That's a huge difference in area.
In line with SiFive tradition, always huge area advantage against any given performance point's ARM design counterpart.
I am amazed they manage to still keep this sort of advantage up, while tackling higher and higher performance points.

- snvzz 3y agoIt is a good thing that at least the ISA managed to catch up with every important ARM or x86 feature yet avoid that baggage creep. Microarchitectures might need a full redesign once in a while, but if it can keep its RISC-V software moat, that's alright. Worked for x86 so far.
