I have the basic benckmarks for Raspberry Pi version 1, 2 and 3, and here is the comparison, all the benchmarks on different Pis are using the same operating system / package, so there won’t be a difference from the version of software.
The testing platform:
RASPBIAN JESSIE
Version: February 2016
Release date: 2016-02-26
Kernel version: 4.1
Since I just did these benchmarks on Raspberry Pi 3:
https://www.peterdavehello.org/2016/03/raspberry-pi-3-model-b-basic-benchmarks/
The Raspbian and all the softwares are up to date, so the benchmark results of Raspberry Pi 3 are just copied from that post, they are the same result. The results from Pi 1/2 are whole new tested, in fact they are very close to the test results I did before, I would say they are all in the tolerance scope, so I’ll just ignore the detail of the benchmarks, only focus on the final results, the performance.
