For an older release of Blender was made an attempt on their forum:
2.61 Cycles render benchmark
with data put inside a spreadsheet:
Redone Blender Cycles Benchmark
but using PTS could become something simpler, automated (with the choice of more blend to test), updated and better organized.
At the bottom this part isn't much covered by the suite PTS put aside for some game and some specific test where isn't much clear how to interpret the result data into real graphics applications different from game.
