Mobility 9000 32MB vs 64MB performance

Are there any video benchmark test that compare the 32MB to the 64MB version? I am still not sure whether I should get the 867MHz or the 1GHz 15" PB.
 
i'm quite interested in this as well. although the last update to the titanium pb's has been almost three months ago, i can't seem to find any articles or benchmarks about them.

i recieved my ghz tibook about ten days ago, it's equipped with the 64MB version of the mobility radeon 9000. i've tested most of my games on it. while all performed just fine on it, quake 3 was the only one where i enabled the frame counter and as i wasn't able to look at it all the time my numbers aren't to be taken too serious. at 10x7, max settings, "s_chunksize 4096" enabled in the config, i got around 120 fps with just walking around, about 100 fps with medium action. with major action going on fps were around the 80s.

the other games include: warcraft 3, diablo2, medal of honor allied assault, RtCW, the jedi knight II demo and Black & White.

i have yet to see choppy gameplay with this baby. ^^
 
As far as I know, the ati9000 mobility 32mb has just 64bit-ram while the 64mb version has a 128bit connection (got this info from ati-website). This is a big issue in performance, since the speed of the memory (whether clock or bandwidth) is mostly the bottle-neck
