Rockchip RK3399 chip: VR delay can be less than 20ms

Recently, Rockchip announced the release of a new generation of its flagship chip RK3399. The chip features high performance and high expandability and can be used in popular VR products, tablet, and game/TV box products. Under the optimized algorithm, the delay of VR products based on RK3399 chip can be controlled under 20ms.

The RK3399 uses a dual Cortex-A72 large core and four Cortex-A53 small core architectures and has optimized a number of integers, floating points, and memory. The RK3399 is well balanced in terms of overall performance, power consumption, and core area. . Built-in image processor Mali-T860, overall performance than the previous generation increased by 45%.
