Qualcomm Snapdragon 7 Gen 3 vs Qualcomm Snapdragon 8 Gen 2
Qualcomm Snapdragon 7 Gen 3
► remove from comparison
The Qualcomm Snapdragon 7 Gen 3 is a fast mid-range SoC with 8 cores for smartphones and tablets (mainly Android-based). It was launched in November 2023 and is intended as the successor to the Snapdragon 7s Gen 2.
Qualcomm combines an ARM Cortex-A715 performance core with clock speeds of up to 2.63 GHz with three Cortex-A715 cores at 2.4 GHz and four economical Cortex-A510 efficiency cores at 1.8 GHz. An Adreno 720 is used as the GPU, which supports Vulkan 1.3 and Snapdragon Elite Gaming.
Specifically, Qualcomm claims a 15 percent improvement in processor performance and a 20 percent improvement in efficiency compared to the Snapdragon 7s Gen 2.
The integrated ISP can process photos from a 200 MP camera and 4K HDR videos. Qualcomm promises a particularly effective night mode, in which 30 photos are taken almost simultaneously and combined into a brighter image.
Qualcomm has also installed a Snapdragon X63 5G modem that achieves a download speed of up to 5 Gbit/s. The phone supports Wi-Fi 6 and Bluetooth 5.3.
The SoC is manufactured in the modern 4nm process at TSMC and should have very good energy efficiency.
Qualcomm Snapdragon 8 Gen 2
► remove from comparison
The Qualcomm Snapdragon 8 Gen 2 Mobile Platform is a high-end SoC for smartphones that was introduced in late 2022 and manufactured in 4 nm at TSMC (N4P). It integrates four different CPU clusters. A fast and big prime core based on the ARM Cortex-X3 architecture and clocked at up to 3.2 GHz for 64 bit applications. Two more ARM Cortex-A715 based performance cores clocked at up to 2.8 GHz (also only for 64 bit apps). Two more Cortex-A710 performance cores at up to 2.8 GHz that can also be used for older apps and three efficiency cores (ARM Cortex-A510 with up to 2 GHz). All cores can use the shared 8 MB level 3 cache.
Thanks to the new architecture and high clock rates, the SD 8 Gen 2 is the fastest mobile CPU for Android based devices and is only topped by current Apple SoCs like the Apple A16 (see benchmarks below).
The chip also integrates a Hexagon accelerator for AI workloads (tensor, scalar and vector). Qualcomm states that its one of the first chips with INT4 support and up to 4.35x performance compared to the previous generation.
The 18-Bit-Spectra ISP is able to process photos with up to 200 MP and work with videos up to 8k30 (including 10-bit, HDR10+, HLG and Dolby Vision).
A big improvement of the Snapdragon 8 G2 is the integrated Adreno 740 GPU, that now supports Hardware Raytracing and tops even the iGPU in the Apple A16.
The integrated AI Engine can offer up to 4x faster AI performance thanks to the bigger Tensor engine. The 18-Bit-Spectra-ISP also saw some big improvements and is now called Snapdragon Sight.
The integrated Adreno 730 offers a 30% graphics boost compared to the previous Adreno 660.
The integrated Snapdragon X70 5G modem is also new as is the FastConnect 7800 modem with Wi-Fi 7 and Bluetooth 5.3 support.
