Socket 478: processor, motherboard. Features Socket 478

In August 2001, the “Intel” was forced to hastily introduce a new computing platform in the face of the Socket 478. Moreover, this socket has replaced the two previous solutions - “the Socket 370” and “the Socket 423”. The first of them at the time is outdated and no longer met the requirements that were put forward to the performance of the computer. And the second is not widespread due to the fact that they could not compete on equal terms with competing "Socket A" from "AMD" in price due to the expensive memory - RIMM. That's the wave of these events and emerged the hero of this review.

Appearance and life cycle of the platform PGA478

As mentioned earlier, the start of sales Socket 478 peaked in 2001. Moreover, this product came in very much difficult situation to “Intel”. "AMD" at this point, continued to develop its most successful in the history of the platform - "Socket A". Clock frequency she grew not so much, but the performance, on the contrary, increased at an impressive pace due to a variety of engineering solutions (e.g., increased cache). Products “Intel” can not on equal compete with it. Old “the Socket 370” reached the maximum of their capabilities, and something more to get from him was impossible. A new PGA423, though, and won on performance, but cost significantly more expensive due to the used of a special type of RAM.

So was released and the second CPU socket for Pentium 4, which combines a sufficient level of performance and support for low-cost DDR memory. Itself this computing platform has successfully existed until 2006, when it was replaced with LGA775. Among its other features should also be support for NT, for the first time implemented in the framework of this platform and instead allowing one physical computing module to receive two thread processing of program code and data.

Chipset

An Impressive set of chipsets were bound to Socket 478. Motherboard To use as the groundwork itself “Intel” and third-party manufacturers. In the list of last logged on SIS chipsets 6XX series with ATI products Xpress and the NVidia chipsets with the NForce lineup. But still the best in this case was considered to be the solution from “Intel”. For entry-level PCs was released i845 with low price and acceptable equipment. In the middle segment of the market targeting specific chipsets i865. He had improved functionality and higher performance. On the niche of the most productive products were oriented i875 with even more improved specs, but the cost had been significantly higher.

RAM

Two possible types of RAM can be used in combination with the updated Pentium 4. 478 Socket supported SDRAM and DDR. But the first type of RAM at that time were obsolete and as a result, the combination of it with the new socket has reduced the performance of the computer as a whole. Therefore, the most widespread system Board, which were based on bars of the standard DDR. The controller in this case was integrated into the chipset. More specifically, in North bridge. He could work in dual channel mode, and it is possible to further increase the performance when using 2 or 4 memory modules.

Model number of CPU

Not so long list of models CPU supported Socket 478. The processors in this case there was only a single core and they belong to two lines. The first of these took the initial market segment is the Celeron chips. And the second part of the CPA focused on the Assembly of the PC mid or even premium segment and it belonged to the Pentium 4. The key difference between them consisted in increased operating frequencies and greater volume of the built-in cache. More detailed information on products for Intel Socket 478 (Pentium 4 and Celeron processors for the desktop version) is given in the table below. They can still choose to purchase in used condition at various shopping sites online.

So, consider the characteristics of the CPU to the CPU socket of PGA478.

Current situation with the platform and its prospects

Of Course, Socket 478 Totally and completely does not meet modern requirements for speed and efficiency put forward to the PC now. But this computing platform continues to be used. Its scope is office computers with low productivity. In this niche such system units even now I feel fine. Welland what more to expect from PC 2001-2006 model years is not necessary. Many of the ideas within this socket was first implemented (e.g., technology, NT), even now continue to be actively used.

Results

As a result, it can be noted that Socket 478 is currently already outdated, and the owners of such system units, it is better to think about upgrading computers. Such a PC already completely exhausted their resource and will be properly planned in advance of them and replace with more fresh solutions with improved performance and higher efficiency.
