GalaxyS9 Plus: Snapdragon 835 modification vs Exynos 9810

Starting with the Galaxy S7, Samsung began releasing devices, some of which run on the Qualcomm chipset, others on Exynos, which is a home-made Korean product. Qualcomm can most often be found in the USA and China, the Eynos version is more typical for the rest of the world's markets.

Usually there is no radical and significant difference between these two smartphone options. Except that the Exynos 8895 for the Galaxy S8+ showed slightly better battery life than the Galaxy S8+ on the Snapdragon 835.

Both processors are manufactured at Samsung factories using a 10nm process technology. Exynos uses a home-grown 3rd generation M3 core paired with a Mali-G72 MP18 accelerator. For Snapdragon 845, Kryo 385 is paired with an Adreno 630 accelerator.

Both chipsets show improved performance compared to last year's. The same Exynos 8895 from the Galaxy S8+ is about 2 times weaker in the single-core test and drops by 40% in the multi-core test. This is not least due to the increase in frequency from 2.3 GHz to 2.9 GHz.

The difference in graphics performance is minimal compared to last year. The current Mali-G72 has 18 cores, last year's Mali-G71 had 20, but the frequency this time is 572 MHz, which is 30 MHz more than last year's model. As a result, we get results at approximately the same level.

And in the case of Qualcomm, a 30% increase in video processing is announced for the current Sdreno 630 versus last year’s Adreno 540.

Samsung Exynos 9810 Octa Core: mobile processor for Galaxy S9

The first details of the Samsung Exynos 9810 Octa Core have appeared online. This mobile processor is intended for the future flagship smartphone Galaxy S9/S9 Plus, and also, quite possibly, the Galaxy Note 10. Both new products should be released next year 2022.

In general, it is correct to talk not about a processor, but about a “single-chip system” (System-on-a-Chip - SoC) or chipset, since modern mobile chips include not only the CPU itself, but also a graphics accelerator, modem, WiFi adapter , image processing coprocessor and many other components.

Exynos 9810 Specifications

So, it is expected that Samsung Exynos 9810 will be manufactured using either a 7 nm or 8 nm process technology at the production facilities of the South Korean giant itself. This will allow you to simultaneously increase the number of transistors on the chip (and, therefore, increase performance) and reduce power consumption and heating.

The processor itself will include four high-performance custom Exynos M3 cores and four “quiet” ARM Cortex-A53 cores. According to another version, Samsung plans to use more advanced ARM Cortex-A55 cores instead of the latest ones. The maximum possible amount of RAM will be increased to 16 Gb.

Next question: integrated GPU Exynos 9810. At the moment there is no exact data about it. Rumors attribute the new product to the Mali-G72 GPU graphics accelerator from ARM, which was announced in May of this year. It supports configurations of up to 32 cores and operates at frequencies up to 850 MHz.

ARM Mali-G72 GPU architecture

However, Samsung may choose other graphics for the Exynos 9810, for example from PowerVR (as in Apple chipsets for the iPhone), or even develop its own solution. The latter is not so incredible given the vast experience in developing our own chips.

The built-in modem of the new Exynos should receive support for 4G LTE Category 18 networks. This, in turn, promises data download speeds of up to 1.2 Gbps, which is comparable to 5G. But the transfer speed will most likely remain at the Category 13 level (150 Mbit/s).

Most likely, Samsung will integrate a new image processing co-processor into the Exynos 9810 with improved support for dual cameras, including options such as zoom and depth sensing. The maximum resolution is supposedly 21 Mp + 21 Mp.

Other expected features: new generation of wireless charging, Bluetooth v5.0, UFS 2.1 fast flash memory controller, support for two SIM cards, VoLTE, NFC, GPS navigation, Glonass, Beidou and Galileo, tri-band WiFi (2.4 GHz + 5.0 GHz + 60 GHz - 802.11ad).

Comparison with competitors

Exynos 9810 vs Snapdragon 845

Traditionally, Samsung releases its top-end smartphones simultaneously on its own chipsets and solutions from Qualcomm. This allows you to compare their performance most accurately, since the rest of the hardware is practically the same.

Traditionally, Samsung processors are stronger in multi-core mode due to better internal optimization, while Qualcomm is better in single-core mode. Most likely, in the case of Qualcomm Snapdragon 845 the situation will be similar.

Exynos 9810 vs Apple A11

If we compare the top mobile processors of Exynos and Apple, the latter have been showing much higher speed of calculations on a single core than the former for several years now (almost one and a half times).

In addition, this year in Cupertino they decided to increase the number of cores intended for the iPhone 8 Apple A11 to 6, so Samsung engineers have to work hard in order to oppose something serious to their main competitor.

Exynos 9820 vs Exynos 9810: what has changed

Today Samsung introduced its first processor with an 8nm process technology, Exynos 9820. It is the successor to the top-end Exynos 9810, presented at the very beginning of this year, and will probably be installed in the Russian-European version of the Galaxy S10 (February-March 2019) and Galaxy Note 10 (August-September 2019). Comparative characteristics of both processors are presented in the table below:

As you can see, the main changes affected:

• technical process - it changed from 10 nm to 8 nm
• structure and composition of the CPU - 2-cluster (4+4) was replaced by 3-cluster (2+2+4), older cores were updated,
• structure and composition of the GPU - the cores were changed to more modern and productive ones (with a double increase in the number of lanes), their number was reduced by 1/3
• NPU - appeared for the first time in a Samsung processor.

Samsung's press release names the following qualitative changes:

• the new custom core (M4) is about 20% faster than its predecessor (M3) in single-core performance (probably at the same level of power consumption)
• Energy efficiency (performance per watt) of M4 compared to M3 improved by 40%
• multi-core performance of Exynos 9820 compared to Exynos 9810 increased by about 15%
• Graphics performance of Exynos 9820 compared to Exynos 9810 increased by 40%
• Energy efficiency of Exynos 9820 compared to Exynos 9810 has improved by 35%
• thanks to the built-in NPU, the speed of machine learning has increased 7 times
• 8K video recording is supported.

Let me remind you that, according to leaks that appeared in the summer, the speed of the Exynos 9820 in the single-core Geeknench test increased by 21% (against Samsung’s stated 20%), and in the multi-core test by 40% (versus 15%).

As Gadgets News already reported, the Exynos 9810 turned out to be a rather controversial processor. On the one hand, in the single-core Geekbench test it was almost twice as good as its predecessor, Exynos 8895, and 37% faster than its main rival, Snapdragon 845. But in the multi-core test, the progress was much less significant - 35% more productive than Exynos 8895 and about the same as Snapdragon 845.

In the GFXBench Manhattan 3.1 graphics benchmark, the performance per watt of power consumption of the Exynos 9810 doubled compared to the Exynos 9810 and was equal to the Snapdragon 845. But thanks to higher power consumption (in this benchmark - approximately 5 W vs 4 W), the peak performance of the top Qualcomm processor was much higher. Both processors show very strong throttling - both had stable (stabilized) performance of 58% (Apple A11 - 54%).

The bottom line is that the Snapdragon 845, its predecessor Snapdragon 835 and A11 Bionic had approximately the same stable performance - about 35 fps in GFXBench Manhattan 3.1 (off-screen). In turn, the Exynos 9810 scored 27 fps in this test - slightly more than its predecessor Exynos 8895 (24 fps).

However, it should be borne in mind that the Qualcomm processors above were tested on the American-Chinese version of the Galaxy S9, and soon after its release - in March 2022. On another smartphone (OnePlus 6), the Snapdragon 845 showed a much better result - 51 fps sustained performance . But for the Galaxy S9 with the Exynos 9810 processor, by October 2022 it even worsened slightly - 25 fps. The favorite in this test among smartphones today is the Apple A12 (iPhone XS) - 61 fps. The following table shows the latest results in GFXBench Manhattan 3.1 (off-screen):

1 data on power consumption during stable operation of the processor is available only for the iPhone XS - 3.8 W.

Of course, it is possible that the reason for such significant throttling of both processors in the Galaxy S9 is its high (compared to the same OnePlus 6) display resolution. But judging by the game performance graphs, they run at a lower resolution on the Galaxy S9 (according to NotebookCheck.net):

OnePlus 6

Galaxy S9

As you can see, on both smartphones both games are designed for 60 fps, although of course the Galaxy S9 throttles much more in one of them (Arena of Valor).

This is the approximate situation for today, on the day of the announcement of the Samsung processor for its top smartphones in 2022. Taking into account the 40% increase, the sustained performance of the Exynos 9820 in Manhattan 3.1 (off-screen) can reach 38 fps - but even in this case it will be significantly behind the Snapdragon 845, not to mention the A12 Bionic. In addition, in the coming months the presentation of a new and, of course, more powerful Qualcomm processor is expected, which will be installed in almost all top smartphones next year.
