MT-3399 is a high-end development board based on Rockchip RK3399. MT-3399 is the first 64-bit development board with super high performance based on industrial control. MT-3399 is incorporated with six cores: four A53 cores and two A72 cores. Its dominant frequency is up to 2GHz.
RK3399 is rated monster level in terms of CPU and GPU. Incorporating two Cortex-A72 large cores and four Cortex-A53 small cores, the CPU has been greatly improved in terms of integers, floating decimals, and memory as well as overall performance, power consumption, and core area.
The GPU is incorporated with a new-generation high-end ARM image processor Mali-T860, which contains four cores, integrated with more bandwidth compression technologies, such as intelligent superposition, ASTC, and local pixel storage. The GPU also supports more graphic and computing interfaces and its overall performance is 45% greater than that of the last generation products.
Although these capabilities are called top capabilities of the chip solutions of the same kind, they are not the key features of RK3399. RK3399 is highlighted in the Type-C interface, embedded PCI-E interface, and two cameras that support gesture recognition, which help overturn the experience in using the game box products. RK3399 also has other new features, such as supporting LPDDR4 memory, ahead of the current mainstream products.
Built upon high configuration and the improvement in the overall performance as well as comprehensive layout, RK3399 is born to be an all-rounder. Apart from the panel computer, VR, TVBOX, and laptop, RK3399 is applied to a diversity of terminals in the industry and consumption fields, including intelligent household appliances, advertising machines/integrated machines, financial POS terminals, vehicle-mounted control terminals, thin clients, VOIP video conferencing, security/surveillance/police affairs and Internet of Things.
 Android System Configuration  	 CPU: RK3399 	 Clock speed:&nbsp; Four A53 (1.4GHz) cores + two A72 (2GHz) cores 	 Memory:&nbsp; 2GB for standard; 4GB be customized 	 Storage: 4GB/8GB/16GB eMMC optional, 16GB for the standard configuration 	 Power supply IC: Using RT808 and supporting dynamic frequency modulation
