None of them are competitive with Zen5 on a per core basis, if you compare the published SPEC results. 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/ https://www.ventanamicro.com/technology/risc-v-cpu-ip/ 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_Spring_2025_compressed.pdf 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".

This is not a problem. We are not running supercomputers at home. We need to be able Math software on modern open hardware We need to be able to program with a better assembly We need to be able to have predictable code generation from our compilers We need to play with a new architecture and port software as an exercise We need to have choice

  You need billions of operations per second for your electron apps to show you an alert telling you that you need to make an account on some website…

    Hahaha. I do not use many electron apps, only VScodium+Positron I would be fine on Risc-V, still there are many overlooked alternatives.

  We did just fine without those for many decades. It is the openess religion that eventually loses sight of what customers and businesses alike care about and keep alive on the market.
