alt Hacker NewsThe RISC-V ISA can be fast.
Tenstorrent Ascalon, expected later this year, is expected to be AMD Ryzen 5 speeds. Tenstorrent hopes to achieve Apple Silicon speeds in a few years.
The SpacemiT K3 is about half as fast as Ascalon and available in April. K3 is 3-4 times faster than the K1 (previous generation).
This should give you an idea about how fast RISC-V is improving.

I'd be pretty surprised if Ascalon actually hits Zen 5 perf (I'm gessing more like Zen2/3 for most real world workloads). CPU design is really hard, and no one makes a perfect CPU in their first real generation with customers. Tenstorrent has a good team, but even the "simple" things like compilers won't be ready to give them peak performance for a few years.

Assuming AMD, Intel, ARM, Apple in a few years haven't released new CPUs, otherwise the difference is the same as today.
