Unisoc T9100 (T820) vs Qualcomm Snapdragon 8 Gen 2 vs Qualcomm Snapdragon 8 Gen 2 for Galaxy
Unisoc T9100 (T820)
► remove from comparison
The Unisoc T9100 (formely Unisoc T820) is a mid range SoC for Android based smartphones and tablets. It integrates an octa-core CPU with three clusters. One fast ARM Cortex-A76 clocked at up to 2.7 GHz, three more A76 performance cores clocked at up to 2.3 GHz and a power efficiency cluster of four ARM-Cortex-A55 cores with up to 2.1 GHz. The integrated memory controller supports LPDDR4/4X with up to 2133 MHz (2x 16 Bit). The integrated ISP supports two main cameras and two subsidiary cameras (up to 108 MPix). The integrated graphics card is an ARM Mali-G57 MC4 (4 cores) at up to 850 MHz. Unisoc also specifies that the T9100 offers hardware AI acceleration with up to 8.0 TOPS peak performance of the NPU.
The chip is manufactured on the modern 6nm EUV process.
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.
Qualcomm Snapdragon 8 Gen 2 for Galaxy
► remove from comparisonThe 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.
