Albeit with a slight delay, Samsung presented new processor Exynos 7872. 14 nm chipset is aimed at the budget and mid-market segment. We have already become familiar with its characteristics, since it was announced on the same day Meizu smartphone M6s was released on this platform. In this publication, we take a closer look at the interesting chip and study its technical parameters in detail.

Hertz, cores, technical process

The Exynos 7872 processor is manufactured according to the standards 14nm technical process. Accordingly, smartphones on the new platform will be characterized by slight heating under load and fairly careful battery consumption. A parallel with the Snapdragon 630 suggests itself, but it will not be entirely appropriate, since the chipset has a fundamentally different core configuration.

In Exynos 7872 processor six cores, and not the eight familiar to our eyes. Four cores- reference ARM Cortex-A53, which operate at a frequency 1.6 GHz. Clock frequency The energy efficiency of the cores is low, which, like the technical process, adds whists to the autonomy column. Two cores built according to architecture Cortex-A73. These cores operate at a frequency 2 GHz and are responsible for solving complex computing problems. They will determine the maximum performance of phones on the new platform.

Note that the appearance of fast Cortex-A73 cores in the budget segment (the same Meizu M6s falls into this market segment) is a very positive signal. This could significantly change the balance of power and raise the performance bar for low-cost smartphones.

The results of the M6s in the popular AnTuTu benchmark have already appeared online. The overall score (88133) is noticeably higher than that of smartphones based on Snapdragon 625/630. CPU speeds are approximately three times higher, all thanks to Cortex-A73 cores. True, speed graphics adapter at the Dragon level.

Graphics accelerator: Mali-G71

A familiar adapter is used as a graphics accelerator Mali-G71. Let us remind you that this is the graphics installed in last year’s Huawei flagships P10 and Galaxy S8/S8+. However, it is again not worth drawing direct parallels. In Huawei P10, the graphics chip has eight cores, in Galaxy S8/S8+ there are twenty.

A chip for the budget segment will, of course, have fewer cores, which will inevitably affect performance. For smartphones with FullHD resolution, the power may not be enough. (For example, there is a 3-core accelerator).

It is appropriate to note here that we will not see phones with FullHD+ resolution on this chipset. The maximum screen resolution supported by the Exynos 7872 processor is 1200x1920 pixels.

Other chipset characteristics

RAM can only be LPDDR3, which certainly slightly limits the potential of this processor. The obvious disadvantage is flash memory eMMC 5.1, not UFS. Another factor that somewhat limits the performance of smartphones powered by the Exynos 7872 processor.

Wireless communication is assigned to an LTE modem of the seventh category (300 Mbps download, 150 Mbps upload). The Wi-Fi module supports the a/b/g/n standards, but does not support the ac standard. Bluetooth 5 supported.

The Exynos 7872 processor makes it possible to implement biometric user identification in a smartphone based on the pattern of the iris., which for a long time remained the prerogative of flagships. Phones will not be able to record video in 4K format; the limit of capabilities is 1080p at 120 frames per second.

That's all for us. If you find an inaccuracy in the material, write to us and we will correct it. Thank you in advance.

Unlike Qualcomm, Samsung doesn't get a lot of attention when releasing new processors. However, chip production is an important business for the company. Mobile Samsung processors work in a variety of Galaxy smartphones, starting with the flagship “S” line, ending with the budget “J” line. Today we will learn more about these processors.

Exynos for flagships

Flagship Samsung smartphones sold in two versions for different markets. One version runs on an Exynos processor, the other uses a Qualcomm processor. In the case of the Galaxy S9, one device received an Exynos 9810, the other a Snapdragon 845.

Samsung is the only manufacturer of smartphones under Android control, whose processors are built on a proprietary architecture called Mongoose. The Exynos 9810 processor is built on the third generation of this architecture. Samsung's approach is somewhat similar to what Apple is doing. Samsung M cores use more cache and are more efficient, but there are efficiency issues.

Exynos 9-series processors are built using 10nm technological process. They are equipped with the fastest LTE modems, support dual camera With high resolution, as well as LPDDR4X RAM and UFS.

Exynos for mid-range smartphones

The most advanced chip for mid-range smartphones price segment from Samsung is Exynos 9610. On this moment it is not used in any smartphone. Exynos 7885 is designed for the 2018 Galaxy A line of smartphones. These chips do not use Samsung M cores. Instead, they use ARM Cortex-A73 and Cortex-A53.

You can compare the more affordable Exynos with the Snapdragon 710 processor and the Snapdragon 600 series chips. Exynos processors do not lose in anything.

Exynos for budget smartphones

Budget Samsung smartphones run on Exynos fifth series and Exynos seventh series. These processors are used in last year's Galaxy A5 and Galaxy J3. These processors still feature a fast LTE modem, but they are built using a 14nm process technology.

You can't call them boring. For example, Exynos 7822 uses six cores. Two Cortex-A73 cores provide high performance, and four Cortex-A53 cores are energy efficient. Support for LPDDR3 and simpler camera options makes these chips affordable. They can be compared to Qualcomm's Snapdragon 450.

Rumor has it that Samsung is working on its own GPU design. It is not surprising that the company wants to develop its own graphics chip, having a unique CPU architecture. The new next-generation Exynos processor can be expected closer to the release of the Galaxy S10. Let's see what the company does with it.

By Android materials Authority

We have already discussed in detail what they are modern systems on-chip (mobile processors) from Qualcomm (line Snapdragon) and HiSilicon (which is owned by Huawei and produces not the most common, but technologically advanced chips Kirin), and now it has come Samsung time, known to the mass consumer thanks to Exynos systems.

Before the first Exynos, which Samsung began using in Galaxy S line smartphones in 2010, the company had chips since 2000. But there is no point in talking about them anymore, even though the S5L8900, for example, was used in Apple iPhone, and S5PC100 - in iPhone 3G and iPod Touch 3G. These devices have already been forgotten, so let’s move on to the current line, which for some time at the start was called Hummingbird.

The first chip of the modern series was the S5PC110, which was installed in Galaxy flagship S, which ultimately marked the beginning of one of the most popular smartphone lines in the world.

The Exynos 3, Exynos 4 and Exynos 5 lines mostly run on the ARMv7 architecture, while the more powerful 7, 8 and 9 run on ARMv8.

Please note that if the description of any of the systems contains few characteristics, this means that it borrows the missing ones from the previously released one and indicated in the list

Samsung released the new Exynos 7885 processor last year. The chipset looked promising, since in addition to Cortex A-53, A-73 cores are also responsible for performance. Let's take a closer look at this chip and compare it with the Qualcomm Snapdragon 450.

Main technical characteristics

The first thing to do is compare the main characteristics of the two processors. Will the new product from Samsung be able to leave the legendary “dragon” behind?

Characteristics	Qualcomm Snapdragon 450	Samsung Exynos 7885
Technical process	14 nm LPP	14nm FinFet
Number of Cores	8	8
Core architecture	Cortex-A53	6x Cortex-A53 and 2x Cortex-A73
Clock frequency	1.8 GHz	1.6 GHz, 2.2 GHz
Bit depth	64 bit	64 bit
Supported RAM	LPDDR3, 933 MHz, single channel, up to 4 GB	LPDDR4x, 1300 MHz, dual channel, up to 8 GB
Graphics chip	Adreno 506	Mali-G71 MP2
Communication standard support	X9 LTE ​​Cat 7, up to 300 Mbps	LTE Cat 12, up to 600 Mbps

As can be seen from technical characteristics, the Samsung chip looks a little more interesting than the Qualcomm processor. The guys at Samsung have clearly tried to make a great processor that can compete with the best chips.

Test results

However, only synthetic tests can give a more accurate answer to the question of who is stronger. They are the ones who are able to determine the best. The Qualcomm Snapdragon 450 was the first to test. And here are its results.

AnTuTu results for SD 450

As you can see from this chart, the results are not particularly impressive. Immediately after it, a new chip from Samsung was tested. And here the picture is completely different.

AnTuTu results for Exynos 7885

The Samsung chip left behind the Qualcomm processor. Now let's look at how things are going with graphics for both processors.

Graphic characteristics

It is these parameters that are responsible for whether smartphones based on these processors can handle modern games. And this is the picture that emerges.

And Exynos wins again. Devices on its platform will be able to run the latest games without any problems. But the “dragon”’s graphical characteristics are somehow not very good. Now let's look at camera support.

Camera support

It depends on the processor whether a dual photo module will be installed in a smartphone or whether it will be content with one. With cameras, things are the same for processors.

And again, the characteristics of the brainchild from Samsung are better. But for the “dragon” everything is not as good as we would like. However, let's move on to other characteristics.

Rest characteristics

This includes those parameters that cannot be separated into a separate block. These are wireless interfaces, navigation capabilities, and so on.

Characteristics	Qualcomm Snapdragon 450	Samsung Exynos 7885
Navigation Features	GPS, GLONASS, Beidou	GPS, GLONASS, Galileo
WiFi	a/b/g/n/ac	a/b/g/n/ac
Bluetooth	Bluetooth 4.1	Bluetooth 5.0
Support 2 SIM cards	Yes	Yes

But here everything is almost the same. At least somewhere the processors are on par. However, it's time to take stock.
