Whats keeping ATI from using on core RAM

ATI successfully implemented that 10mg of RAm on the core of the xbox 360 gpu.

What is holding ati back from starting to use it on PC cards? I heard it helped improve AA performance to closely give 2x and even 4x for free.

Sounds like something ati should start implementing.
 
Have you played a 360 game? Almost none of them have any aa or af, and some are resorting to running resolutions lower then 720p(like Halo 3). So I wouldn't say it gets "free' anything. On high end cards 2x and 4x don't cause much of a hit, atleast not enough to go much under 60 fps.

It would add to the cost of hardware as well, and AMD is behind enough as it is right now. It speculated that future generations of hardware will implement this though.

currently the 2900 plummets with any AA on

It is a high-end card, games that will come out in a couple of years will use shader aa. Who will be laughing then huh?!? ;)

Those games will also be using more shaders, which means less shader procs available to do AA resolve.
 
I agree. I know shader based AA will have more flexibility, but what's wrong with the current method of ROP based AA? It's there. It's dedicated hardware. Why not use it?

LOL...so you think it'll be a competitive card in a couple years? Won't it be a bit dated by then? :p

In all seriousness though, I own a 2900xt as well so I have no inherent hate for it :) My wife loves it for WoW and such!
 
EDRAM is extremely un-usful at the high end rez everyone wants on their high end cards, period. You have to program to use it sucessfully, it costs alot of money, more heat to exchange on the HS with the GPU, costs too much to place on a low end GPU (possibly the only place it would be good on).

Face it, the only place this thing will ever be seen is on a console that dedicates itself on lower rez's and cheaper-then-hardware-cost ideal's.
 
yeah cost would be a huge factor, imagine the failure rates, just look at how much more the ati mobile cards cost to manufacture, if they have 64mb of ram go bad... then to the garbage or recycle they go...

It will be cool when everything is more closely integrated tho, processor videocard and system ram all in one chip :) Upgrading will be a pita then tho
