128mb vs. 256mb head-to-head in OSX games at barefeats.com

I know the performance delta of the 256mb and 126mb VRAM MBPs is a hot topic around these parts, so I thought I'd post the first controlled testing I've seen so far, at http://www.barefeats.com/rosa03.html. barefeats has run both machines through stress tests in a variety of what looks to be OSX versions of games based on the frame rates.

The results are interesting -- there is an average 5% FPS difference between the two, with a max of 9%.

It would be interesting to see some similar controlled benchmarking in a Windows environment, (again, I'm just assuming these are OSX versions) but so far, at least according to this test, it looks like the 128mb version is not too shabby when compared to it's bigger brother.

 

I think the performance difference would probably be greater on more recent games. Wow and UT2004 probably don't need that much in terms of video ram.

Also, turning on AA and AF would likely make the difference even greater as well.

 

The speed of the GPUs are the same, well because it is the same GPU. Memory on the GPU is different, as different games are more memory hungry than others. A simple straight up comparison will never give you conclusive results on this though.

 

Sure it will. Just not using older games or those that don't rely so heavily on the GPU. Hell, WoW will run on integrated graphics! Need to see some Oblivion/Dark Messiah torture tests. Then we'll see what's what.
