I wager that statement would be turned on it's head if we restricted the comparison to chips of similar transistor density. Fast ARM chips do exist, as ARMv8 designs fabbed on 5nm TSMC with noncompliant SIMD implementations. If there were RISC-V chips in the same vein as Ampere or Nvidia's Grace CPU, I don't see any reason why they couldn't be more competitive than an ARM chip that's forced to adhere directly to the ISA spec. RISC-V hedged it's bet by creating different design specs for smaller edge applications and larger multicore configurations. Right now ARM is going through a rift where the last vestiges of ARMv6/7 support is holding out for the few remaining 32-bit customers. But all the progress is happening on the bloating ARMv9 spec that benefits nobody but Apple and Nvidia. For all of ARM's success in the embedded world, it would seem like they're at an impasse between low-power and high-power solutions. RISC-V could do both better at the same time.
