Comparative Analysis of RK3399, RK3368, RK3288, i.MX6 Chip Parameters
RK3368 is the world’s only octa-core 64-bit OTT BOX chip in 2015. It is also a new generation of TV box solutions, and may become the standard configuration of a new generation of flagship OTT BOX products. It adopts eight-core 64-bit ARM Coretex-A53 architecture, 28nm process design, running at 1.5GHz; GPU is PowerVR G6110, supports OPENGL ES 3.1; RK3368 has super video capability, supports 4K×2K video, H.264/H .265 hard decoding and HDMI 2.0@60Hz output.
The RK3288 processor adopts the quad-core ARM Cortex-A17 architecture. Its biggest feature is that it adopts a completely out-of-order execution architecture like the Cortex-A15, and its performance improvement has an immediate effect. The GPU adopts Mali T76X series GPU. The biggest feature of Mali T764 core is the third-generation Midgard architecture. Rockchip RK3288 also supports 4Kx2K, as well as a chip for hard decoding H.265 video, bringing users clear visual enjoyment as a more efficient HD compression format.
RK3399 is a low-power, high-performance application processor chip launched by Rockchip. The chip is based on the Big.Little architecture, that is, a dual-core Cortex-A72 and quad-core Cortex-A53 combined architecture with an independent NEON co-processor , mainly used in computers, personal Internet mobile devices, VR, advertising machines and other intelligent terminal equipment. RK3399 has built-in multiple high-performance hardware processing engines, which can support multi-format video decoding, such as: 4K*2K@60fps H.264/H.265/VP9, also supports 1080P@30fps H.264/MVC/VP8 and High-quality JPEG codec and image pre- and post-processor.
