Qualcomm Snapdragon 865 vs Qualcomm Snapdragon 778G+ 5G
Qualcomm Snapdragon 865
► remove from comparison
The Qualcomm Snapdragon 865 Mobile Platform is a high-end smartphone and tablet SoC that Qualcomm announced in December 2019. The SoC integrates a fast ‘Prime Core’ that clocks up to 2.84 GHz and three further fast ARM Cortex-A77 performance cores, which can reach up to 2.42 GHz. These are complemented by four power-saving ARM Cortex-A55 cores that clock up to a maximum of 1.8 GHz. The difference to the older Snapdragon 855 is the switch from Cortex-A76 to the faster Cortex-A77 architecture. The clock speeds stay the same.
Therefore, the Snapdragon 865 takes the top spot in mobile processors for Android based systems. In some multi-core workloads, the SD865 can even perform on par with the Apple A13 SoC. Single thread, however is still a strong suit of the Apple SoCs.
Compared to the previous generations, the Snapdragon 865 does not integrate an LTE modem anymore, but has to be paired with the new X55 5G modem, that also supports LTE Cat 24/22. The Wi-Fi module however is still integrated and called FastConnect 6800 with support for Wi-Fi 6 (802.11ax) and 8x8 MU-MIMU and 60 GHz 802.11ay with up to 10 Gbps. Bluetooth 5.1 is also supported including aptX Adaptive.
The integrated GPU is now called Adreno 650 and should offer 20% more performance than the Adreno 640 in the Snapdragon 855.
The on board Hexagon 698 DSP now offers an improved KI performance of up to 15 TOPS (up from 7 TOPS in the 855) and still uses a combination of CPU, GPU, HVX and Tensor cores. The Spectra 480 ISP is now also significantly faster. The integrated Computer Vision Engine (CV-ISP) now supports Dolby Vision, 8K videos and 200 megapixel photos.
The built-in memory controller now supports LPDDR5 with up to 2,750 MHz and LPDDR4X with 2,133 MHz.
The Snapdragon 865 is manufactured at TSMC in the new improved 7nm process (N7P, DUV-based). The process offers a 7% higher performance or 10% less power consumption compared to the old N7 process.
Qualcomm Snapdragon 778G+ 5G
► remove from comparison
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).
