Intel Core 2 DUO E7400 Processor: Features, Features and Feedback

This article will consider an excellent 8-year old CPU - Intel Core 2 DUO E7400. The characteristics of this chip to date can not be called relevant, but it still looks great as a basis for the system units of office or budget. It is in this context that its specifications will be considered.

CPU niche

At the time the sales began, this processor belonged to middle-class solutions. Most of the existing software at that time on it could quite successfully function. Of course, some toys on this hardware were not at the maximum settings, but still they were mandatory started. But now the situation has changed. In some of the most recent and most demanding toys there is a test for the presence of 4 cores, and there are only 2 cores in this chip. Therefore, such software will not work on it. As a result, such chips relate to semiconductor solutions of the initial class.

Delivery options

In two possible versions of the bundle was supplied the Intel Core 2 DUO E7400 processor. указывает на ВОХ и TRAIL. The description on the official website of the manufacturer indicates the VOH and TRAIL. The second one was more modest and included the following:

• The chip itself.
• Branded sticker with the logo of the CPU model.
• Warranty card from the manufacturer.
• A quick guide to using a semiconductor product.

включал следующее: The first option was more extensive and, in addition to all the previously listed, included the following:

• Branded cooler.
• Thermal grease.

Processor connector. General characteristics of CPU

The Intel Core 2 DUO E7400 was supposed to be installed in the main and most common processor socket at that time.

LGA775. Characteristics indicate support for LGA775. To date, all the processors of this socket are obsolete and out of production. But there is still its stock of stocks, and therefore it is still possible to buy such semiconductor products. This processor has only 2 compute modules. Also, it does not support HT technology and the second increase in the number of logical streams at the software level can not be obtained in this case.

Production technology

According to the most advanced technical process in 2008, Intel Core 2 DUO E7400 was produced. The characteristics of this silicon crystal indicate tolerance levels of 45 nm. Now the most advanced CPUs are already manufactured at 14 nm. между героем данного обзора и бюджетными центральными процессорами последнего поколения. Taking into account the difference of 3 times and taking into account the time interval of 8 years, it turns out not so much a difference between the hero of this review and the budget central processors of the latest generation.

Cache

Only 2 levels of cache are in "Cor 2 DUO E7400". In 2008, among the chips for conventional personal computers, it was still impossible to meet the 3-level memory cache. Therefore, in this respect, this chip did not stand out as something special. Now this is one of the reasons why this CPU can not compete on the speed with the most affordable processors of the last several generations. The first level had a total size of 64 KB. At the same time they were divided into 2 equal parts, the size of each of which was equal to 32 KB. The second cache level was common for all CPU resources and was 3 MB in size.

RAM

был рассчитан процессор Intel Core 2 DUO E7400. For use in conjunction with DDR2 memory , the Intel Core 2 DUO E7400 processor was designed. The characteristics of this CPU indicate the recommended frequencies of 800 MHz or 1.066 MHz. The memory controller, unlike the current chips, was not part of the semiconductor chip of the CPU. Therefore, its specific performance depended on the set of system logic on the motherboard.

Frequency. Overclocking

The clock frequency for this semiconductor solution was set at 2.8 GHz. The multiplier for this CPU is set to 10.5. This value is fixed and it is impossible to disperse this chip by a simple change of this parameter. Therefore, the only way to increase the speed of such a PC is to increase the frequency of the system bus on the motherboard. Its value is set at 266.7 MHz. In practice, with a high-quality cooling system, the system bus frequency could be raised to 390 MHz and get a 4.1 GHz chip for the chip. As a percentage, this is 46%. As a result, it can be noted that this CPU had excellent overclocking potential.

Reviews. Price

был оценен производителем данного чипа. At $ 110 at the beginning of sales, the TRAIL option was evaluated by the manufacturer of this chip. In 125 dollars, the more advanced equipment of the Intel Core 2 DUO E7400 was evaluated. Characteristics (reviews of owners and experts confirm this), this CPU is very modest, and it is inferior in speed to even the most budgetary processors of the latest generation. The key difference here lies in the frequency and cache memory, which currently has a three-level organization. You should also take into account the fact that this processor was released long ago, and therefore it is not worth considering it as a basis for the gaming system. It is obsolete and suitable only for the solution of the most simple tasks: playback of video or audio recordings, web surfing and office programs. Also to this list you can add the current least demanding or even obsolete old toys. не получится. Something more of this semiconductor CPU can not be squeezed .

Results

Intel Core 2 DUO E7400. For 2008, an excellent processor solution was Intel Core 2 DUO E7400. His characteristics were really good at that time. этот ЦПУ устарел как морально, так и физически. But now this CPU is outdated both morally and physically. Over the past time, he moved from the niche of middle-class products to the budget segment. As a result, it is possible to solve only the simplest tasks on such personal computers. Well, for something more to use such a computing system does not work.
