Too bad, A72 is the sort of thing found in $49 SBC's these days. For the price, it would have been nice to see at least A73, but at least its not an A53.

A73 isn't for servers and I don't see any server/embedded SoCs with A75 yet, so Amazon isn't exactly behind.

True, most server ARM processors that come to mind are custom (or at least semi-custom): Ampere, Centriq, ThunderX2. Trying to map them to A72/73/75/76 is perhaps short sighted since those are primarily smartphone cores - we'll have to wait and see how they perform in real world tests.

> at least its not an A53

Indeed. A72 is like the minimum viable core :) It's no eMAG or ThunderX2, but it's kinda comparable to the original ThunderX.

Probably should have done a lscpu instead. On recent arm distro's lscpu knows how to decode the part/variant/etc and it also pays attention to the cache and numa topology.

What does cpuinfo display when the CPU lacks the cpuid feature?

Arm processors don't have a cpuid instruction, but they do have a number of ID registers that provide similar information (e.g. MIDR_EL1, REVIDR_EL1).
