Since the very first CPU, both Intel and AMD have been creating several different sockets to be used by their processors. In this tutorial, we will list all socket types released to date with a list of compatible CPUs.
In the beginning, a CPU socket was compatible with just one kind of processor. This scenario changed with the launching of the 486 processor and the massive use of ZIF (Zero Insertion Force) sockets, also known as LIF (Low Insertion Force). The ZIF socket has a lever that installs and removes the CPU from the socket without the need of the user or the technician to press the CPU down in order for it to be installed on the socket. The use of this socket greatly lowered the chances of breaking or bending the CPU pins during its installation or removal. The use of the same pinout by more than one processor allowed the user or the technician to install different processor models on the same motherboard by merely removing the old CPU and installing the new one. Of course, the motherboard needed to be compatible with the new CPU being installed and also properly configured.
Since then, both Intel and AMD have been developing a series of sockets and slots to be used by their CPUs.
The socket created to be used together with the very first 486 processor wasn’t ZIF and didn’t allow you to replace the CPU with a different processor model. Even though this socket didn’t have an official name, let’s call it “socket 0.” After socket 0, Intel released socket 1, which had the same pinout as socket 0 with the addition of a key pin. It also adopted the ZIF standard, allowing the installation of several different types of processors on the same socket (i.e., on the same motherboard). Other socket standards were released for the 486 family after socket 1 (socket 2, socket 3, and socket 6) in order to increase the number of CPU models that could be installed on the CPU socket.
Thus, socket 2 accepts the same CPUs accepted by socket 1 in addition to some more models, and so forth. Even though the socket 6 was designed, it was never used. Thus, we usually call the pinout used by 486-class processors as “socket 3.” Originally, Intel defined “overdrive” as the possibility of a socket to accept more than one CPU model. Intel also adopted this name on newer CPUs that used a pinout from an older CPU in order to allow the new CPU to be installed on an older motherboard.
The first Pentium processors (60 MHz and 66 MHz) used a pinout standard called socket 4, which was fed with 5 V. Pentium processors from 75 MHz on were fed with 3.3 V, requiring a new socket, called socket 5, which was incompatible with socket 4. (For example, a Pentium-60 couldn’t be installed on socket 5 and a Pentium-100 couldn’t be installed on socket 4.). Socket 7 uses the same pinout as socket 5 with the addition of one key pin, accepting the same processors accepted by socket 5 plus new CPUs, especially CPUs designed by competing companies.
(The real difference between socket 5 and socket 7 is that while socket 5 always fed the CPU with 3.3 V, socket 7 allowed the CPU to be fed with a different voltage level, such as 3.5 V or 2.8 V, for example.) Super 7 socket is a socket 7 capable of running up to 100 MHz, used by AMD CPUs. We usually call the Pentium Classic and compatible CPUs pinout as “socket 7.”
As you may notice, sockets and pinouts at this stage were very confusing, as a given processor could be installed on different socket types. A 486DX-33 could be installed on sockets 0, 1, 2, 3 and, if it were released, 6.
For the next CPUs manufacturers followed a simpler scheme, where each CPU could be installed on just one socket type.
On the next pages, we list all socket types created by Intel and AMD since the 486 CPU, with a list of CPUs compatible with them.

Hello everyone My first computer was exactly on the 478 socket platform, I remember that the motherboard was Asus (yellow, probably something like the P4800 model) .. And there was only 256 MB of RAM … Then it was modern. And this is 2003-2004. 478 socket was in full swing, new processors were coming out, but nevertheless there were already rumors about the future 775th socket. Oh, that they just didn’t attribute to him and how they just didn’t expect him. But that’s a completely different story…
The
478 socket supports, if I’m not mistaken, two families of processors, these are Celeron and Pentium 4. All of them were made with a clumsy process technology — 130-90 nm.
I’m not going to lie that I really don’t know. I just know that the less the better. For comparison, now I have a Pentium G3220 (1150 socket), so here the frequency is even lower than that of the top-end processor on socket 478. But it is probably five times more productive. So. The manufacturing process of the Pentium G3220 is only 22 nm. Here you can see the difference.
The most powerful processor for 478 sockets is the Pentium 4 EE, i.e. Extreme Edition. These were processors based on the Gallatin core (released in 2003) and later released on the Prescott2M core (record 2 MB cache). On socket 478, everyone had a 800 bus, and if I’m not mistaken, a 1066 MHz bus has already appeared in socket 775.
Prescott was generally positioned as a new core with numerous improvements. But in fact, the improvements were dubious, but the shoals are decent. It was all about temperature. Processors on the Prescott core, and especially on Prescott2M, had a very high temperature already at an average load of
Prescott2M differed from just Prescott mainly only in the cache size of 2 MB.
So, let’s draw some conclusions. The most powerful processor for 478 socket today can only be obtained second-hand, it costs about $10-$30. This is an EE model or close to it. Such a processor should have a frequency of 3.4 or slightly lower, but the most important thing that was a breakthrough for that time was Hyper-threading technology. That is, in Windows it was like a dual-core. But in reality it was two streams. It is even better to take the processor not on the 533 bus, but on the 800 one. And it’s better not on the Prescott core, but on Northwood (in fact, this is the Gallatin server core). And if you still disperse it … eh …
The maximum frequency, as I already wrote, is 3.0 — 3.4 GHz, of course, ideal if you find 3.4
In principle, top-end processors on socket 478 heat up just like modern top-end ones, maybe a little more. Because top is top. I advise you to take the motherboard where there are solid capacitors near the processor socket. Such, for example, were made by Intel at that time, maybe someone else, but I don’t remember.
Here is an Intel board with solid capacitors:

Or like this:

Boards where there are such capacitors everywhere, then there were simply no such ones. Just make sure that there are as many of them as possible near the processor compared to electrolytic capacitors (these are ordinary ones that like to swell and explode).
But this is my personal advice. Intel boards are not bad, but Asus seemed to be better, and to be more precise, the Asus P4C800-E Deluxe model. But they do not have solid-state capacitors, and the chance that capacitors will swell later on the motherboard is very high. It is the most important ones that are related to the power of the processor that will swell …
In general, I wrote a little bit of everything.
The best processor for 478 socket is: frequency 3.4 GHz (or at least 3 GHz), cache size 2 MB, Northwood core (prescott2M at least) and Hyper-threading technology (although all top models have it).
Screenshot from the CPU-Z program, an example of a normal processor:
Just in case, I give you a link to the official Intel website, where the model of the most powerful processor on the 478 socket is presented.
As for the temperature in general, I do not quite understand. I had a top Pentium 4 670 processor, yes, it heats up hard. But I had it on socket 775. But that’s not the point. I installed a medium-sized radiator, installed a large cooler but at low speeds (so as not to make noise), and removed the side cover of the computer. As a result, the temperature never exceeded 50 degrees. So there is no horror that many describe, well, at least I didn’t see it. True, maybe it was a matter of stepping … You just need to understand that the processor is top-end and hot and you shouldn’t cool it like some Celeron
Are there dual core processors on socket 478? No guys, it’s too much for you.
There have never been dual-core processors on socket 478, the maximum that was, as I already wrote, was two threads (HT). This technology was already borrowed from server processors. The first dual cores are not Pentium 4 at all, they are already Pentium D (D is of the Dual type). And then, the first copies were far from being very successful compared to the top-end Pentium 4 HT.
I’ll also give you advice on the motherboard. Well, I already wrote that it’s good when solid capacitors are used on it. But few people know that in addition to solid-state boards, there are also boards with DDR2 support. At the same time, you can even find new ones on the Internet. I really know only one model, this is the Biostar G31-M4 (by the way, there was even a backplate for the processor in the kit):
ADVERTISING
This board is just the perfect solution to reanimate an old computer on socket 478.
You can also buy new DDR2 memory and the computer will come out more or less normal, well, I mean if there is also a top-end processor … This board also has a unique connector for this platform, this is PCI-Express. That is, in theory, you can even install a decent video card … And if you also take into account that the board has SATA2 ports, then the SSD will give a new life to the computer … (due to access speed) This way you can assemble a really good office system unit or for playing old games . But again, if you look sensibly, then there is little point in this … This is all of course off topic, I’m just a small fan of old computers, I don’t know why
That’s all, I hope that this info helped you somehow

Characteristics of Socket 478
In August 2001, Intel was forced to hastily introduce a new computer platform in the face of Socket 478. Moreover, this processor socket replaced two previous solutions at once — Socket 370 and Socket 423. The first of them was outdated at that time and no longer met the requirements that were put forward for computer performance. And the second one was not widely used due to the fact that it could not compete on equal terms with the competing Socket A from AMD in terms of price due to expensive RAM — RIMM. It was on the wave of these events that the hero of this review appeared.
Time of appearance and life cycle of the PGA478 platform
As noted earlier, Socket 478 sales started in 2001. Moreover, this product appeared in a very difficult situation for Intel. AMD at this point continued to develop its most successful platform in history — Socket A. Its clock speeds did not grow that much, but the performance, on the contrary, increased at an impressive pace due to various engineering solutions (for example, an increase in cache memory).
Intel’s products could not compete on an equal footing with it. The old «Socket 370» reached the maximum of its capabilities, and it was no longer possible to get something more from it. And the new PGA423, although it won in terms of performance, was several times more expensive due to the special type of RAM used.
That’s why the second processor socket for the Pentium 4 was released, which combines a sufficient level of performance and support for inexpensive DDR RAM. This computing platform itself successfully existed until 2006, when it was replaced by the LGA775. Among its other features, it is also necessary to highlight the support for NT technology, which was first implemented within the framework of this platform and allows, instead of one physical computing module, to get two streams of processing program code and data at once.
Chipsets
An impressive set of chipsets were tied to Socket 478. Motherboards could use both Intel’s own developments and third-party manufacturers.
The latter included SIS with the 6XX-series chipset, ATI with Xpress products, and NVidia with NForce chipsets. But still, in this case, solutions from Intel were rightfully considered the best. For entry-level PCs, the i845 was released with a low price and acceptable bundle. The i865 was aimed at the middle segment of the market. It had improved functionality and higher performance. The i875 with even more improved specifications was oriented towards the niche of the most productive products, but its cost was several times higher.
RAM
Two possible types of RAM could be used in combination with the updated Pentium 4. 478 Socket supported SDRAM and DDR. But the first type of RAM at that time was obsolete and, as a result, its combination with a new socket reduced the speed of the computer as a whole. Therefore, the most widely used motherboards, which were based on the strips of the DDR standard. The controller itself in this case was integrated into the system logic set.
To be more precise, to the north bridge. It could work in dual-channel mode, and this made it possible to obtain an additional increase in performance when using 2 or 4 RAM modules.
CPU range
Not such a large list of CPU models supported Socket 478. In this case, the processors were only single-core and they belonged to two lines. The first of them occupied the initial segment of the market — these are Celeron chips. And the second part of the CPU was focused on assembling PCs of the middle or even premium segment and it belonged to the Pentium 4 line. The key difference between them was increased operating frequencies and a larger built-in cache. More detailed information on products for Intel Socket 478 (Pentium 4 and Celeron for desktop version) is given in the table below. They can still be purchased in used condition at various online marketplaces if desired.

Current situation with the platform and its prospects
Undoubtedly, Socket 478 does not fully meet the modern requirements for speed and energy efficiency, put forward to the PC now. But this computing platform continues to be used. Its scope is office computers with low performance. In this niche, such system units even now feel great. Well, you can’t expect anything more from a PC manufactured in 2001-2006. Many developments that were first implemented within the framework of this socket (for example, HT technology) continue to be actively used even now.
Results
As a result, it can be noted that Socket 478 is already very outdated at the moment, and it is better for owners of such system units to think about updating the computer.
