Rockchip RK3368 chip compare with Amlogic S905 chip
As the chip updating, there are more and more android tv boxes in the market.Today we analyse two main stream chips for android tv box,Rockchip RK3368 and Amlogic S905.
Rockchip RK3368 used 28nm technology, 64-bit Big.Little architecture, octa-core based on ARM Cortex-A53, the basic frequency could be up to 1.5GHz. GPU used PowerVR SGX6110 GPU, that support OpenGL 3.1, OpenGL ES 1.1/2.0/3.0, OpenCL, DirectX9.3; and Support 4K 30fps H.264 decoding, 4K 10bits 60fps H.265 video decoding, and 1080P 60fps multiply video decoding. In encoding, it supports 1080P, H.264,VP8 format coding. RK3368 supports HDMI 4K@60Hz and 2048x1536 resolution output.
The parameters of the Rockchip RK3368 and Amlogic S905, we have known. What is the difference of their whole performance? In 2D and 3D drawing, RK3368 is better than S905. In multitasking and CPU floating point performance, s905 is more stronger. The results of the running test,the advangtage of RK3368 octa-core is not reflected. In GPU, there is big difference between RK3368 and S905. The FPS of RK3368 can up to 60, and S905 just up to 24.2.
Although RK3368 chip is Octa-core, its whole performance is not double of amlogic S905. In GPU performance, RK3368 is more better than S905. Anyway android TV Box based in RK3368 or S905, that is enough to deal with our daily life. Of course, this is just a rough comparison for two chips. In Specific practical application, ultimately cannot dispense with optimization of every android TV box manufacturer.
