Ubuntu vs. Fedora Linux On Lenovo's X1 Carbon With Core i7 Broadwell
It will be interesting to see what other Broadwell optimizations come for Mesa in the months ahead along with finally nearing OpenGL 4.0~4.2 compliance.
Fedora 21 interestingly had faster build times than Ubuntu 14.10 and 15.04 on this Broadwell system. For the other CPU bound tests, the results weren't too interesting given that the binaries on all three Linux distributions were being built under GCC 4.9.
