDR4 memory type. All Skylake architecture chipsets support Intel Rapid Storage Technology, Intel Clear Video Technology, and Intel Wireless Display Technology (if supported by the processor). Most motherboards support various video outputs (VGA, DVI or HDMI depending on the model). Type Purpose Number of contacts Year of manufacture LGA 2066 Socket R4 Intel Skylake-X/Kabylake-X i3/i5/i7 2066 2017 Socket TR4 AMD Ryzen Threadripper 4094 2017 Socket AM4 AMD Ryzen 3 / 5 / 7 1331 2017 LGA 2066 (Socket R4) is an Intel processor socket that supports Skylake-X and Kaby Lake-X architecture processors without an integrated graphics core. Designed as a replacement for the LGA 2011/2011-3 socket (Socket R/R3) for high-performance desktop PCs based on the Basin Falls platform (X29 chipset9), while LGA 3647 (Socket P) will replace LGA 2011-1/2011-3 (Socket R2/R3) in Skylake-EX (Xeon «Purley») based server platforms. AM4 (PGA or µOPGA1331) is a socket made by AMD for microprocessors with Zen microarchitecture (Ryzen brand) and later. The connector is of the PGA (pin grid array) type and has 1331 pins. It will be the company’s first socket to support the DDR4 memory standard and will be a single socket for both high-performance processors without an integrated video core (currently using Socket AM3+) and low-cost processors and APUs (previously using various AM / FM series sockets). Socket TR4 (Socket Ryzen Threadripper 4, also Socket SP3r2) is a socket type from AMD for the Ryzen Threadripper family of microprocessors, introduced on August 10, 2017. Physically very close to the AMD Socket SP3 server socket, however, it is not compatible with it.
