MediaTek Dimensity 8200-Ultra vs Qualcomm Snapdragon 778G 4G

MediaTek Dimensity 8200-Ultra

The MediaTek Dimensity 8200-Ultra is a upper mid-range ARM-based SoC (system-on-a-chip) that is manufactured using the modern 4 nm process. It was specially designed for use in Android smartphones and is in the upper class in terms of performance. It supports all current mobile communication standards, including 5G SA. 

The CPU works with a total of eight cores, which are divided into two clusters. In the first cluster, an ARM Cortex-A78 power core clocked at 3.1 GHz is joined by three further ARM Cortex-A78 power cores clocked at 3 GHz. In the second cluster, four ARM Cortex-A55 power cores operate at 2.0 GHz. LPDDR5 RAM can be used as RAM and UFS 3.1 is supported as internal memory. 

In terms of connectivity, dual 5G with a theoretical peak download speed of up to 4.7 GBit/s is available, as well as WiFi 6E and Bluetooth 5.3.

The Mediatek Dimensity 8200-Ultra is a variant of the otherwise identical Mediatek Dimensity 8200 that has been specially customised for Xiaomi and features improvements to the camera ISP. An Imagiq 785 image processor is responsible for processing the camera data. Video recordings are supported with up to 4K at 60 fps. The CPU part of the older Dimensity 8100 is very similar and offers the same CPU and GPU cores.

The integrated ARM Mali-G610 MC6 graphics unit can power displays with a resolution of up to 2,960 x 1,440 pixels (WQHD+) and a refresh rate of up to 120 Hz. With Full HD+, even up to 180 Hz is possible.

Qualcomm Snapdragon 778G 4G

The Qualcomm Snapdragon 778G 4G (SDM778G 4G 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 2.4 GHz and a power efficiency cluster with four small ARM Cortex-A55 cores at up to 1.8 GHz. Depending on the workload only single clusters or all cores can run at different clock speeds. In contrast to the Snapdragon 778 5G, the 778G 4G does not offer a 5G modem, but only supports 4G/LTE.

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 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 is manufactured in the modern 6 nm process at TSMC (vs the 5LPE of the 780G).
