ATI Radeon HD 4000 Series discussion

Why would it reduce performance?

Because it would be lowering the core clockspeed, aka the ROP and TMU speed.

I mean look at how well the 96gt performs, and it only has 64 shaders.

Again... comparing across different architectures.

I pretty sure unless games are coded to make use of all those shaders, no matter how good the drivers are we probably won't see as much as a boost as we'd like.

Do you understand how ALUs work?
The game doesn't need to be "coded" for the shaders, at least the way you are thinking about it.

Nah I highly doubt it, more likely than not gddr5 is the reason for the delay, besides fuad has posted I believe 3 times now that the rv770 will see the return of the r600's ringbus so that means there's a possibility of a gddr3 4870 with a 512 bit memoy bus. I generally don't trust the really shaky things fuad says, but when he posts the samething multiple times it generally turns out to be right

GDDR5 is good and ready to go.
RV770 IS a 256bit GPU. Seeing as how they will be using the RV670 PCB with some slight component changes.
