Re: improving yeeloong: some suggestions
Thank you very much for feedback and suggestions.
The video and wifi issues are really bad for us. We will try to improve
the drivers and choose better chips for next model.
For the cpu, they are sold as 900MHz/1.3v in their specifications, due to
various considerations(no exactly 900M due to the multiplier;the memory
side might be harder to get stable; the power), we use it at 800M/1.2v. We
are actively working on improving the cpu performance anyway.
Next generation(Loongson2G) is expected a higher frequency with
Hypertransport interface, which can interface to Nvidia/AMD HT
southbridges, hopefully the video/cpu performance will have a big
difference.
