Samsung Exynos 9820 vs Qualcomm Snapdragon 780G 5G vs Samsung Exynos 9810

Samsung Exynos 9820

The Samsung Exynos 9 9820 is a mobile SoC for smartphones and tablets. It was announced late 2018 and was first integrated in the Samsung Galaxy S10 smartphones early 2019. The SoC integrates three clusters of processor cores with different architectures. Two big Samsung custom M4 cores clock up to 2.7 GHz and deliver peak performance. Two additional ARM Cortex-A75 are also for performance tasks and clock at up to 2.3 GHz. Finally, four small and power efficient ARM-Cortex A55 cores clock at up to 1.9 GHz are in the third cluster. The different clusters can run simultaneously thanks to DinamIQ.

The integrated LTE modem supports LTE-Advanced Pro Cat.20 (8CA 2 Gbps download, 3CA 316 Mbps upload). The integrated graphics card is a ARM Mali G76MP12 with 12 cores.

The performance of the CPU part is positioned in the high end segment for smartphone processors. The single core performance is, thanks to the big custom cores, a strong suit of the CPU and reaches the levels of Apples mobile SoCs. The direct competitor Snapdragon 855 can be left behind in single-core benchmarks like Geekbench and operates on par in multi-core benchmarks. The predecessor Exynos 9810 can be bested by around 17% in our first benchmarks with the Galaxy S10 Plus.

The SoC is produced at Samsung in the new 8nm LPP process that should also help with some of the performance gains.

Qualcomm Snapdragon 780G 5G

The Qualcomm Snapdragon 780G 5G (SM7350-AB Mobile Platform) is a fast mid-range ARM-based SoC largely found on Android tablets and smartphones. It integrates eight cores (octa-core) divided into three clusters. A fast prime core for single thread performance based on the ARM Cortex-A78 architecture with up to 2.4 GHz. Three additional A78 based performance cores with up to 2.2 GHz and a power efficiency cluster with four small ARM Cortex-A55 cores at up to 1.9 GHz. Depending on the workload only single clusters or all cores can run at different clock speeds.

Thanks to the new Cortex-A78 cores, the CPU performance increases by up to 40% compared to the old Snapdragon 768G according to Qualcomm. In our benchmarks, the 780G is able to reach the performance of the old high end chip Kirin 990. The multi-thread performance is similar to the old Snapdragon 865+ in the Galaxy Z Fold2, but using a single core, the 780G is trailing behind.

The integrated X53 5G modem supports up to 3.3 Gbps with sub 6Ghz. The FastConnect 6900 Wi-Fi modem supports the current Wi-Fi 6e standard with 6GHz.

The integrated Qualcomm Adreno 642 offers a 50% higher performance compared to the old Adreno 620 in the predecessor. This is partly thanks to the fast memory controller with LPDDR4X-4200 support.

The integrated 6th gen AI engine called Hexagon 770 offers a 2x improvement and up to 12 TOPS of performance. The Spectra 570 ISP (image signal processor) supports up to three cameras. The satellite system supports all major standards like Beidou, Galileo, GLONASS and GPS.

The G specifies an optimized SoC for gaming and e.g. Qualcomm offers updates for the graphics driver.

The Snapdragon 780G is manufactured in the modern 5 nm process at Samsung (5LPE with EUV).

Samsung Exynos 9810

The Samsung Exynos 9 9810 is a mobile SoC for smartphones and tablets. It was announced early 2018 and should be integrated in the upcoming Samsung Galaxy S9 series (at least partly). It integrates eight CPU cores (octa core) in two clusters. The performance cluster integrates four Samsung M3 at 2.9 GHz and the power efficiency cluster four small ARM Cortex-A55 cores at 1.9 GHz. The Samsung M3 cores are based on Samsungs own design and now offer a wider pipeline, improved cache memory and bigger caches. This leads to a twice as fast single-core performance and a 40 percent improved multi-core performance according to Samsung (most likely compared to the previous Exynos 8898).

The integrated LTE modem also got a siginifcant upgrade and now supports Cat.18/13 LTE for up to 1.2 Gbps download and 200 Mbps upload. This is achieved with 6x20 MHz CA, 256-QAM in download and 2x20 MHz in upload.

As a GPU, Samsung integrates a ARM Mali G72MP18 (only 18 clusters, compared to the 20 clusters of the predecessor G71MP20). Most likely Samsung increases performance due to a higher core clock of the graphics card.

The memory controller looks similar to the 8898 and supports LPDDR4x 1800 MHz. The video engine now also supports 10 bit videos (as before 4k120 H.265/HEVC, H.264 and VP9 de- and encoding). 

The SoC is produced at Samsung in the new 10nm LPP process (the Exynos 8898 still used the 10nm LPE process) that should also help with some of the performance gains.
