When I see comparisons like this, the first thought I have is not the benchmarks, but rather what the most “heroic” real-world calculation of the day would have been on something like the Cray-1, and how to replicate those calculations today on something like a RPi. Weather/climate models? Rad-hydro? The fidelity would almost certainly be super low compared to modern FEA software, but it would be a fun exercise to tr…

It'd make more sense to compare with a RISC-V that has Vector 1.0. Because a vector machine is what it was.

I'd just bought the latest and most expensive Intel x86 CPU in 2013 and built myself a new rig. My wife walked into the office, "You're not working, I can tell that, but I'm not sure what you're doing?" she said looking at the graphs on my screen. "I'm calculating to see when my PC would have been the fastest on Earth. It looks like in 1992 it would be able to out-compute the latest Dept of Defense $90m supercomputer…

One of my favorite machines from Top500 is SystemX. https://www.top500.org/system/173736/ When it was commissioned in 2004, this array of 1100x Apple PowerPC 970 systems was the 7th most powerful computer on the list. It's Linpack Performance was 12,250.00 GFlop/s.
