That "Xeon" is a very old (10-year old) quadruple-core (8-thread, i.e. 8 "virtual CPUs") desktop Haswell CPU rebranded as "Xeon". A current Intel NUC Pro with a Core i3 CPU would be a much faster (67% faster ST, 43% faster MT) dedicated server than this one and it would cost to own less than $500 with DRAM and SSD, so about $8 per month for a 5-year lifetime (so the performance per $ would be at least 5 to 6 times higher than that of the compared Intel server).

That "Xeon" is a good comparison point only because it was available for them in the same price range, not because it would be representative for the performance of any modern x86 CPUs. Also the "Epyc" is probably a very old model.

Somebody who wants to spend their money for cloud services as efficiently as possible should better ensure that it is possible to migrate back and forth their applications between x86 and ARM instances, because which one is cheaper for a certain performance at a given time depends a lot on non-technical reasons, so it is unpredictable which will be cheaper a few months later.
