Could you summarize the main architectural (not implementation) differences between arm and risc-v that apply to being a good/poor match for mobile in particular?
- jacquesm 6y agoI actually don't think there are any at the lowest level, it's mostly a matter of ARM being able to reduce power consumption by aggressively throttling down the clock rates and various advanced sleep modes. In principle you should be able to do this with any CPU, given a roughly equal transistor count power consumption should be close. Obviously ARM is much further along in the practical implementation of these features.
- imtringued 6y agoARM has big little on every chip except embedded ones. The mix of super scalar and in order CPUs significantly improves power consumption during idling.
