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.
The first Ascalon silicon, Atlantis, will not be the latest process. As you say, that will impact performance. But there are plans for other chips to use newer process, and of course you can license and do what you like.
The point is that RISC-V is not limited to lower performance by the ISA.
