Intel Core i5-750 processor overview: specifications, description and reviews

2009 was marked by the release of the updated processor architecture Lynnfield, the most accessible representative of which was at that time chip "Kor i5-750". The characteristics of this semiconductor product is not so much different from the modern quad-core CPU of this manufacturer. Therefore, this processor still continues to be relevant and allows you to solve most of all kinds of tasks at the moment.

The niche of the processor market, to which the hero of this review was oriented

With the release of the LGA1156 platform, Intel has divided the microprocessor market into the following segments:

• The entry-level PCs were based on Celeron processors (these chips provided the minimum level of performance sufficient for office computers) and the Pentium (in this case, one could even count on launching some new toys with minimal settings, but the gaming system could only be called gaming with a stretch ). The difference between these two products was to increase the size of the cache and increase the clock speed of the processor, and this allowed to get in practice an additional percentage of performance.

• The segment of the average level was occupied by chips of the i3 and i5 families. It was to this group of CPUs that the processor solution considered in the framework of this material belonged. The younger i3 models included only 2 physical blocks of code processing. But due to the introduction of proprietary technology HT, this semiconductor crystal at the software level could already process information in 4 streams. But i5 were full-fledged processors with 4 physical cores. They also increased the cache memory capacity and introduced support for TurboBoost technology. The latter allowed to adjust the frequency of the CPU depending on the degree of optimization of the program code for multithreading, the thermal state of the semiconductor crystal and the level of complexity of the problem being solved.

• The most productive system units, both then and now, are based on chips of the i7 family. They have 4 physical blocks of code processing, but the support of HT technology allows 8 programs to be received at the software level. Also the frequency formula in this case is increased, as well as the cache memory.

Though formally the hero of this review is related to middle-class processor products, nevertheless, among practically all existing software at that time, it could easily compose a worthy competition to the flagship microprocessor. Most software is even now focused on the use of 4 physical cores, and it is for this reason that there is not much difference in performance between the older CPUs of this manufacturer at the current time.

Contents of delivery

This product was sold in two versions. More modest of them was called TRAY. In this case, in addition to the CPU itself, an instruction manual, a warranty card and a sticker with the name of the chip model for the front panel were purchased. This bundle is aimed primarily at large assemblers of system blocks, but it was also sometimes purchased by computer enthusiasts. The second option for bundling this processor product was called BOX. In the common people, the name "box version" was assigned to him. In this case, the list of supplies was supplemented by a cooler and thermal paste.

Processor Connector

The installation of the LGA1156 socket was oriented "Kor i5-750". The characteristics of this processor socket indicated that it was oriented to assembling single-chip system units. This socket allowed in 2009 to organize completely different by purpose and cost computing systems. This computer platform remained valid until 2011, when it was replaced by LGA1155. But even now the products of this series continue to be relevant for at least one reason that the level of their performance still allows you to solve most problems.

Semiconductor chip manufacturing technology

By typical technology, at the beginning of 2009, Kor i5-750 was produced. The characteristics of all this generation of chips indicate that they were all produced by a 45 nm process technology. At that time it was perfectly worked out and there were no significant problems with the release of suitable silicon wafers in this case. In the future, it was replaced by a technology with a tolerance of 32 nm.

Cache

Like all modern most advanced processor products, the three-level cache has Intel i5-750. The characteristics of this semiconductor product in this case are:

• The first level included 4 segments of 64 KB bound to a specific computing module.

• Similarly organized 4 blocks of 256 KB on the second level.

• The cache memory on the third level was common to all CPU resources and had a total size of 8 MB.

RAM

The memory subsystem in the LGA1156-based solutions, including the Core i5-750, was substantially reworked. The characteristics of this product indicated that the north bridge, together with the memory controller, was transferred from the motherboard to the semiconductor chip of the central processor. This allowed to significantly increase the speed of RAM. But, on the other hand, the integration of the RAM controller led to the fact that the chip could only function with a certain list of memory slots. In this case, this set was limited to DDR3-1066. Also, in combination with this CPU, faster memory cards could be used, but the frequency of their work was limited to only one value - 1066 MHz. Something greater in this case was impossible to obtain.

Temperature Range. Thermal package

On a thermal package of 95 W the processor i5-750 was calculated. The characteristics of this CPU model indicate a maximum allowable temperature of 72 degrees. In the usual mode, the temperature mode of this chip was limited to values of 40-50 degrees. In the case of overclocking, this range increased and was already within the limits of 50-60 degrees. In practice, to load this CPU so in the nominal operating range so that it reaches the maximum possible value it was impossible. Only two cases could be left behind the established borders. One of them is the breakdown of the cooling system, and the second is the chip overclocking in combination with the complete cooler and the launch of several resource-intensive applications on the PC.

Frequencies

At 2.7 GHz, the initial frequency was set for the Intel Core i5-750. Characteristics This CPU pointed to the support of TurboBoost technology. That is, this processor could adjust the frequency value and the number of active calculation units. When using all four units, the maximum frequency was limited to 2.8 GHz. If the processor was operating in a dual-stream mode, then the frequency value was 2.93 GHz. Well, in the case when only one calculation unit was running, this value could be raised to 3.2 GHz. There was also the possibility of overclocking this CPU. As experience shows, with proper equipment of the system unit, it was possible to overclock this processor to 4 GHz and get almost a 30% increase in performance due to this.

CPU Architecture

As noted earlier, 4 physical processing modules included Intel Core i5-750. The characteristics of this product indicated that it did not support the HyperTrading technology. Therefore, at the software level, it was represented by the same 4 threads. And this value even today continues to be relevant due to the fact that most of the software is optimized for a maximum of 2 or 4 streams. In this case, the difference with the more expensive CPUs of the i7 family was practically not felt.

The opinion of the owners. Price

At $ 213 this version of Core i5 was evaluated. CPU 750 (its characteristics were really excellent as for 2009) allowed to solve any problems. And even now, this CPU can easily cope with almost all the loads. Only with the most recent toys can problems arise. But in this case, you can lower the quality of the output image, which will fully immerse yourself in excellent gameplay.

Results

A worthy processor product for 2009 was "Kor i5-750". Its characteristics continue to this day to be relevant and allow still to solve most problems. Also, the advantages of this CPU model require affordable cost, the availability of four physical code processing units and excellent energy efficiency, both for the 2009 chip. But still owners of such system blocks will very soon have to think about the planned update of their computing system.
