Server Comparison
Best multi-core performance servers
Manually curated lists of servers with the best multi-core performance as per stress-ng's div16 CPU burning method. This benchmark is a good indicator of how well a server can handle CPU-bound workloads that can perfectly scale to all available processor cores.
Servers using the same CPU model at the same vendor were deduplicated, and only the most general options were kept with similar memory amounts (e.g. from AWS's r6a.large, m6a.large, and c6a.large showing only m6a.large with 8 GiB of memory; similarly GCP's c2d-highmem-2, c2d-standard-2, and c2d-highcpu-2 showing only c2d-standard-2 with 8 GiB of memory).

LIMIT 25;Best single-core performance servers
Manually curated lists of servers with the best single-core performance as per stress-ng's div16 CPU burning method.
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 only the first).
