Exynos 2100 chipset comparison with Snapdragon 888: Which version of Galaxy S21 is better?

Comparing the Exynos 2100 chipset with the Snapdragon 888, we challenge two different versions of the Galaxy S21 Ultra in terms of performance and heat output.


For years, Samsung has been shipping a special version of its flagship to the US market, and this year is no exception. Samsung has come up with  two different chipsets for its new flagship, the Galaxy S21 – one from Korea and one from Qualcomm. The Exynos 2100 for the European and Asian markets and the Snapdragon 888 for the US market will be the beating heart of the S21, and since the two chipsets are designed and manufactured by two different companies, speculation is rife about their performance differences.

Many tests have been done on two different versions of the S21, and for example in terms of benchmark or battery life, the Exynos version of this phone has performed close to the Snapdragon version. But now we come to the chipsets themselves, and by comparing the Exynos 2100 with the Snapdragon 888, we want to take a closer look at the differences between the different versions of the S21.

Before starting the screen resolution settings, we set both phones to QHD and the screen refresh rate is set to automatic.

Heat generation test

To measure the amount of heat produced by the chipset, we must follow some tips. As we know, with increasing CPU temperature, operating frequency and performance are also affected and move away from the ideal state. We want to activate the processors and force them to run at maximum power for a few minutes. In this way, the speed and power of the chipset will be comparable.

To do this, you have to give the phone a long and heavy task to activate all the processor cores, because the main heat is generated by these cores and other parts, such as the GPU, play a much smaller role in heating the body. Since even the heaviest Android games can not activate all the processor cores, so we have to put the phones in abnormal condition and work with special programs from all cores. By doing this, we can evaluate the performance of different versions of the Galaxy S21 in the worst conditions.

To make the results more tangible, let’s add the numbers we see in the screenshots above. The Snapdragon 888 version of the Galaxy S21 Ultra scored 250353, 210296 and 192271 in maximum performance, average performance and minimum performance, respectively, and was able to maintain 77% of its ideal performance in the one hour we tested it.

Heat generation test Maximum At least Average Maintained performance after one hour
Galaxy S21 Ultra (Snapdragon 888) 250353 210296 192271 77%
Galaxy S21 Ultra (Exynos 2100) 244339 195471 137807 56 percent

On the other hand, the Exynos 2100 version of the Galaxy S21 Ultra scores 244339, 195471 and 137807, respectively, and offers only 56% of its ideal performance. This is a fundamental difference between the Exynos 2100 chipset and the Snapdragon 888.

The Snapdragon chipset on the Galaxy S21 Ultra can last longer under the artificial pressure we created, and outperformed the Exynos.

If we look at the chart below, we may be wrong at first. The red line belongs to the version of Samsung’s flagship Snapdragon and the blue line belongs to the Exynos version, and as can be seen, the Samsung chip has experienced a significant and deep decline compared to the American version. In fact, the Exynos version has gradually declined in performance and eventually stabilized. In contrast, the Snapdragon 888 slowed slightly and improved again in the final moments of testing. Here we prefer the performance of the Exynos 2100, because the lower the performance fluctuation of the processor, the less lag.

Of course, we can look at this issue from another perspective. Compared to the Exynos 2100 chipset and the Snapdragon 888, the peak Korean product recorded lower performance and ended up with lower performance. Eventually a large gap was created and the CPU performance was greatly reduced which led to more logs.

All in all, the Exynos chipset is struggling with problems that make Snapdragon not work properly and mentally, as can be seen from the heat generation test of these two phones. The low scores of this chip also confirm our claim, and although the two chips are currently under artificial pressure, it is not unlikely that the device will suffer the same pressure in the coming years while playing heavy games.

Entoto successive tests

Comparing the Exynos 2100 chipset with the Snapdragon 888, we decided to complicate our test a bit and went to the AnTuTu program, we performed 5 consecutive GPU-centric tests with this program and the results can be seen in the chart below. In this way, the long-term performance of the chipsets under high pressure and activity is determined.

Here again, the Snapdragon version scores better and has less power over time than the Exynos. This test was performed to test the theory of “heat generation by the processor” and, as we expected, the performance drop was smaller than the processor tests.

The performance lines of the different versions of the Galaxy S21 Ultra this time are closer to the CPU test, and there is no significant difference between them. In the 3DMark Vulkan test, the Exynos Mali-G78 MP14 GPU is not much weaker than the Snapdragon Adreno 660, and the advantages are minor.

Since the Exynos outperformed the Snapdragon in heat distribution and temperature control, we expected the same from the GPU, and the Mali GPU trend was predictable.

We can not be satisfied with the results of this test to announce the top phone because the results are very close to each other and although these results have been achieved under maximum pressure, they are still among the best in 2021.

Concluding remarks

Who is the winner after all? Determining the top winner and chipset for the Galaxy S21 Ultra is an academic affair, full of curiosity and enthusiasm, and as the test results show, the two versions are very similar in practice. There is no doubt that compared to the Exynos 2100 compared to the Exynos 990 released last year, we have seen significant improvements in the new version, and Samsung has been able to produce a powerful and up-to-date chipset; Although the Exynos 990 chip itself is known as a flagship and powerful chipset.

But the winner of the battle between Exynos 2100 and Snapdragon 888 will be Qualcomm, which has more points. If you want to spend a lot of time on mobile gaming or you like to extract decimal numbers in your spare time, the 2021 version of Samsung’s flagship Snapdragon will be for you. Of course, the functional difference between the two versions is not significant, and you can easily trust the S21 version that is offered in the country without worrying about running Android applications.
