Qualcomm Snapdragon 7 Gen 1 vs Qualcomm Snapdragon 778G+ 5G

Qualcomm Snapdragon 7 Gen 1

The Qualcomm Snapdragon 7 Gen 1 (SM7450-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 two clusters. Four fast cores based on the ARM Cortex-A710 architecture with up to 2.4 GHz and four additional A510 based cores with up to 1.8 GHz in a power efficiency cluster.

According to ARM, the performance cores are 10 percent faster and 35 percent more efficient than the old  Cortex-A78 cores. The efficiency cores are supposed to be 35 percent more powerful and 20 percent more efficient than the old Cortex-A55 cores. The Snapdragon 7 Gen 1 supports up to 16 GB of LPDDR5-3200 RAM and UFS-3.1 flash memory. The SoC uses the integrated Adreno 644 for graphics card.

The Adreno graphics chip supports HDR10, HDR10+, Dolby Vision as well as HLG and relies on a hardware-accelerated H.265 and VP9 decoder. The 7th generation Qualcomm AI Engine offers features like Camera Deep Learning Face Detect (DLFD) and Video Super Resolution (VSR).

The Qualcomm Spectra Triple ISP (Image Signal Processor) enables three cameras to capture photos and videos simultaneously. The chip supports 200-megapixel cameras as well as 4K HDR video recording. 

The Snapdragon X62 5G modem integrated in the SoC allows simultaneous data transfers of 5G-mmWave as well as sub-6 GHz, enabling bandwidths of up to 4.4 GBit/s. Qualcomm's FastConnect 6700 is responsible for local communication, which supports Bluetooth 5.2 and Wi-Fi 6E, among other things. Speeds of up to 2.9 GBit/s are to be achieved via Wi-Fi 6E.

The SoC is manufactured in a modern 4 nm process at Samsung.

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).
