Next-gen Chinese GPU touts RTX 2080-level performance — Loongson claims 9A2000 is up to 10x faster than the 9A1000

Are there drivers for Windows with a control panel? Is the documentation open for it to get into mesa, or a binary like Nvidia's drivers?

And? I can claim to have a GPU as powerful as Nvidia, I need to prove and show the price, power usage and temp to see if it's really equivalent

I wouldn't install or touch anything from the CCP.
