Ascalon is about half as fast as Veyron V2, partially due to lower clock frequency (~2.6 GHz): https://riscv.or.jp/wp-content/uploads/Japan_RISC-V_day_Spri...
It's really more designed as a "we need a decently fast and efficient CPU for our AI accelerator" then a "let's build the fastes CPU possible".
Veyron V2 has comparable perf per GHz to Zen4/5, but at a lower clock frequency (N4: 3.25, N3: 3.85): https://www.ventanamicro.com/technology/risc-v-cpu-ip/
