i can't say for others - but i have written 2 tools that basically give u a
reasonable idea of overall render accel

http://www.rasterman.com/files/render_bench.tar.gz

is an old benchmarker that pits xrender against software equivalent rendering.
it gives one view of gneral render performance as opposed to "diy" in software
client-side.

another (more recent and more expansive) is evas - it has full xrender suport
as well as software rendering, opengl, directfb, etc. etc.

you basically can just tun the test program (that sits and benchmrks each
engine) and see the benchmark values u get at the end.

http://enlightenment.freedesktop.org/fetch.php?file=evas-0.9.9.023.tar.gz

- just bild, install then run the evas_*_test programs and they will spew out a
benchmark to stdout. the higher the value - the faster the engine's rendering.
