Please give a comprehensive analysis of the advantages and disadvantages of i.MX8QuadMAX and RK3399PRO [Copy link]

RT!
I feel that the configurations of these two socs are very similar, both are 2*A72 + 4*A53.
Comparing them, what are their respective advantages and disadvantages?
What are their respective areas of expertise?
Please give me some advice

It is i.mx8quadmax and rockchip rx3399pro

The kernel is the same as the peripherals. Almost all of imx's peripherals are tested in Freescale's industrial environment. The stability of imx peripherals is almost unnecessary, while some cheap chips often cut a lot of test links to save costs. Some peripherals are very similar to those on Freescale's MCUs, and some peripherals are also available on other kernels such as Freescale's own powerpc or dsp. In addition, the process, I don't know what process they use, but from the fact that the main frequency of nxp's M7 core runs to 1G, compared with ST's H7, it can be seen that it is difficult to produce. Then look at the openness. As far as I know, the chip manual of imx can be fully downloaded publicly, and Rockchip will not talk about it. Finally, look at the development chain. The entire software ecosystem of imx has the strong support of nxp. For example, they can modify the compiler and embedded C library (or buy others' free ones for people to use) to optimize the performance, efficiency and space of general gcc and newlibc, or optimize the code generation for their own devices, or have professional systems that have passed relevant certifications, of course, there are free and paid ones for people to use. Admittedly, 80% of applications do not require very high performance indicators, so cost-effectiveness is king, isn't it?

Many e-book readers use i.mx 6 / 8

I don't know what soc is used in the TV industry.

There are many TV mstar solutions, you can refer to them
