RISC-V is the future of processors
I’d very much like me some open source hardware. On a related note, this is an interesting write up on what makes M1 so fast, and in large part it comes down to using a RISC instruction set. Since all the instructions are the same length, it’s possible to process them in batches, and efficiently identify what instructions have inter-dependencies and what don’t. This means you can process independent instructions in parallel. On the other hand, CISC architecture precludes doing this because you can’t efficiently preprocess the instructions to figure out what ones can be parallelized.
Thank you for the info!
Noice. Does anyone remember if that movie is decent? I saw it a long time ago and forget.
Performance wise it is still very underwelming even with a lot of closed source extensions: https://www.phoronix.com/scan.php?page=article&item=hifive-unmatched-benchmarks&num=1
Keep in mind RISC-V is an architecture and not a processor. That’s like saying ARM is slower than x86. If you said that everyone would say “OK, comparing which implementations?”
Yes, but this is pretty much the fastest market available RISK-V CPU and it is absolutely destroyed performance wise by a RasberryPI 400. And in addition this CPU uses a lot of close-source extensions to increase performance.
I am hopeful that RISK-V might at some point be useable as a main CPU, but it is still a long way before that will be feasible as far as I can tell.
