NV40 and programmable tile sizes

[Ailuros]

Did it ever occur to either of you that certain optimizations perform differently in different scenarios and what may be a win on is a loss on others?

Combine that with Wavey's bandwidth comment and for me personally this case is closed 8)

I don't get it.

What I meant to say was, that both comments seem to make sense to me; each of it's own value of course.

I do believe that different approaches have both their advantages and disadvantages and I also think that for a 520MHz the XT has way too little bandwidth.

Am I the only one that had heard that NVIDIA initially targeted a 600MHz clockspeed? Let's ignore yields, heat or whatever else for a second; where would they had gotten the necessary bandwidth from?

If I assume that the 400-550MHz core/ram relativity is well balanced I'd need theoretically what kind of GDDR3 for 50% higher clockspeed?

R420's ram is only 10MHz faster than NV40's or not?

That was for the once planned 8x1 NV40, not for the chip known as NV40 now.

What was the targeted clockspeed for the NV40 now ?
