the current highest performance RISC-V systems you can buy off a shelf are equivalent to a raspberry pi 5 so they're not terribly behind. in terms of IPC, currently available RISC-V cores are already basically on par with Zen 3 and Apple M1 from what i understand and Jim Keller believes that RISC-V will be the one that leads the way for raw performance.
SiFive P870 and Tenstorrent Ascalon are pretty much Zen 3. Tenstorrent is supposed to be releasing silicon soon. You can license their cores now. SiFive says customers have the P870 already but I am not sure who those are.
Are they on the latest silicon process?
Because, without neglecting the micro-architecture, we all know how critical the silicon process is for high-end performance.
