nbench (source) is a great free Linux benchmarking tool for basic processor comparisons on Linux. Despite its utility, nbench is not a popular tool among reviewers and tech bloggers. Therefore, I have kept this list of results that I have collected, for reference. I will add to this over time as I benchmark more systems.
The “MHz” column is either the single-core “boost” specification for that processor, or the base clock if such is not available.
Sorted by “AllCore”, which adds the Integer and Floating scores, normalizes the score to the AC-MHz (All-Core “Boost”) column, multiplies by the core count, and grants 25% for SMT-enabled CPUs. This is meant to estimate the total performance of the CPU.
The spreadsheet is available here.
