OK, it looks like Sapphire might have made a 128MB GDDR4 version of the HD 2600 XT.

Originally posted by F i L View PostWell... I was excited when I read that title. 4x the frame-rate on some of those tests would put them neck-n-neck with catalyst... but then I realized the test he's getting 4x performance on is the game that runs horribly slow on the OSS drivers. According to the Phoronix post, on the 6870 Reaction Quake get's 519 fps with Catalyst and 8 fps with Radeon... even if you quadruple that figure, you're still only getting 32 fps compared to Catalyst's 500+
Don't get me wrong, it sounds like a very promising patch, congrats and thank you to the developer... I hope it's just that game, but I'm not going to hold my breath until I see more benchmarks.

Thanks

[I'm curious though what, if any, external testing is even possible to assist developers, considering I expect it requires analysis of memory allocation/usage. I guess there are the piglit unit tests. Of if Michael (by that I mean the automated test suite) could be more granular in the driver performance testing (which features improved/regressed release to release). Not being a driver developer, I'm not sure what help I could really offer?]
[It always seems funny that Phoronix on the one hand talks about new features/improvements/and sometimes bugs that do not relate to the normal every day user, only those on the bleeding edge, but on the other hand often only runs benchmarks on default settings... such a contradiction]Last edited by Craig73; 01 November 2012, 02:58 PM.

this one works just fine
