Amlogic A311D/A311D2 Octa-core

About

Amlogic A311D2 is an upgraded version of A311D, which has improved performance and supports richer video input and output interfaces, NPU becomes an option. Compared with the A311D, the new version of the A311D2 is more suitable for commercial display or smart large screen product applications. A311D2 has 4x Cortex A73 at 2.2Ghz, 4x Cortex-A53 at 2.0GHz, four Cortex-A53 cores, and a more powerful Mali-G52 MP8 (8EE) GPU, which supports up to 16GB LPDDR4/X memory, providing performance guarantee for product applications. A311D2 supports eDP and LVDS video interfaces, supports 2x V-by-One outputs, and 3x HDMI 2.1 up to 4Kp60. A311D2 supports 8K@24fps AV1 video decoding, integrates a 16MP ISP, and supports 4K video encoding. A311D2 can support 4K UI rendering, which is currently only available for flagship products, and can provide better visual effects for high-resolution apps.
