Comparison of basic parameters of Card Computer in China: E8 Card Computer and OK335xS-II Development Board

The card computer boom triggered by Raspberry Pi has also led to the development of small-sized card computers by embedded developers in China. The well-known embedded developer in China, tianyinao technology and Feiling embedded system, also developed card computers. Now, we will compare the basic parameters of the embedded E8 chip computer with the OK335xS-II Development Board of Feiling.

Comparison and analysis of the following basic parameters:

　　1. CPU comparison

E8 card chip computer is used in Samsung Cortex-A8 s5pv210 processor, OK335xS-II Development Board is used in Cortex-A8 Ti am3354 processor (industrial level ). Everyone is a Cortex-A8 series, basically equal magnitude. While the E8 chip computer processor clock speed is 1 GHz, and the OK335xS-II Development Board only 720-800mhz clock speed, obviously E8 chip computer CPU advantage.

　2. Memory comparison

The E8 chip computer uses 512 M DDR2 and the OK335xS-II uses 128 M ddr3. From the model, after all is the OK335xS-II is more advanced, but from the overall running speed or memory high E8 is more dominant.

　　3. Graphics processor

E8 card chip computer graphics processor is a processor comes with 3D/2D graphics Acceleration Engine (sgx540), The OK335xS-II uses powervr sgx530. According to the model analysis, the sgx540 is more advanced than the sgx530. In graphics processing, the E8 chip computer is overall higher than the OK335xS-II.

From the above three aspects of analysis, E8 Chip Computer in the basic parameters beyond the OK335xS-II. In terms of operation speed and graphics processing, E8 chip computers are also outstanding in low-end card computers in the market.
