Benchmarking Intel's UXA, round 2

Debian unstable just upgraded to xserver-xorg-video-intel version 2.8.0. (released two days ago -- who says Debian is out of date?) This release is notable in that it removes support for EXA and DRI1, leaving only UXA and DRI2 for acceleration. Considering my previous benchmarking attempts, I thought it was only right to check the new drivers.

• UXA, 2.8.0 (new-school)
  • 100 runs: 18.17 seconds
  • 200 runs: 38.32 seconds

UXA on 2.8 is still slower than EXA on 2.7, but not by much. Notably, it's much faster than UXA on 2.7. I'm sure further releases will only lower these numbers further.
