Now the SD has effectively entered the ARM market w/ something powerful, we're going to need to see something from RISC-V developers like SiFive to step-up up
Until it sees something other than a CPU designers screen and actually reaches taping or someone funds the fabbing of the design, its just a prediction based on simulations. Even if it does reaches taping, AMD will have moved on to something else and more performant. Being a RISC-V, it probably outperforms any application that takes advantage of a massive super pipelines.
The upcoming Veyron V2 CPU coupled with the Imagination Technologies GPU can scale up to 192 cores and, thanks to new RISC-V RVA23 extension support, it is expected to beat AMD's EPYC Bergamo 120-core / 256-thread processors in certain workloads.
