It is time for another comparison between mobile chips developed by Samsung. Today, the main role of this article play Exynos 7880, Exynos 8890 and Exynos 7420, which can be found in the popular Samsung smartphones Samsung Galaxy A5, Samsung Galaxy S7 and Samsung Galaxy S6 respectively. In the sections below we will share information about each of the chips, compare their benchmark results, and finally conclude with surface overheating tests.

Specs sheet Exynos 7880 Exynos 8890 Exynos 7420
Process 14nm FinFET 14nm FinFET 14nm FinFET
Cores 8 8 8
Frequency 1.9GHz up to 2.6 GHz up to 2.1 GHz
Architecture Cortex-A53 / 64-bit support Cortex-A53 + Exynos M1 / 64-bit support ARM big.LITTLE – Cortex-A53 & Cortex-A57 / 64-bit support
GPU Mali-T830 MP3 Mali-T880 MP12 Mali-T760 MP8

We start off with Exynos 7880 which is a 64-bit mobile processor developed by Samsung. It is available in the smartphone Samsung Galaxy А5 (2017). The mobile chip is manufactured through a 14nm technological process and features eight Cortex-A53 cores running at a frequency of 1.9 GHz. Along with it comes the Mali-T830 MP3 GPU. Moreover, the mobile processor boasts LTE Cat 7 connectivity with a download speed of up to 300Mbps, support for screens with resolution of up to 2560 х 1440 pixels, up to 21.7MP cameras and 4K video recording and playback at 30fps.

The second chip of this comparison is Exynos 8890 – the available mobile processor in Samsung Galaxy S7. This is a 64-bit chip manufactured through a “Second generation” 14nm FinFET technological process and features a total of eight cores – four Cortex-A53 cores running at 1.59GHz, as well as another four considerably more powerful Exynos M1 cores with a clock speed of up to 2.6GHz. The specs sheet is complemented by the support of LTE Cat 12/13 which means that download speeds reach 600Mbps (Cat 12), while the upload speeds – up to 150Mbps (Cat 13). Additionally, the mobile chip integrates the Mali-T880MP12 GPU.

The last chip we will take a look at is Exynos 7420. This is a 64-bit mobile processor that can be found in Samsung Galaxy S6. In addition, it is the first mobile processor which uses a 14-nm-FinFET-SoC LPE process, available in a smartphone. Exynos 7420 features four Cortex-A53 cores working at 1.5 GHz and four 2.1GHz Cortex-A57 cores. What’s more, it boasts LTE Cat 16 connectivity which will ensure download speeds of up to 450Mbps and upload speeds of up to 50Mbps. The available GPU here is Mali-T760MP8.

Benchmark results

We put to the test the computing, as well as graphics power of the three mobile processors with the help of several benchmarks the results of which you can see in the table below.

Benchmarks Exynos 7880 Exynos 8890 Exynos 7420
Geekbench 3 (Multi-Core) 4113 5391 4604
Vellamo 3 Metal 1370 3472 2678
GFXBench 2.7 T-Rex (offscreen) 34 83 59
GFXBench 3 Manhattan (offscreen) 15 40 26
GFXBench 3.1 Manhattan (offscreen) 9.1 29  –
3D Mark Ice Unlimited 13540 29162 21662

External temperatures

Apart from performance, we also tested the three chips for potential overheating issues after several hours of extended 3D gaming with the help of the Epic Citadel app. Immediately after this, we measured the temperatures in three sections of the smartphone’s back taking into account only the highest values. In all three cases, the temperature didn’t reach particularly worrying values but in Samsung Galaxy A5 the results were slightly lower compared to the other two flagships. The photos below display the registered temperatures in the three sections of each smartphone’s back.
