It may be hardware variation, but it'll also have to do with the real world not being a static nor ideal condition for anything electrical. Primarily, there will be differences in EMI (electrical noise) between runs, meaning that the connections run at varying speeds based on how much error correction they have to do. Also, differences in quality of Ethernet cables could be a factor, relating to the EMI issue.
That being said, if these results are more-or-less repeatable with similar results on the same pair of boards but different cables, it probably is hardware variation between boards.
