Qualcomm Snapdragon 888 4G vs Qualcomm Snapdragon 778G 4G

Qualcomm Snapdragon 888 4G

The Qualcomm Snapdragon 888 4G Mobile Platform is a high-end SoC for smartphones that was introduced in mid 2021 and manufactured in 5 nm at Samsung. Compared to the earlier released Snapdragon 888 5G, the 4G variant only features a 4G LTE modem.

The chip integrates one “Prime Core” based on a ARM Cortex-X1 architecture clocked at up to 2.84 GHz. Three more performance cores are based on the A78 but clock up to 2.42 GHz. Furthermore, four energy saving cores are integrated that are based on the ARM Cortex-A55 architecture and clock at up to 1.8 GHz. In addition to the processor cores, the SoC integrates a WiFi 6e modem, a Hexagon 780 DSP (up to 26 TOPS of AI performance) and a Spectra 580 ISP. The integrated memory controller now supports faster LPDDR5 memory with up to 3,200 MHz. 

The performance of the processor cores should be around 15% better than the old Snapdragon 865+. The integrated Adreon 660 GPU should make a bigger jump by 35% (most likely compared to the SD 865).

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).
