So, @bradfa pointed out elsewhere some details of the SolidRun aarch64 workstation are public. Neat! Even some preliminary performance numbers. Not bad! Now let me just rip on Intel instead for a moment. My current workstation is a refurb'ed Dell with with dual Xeon E5-2670. And grabbing https://www.cpubenchmark.net/compare/Intel-Xeon-Silver-4108-vs-Intel-Xeon-E5-2670/3167vs1220 OH MY GOURD MY 7 YEAR OLD CPU BEATS THE 1 YEAR OLD ONE.
@trini @attilakinali to be fair to Intel, they do a good job of offering a broad range of performance in their CPU family offerings. Your E5-2670 seems to have retailed for about $1500 when it was current while the Silver 4108 is a ~$425 CPU of similar performance. The cooling needs are also likely lower on the newer part.
