Well I am a bit on both sides in this discussion. I think the 9600 is a welcome improvement, but it is arguable that they cheaped out. I just compared 3 radeon 9600 and there is quite a difference in performance. see:matticus008 said:Oh, so now you buy for Apple? We've been through this. If there were better hardware being sold to Apple with Mac-compatible firmware and BIOSes, they would use it. Not everything ATi makes is instantaneously compatible with what Apple makes. They buy what they are offered and fits the specifications Apple needs to fill. For the product lineup at Apple, the 9600 is par for course. Yes, the whole range is underpowered. But that's not some arbitrary decision Apple made. That's what there is to work with, nothing more or less.

- Card -------------- Engine Clock Speed (MHz)
- RADEON 9600 128MB --- 325
- RADEON 9600 PRO 128MB --- 400
- RADEON 9600 XT --- 500
If they really put in 'just' the 9600 it is quite cheaped out, since the XT wouldn't cost them significantly more. The performence of the XT is about 50% more. I have heard that apple even underclocks the XT in the mac version of the radeon, so card extensions are a bit more obsure in the mac world and you can't just compare mac cards to PC cards.
Hopefully you can overclock those Radeons in the iMac. (Very likely, if it will be newly manufactured chips)
But my point is: they should have put in radeon XT's.
So woog315, 25FPS in doom3 on a regular 9600 will likely not be possible. We just have to wait for the benches. I was hoping on the added benefit of 128mb ram (since doom3 loves it) and OpenGL tiger improvements (barefeats indicated a 20% gain).
