Qualcomm Snapdragon 8 Gen 2 for Galaxy vs Mediatek Dimensity 9400+
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 Dimensity 9400+
► remove from comparison
The Mediatek Dimensity 9400 Plus is a higher-end octa-core SoC for Android tablets and smartphones that was launched on April 10, 2025. As such, it is said to feature one powerful Cortex-X925 core (up to 3.73 GHz), three Cortex-X4 cores (up to 3.3 GHz) and four efficient Cortex-A720 cores (up to 2.4 GHz) along with the dedicated 890 NPU and Immortalis-G925 MC12 iGPU. The older Dimensity 9400 features the same key components, their lower clock speeds being the differentiating factor.
A chip for flagship 2025 and 2026 products, the Dimensity comes with powerful navigation and networking capabilities, including Wi-Fi 7 and Bluetooth 6 and other nice features such as support for three displays. It is built with TSMC's N3E process.
Performance
Given the clock speed improvement over the Dimensity 9400, its Geekbench multi-thread performance scores should be slightly higher than those of Apple's M1 and A18 Pro as well as Qualcomm's Snapdragon 8 Elite.
Long-term performance sustainability will depend greatly on how sound heat dissipation is in a particular tablet or smartphone.
