The performance of Rockchip processor seems not so good... [Copy link]

 

I have a rk3568 board with 4 cores and 2G, and a single-core 2G main frequency. I installed G++11 on it and compiled our project directly. It takes about 2 minutes to compile a CPP with a single thread. If we increase the parallel compilation to 4 threads, it will be killed by Linux because of the resource consumption.

There is also an nxpimx6 board with 4 cores, 1G, and 800M per core. For the same compilation, it takes about half a minute to compile a CPP. If 4 parallel threads are added, it will not be killed by the system, and the compilation can be completed in about 3 hours.

The system kernel is the LTS version 4.19, and the file system is ubuntu22.04. Logically, rk3568 is superior in all aspects, but I didn't expect this result.

Is it a system optimization issue?

The rk3568 board is quite expensive. It is not cheap in Xianyu. On the contrary, I saw the cheap one in Xianyu.

I have the same feeling. For the same project, if I use Raspberry Pi and Rockchip, the Rockchip one will lag.

Although there is a certain gap between the two performances, the difference is not very large.

Today's systems cannot only look at the performance of the CPU main frequency core. NPU and GPU are both important, and system software is even more important. For example, if the domestic GPU software cannot keep up, it will greatly affect the performance. Even the level of PCB is critical.

Something is wrong, try flashing armbian on 3568

I haven't found the reason. Logically, compilation is pure CPU calculation, which shouldn't happen.

3568 seems to be the main model promoted by various industrial control boards.

Yes, I tried it with a Raspberry Pi, and it is also much faster than the 3568.

In terms of parameters, 3568 has great performance advantages

Logically speaking, the compiler is purely for calculations, so it shouldn't have such a significant impact. I don't understand it.

No problem, I'll try again later when I have time.

Yes, the parameters are similar to those of Raspberry Pi, but the actual running project is not as good as that of Raspberry Pi. Could it be that the system is not optimized?
