What do you want? 300GB/s memory bandwidth?
Is the GTX 280 capable of supporting the GDDR5 memory modules? Or is the design/fab not capable of using that type of memory?
Thanks, I wasn't sure because I haven't heard too much regarding the possible GTX280b (whatever they name their 55nm card) with GDDR5.I don't have a link, but seem to recall seeing a post stating the G200 doesn't support GDDR5.

if its still on a 512bit bus then it will not use gddr5 because there is no need for the additional bandwidth and cost. nvidia probably went with large bus width because they were unsure what the availability and cost of gddr5 would be when they were designing the GTX280.Thanks, I wasn't sure because I haven't heard too much regarding the possible GTX280b (whatever they name their 55nm card) with GDDR5.
still not going to help anything on the GTX280 and would only add more cost. the 4850/4870 if ran at the same core clocks only show about a 5-7% performance gain going from 2000mhz gddr3 to 3600mhz gddr5.Read the post on Evolucion8's explanation of how gddr5 isn't just about memory bandwidth.
It allows the GPU to offload certain calculations that the gddr5 can compute faster that aren't just for memory bandwidth relations.
i think the question is would it be cheaper to nock it down to a 256bit bus using gdr5 instead of the 512 using gdr3, which i have no clue
Plus, the memory controller on the GT200 has not been modified to support longer burst rates yet, which means it won't support even GDDR4, without even considering 5. You think nVidia really did not want to use GDDR4 initially for their top end and make the G92 (8800GT/GTS) the new top dog?

256-bit bus would lower the die size considerably, hence help its yields a lot
eh, how do you figure that?
