I hadn’t considered the RISC angle. Does RISC consistently use less power than CISC at given operations levels (MFLOPS, for example), or is there another/better way to make a power-consumption vs operations/performance comparison?
I realize this is kind of esoteric for my use-cases, but it would be useful for making projections to see if spending X dollars on Y number of Pi’s recoups the investment over a given period, just in power consumption.
E.G. If I can reduce my power consumption by 70% by switching to 3 Rpis, then I can recoup their cost in 2-3 years. Since my server needs replacing anyway, this seems like a no-brainer.
