Comparison with closest competitors
And although the processors on Kaby Lake have already come out, their tests are not yet available, so we will confine ourselves to the previous line, Skylake - from a technical point of view, the difference between them is small. For comparison, let's take three processors - Intel Atom x7-Z8700, as one of the most powerful representatives of the Atom line, Intel Core m3-6Y30 - the weakest Core m (I'll explain later why you shouldn't take more powerful ones), and Intel Core i3-6100U - a popular representative of the weakest line of "full-fledged" low-voltage processors: It turns out an interesting picture - from a physical point of view, Core m3 and i3 are absolutely identical, only the maximum frequencies of the graphics and processor differ, while the thermal package differs threefold, which, in general, cannot be. The Atom has the same TDP as the Core m3, comparable clocks, but 4 physical cores. At the same time, although there are more cores, they are greatly reduced in terms of capabilities to reduce heat generation: for example, an i5-6300HQ with 4 "full" physical cores with the same frequencies has a TDP an order of magnitude higher - 45 watts. Therefore, it will be interesting to compare the capabilities of the stripped-down and full-fledged architectures with the same heat dissipation.
Processor tests
As it was already found out above, m3 is essentially i3, clamped three times smaller heat pack. It would seem that the difference in performance should be at least twofold, but there are several nuances here: firstly, Intel allows Core m not to pay attention to TDP until its temperature reaches a certain point. This is very clearly seen when running the Cinebench R15 benchmark several times:
As you can see, the processor gained about 215 points in the first 4 test runs, and then the results stabilized at 185, that is, the performance loss due to such "cheating" by Intel was about 15%. Therefore, it makes no sense to take more powerful Core m5 and m7 - after 10 minutes of load, they will reduce performance to the level of Core m3. But the result of i3-6100U, the operating frequency of which is only 100 MHz higher than that of the m3-6Y30, is much better - 250 points: That is, when only the processor is loaded, the difference in performance between m3 and i3 turns out to be 35% - quite a significant result. But Atom showed itself from the best side - although the cores are cut, but twice as many of them gave the processor the opportunity to score 140 points. Yes, the result is still 25% worse than the Core m3, but let's not forget about the eightfold difference in price between them. The second nuance is that the thermal package is designed for both a video card and a processor at the same time, so let's look at the results of the 3Dmark 11 Performance test: this is a test designed for a mid-range PC (which our systems belong to), testing both the processor and the video card at the same time. And here the final difference turns out to be the same, Core m3 turns out to be 30% worse than i3 (because Core i3 also ceases to have enough thermal package - it needs about 20 watts to work at maximum frequencies): Intel Core m3-6Y30: Intel Core i3-6100U: But Intel Atom fails with a bang - the result is 4-5 times worse than that of m3 and i3: And this, in principle, is expected - Cinebench tests the bare mathematical performance of the processor and is well suited only for comparing processors of the same architecture, but 3Dmark gives versatile load, much more close to real life. Still, the eightfold difference in price keeps the Atom afloat.
Energy consumption
As you can see from the tests above, a threefold difference in TDP gives a performance gain of about 35%. However, this is only true under heavy load, which is quite rare for ultrabooks. For convenience, let's take two MacBooks, 12 "and 13" 2016 - macOS on different devices optimized equally well, and this will allow you to find out the difference in power consumption of devices without reference to operating system(yes, below we test the power consumption of the entire system, but only screens and processors make a significant contribution to it, and since the former are very similar, only processors make a significant contribution to the difference in power consumption). And here the difference turns out to be ... only one and a half watts on average, 7.2 and 8.9 watts (moreover, a 13 "Macbook has a processor more powerful than i3-6100U): 
What does this mean? This means that under normal load, both processors consume only a few watts, and the Core m does not come to the TDP limit. Intel Atom shows power consumption comparable to Core m3 (for example, Microsoft Surface 3 is taken, which is well optimized for working with Windows):
What is the end result? Intel Atom is a good choice for an inexpensive tablet or netbook, on which no one will run anything heavier than 1080p60 from YouTube. The processor is cheap, and for that, it can be forgiven for the difference in performance with the Core lines. Intel Core m is a good choice for a performance tablet or a simple ultrabook. Due to the lack of a cooler, such a device will be absolutely silent, and in ordinary tasks it will be no slower than its more powerful counterparts on the Core i. However, it is clearly not worth taking it to process photos or videos, and even more so for games - the performance quickly runs into a low TDP and decreases quite dramatically even in comparison with a simple i3. Well, the Core i line is a good choice for a productive ultrabook. If there is at least simple discrete graphics in the system, such a device turns out to be at the level of gaming laptops 5 years ago, and allows you to easily deal with both photo and light video processing, as well as making it possible to play massive games even at not the most minimal graphics settings. However, any load above average will lead to a noticeable noise from a small high-speed cooler, which can annoy those who like to work in silence at night.

Intel Kaby Lake: New Core M3 Processor Announced
In fact, there are not many innovations. The new Core M3 is also manufactured using 14nm technology, contains two processing cores with the ability to process up to four instruction streams and supports LPDDR3-1866 and DDR3L-1600 memory. The integrated GPU Intel HD Graphics 615 with a frequency of up to 900 MHz (in the previous version it was 615) is responsible for graphics processing.
But in the new processor the frequency increased - up to 1.1 GHz in the base mode and up to 3.0 GHz in the "turbo" mode (earlier it was 1.0 GHz and 2.6 GHz, respectively). The processor emits only 4.5 watts of thermal power (TDP). According to the manufacturer, this value can be reduced to 3.75 W in order to improve energy efficiency.
Recall that the Core M3 series of processors are usually used in fanless devices and energy efficient portable computers - laptops, tablets or convertible tablets. The processor price is $ 281.

Intel Core M preview
With the release of the Core M processors, Intel has prepared replacements for the energy-efficient versions of the Core i3 and Atom chips commonly found in thin laptops, tablets, and 2-in-1 hybrid mobile devices. M are content with only 4.5 watts of power.
This allowed not only to increase the duration autonomous work mobile devices, but also to reduce the thickness of their body. According to Intel, a passive cooling system is sufficient to remove heat from most models of new processors, so mobile computers equipped with the new chips run silently.
Lenovo Yoga 3 Pro: one of the first Ultrabooks based on Core M
However, some devices use active coolers, such as, for example, in a multi-mode ultrabook Lenovo IdeaPad Yoga 3 Pro. But this does not help: some gadget owners complain about overheating and decreased performance. For example, the frequency of the Core M-5Y70 processor installed in the Lenovo IdeaPad Yoga 3 Pro can reach 2.6 GHz in the automatic Turbo Boost mode, but the gadget is capable of holding it for only 10 seconds. After that, the processor goes into throttling mode to protect against possible thermal damage. Since newer processors have an integrated graphics core, overheating of the processor cores will reduce the performance of the graphics subsystem.
Ordinary consumers are unlikely to appreciate the benefits that new line Intel Core M microprocessors, since devices based on new chips are expensive (the average retail price of Yoga 3 Pro according to Yandex.market is 114,000 rubles) and offer a low level of performance for their money.
The advantages of the Core M series processors are different: low power consumption and low heat generation made it possible for engineers to design very light and thin laptop computers. For example, the 13.3-inch Yoga 3 Pro weighs just 1.19 kg and is only 12.8 mm thick. Compared to Intel Atom, the new chips offer a higher level of performance and support Trusted Computing, vPro and other technologies aimed at business users.
Intel Core M test results
Since the Core M-5Y70 processor installed in the tested Lenovo Yoga 3 Pro, often overheated, we asked the manufacturers for something else mobile device, in which the less efficient Core M-5Y10 chip is installed. The rivals were Core i3-4158U and Atom Z3735F.
In PCMark 7 benchmark suite, which measures performance personal computer in solving a wide range of tasks, including web surfing, video playback and working with documents, a mobile computer with a Core M-5Y10 chip scored 12,045 points. The device based on the Core i3-4158U managed to surpass this result by only 320 points, while the quad-core Atom Z3735F was twice as slow (5730 points). Unfortunately, the latter refused to work in the Cinebench R15 test suite. The Core M and Core i3 deliver nearly identical performance levels.
Late last year, Intel introduced the first of its fifth generation (Broadwell) processors with three models in the Intel® Core ™ M family. This developer article describes this 64-bit multi-core processor System-on-a-Chip and describes the Intel® technologies implemented in it, including Intel® HD Graphics 5300.
The Intel® Core ™ M processor family delivers better performance with a smaller footprint, reduced power and cooling requirements (great for thin, fanless devices), and longer battery life. Processors support the following technologies:
- Intel HD5300 Graphics and Intel® Wireless Display 5.0;
- Intel Wireless-AC 7265 and support for wireless docking (in 2015) using WiGig;
- Intel® Smart Sound Technology;
- Intel® Platform Protection Technology and other security features.
Key Features of Intel Core M Processors
Downsize + Increases Performance = Reduced Power and Cooling RequirementsIntel Core M are the first processors to be manufactured using 14nm technology. The size of the silicon chip has been reduced by more than 30%, although the number of transistors has increased by more than 300 million. Intel Core M processors have lower power consumption and generate less heat. The three models of this family, which began production in the 4th quarter of 2014, have a thermal power of only 4.5 W. This means that no fan is needed to cool these processors. These processors will allow you to achieve high performance in the thinnest devices (less than 9 mm thick), including tablets and transformers.
Figure 1. Comparison of Intel Core M Processors with Lower Power Consumption
The graph on the left in Fig. 1 shows a decrease in thermal power from 18W in 2010 to 4.5W in an Intel Core M. This is a fourfold decrease in 4 years and a 60% decrease compared to 2013. On the right in Fig. Figure 1 compares the dimensions of the 4th Generation Intel® Core ™ processor with the new Intel Core M processor. By reducing the processor footprint by about 50%, the processor footprint has been reduced by about 25%.
Intel Core M processors by their own overall dimensions fewer 4th generation Intel Core processors. In this case, two Intel Core M cores are provided with a cache of 4 MB. Intel® Hyper-Threading Technology supports four simultaneous threads. With Intel® Turbo Boost Technology 2.0, cores can be boosted from 0.8 GHz to 2 GHz,
and for Intel Core M 5Y70 processors - from 1.1 GHz to 2.6 GHz.
Figure 2. 2014 Intel Core M Processor Models
The CPU, GPU, memory controller, sound controller and network interfaces are implemented in a single chip with 1.3 billion transistors, so you should not expect performance degradation. Moreover, comparison with the previous generation Intel® Core ™ i5-4320Y processor showed significant performance gains.

D about the official release Intel Kaby Lake almost a stone's throw away. This event is expected on August 16-18 at IDF 2016. But Chinese sources already allow making bets on changes in new generations of processors against the background of old ones.
So, the series Core M(aimed at extremely thin and light tablets and laptops, usually with passive cooling) can suffer losses. The combination of price, performance and power consumption of the first and second generation of these processors did not suit either manufacturers or users, although it was a serious step forward against the background of Core Y or Atom / Pentium / Celeron. Now more and more companies are choosing by hook or by crook to use 15-watt Core i5 models instead of 4.5-watt Core m3 / m5 / m7, fearing a drop in new device sales amid growing customer distrust of the Core M brand. To remedy the situation, Intel can:
A) Rename Core m5 and Core m7 processors. Then the third Core generation M will refer to the Core i5 or Core i7 series, which are now inhabited by exclusively "full-fledged" models with a thermal package of 15 W, 28 W and higher. Such a move would be analogous to an attempt to outwit the customer, who looks only at the left side of the processor name (denotes a family), but not at the right. It is there, on the right, that the letter Y remains, so as not to create final confusion (an example of such a "cunning" name: Core i5-7Y54.) Only the most inexpensive and weak Y-class processors will be left as is (example:Core m3-7Y30.) Probably, the selling price of all the third generation Core M will be identical to the price of the old (second generation) or even less.
Estimated characteristics of the new processors:
- Core m3 7Y30 (1.0 - 2.6 GHz, Intel HD Graphics 615)
- Core i5 7Y54 (1.2 - 3.2 GHz, Intel HD Graphics 615)
- Core i7 7Y75 (1.3 - 3.6 GHz, Intel HD Graphics 615)
B) If the first option is not confirmed or does not give an effect, later on you can completely abandon the Core M processors. In its strategy, Intel focuses primarily on its customers, large companies, and they just express dissatisfaction with these processors. The most prominent Core M devices are the latest Microsoft Surfaces as well as the 12-inch Apple MacBook... And then, and this can be translated to Core i3 and Core i5, taking into account the possibility of reducing their thermal package by limiting frequencies. And we also need to see what Apple does with the laptop series. MacBook Air, this point should become clear in the second half of the year. In case of refusal from Core M Intel you will have to reconsider your attitude towards the Atom, Celeron and Pentium brands, which are now successful only in the cheapest consumer devices. ©

The data is obtained from tests of users who have tested their systems both with and without overclocking. Thus, you see the average values corresponding to the processor.
Speed of numeric operations
Different tasks require different strengths CPU. A system with a small number of fast cores is great for gaming, but will yield to a system with large quantity slow cores in a render script.
We believe that a processor with at least 4 cores / 4 threads is suitable for a budget gaming computer. At the same time, individual games can load it by 100% and slow down, and performing any tasks in the background will lead to a FPS drawdown.
Ideally, the buyer should aim for a minimum of 6/6 or 6/12, but keep in mind that systems with more than 16 threads are currently only applicable for professional tasks.
The data was obtained from tests of users who tested their systems both in overclocking (maximum value in the table) and without (minimum). The typical result is shown in the middle, the color bar indicates the position among all tested systems.
