MicroMagic is pretty interesting to me in the RISC-V space: https://arstechnica.com/gadgets/2020/12/new-risc-v-cpu-claim...

They are getting perf-per-watt numbers that are ahead of everyone...albeit with a single core and no real 3rd party verification.

Some of the group had worked on Sparc at Sun, and they had previously sold themselves to Juniper for $260M, then regrouped some time afterwards.

It's worth noting that Micro Magic's design tools are likely what allowed them to claim these numbers. Some of the claims they make about their software are pretty impressive, but it mainly boils down to intelligent placing/routing techniques that mirror fully custom hand-made silicon designs but are actually designed by the computer: http://www.micromagic.com/datasheets/PDFs/DPC_3page_Layout.p...

It seems like their design workflow is ahead of the rest of the field.

AI models are also conducting placement of components now.

The previous discussion of that article on HN seemed to point to those numbers being totally unsuported. https://news.ycombinator.com/item?id=25262834

Obviously I would love those perf-per-watt numbers to be correct, but it doesn't seem like they have shown it yet.
