The GT300/Fermi Thread

GTX 360 = 320bus x 4 = 1280MB
GTX 380 = 384bus x 4 = 1536Mb

?

I am a bit confused the white paper said "i think" fermi had 6 memory controllers so that means 256MB*6 memory controllers = 1.5gb in total 6 memory chips.

The bus should only show the bandwidth and not the capacity !!

GTX 360 "if made with a 320bus" can have 5 memory chips and that means 5* 256MB = 1.2gb in total of 5 memory chips one memory controller will be unused.
