Loongson development background: Loongson's CPU adopts MIPS architecture/instruction set, which is itself a relatively small architecture. MIPS has long lost its original glory, and its parent companies have been acquired by Imagination. Moreover, the precarious imagination means that the entire MIPS orthodox lineage or industry standards have been hit hard. In this context, Godson can only rely on its own development. It can be said that it can't find any reference, and many technologies can only be explored by itself. This is not so much an opportunity as a challenge for Loongson, which is already short of production capacity and funds.
Performance: Loongson's latest processor 3A/B3000 is still at 28nm (I remember it was 28 nm), which leads to three problems, one is that the frequency can't go up, the other is that the performance can't go up, and there is heat and power consumption. Looking at the performance alone, I have seen some evaluations, which are slightly better than ARM a7X and surpass Intel's atom series processors on the desktop, with a power of 30w. Compared with the current Ruilong and Intel Core series, there is still a big gap. I guess it can compete with i3 2xxx in some aspects, but it still lags behind i3 2xxx on the whole. On the one hand, stability has not been tested by the market. On the other hand, there is still a big gap between application optimization and mainstream processors. On the other hand, although some performance indicators of Loongson have caught up, it is still affected by the short board effect.
Godson is not as bad as some people think, nor as good as some people boast. Take the lead in domestic general-purpose processors (don't compare DSP with Loongson). Its performance is no longer limited to meet the current common use, such as office video, but it is still stretched for those high-computing fields. In short, if you play large games and often compress large files, you can bypass the scene that really squeezes CPU performance. If you just brush the web page and watch the video, Godson is completely satisfied. It's a mess, but I hope it helps you.
