RISC-V still seems overhyped to me. It would be nice to see working examples being used competitively.

- jacquesm 6y agoIt is work in progress on a very impressive trajectory.
- bsder 6y agoIt's effectively MIPS warmed over. And MIPS never went anywhere because it never cracked the cellphone market (which is where the real volume is). When someone puts out a RISC-V phone, you've got a battle on your hands. Until then, you're fighting over table scraps.
- jacquesm 6y agoI actually liked the MIPS architecture and used it for many years as my daily driver. True, it wasn't designed with mobile in mind, and ARM was a very good match there. But I don't see any reason why it could not be adapted to that.
- ithkuil 6y agoCould 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.
- imtringued 6y agoIsn't MIPS owned by a single company? How is that ever going to get traction if MIPS doesn't deliver exactly the types of chips that its customers want?
