With Ubuntu 17.10 discontinuing the 32-bit desktop ISOs, here is the last time it makes sense comparing the Ubuntu 32-bit (i686) versus x86_64 performance.

Over the years we have looked at the 32-bit vs. 64-bit x86 Linux performance for curiosity sake, showing how x86_64 can be much faster than i686, and just providing these values for a reference look and if for some reason are still running 32-bit Linux software including the OS while the hardware is 64-bit capable. For this final benchmarking look are fresh numbers when doing a clean install of Ubuntu 17.10 32-bit compared to Ubuntu 17.10 64-bit.

A modest Lenovo ThinkPad X1 Carbon was used for this benchmarking with its Core i7 U Broadwell CPU and integrated graphics, 4GB system memory, and 120GB SSD. All tests were run via the Phoronix Test Suite.
