With Digital Ocean the cpuinfo is obfuscated so figuring out exactly what you're running on requires a bit more trickery. With that said I honestly assume that the comparison is somewhat older AMD against even older Intel, so it's probably not a great representation of how the battlefield has evolved.

That said, Digital Ocean is doing their customers a disservice by making the Premium Intel and Premium AMD SKUs look similar. They are not similar. The performance gap is absolutely massive.
