nbench (64-bit/32-bit/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, here is a list of processors I have benchmarked with nbench, for myself and others to reference. In the future, rather than making new posts, I will add to this over time as I benchmark more systems.
Sorted by sum of Integer and Float scores multiplied by the number of cores. Note that on the calculated columns, a 30% increase in score is given to HyperThreading-enabled processors to account for the theoretical benefit.
