> Which risc-v implementation is considered fast?
SpacemiT K3 is 2010 Macbook performance single-core, 2019 Macbook Air multi-core, and better than M4 Apple Silicon for AI.
So I guess it depends on what you are going to do with it.

SpacemiT K3 is 2010 Macbook performance single-core, 2019 Macbook Air multi-core, and better than M4 Apple Silicon for AI.
So I guess it depends on what you are going to do with it.
M4 is 38 TOPS at INT8 precision whereas SpacemiT K3 is 60 TOPS at INT4 precision so at best they would be equal in "AI" performance but they are not because the rest of the K3 chip is much less capable than M4 (as I would expect).
E.g. M4 total system memory bandwidth is 120GB/s whereas K4 is 51GB/s, single core memory bandwidth is 100-120GB/s vs ~30GB/s. M4 has 10 CPU cores and neural engine with 16 cores whereas K3 has 8 CPU cores and 8 "AI" cores, K3 clock frequency is almost half the clock frequency in M4 etc. etc.
But anyway thanks for sharing, always good to learn about new hardware.
