In 2010 Intel company introduced new brands of processors - Core i3, i5, i7. This event confused many users. And all because the company’s goal was completely different - it wanted to offer more quick way identifying patterns of low, medium and high levels. Intel also wanted to convince users that Intel Core The i7 is much better than the same i5, and this one in turn is better than the i3. But this does not give an exact answer to the question, which processor is better or what is the difference between Intel Core i3, i5 and i7 processors?

A little later, the company released new generations of processors based on such architectures as Ivy Bridge, Sandy, Haswell, Broadwell And . Such innovations have further confused many consumers. Although such new technologies have appeared, the names have not changed - Core i3, i5, i7. The differences between these technologies are only as follows: Processors with i3 are intended for small (basic) class computers, i5 processors for computer systems middle class, and i7 processors for high-class computers, for powerful PCs, in simple words.

But there are still other differences that we will talk about.

Key points

Some users believe that the names i3, i5 and i7 are related to the number of cores in the processor, but in fact this is not the case. These brands were chosen randomly by Intel. Therefore, the chips of all these processors can have either two or four cores. There are also more powerful models for desktop computers, which have more cores and are superior to other processors in many respects.

So, what are the differences between these three models?

Hyper-Threading

When processors were just being born, they all had one core that executed just one set of instructions, namely thread. The company was able to increase the number of computing operations by increasing the number of cores. Thus, the processor could perform more work per unit of time.

The company's next goal is to increase the optimization of this process. They created technology for this. Hyper-Threading, allowing one core to execute multiple threads simultaneously. For example, we have a processor with a 2-core chip that supports Hyper-Threading technology, then we can consider this processor as a quad-core one.

Turbo Boost

Previously, processors worked at one clock frequency, which was set by the manufacturer; to change this frequency to a higher one, people worked overclocking (overclocking) processor. This type of activity requires special knowledge, without which you can cause colossal damage to the processor or other computer components in a couple of moments.

Today, everything is completely different. Modern processors equipped with technology Turbo Boost, which allows the processor to operate at a variable clock frequency. This increases the energy efficiency and operating time of, for example, a laptop and other mobile devices.

Cache size

Processors typically work with big amount data. The operations performed may vary in size and complexity, but it often happens that the processor needs to process the same information several times. To speed up this process, and especially the processor itself, such data is stored in a special buffer (cache memory). Therefore, the processor can retrieve such data almost instantly, without unnecessary load.

The amount of cache memory in different processors is calculated differently. For example, in a low-end processor - 3-4 MB, and in higher-end models - 6-12 MB.

Of course, the more cache memory, the better and faster the processor will work, but this instruction is not suitable for all applications. For example, photo and video processing applications will use a large amount of cache memory. Therefore, the larger the cache size, the more efficient applications will run.

To perform simple tasks such as surfing the Internet or working in office programs ah, the cache is not that significant.

Intel processor types

Now let's look at the types of processors, namely the description of each of them.

Intel Core i3

What is it suitable for?: Normal, everyday work with office applications, watching the Internet and movies in high quality. For such processes, Core i3 is the best option.

Characteristic: This processor offers up to 2 cores and supports Hyper-Treading technology. True, it does not support Turbo Boost. Also, the processor has a fairly low power consumption, so this processor is undoubtedly suitable for laptops.

Intel Core i5

What is it suitable for?: More intensive work, such as using video and photo processing programs, many modern games can be played at low, medium and sometimes high settings.

Characteristic: This processor is used in both conventional desktop computers and laptops. It has from 2 to 4 cores, but does not support Hyper-Treading, but does support Turbo Boost.

Intel Core i7

What is it suitable for?: This processor is predisposed to work with powerful graphic editors. You can play modern games at maximum settings, but other components, such as the video card, also play a big role here. You can also view video files in 4K.

Characteristic: On this moment, this chip is the highest grade. It has both 2 and 4 cores and support for Hyper-Treading and Turbo Boost.

We have reviewed brief characteristics 3 types of processors, and now you can choose the best one for you.

After the announcement of the LGA1155 platform, Intel is methodically updating its processor lines. Starting with top CPUs, the manufacturer transfers to Sandy Bridge and more affordable solutions - Core i3 and Pentium. The latter are intended for entry-level and mid-level systems. Models costing “about $100” have always been objects of close attention from users who are accustomed to looking for the best options when completing a system. Often people who choose a processor from this price category approach this issue even more responsibly than those who are willing to pay any price for maximum performance. Let's see what the new Intel products are capable of in comparison with their predecessors and alternative solutions from their main competitor.

From a technical point of view, the most important difference between the Core i3 and the Core i5/i7 chips is that they are initially based on a dual-core crystal, and not a quad-core one with deactivated computing units. That is, no tricky tricks with unlocking will work here, however, Intel chips have not provided such an opportunity before. The area has decreased from 216 to 131 mm2, therefore, significantly more workpieces are obtained from one silicon wafer, and the cost of their production is lower. Accordingly, Intel has a chance to offer interesting retail prices, continuing to make money even on budget processors.

What changes have occurred in terms of functional equipment? The amount of L1 and L2 cache memory is identical for all models on Sandy Bridge (64 KB and 256 KB per core), but the third level buffer in the Core i3 has decreased in proportion to the number of cores - from 6 to 3 MB. The compact crystal, made using 32-nanometer technology, allows you to count on good power consumption indicators. TDP for the second generation Core i3 is 65 W, while its predecessors from the Clarkdale family this parameter was within 73 watts.

The chip integrates Intel HD Graphics 2000 with 6 computing units. The standard frequency of the video core is 850 MHz, while during operation it can dynamically increase to 1.1 GHz. Support for Quick Sync, a powerful tool for video transcoding, is retained. Another advantage of the Core i3 is Hyper Threading technology, which adds a couple more virtual cores to two physical cores. In multi-threaded applications, this function sometimes plays a very important role, allowing you to use CPU resources more efficiently. We also note that the processor has the ability to execute instructions from the AVX (Advanced Vector Extensions) set, which, with the proper degree of optimization, will help speed up floating-point calculations, which are actively used in multimedia software.

Alas, Core i3 does not support Turbo Boost technology for dynamically increasing the frequency of processor cores, which is to some extent compensated for by high nominal values. Given the positioning of the CPUs of this family, there are also no AES encryption instructions here.

The current line of processors consists of four models. The younger Core i3-2100 with a clock frequency of 3.1 GHz is offered for $117. The Core i3-2120 operates at 3.3 GHz and costs $20 more. Intel has also included a cost-effective version of the i3-2100T with a TDP of 35 W. As a rule, it is possible to reduce CPU power consumption by reducing the operating clock frequency and supply voltage. On motherboards that allow the user to perform downclocking themselves and reduce the voltage below the recommended values, it is often possible to achieve similar results. But in cases where this is not possible, purchasing energy-efficient models will be justified. The Core i3-2100T operates at 2.5 GHz, and the graphics unit frequency is reduced from 850 to 650 MHz, while it can dynamically increase to 1.1 GHz.

Chips with reduced power consumption will be in demand for systems with compact cases that have a small volume and, accordingly, limited options for choosing a cooling system.

The Core i3-2105 stands out in the series. This model has identical clock speeds to the i3-2100, but differs from other devices in the family in the use of more powerful Intel HD Graphics 3000 graphics. Returning to the chip topology, we note that the graphics component occupies a significant part of it - about a quarter. In turn, the lion's share of space is allocated to computing units. Therefore, taking into account the fact that most budget models will have built-in HD Graphics 2000 with 6 blocks, not 12, Intel developers rightly considered that simply deactivating half of the computers is not a very rational solution. Therefore, from a technological point of view, it turned out to be more profitable to have two designs of dual-core crystals. The version with more powerful graphics has a slightly larger area (149 mm2), but in terms of power consumption it also falls within 65 W. As we could see earlier, the performance of HD Graphics 2000 and 3000 is noticeably different: depending on the tasks, the latter is 1.5–2 times faster, while being a serious competitor to budget discrete video cards. An overpayment of $14 for a modification with faster graphics will make sense if you are determined to use integrated video, and the capabilities of HD Graphics 2000 seem insufficient for the intended tasks.

Unlike mobile solutions, where even dual-core processors can be offered under the Core i7 brand, among desktop Core models with Sandy Bridge architecture there is currently a fairly clear segmentation by the number of computing units (physical and virtual): Core i7 - 4 cores and Hyper Threading , Core i5 – 4 cores without HT, Core i3 – 2 cores and Hyper Threading.

Pentium

If we move down the conventional scale of differentiation of current Intel processors, Core i3 is followed by Pentium chips. With the advent of the Core architecture, without exaggeration, the legendary brand was used to designate fairly affordable CPUs with a traditionally good price/performance ratio. Modernization of this line has been asking for a long time. Recently, models for the still relevant LGA775 platform have not been easy to hold back the onslaught of inexpensive solutions from AMD, especially to compete on equal terms with the tri-core Athlon II X3, which often offered higher performance at a similar price. Pentium based on the Clarkdale core for the LGA1156 socket have not gained significant popularity. The market situation at the time of the release of this platform was such that it was primarily positioned by Intel as a solution for mid- and high-end systems. Therefore, even after expanding the initial range of processors, the minimum cost of admission here remained quite high. Retail price the most affordable Pentium G6950 is about $100, which is a bit expensive for a PC entry level. It is easy to assume that Pentium for LGA1156, combining two crystals (CPU and GPU), has a higher cost. Therefore, it is quite difficult to seriously reduce the price of these processors. Moreover, in this case we are talking about budget chips of mass production. And boards cheaper than $80–90 for LGA1156 actually appeared only after the announcement of Sandy Bridge.

The updated Pentium modifications were the result of a simple simplification of the dual-core chips used for the Core i3. First of all, Pentium lost Hyper Threading technology, as well as the ability to execute AVX instructions. At the same time, the cache memory volumes are identical to those for the Core i3. The new Pentium family chips also use Intel HD Graphics 2000, although with a number of restrictions regarding support for proprietary technologies. In particular, Quick Sync, the Intel Clear Video HD visual enhancement function and stereoscopic image output (Intel InTru 3D) do not work here.

At the initial stage, the line includes four models: Pentium G850 (2.9 GHz), G840 (2.8), G620 (2.6 GHz) and G620T (2.2 GHz). As you might guess, the latter refers to economical modifications, the energy consumption level of which does not exceed 35 W. In addition to the clock frequency reduced to 2.2 GHz, like the energy-efficient Core i3-2100T model, it also has a reduced graphics core frequency to 650 MHz with a limit value of 1.1 GHz.

As you can see, the new Pentium processors, in comparison with the Core i3, are mainly lighter in terms of functionality, while basic characteristics must provide a decent level of performance. The Sandy Bridge microarchitecture used promises a good increase in performance, which we will try to verify during practical tests. As for the price, in wholesale quantities the cost of the CPU family lies in the range of $64–86. The retail price will be slightly higher, but it is obvious that Pentium will be cheaper not only than the Core i3, but also its predecessors with the Clarkdale core.

The updated Pentium models were presented quite recently - at the end of May. And almost immediately they appeared in retail sales in Ukraine. Intel has a good practice of bringing its products to market when they become available to customers either simultaneously with the global presentation or as soon as possible after it.

Overclocking

Overclocking is a fairly popular pastime for many enthusiasts. Someone is trying to increase system performance in this way in the hope of delaying the next upgrade. For some, it is a hobby, a sport, or a way to satisfy idle curiosity by exploring the capabilities and hidden potential of the CPU.

Unfortunately, those who like to experiment with overclocking will be a little disappointed this time. Considering the specifics of the clock generator in the new platform and the locked processor multiplier of the chips reviewed, it is obvious that the room for maneuver here is seriously limited. Even despite the relatively high multiplication factors (+100–150 MHz), this is all that can be squeezed out after increasing the carrier bus to 103–106 MHz, at which current motherboards maintain stable operation. Of course, these are not the indicators that we would like to get, especially considering that older Sandy Bridge models often reach frequencies of 4500 MHz and higher even in the air. Alas, the new Pentium and Core i3 are not designed for overclocking at all. You will have to come to terms with this fact and take it into account when purchasing. At the same time, it is also important not to forget that these chips, even in normal mode, are noticeably more productive than their predecessors, which can even out the difference in frequencies.

In our opinion, you can’t expect modifications with unlocked multipliers among Core i3 and Pentium. Models with the K index, so beloved by overclockers, will be available only in the more expensive Core i5/i7 lines.

Results

As the test results demonstrate, the new Intel processors in the mid-price category have a noticeable performance advantage over their predecessors in terms of performance. Under conditions of good multi-threaded program optimization, AMD chips with a large number of physical computing units can sometimes provide serious resistance. For example, if you look at the performance of the Athlon II X3 455 and Pentium G620, which are now offered at approximately the same price, then a triple-core CPU in applications where calculations can take place in parallel has a definite advantage. Even though the core speed in terms of megahertz of AMD products with K10.5 architecture is noticeably lower than that of Intel chips on Sandy Bridge, in such software “brute force” is often quite effective, although this is achieved by increasing energy costs by one and a half times. However, we must admit that this is an ideal case when all processor cores are used as efficiently as possible. In real applications, this does not happen often, unfortunately. In games, new ones have unconditional primacy Intel solutions. As we have already seen, the Sandy Bridge microarchitecture copes well with such loads, and the gap between both its predecessors and competitor models is maximum.

New Pentiums are on average 20% more productive than CPUs of the same name for LGA1156 and compete almost equally with Core i3 on the Clarkdale core, which are noticeably more expensive. Simplification of the functional part of these chips did not greatly affect their speed performance. Therefore, these models can be fully recommended for creating universal systems and entry-level gaming platforms. In turn, the second generation Core i3 also noticeably accelerated. Of course, it’s difficult for them to compete with quad-core Core i5s, but high clock speeds and support for Hyper Threading technology allow them to demonstrate very decent results, including in applications with multi-threaded optimization. Well, in games they sometimes look preferable to the quad-core AMD Phenom II X4. Considering that these processors have retained the functionality of older models, they may be interesting for creating both mid-level gaming PCs and powerful multimedia systems.

This time, Intel has done everything to make the LGA1155 platform truly universal. The existing infrastructure allows you to create both a top-end system and an inexpensive entry-level PC. For powerful configurations, there are enough motherboards on the market based on Intel Z68 and P67 chips, and for the most affordable solutions, it is quite possible to use models based on Intel H61. Intel's processor line now looks very smooth. There are no distortions or obvious competition between solutions from different families. So far, one brick is missing - the most affordable CPU models. Soon, Celeron is also planned to be transferred to the 32-nanometer process and a progressive microarchitecture. Presumably, these chips will appear in the third quarter of this year, at which time the range of other lines on Sandy Bridge will be expanded.

Test bench configuration

Intel, www.intel.ua

Hello, dear subscribers of our blog. Today I will try to explain how the i3 processor differs from the i5. Surely many people are interested in why one Intel Core costs so much more than another, although you won’t immediately understand what the point is. In this article we will analyze which stone is best suited for PC games and work tasks.

The comparison will be multi-stage and contain summary tables. By the way, in the second part we will look at and also advise which one for certain tasks.

I would especially like to say that mobile processors we don’t mention it specifically - everything is much more complicated there, and besides, special attention is paid to labeling rather than numerical value chips and characteristics.

Difference between Coffee Lake and previous generations

The release of the 8th generation of Intel Core literally put the entire computer hardware market on edge. The difference between previous generations is colossal, and is expressed in the following figures:

Characteristic	Core i3 (2–7)	Core i5 (2–7)	Core i3 (8)	Core i5 (8)
Number of physical cores	2	4	4	6
Level 3 cache	3 MB	8 MB	6 MB	9 MB
Hyper Threading support	+	-	-	-
Turbo Boost support	-	+	-	+
Memory support	DDR-2400	DDR-2400	DDR-2400	DDR-2666
Unlocked multiplier	-	+	+ (8350K)	+
Socket	1151	1151	1151v2	1151v2

As you can see, the usual concept has changed radically, as well as the technical characteristics. This was facilitated by the release of AMD Ryzen, which included 4 computing cores (Ryzen 3 1200) in the minimum configuration.

I'm glad that the built-in video remains, as do most proprietary technologies and instructions. Another thing is that the quality of graphics has not changed compared to Kaby Lake - still the same Intel UHD 630.

Difference between i3 and i5

First, let's look at the classic confrontation between processors, and then switch to the more recent Coffee Lake. The confrontation scheme will include several points.

• Number of Cores

The more physical cores, the more operations the chip performs per clock cycle. For i3 this indicator is 2, for i5 – 4, respectively.

For Coffee Lake the situation is as follows: both chips added 2 physical cores, but i5 is still the leader in this area.

• Turbo Boost

This technology allows you to significantly increase the CPU frequency in automatic mode only in cases where it is really necessary. In essence, this is a “lazy” version of overclocking by a multiplier, which is limited by the limitations of the platform, heat package and cooling. Only i5 has this mode, when i3 has fixed frequencies.

• Hyper-Threading

For processors, one physical core usually receives one stream of data, which is processed by this core. This function (i.e. HT) allows you to use 2 threads per core at once.

Many people mistakenly believe that virtual cores are almost identical to physical ones, but in fact the processor performs one operation not with one, but with two hands, to put it as simply and intelligibly as possible.

Second, third, fourth and even seventh generation i3 processors supported this function, but with the advent of Coffee Lake, the number of physical computing units increased from 2 to 4, and the need for the technology disappeared. Core i5s do not support the mode natively.

• Cache size

Popularity Intel series The 8th generation Core i3 is mainly based on the Core i3-8100 model, which offers full 4 cores with a frequency of 3.6 GHz for an average of $120. If you spend approximately $45, you can take the Intel Core i3-8300, which has a frequency of only 100 MHz higher and a faster video core. And for IntelCore i3-8350K you will have to pay an average of $185, although a dilemma already arises here, since by adding another $25, you can get a 6-core one.

What is interesting about the Core i3-8350K and why is it so far removed from the Core i3-8100? First of all, its base frequency is 400 MHz higher, that is, at nominal we get 4 instead of 3.6 GHz. But the main thing is that its multiplier is unlocked, and this opens the way for overclocking experiments. In addition, the thermal package has been increased from 65 to 91 W. Secondly, it has 2 MB more L3 cache. And thirdly, we can remember about a more productive video core, if someone is interested in it.

As a result, the Intel Core i3-8350K is designed for fans of overclocking experiments, gamers, traders, scientists and other professionals for whom high performance in single-threaded mode is important, and not the presence of a large number of cores.

Packaging, delivery and appearance

The processor comes complete with documentation and a sticker. The cooling system will have to be purchased separately, which is quite justified for a model with overclocking potential, but this will additionally increase the cost of the final system.

The FPO code indicates that the CPU was manufactured in the Malaysian factory in week 29 of 2017. On the reverse side there are contact pads for the Socket LGA1151 connector. Let us remind you that processors from the Intel Coffee Lake line are officially compatible only with motherboards based on Intel 300 series chipsets. When using, you can try to run them on models with Intel 100 and 200 series chipsets, but no one gives guarantees of success.

Technical characteristics analysis

When running the stress test, the Intel Core i3-8350K reached the nominal speed of 4 GHz without any problems. Moreover, this frequency is stable and constant, regardless of the number of cores involved. For example, the same Core i5-8400 has a base speed of 2.8 GHz, and the dynamic speed varies depending on the number of cores: 3.8 GHz for six, 3.9 GHz for four and two, 4 GHz for one.

The distribution of L1 and L2 cache memory for the Core i3-8350K and other representatives of this series is similar, but L3 has 8 MB or 2 MB per core instead of 1.5 MB/core for younger models. In addition, 16 associativity channels are used instead of 12, which should also improve performance.

The RAM controller is guaranteed to support DDR4-2400 standard modules in dual-channel mode, although representatives of the Intel Core i5 and Core i7 series can operate with DDR4-2666 memory. If desired, this difference can be made up by overclocking. Moreover, it is unlikely that anyone will buy such a processor with a motherboard on lower chipsets.

And if you decide to use a processor without a video card, then you will have at your disposal an integrated graphics core Intel UHD Graphics 630 with a base frequency of 350 MHz and dynamic overclocking up to 1150 MHz. Unofficial sources indicate the presence of 23 execution units in its structure instead of 24 in older models of the Intel Core i5 and Core i7 series. If you're interested in iGPU gaming performance, it will be slightly better than the Intel Core i3-8100.

Testing

To test the Intel Core i3-8350K processor, as well as its internal and external competitors, the following stands were used:

CPU	AMD Ryzen 5 2600	Intel Core i3-8100 / Intel Core i3-8350K / Intel Core i5-8400

1. Comparison at nominal parameters. Synthetics

In general, the results for synthetics are quite predictable: the Intel Core i3-8350K outperforms the Intel Core i3-8100 by an average of 9%. In turn, both 6-core processors look better than the tested model.

2. Comparison at nominal parameters. Games

Let's summarize the first part. In the fight between 4-core processors, a natural advantage of 10-20% remained with the Intel Core i3-8350K.

In turn, the Intel Core i5-8400 proves that in nominal mode, gamers are better off paying extra for 6 cores, receiving a performance bonus of 20-24%.

Compared to the Ryzen 5 2600, the 4-core Core i3-8350K still came out the winner, although the difference is within 2-11%. However, in heavy games with an open world and optimization for multi-threading, it is the AMD representative that will look more interesting.

3. Overclocking comparison. Synthetics

Overclocking is always a kind of lottery, but in this case we were lucky, although luck would have been better in a real lottery. The processor really got something wrong, so under good cooling managed to accelerate it to 5 GHz. This is far from the limit, but the figure is beautiful and I didn’t want to tempt fate further. We saw results from our colleagues in the range of 4.5 - 4.8 GHz, and on HWBOT the record is 5.8 GHz.

During the overclocking process, the multiplier was increased to 50, and the CPU Core Voltage Override was manual mode raised to 1.36 V. At the same time, they increased the frequency of the RAM modules from 2400 to 3466 MHz by activating the XMP profile.

The system worked stably after reboot. The processor temperature did not rise above 77°C with a critical indicator of 100°C.

The remaining Intel representatives in this test lack overclocking potential. We were able to help these “patients” only by raising the RAM frequency to the same 3466 MHz.

In turn, it was possible to accelerate to 4150 MHz thanks to an increase in the multiplier, CPU Core Voltage and CPU NB/SOC Voltage, as well as the choice of the second mode for Loadline Calibration. After this, the system passed the stress test without any problems.

The memory worked at a frequency of 3.4 GHz using the same XMP profile.

What has changed after the overclocking? The gap between the Core i3-8350K and its younger brother increased from 9% to 27%, and the handicap of the Core i5, on the contrary, decreased from 24% to 4%. Even Ryzen 5 felt the high overclocking of the Core i3: its advantage was reduced from 39% to 22%.

4. Overclocking comparison. Games

As a result, without… statistics you can’t figure it out. Overclocking definitely benefited the Intel Core i3-8350K processor: its performance increased by 25-31%.

This allowed him to ride like a roller on his 4-core brother, ahead of him by 19-29%.

The Ryzen 5 2600 could not resist either, which after overclocking does not pose any danger to the Core i3-8350K, because they are separated by 16-37%.

But the Core i5-8400 turned out to be better than even the accelerated 4-core one, but only by 3-7%. Agree, this is already much more pleasant compared to the impressive 24% obtained in nominal mode.

Results

So, in nominal mode, the Core i3-8350K is not of particular interest to the average user: in synthetics it is only 9% better than the Core i3-8100, although in price terms they are separated by about 50%. For gaming, the slightly more expensive 6-core Core i5-8400 is better suited.

The situation changes after a good overclock. In games and synthetics, the advantage of the Core i5 is reduced to an average of 3-7%, but the worse the application uses many threads, the more effective the Core i3-8350K shows itself, and in some cases it will be significantly faster.
