The results of Mesa 8.0.2 vs. 8.1-devel Git as of May aren't too interesting, hence why the results weren't quick to be published on Phoronix. Those interested can find them on OpenBenchmarking.org or facilitate your own comparison with the Phoronix Test Suite by simply running phoronix-test-suite benchmark 1206129-SU-INTELIVYB10. Benchmarking was done from the Intel Core i7 3770K with its Intel HD 4000 graphics (IVB / Gen7).
