The GT300/Fermi Thread - Part 2!

Same performance of course. Having the same bandwidth doesn't tell you anything. And there is no correct answer until we see hard numbers which is why I was asking why you think they need higher memory clocks. Maybe 160GB/s is more than enough. At least it's way higher than the previously rumoured 128GB/s.

well according to the numbers weve all seen, the 470 needs every little bit of additional perf it can get since it seems to be behind the 5870 in most scenarios...

Nothing is released to public yet, either the GPU or the box , some PR-hungry people leaks these unfinished products. They will fix it by the time of release.

Consider it as a beta-box.

which is what, in 2 weeks? they dont even have the box layout finished and plan to have thousands of them printed AND already shipped to distries and shops in 2 weeks? im finding it harder and harder to believe that the march 26 event will be a propper retail launch...

Considering the Tesla versions will have between 3GB and 6GB of GDDR5, I don't think the memory controller is anywhere near an issue.

capacity and speed are two different things...

Both the maximum memory allotment and the speeds would be affected if the controllers were "weak" as was alluded to before. If there were issues with the controllers, you wound not see each one paired up with up to 1GB of GDDR5.

right, there is some relation between speed and capacity, but just because there are 3 and 6gb cards you cant derive what speeds 1.5gb cards will clock at... for cpu/nb memory controllers this relation is common, but can you remember any differences in memory clocks in 1gb vs 512mb cards? and 512 vs 256, 128 vs 256 etc that was NOT based on how well the memory clocked? i cant!
