Best single-core performance servers with 4 GiB of memory

This is a manually curated list of low memory (4 GiB) servers with the best single-core performance as per stress-ng's div16 CPU burning method.

Note that servers using the same CPU model at the same vendor were deduplicated, and only the cheaper options were kept -- usually with lower number of physical cores (e.g. from AWS's m7a.medium and c7a.large showing only m7a.medium with a single core; or from c6i.large, c6in.large, and c6id.large showing only c6i.large).
