Page 1: Ivy Bridge Test and Review: Intel Core i7-3770K and All Core i5 Models
Meet the next tick: April 23, 2012 Intel announces new Ivy Bridge processors. A total of 14 new desktop and notebook models are introduced. Add to this eight varieties of chipsets that have already been partially presented, as well as five options wireless communication. In this article, we will take a closer look at desktop processors, and our second review is devoted to mobile CPUs.
The third generation of the Intel Core microarchitecture is a "tick" from the Intel "tick-tock" model, that is, it implies a reduction in the technical process. In theory, Intel should have taken the micro-architecture of the previous generation "Sandy Bridge" and reduced the process technology. As a result, the CPUs would be made on a 22nm processor, incorporating the new Tri-Gate transistors from Intel.
But Intel decided to optimize the CPU a bit and make a number of improvements. Thus, Ivy Bridge processors are not just Sandy Bridge models with a smaller process technology. As emphasized in Intel's marketing materials, the new CPUs are "tick+". However, as we will see below, the improvements have mainly affected only the graphics core.
For tests, we received the following processors, which clearly show that Intel decided to change the naming scheme again.
- Intel Core i7-3770K
- Intel Core i5-3570K
- Intel Core i5-3550
- Intel Core i5-3450
The Intel Core i7-3770K is the new top model in the family, designed to replace the Core i7-2700K. The clock speeds are shown in the table below - they have shifted slightly compared to the previous generation. The Core i5-3570K has been announced to replace the very popular Core i5-2500K processor. Hyper-threading support not to be expected, as with all Core i5 models, but the CPU clock speeds are quite high. The third and fourth Core i5-3550 and Core i5-3450 models we received are the current processors entry level in the Ivy Bridge family (Core i3 models to be announced later). All Ivy Bridge processors have at their disposal a DDR3-1600 memory controller, which allows you to count on a slightly faster dual-channel memory interface.
Introducing the test: new flagship Intel for the desktop segment, the Core i7-3770K processor, as well as the younger models of the Ivy Bridge family.
The following table summarizes the performance of the desktop CPUs in our testing:

In addition to those listed Intel models also sells the Core i7-3770 processor. This model does not have an unlocked multiplier, and the frequencies are somewhat different: the Core i7-3770 has the same frequency response in Turbo modes as the Core i7-3700K processor, but the base frequency is 3.4 GHz. So the processor will be slower than the "K" model, but only if Intel Turbo Technology is turned off. Among the advantages of "non-K" processors, one can note support for vPro, VT-d, TXT and SIPP technologies - however, overclockers are unlikely to be interested in these functions.

...and i5-3550 and i5-3450
Intel processors The Core i5-3550 and i5-3450 use lower clock speeds (Turbo peaks at 3.7 and 3.5 GHz). In addition, these models do not use the "older" graphics core Intel HD Graphics 4000, but the "younger" version of the Intel HD Graphics 2500, which has reduced computing units. The "younger" i5-3450 processor also lacks support for vPro, VT-d, TXT, and SIPP.
In addition to the standard models with a TDP of 77W, Intel also introduced four processors with a lower TDP: the Core i7-3770S and i7-3770-T are very close to the Core i7-3770 processors, although they differ in clock speeds, but at the same time the TDP is reduced to 65 or 45W, the voltage and frequencies are reduced. The Core i5-3550S and i5-3450S processors have a TDP of 65W and match the Core i5-3550 and i5-3450 processors, but again, the voltage and frequencies are reduced.
If you've been following our news, you've probably noticed the message
The line of Core i5 processors from the global manufacturer Intel is represented on the market by a wide variety of models with different characteristics, so many users who are fond of overclocking the CPU face various problems when choosing this device.
First of all, this is due to the fact that not all novice IT specialists know what parameters to pay attention to when choosing a CPU. This article will tell you about all the nuances associated with choosing an Intel Core i5 processor and how to properly overclock it.
General information about Core i5 processor models
Intel processors Core third generations are represented on the market not by one model, but by a huge line designed for the average consumer who needs a reliable and productive processor at an affordable price. 3rd generation Intel Core processors combine second generation affordability with high specifications fourth generations. Thus, Intel Core i5 is the optimal solution for most personal computers.
CPU overclocking
In most modern models of Intel processors, including the Core i5, the innovative patented Turbo Boost technology is implemented, which allows you to overclock the processor in order to increase CPU performance. automatic mode. These processors have a microchip responsible for graphics processing.
All models of Intel Core i5 processors are available with clock speeds ranging from 1.2 to 3.6 GHz. The data transfer rate over the serial bus is 2.5 GP/s. Depending on the year of issue, Core processors i5 can be built on 32nm or 45nm dies, depending on the architecture implemented in the CPU. In addition, models are divided into dual- and quad-core with 256 KB L2 cache and 4 to 6 MB L3 cache.
According to many experts, you can significantly increase the performance of most Intel Core i5 processors by overclocking. Therefore, it is necessary to study in more detail the dependence of technical characteristics and overclocking.
Intel Core i5 Processor Architecture
Before starting to consider the characteristics of the CPU, it is necessary to understand how the processors are arranged. All Intel Core CPU models are based on the modern Sandy Bridge architecture, which provides processors with high performance and good technical characteristics. However, when it comes to overclocking, this architecture does not show the best results.
Sandy Bridge architecture features
The thing is that the manufacturer has blocked most of the key multipliers that affect the quality of overclocking in processors built on the Sandy Bridge architecture. Therefore, the maximum frequency increase threshold will not exceed 900 MHz, which is quite small from the point of view of professional specialists in the field of computer hardware.
However Intel releases processors of the Core i5 family, in which, if necessary, you can independently adjust the value of multipliers. One of these CPUs is the Core i5-2500K model, which has gained great popularity among the masses. According to many IT people, the clock speed of these processors can be overclocked up to 5 GHz. Many users prefer this particular model also because it has a low cost. Thus, for only $200, you can get a processor whose performance will not be inferior to top models.
Ideal processor for overclocking
According to many experts, if you decide to purchase an Intel Core i5 processor for the purpose of further overclocking, then it is best to opt for the 2500K modification. This model has a low cost and allows you to significantly increase the performance of the CPU. According to some technical characteristics, it is not inferior even to Core models i7, the cost of which is several times higher. Thus, the Intel Core i5-2500K is the perfect combination of performance, affordability and overclocking characteristics.
Of course, more modern and advanced technologies are implemented in Core i7, for example, the size of the third-level cache in them is 8 MB, versus 6 MB in Core i5, however, in practice, this difference will be practically not noticeable when performing most tasks.
General information about the Intel Core 2500K processor
Continuing consideration Intel specifications Core i5 2500K, one cannot fail to mention the adaptation of the processor to modern computer games. In addition, the CPU has four cores, which has already become a kind of standard in the manufacture of gaming processors, because a large multi-core processor is far from always a justified step, since multitasking has no effect on gaming processes and is, by and large, useless.
The iron factor
Starting to overclock your processor, you need to choose high-quality components for the CPU. The performance of the accompanying hardware should not be inferior to those of the processor, otherwise the experiment may not end very well or even lead to CPU failure. At Intel overclocking Core i5-2500K computer specifications should not be inferior to the following:
- a powerful processor cooling fan with a speed of at least 1800 per minute;
— graphics system Radeon HD 5870 and above;
- at least 4 GB random access memory class DDR3 and throughput 1600.
Besides system unit it is desirable to equip with additional coolers.
Factor software
According to some advanced users, overclocking the processor is something like an experiment, so the quality of the software also plays a big role. Concerning operating system, then Windows 7 and above is quite suitable for these purposes. In addition, it is very important that all devices have compatible drivers latest version.
Results require measurements
Performing such a complex procedure as overclocking a processor involves the use of special software, among which one of the most important is a utility for measuring the result. For this purpose, 3D Mark can do an excellent job. According to many experts, it displays up-to-date information about the performance of each core during overclocking, and also provides detailed information at the end of the process. comparative characteristic CPU performance before and after overclocking.
No less popular among many professional IT specialists is the SiSoft Sandra utility, which allows you to get detailed information not only about the performance of the chip, but also about each individual computer device. The program has a wide range of various tools, however, the most relevant of them are arithmetic and cryptographic tests.
Some experts argue that the processors of the Core i5 family are adapted to work with programs that work on the principle of a chess algorithm. One of these utilities is Fritz Chess Benchmark, which measures the performance of processor cores based on the processing speed of incoming commands and the time it takes to complete the tasks assigned to it.
Programs at your fingertips
Fritz Chess Benchmark is a professional software designed specifically for CPU overclocking and allows you to evaluate how successful CPU overclocking has been. However, in order to obtain more reliable information, it is recommended to use the set together with this utility. standard programs. For example, a conventional archiver that allows you to evaluate the speed of packing or unpacking data, as well as the stability of the processor during the execution of tasks.
In addition, it can be very effective graphics editor Photoshop, which creates a large load on the CPU during image processing and the use of various filters. If during image processing the processor normally copes with its tasks, then in this case the overclocking was successful and you don’t have to worry about the stability of the CPU.
What other software can I use when testing the performance of overclocked Intel Core i5 processors? The Linpack utility, which allows you to test hardware for the speed of solving algebraic equations, may be useful. In addition, any program that allows you to monitor changes in CPU temperature is useful. As such, Real Temp is quite suitable. Another and very useful utility is CPU-z, which provides a detailed report on the performance of all devices in the computer.
Game Factor
As mentioned earlier in this article, microprocessor intel Core i5-2500K belongs to the gaming type. This is evidenced by high technical characteristics, for example, the clock frequency, which in the basic modifications of the CPU is 3GHz. Therefore, when overclocking your processor, it is worth testing its performance in modern mode. computer games or using specialized software that simulates a computer environment. This can be done using the powerful FRAPS utility.
However, before proceeding directly to the test, you must first run the processor for default settings. By measuring the factory parameters, you can gradually increase the frequency of the multipliers. Read more about how to do this in the article.
BIOS Features
One of the easiest and most reliable ways to overclock a processor is to change the appropriate multiplier settings in BIOS. To do this, you need to restart the computer and enter the BIOS settings menu using the DEL key, which is set by default by the manufacturer. Some BIOS versions can use other keys or their combinations to enter, however, as a rule, a hint is displayed on the screen at the very beginning of the launch, which you can use.
After the BIOS starts, you need to go to the Frequency Control tab, which contains the control of the base multipliers, of which only two are important - the operating frequency of the central bus, measured in MHz, as well as its coefficient. It is worth noting that it is not recommended to adjust the bus frequency, since the architecture of the microchips implemented in the Intel Core i5 processors does not provide for manual adjustment of this parameter. In addition, increasing the frequency of the system bus will not give a noticeable increase in performance.
How to achieve a progressive increase in productivity?
You can achieve an increase in CPU performance by adjusting the bus frequency factor. In the Intel Core i5-2500K processors, the developers have provided for an increase in this parameter to 57. However, in order not to burn the processor during overclocking, it is not recommended to set the coefficient immediately to the maximum, but to increase it progressively. Experts claim that CPU overclocking you can start with the initial value of the coefficient value of 40. If the processor becomes unstable, it should be lowered.
According to some experts, to achieve more high performance when overclocking the processor, you can also use the CPU voltage control. However, the opinions of various experts on this issue differ. If you still decide to take advantage of this opportunity, then you should start with a voltage of 1.15 V. Many experts argue that this value is optimal for achieving the best results when overclocking the Intel Core i5-2500K processor.
Practical results
What maximum performance processor can be obtained by overclocking? How much will the installation of Intel Core i5 affect the gaming experience? According to IT-specialists, the results can exceed any expectations, so installation and overclocking justify themselves. During numerous experiments, it was found that the technical characteristics of the processor justify themselves in terms of reliability and protection against overheating.
In other words, having overclocked the processor to the maximum available frequency, its maximum temperature will not exceed the maximum allowable limit. Therefore, if necessary, users get the opportunity to control the values of the multipliers at their discretion. However, in this case, the operation of the system may be unstable. Its testing should take place simultaneously using several specialized utilities.
Processor overclocking is an opportunity to increase the performance of your computer without any financial costs. Each user gets the opportunity to get a powerful game processor, the cost of which does not exceed the budget options. With proper overclocking and judicious use of multiplier values, Intel performance Core i5 will be comparable to higher generation processors.
