You don't do your first experimental test chips on 4nm. That's where you get to when you have raised hundreds of millions after you've gone through several iterations to prove to investors you know what you're doing.
It's unrealistic to expect these chips to compete with modern manufacturing standards. Still, it's very impressive the progress RISC-V has made in the last few years. It's actually a viable option for many projects now.
i guess this chip is not for high end gaming machines or servers, but rather cars, industrial machine controlling, smart fridges, that kind of stuff. during covid production of many appliances ground to a halt because of various chip shortages. now what if for some reason asian chips became unavailable in europe (wars, natural catastrophes, ...)? cheap and easy to build is far more important than high end performance here.
That's kind of not good news. I was hoping for 4nm to have some alterative to Intel/AMD/Apple.
