Creative imagination supported by professional imaging capabilities

T820 features a quad-core ISP architecture combined with UNISOC's sixth-generation Vivimagic image engine, boasting a 100 Megapixel camera and full-pipeline 4K high-definition video recording. Supported by UNISOC's own AI algorithms, it can provide AI noise reduction, AI-HDR, AI-Bokeh, AI FaceID, AI Face Detection services, and a variety of other AI imaging functions.

T820's ISP processing performance can support UHD shooting up to 1.6 billion pixels per second, giving users the flexibility to mix and match different resolutions such as 108MP, 64MP, 50MP, and 48MP. While improving overall performance, the chip also seamlessly controls power consumption and temperature rise.

The most difficult night-time photography involves low light and shooting by starlight. Featuring 14bit RAW processing, a new "heterogeneous image processing engine" architecture, and equipped with dedicated night-time XDR multi-frame and multi-exposure shooting capabilities, T820 is able to restore greater details and provide higher-quality night scene effects.

Outstanding AI capabilities for full-scenario artificial intelligence

T820 features a new-generation, highly efficient NPU+VDSP architecture to vertically optimize computing power, with NPU computing power reaching 8 TOPS. This enables a 67% increase compared to the previous generation, optimizing bandwidth bottlenecks, releasing an extra surge of computing power, and leading the industry in energy efficiency and area efficiency.

Thanks to its brand new AI computing platform, T820 provides a full-stack AI solution that integrates software, hardware, and artificial intelligence algorithms. This technology supports low-bit quantization of model weights values and activations, including 4bit to 8bit, 10bit, 12bit, and 16bit precisions. Featuring access to mainstream industry AI training frameworks and advanced compression technology, T820 is capable of deploying “large models” at the back end.
