I wonder what the process node size of SW26010 is and if the chips were actually manufactured in China or if they were manufactured by TSMC/Taiwan. I wasn't aware that China had competitive fabrication plants for processors. If they don't and they built these at say 40 or 45nm then wouldn't this design performance be even more impressive?
