Qualcomm Snapdragon 8 Gen 2 for Galaxy vs Mediatek Helio G80
Qualcomm Snapdragon 8 Gen 2 for Galaxy
► remove from comparison
The Qualcomm Snapdragon 8 Gen 2 for Galaxy 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 3.36 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. Compared to the normal SD 8 Gen 2, the "for Galaxy" version offers a 160 MHz higher clocked prime core.
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.
Mediatek Helio G80
► remove from comparison
The Mediatek Helio G80 is a mainstream ARM SoC for smartphones (mainly Android based) that was introduced in 2020. It is manufactured in a 12 nm FinFET process and integrates 8 CPU cores. Two fast ARM Cortex-A75 cores with up to 2 GHz for performance tasks and six small ARM Cortex-A55 with up to 1.8 GHz for efficiency. All eight cores can be used together thanks to Heterogeneous Multi-Processing support. The integrated GPU is a ARM Mali-G52 MC2 (MP2) with two clusters at up to 950 MHz. The SoC also integrates the HyperEngine that handles a dynamic management of CPU, GPU and memory.
The SoC integrates furthermore a LTE radio with Cat-7 (download) / Cat-13 (upload) support, Wifi 5 (ac), Bluetooth 5.0, LPDDR4x 1800 MHz and eMMC 5.1 storage.
