ATI Radeon HD 4000 Series discussion

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

Again... comparing across different architectures.


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.



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.

Maybe the GPU was disigned to 512bit, because you can't know when you create the ship if the GDDR5 will be ready or not.

Maybe it's a 512bits GPU with 256bits GDDR5.

But i heard that the GPU could get out with GDDR3/4 memory if the GDDR5 is not ready, and the GPU will be a 4850, the 4870 may wait the GDDR5 about one month.

i think the GPU is ready, the GDDR5 not, and AMD is waiting for RAM.

I suport AMD/ATI, i'm gonna buy a 4870, the 3870 is a great videocard and even if i don't need more 3D power, i'm gonna buy it. And if AMD do only a dual GPU in High end and a 4870 cheap it's going to be very interesting
