Qualcomm Snapdragon 778G+ 5G vs MediaTek Dimensity 1080

Qualcomm Snapdragon 778G+ 5G

The Qualcomm Snapdragon 778G+ 5G (SDM778G Plus 5G 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 two clusters. A fast performance cluster with four cores based on the ARM Cortex-A78 architecture with up to 2.5 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. Compared to the older non-plus variant, the 778G+ offers 100 MHz higher clocked CPU cores.

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 778G+ is able to reach the performance of the old high end chip Kirin 990. 

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 642L offers a 40% higher performance compared to the old Adreno 620 in the predecessor. This is partly thanks to the fast memory controller with LPDDR5-3200 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 778G Plus is manufactured in the modern 6 nm process at TSMC (vs the 5LPE of the 780G).

MediaTek Dimensity 1080

The Mediatek Dimensity 1080 is a mid-range ARM SoC (system-on-a-chip) that can be used in both smartphones and tablets (mainly Android). The SoC integrates two ARM Cortex-A78 cores with up to 2.6 GHz for demanding tasks and six power-saving ARM Cortex-A55 cores with clock rates of up to 2 GHz.

The chip has an integrated sub-6 GHz 5G modem including dual-SIM support that can reach a maximum download speed of up to 2.77 Gbit/s. Wi-Fi 6 (802.11ax) is supported as well as Bluetooth 5.2.;

The memory controller copes with LPDDR4x or LPDDR5 working memory as well as UFS 3.1 mass storage. As an integrated graphics card, the SoC uses the ARM Mali-G68 MC4, which supports displays with 120 Hz as well as HDR10+ at a maximum resolution of 2,520 x 1,440 pixels.

The differences to the Dimensity 920 are minor, only the slightly higher maximum clock and a support for higher-resolution cameras can be found.

The MediaTek Dimensity 1080 is still manufactured in 6 nm.
