AMD Cayman info (or rumor)

[Nintendork]

If the 6970 does have less shader units then thats very disappointing. And why are they still using a 256 bit memory bus? I'm not impressed at all.

256bit*5700Mhz GDDR5 = 182.4GB/s
384bit*3800Mhz slow GDDR5 = 182.4GB/s

With GDDR5 there's no reason to increase bus width unless you have an inefficient memory controller that can't handle high speed GDDR5 such as nvidia. Just with that a chip cost more-take more space in die --> bigger die- for the same performance.


I see you are new to AMD arq improvements. See Barts HD6800 for example. Cayman brings even more efficiency than Barts.

You already can with any HD6000.
