Qualcomm Snapdragon 4 Gen 2 vs Unisoc T8100 (T760)
Qualcomm Snapdragon 4 Gen 2
► remove from comparison
The Snapdragon 4 Gen 2 (SM4450) is an entry-level eight-core SoC that is the successor to the Snapdragon 4 Gen 1. It integrates a total of 8 cores divided into two clusters.
The SoC continues to rely on the same core constellation as its predecessor, but with higher clock rates. In addition to two fast Cortex-A78 cores that clock at up to 2.2 GHz, the Snapdragon 4 Gen 2 has six energy-saving Cortex-A55 cores that operate at a maximum of 2 GHz.
The performance is on par with the similar but older Snapdragon 695 5G, the Mediatek MT8188J and the Mediatek Dimensity 7020. The Snapdragon 6 Gen 1 of the next faster tier, is about 29% faster in our benchmarks (Vivo V40 Se vs Honor Pad 9).
The Adreno 613 graphics card is different to the predecessor and as the name implies - and our benchmarks show, it is slower then the Adreno 619 in the SD4 Gen 1. It supports important graphics APIs such as OpenGL ES 3.2, OpenCL 2.0 and Vulkan 1.1. It is also capable of hardware-accelerated decoding of H.265 and VP9 data.
The Snapdragon 4 Gen 2 can rely on the Qualcomm X61 5G modem, which supports maximum download rates of up to 2.5 GBit/s (upload: max. 900 MBit/s). Only Wi-Fi 5 is supported for WLANs and Bluetooth 5.1 is also no longer up to date. The dual ISP works with up to 12 bit and operates with a maximum resolution of 108 MPix. Quick Charge 4 is integrated as fast charging technology.
The Snapdragon 4 Gen 2 is manufactured with a structure width of 4 nm at Samsung (compared to the 6nm TSMC Process of the SD 4 Gen 1).
Unisoc T8100 (T760)
► remove from comparison
The Unisoc T8100 (previously known as the Unisoc T760) is a mid range SoC for Android based smartphones and tablets. It integrates an octa-core CPU with two clusters. Four fast ARM Cortex-A76 cores clocked at up to 2 GHz and four small ARM-Cortex-A55 cores at again up to 2 GHz for efficiency. The faster T770 SoC offers higher clocked A76 cores in comparison (up to 2.5 GHz for a single core).
One fast ARM Cortex-A76 clocked at up to 2.5 GHz, three more A76 performance cores clocked at up to 2.2 GHz and a power efficiency cluster of four ARM-Cortex-A55 cores with up to 2 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 780 MHz.
The chip is manufactured on the modern 6nm process.
