Modern Intel ® Coretm desktop processors are traditionally divided into two groups: “normal “and”for enthusiasts”. And although Real buyers are guided by this placement not always, it describes well what can be expected from a particular chip.
Processors for fans, which are labeled with the letter K in the name, are overclocking models with unlocked multipliers, high clock speeds and inflated heat packet frames. Of course, these tips are designed for more experienced users, so it’s not a problem to set up the system for a huge number of different options and choose the right range of accessories, which includes the right motherboard, worthy of power and efficient cooling system.
The processors that Intel supplies to ordinary users are smaller, but they are slower and cheaper. These processors are designed to cause a minimum of problems for end users: they typically do not require any system-specific settings, and the plug and play principle works. In addition to the fact that such CPUs do not allow access to the change of the multiplication factor, they also have more discrete frequencies and low consumption, which allows you to complete your relatively simple cooling systems and not worry about the selection of plates and other strapping.
Surprisingly, processors belonging to different groups often have almost identical model numbers, although it is obvious that their performance and other consumer qualities can vary very seriously. And this is especially noticeable in the generation of Comet Lake. In IT, CPU overclocking models significantly increased their power appetites and got the characteristic of a typical heat dissipation to 125 watts. Processors for conventional systems continued to exist within a typical 65-watt thermal package for this class, that is, their consumption and heat dissipation were almost twice less than those of the overclocker brothers. And still together with the Core i9-10900k there is a Core i9-10900, next to the Core i7-10700k provided Core i7-10700, and instead of Core i5-10600k you can buy Core i5-10600.
Coexistence, on the one hand, similar, but with another – very different models made us think about the need to conduct a special test, which could have shown how big the difference between them and how they should be treated when filling the model of the 10th generation Core processor series. This interest is largely fueled by the fact that “simple” models do not seem useless even to advanced users. On the one hand, they are 10-20% less, but they offer exactly the same number of cores and threads as overclocking flagship models. On the other hand, its basic clock frequencies are less than a full gigahertz, which will certainly make a frightening impression on an inexperienced user.
But even if there are significant differences in nominal frequencies and they have real weight, this is not a reason to deliberately put a cross on the “no-k”models. First of all, a fairly positive message for a considerable part of users can bring their cost immediately indicated in the specifications. Secondly, if you look at the maximum models турбочастоты “normal”, then the situation with the frequencies no longer seems so terrible, because for this characteristic advantage оверклокерских versions with TDP of 125 watts is only 100-300 Mhz.
In this article we will try to give a clear answer to the question that will be faced by those who choose the processor system without index “K” in the title: if with multicore CPU, with no more impressive performance, where in the foreground it is given to energy efficiency, both with reduced costs and only a slightly slow version of the tip, both in general As part of a partner project, Intel provided us for detailed research the Core i7-10700 processor, a promising Octa-core
Core i7 – 10700 in detail
Speaking of the Core i7-10700, let’s say you are familiar with the flagship Intel Octa-core for the LGA1200 platform-the Core i7-10700k processor. if not, we strongly recommend that you refer to the appropriate review on our site.
The fact is that if you remove all overclocking capabilities, the Core i7-10700 without the K index turns out to be a very close relative of its overclocking companion. At least both are based on the same silicon, which means that the differences between the two exist only at the level of clock speed and thermal and energy performance. In general, the Core i7-10700 is an octa-core processor based on the Skylake microarchitecture with support for Hyper-Threading technology, which has an L3 cache of 16 Mbytes. It is built on a stepping Q0 semiconductor crystal, which is made of 14-nanometer process technology (with a number of more characters), and initially has 10 cores, a couple of which are hardware-locked and inefficient. In this key property Core i7-10700-economy: its double heat package more stringent than the Core i7-10700k and heat dissipation installed at 65 Watts.
Speaking of the Core i7-10700k, we made close parallels between the Core i9-9900K and the Core i7-10700 of the previous generation. following this logic, I want to say that the Core i7-10700 is the ideological heir to the 65-watt Core i9-9900, and it is almost true. However, there is a rarity: while the overclocking Core i7-10700k in operating frequencies slightly exceeds the Core i9-9900K, the normal Core i7-10700, on the contrary, is slightly inferior to the predecessor for the LGA1151v2 platform.
The logic is that if the latest generation of processors Core i9 – 9900k and Core i9-9900 were as close as possible to one another by a formula of frequency, formal, and the difference between the two was the size of the TDP, in the generation Comet Lake, Intel has removed the Core i7 – 10700k and Core i7-10700 one another, in particular, and frequencies. It is for this reason that the Core i7-10700 looks a little less interesting in the context of the Core i9-9900.
However, do not forget about the nuances. The maximum frequencies that processors can develop in Turbo mode, Core i7 – 10700 and Core i9-9900 are configured with a space of 100-200 MHz.
In fact, with short-term loads lasting less than 28 seconds, the Core i7-10700 has the ability to run smoothly at its maximum turbo frequency. The PL2 limit of 224 W if it is able to somehow affect the frequency formula, the impact will be extremely insignificant. A kind of tangible slowdown of the Core i7-10700 can occur only when a serious load on the processor will be of a long and continuous nature.
As it appears in practice, you can see the following table. In it, we showed the actual frequencies and power consumption of the Core i7-10700 while running the rendering test on Cinebench R20.
The first 20 seconds of the Core i7-10700 test run smoothly at the maximum frequency of 4.6-4.7 GHz. Its power consumption at the same time reaches about 150 W, but it is-within the framework of the rules, because it does not go beyond the border PL2. – 65-ваттному CPU consumption comes only after some time, and, in order to meet the specifications and not go beyond the PL1 limit, its frequency is restored to 3.6-3.7 Ghz, that is, by 20-25%.
That said, it is very important that all the consumption limits described by the specifications for the Core i7-10700 are not really mandatory. Even if the processor and does not refer to the number of оверклокерских, and the multiplication factor is impossible to improve, changing the consumption limits manually for him is not forbidden to the settings available in the BIOS virtually any motherboard. As a result, users, so it is not necessary to limit power consumption, can easily configure Core i7-10700 so, for him, driven only frequency formula турборежима, ignoring all passport limitations of heat dissipation, and power consumption.
It turns out that the Core i7-10700-this is the case, when we can talk about a processor, two in one: or efficiency, if you follow all the specifications and to meet the limits PL1 and PL2, or rather animated, if these limits were. As a combination of these two entities is shown in the table below, where indicated in the nucleus of frequency i7 – 10700 on a test render Cinebench R20: in a case-always for cpu included a certain specification 65-ваттное limit, and the other capable of missing parts out of PL1 and PL2.
Of course, all this affects performance. Operating without limits, the Core i7-10700 earns about 4890 points on Cinebench R20, but in a state of energy efficiency of 65 watts, this figure drops to 3880 points.
All this leads us to the conclusion that the Core i7-10700 this is not similar to the Core i7-10700k, which, if activated, the power consumption limits PL1 and PL2 loses in performance only slightly. About Core i7-10700 this is impossible to say: the inclusion of power consumption limits makes it completely different from the point of view of practical characteristics of the CPU. The yield, judging by the Cinebench R20, is reduced by about 20%.
What is obtained by comparing the actual consumption of Core i7-10700 in two configurations is shown in the following table, which is based on measurements on Cinebench R20 with different limits on the number of active threads.
