It appears I have mistaken C910 with a different core. I haven't found trustworthy benchmarks but T-head's own numbers of 6 DMIPS/MHz and 7 CM/MHz (Dhrystones and CoreMark - which leave much to be desired) compared to 4.27/3.32 DMIPS/MHz (??) and 5.75 CoreMark/MHz seems to agree with you. I have U74 Geekbench results [1] and would like to see the same from C910.
With that in mind, I agree that $1500 is a bit much.
[1] GB 4.5.0 40 (Crypt 7, Int 49, FP 27), but don't compare to Arm and x86 architectures as unlike them, the RISC-V code is missing a lot of optimization.
- snvzz 4y ago>U74 geekbench results What version of U74? It has changed over time. Not only it got faster (both per clock, and changes to allow for clock increases), but it also gained extensions like B at some point. This is particularly important with cryptography in mind; I would assume the crypt result is about that.
