Guys from Overclockers.RU made some experiments with 128 MB card RADEON 9500 from Sapphire, as a result they converted it in... RADEON 9700 card!
Card on ATI RADEON 9500 have 128 bit or 256 bit bus, depending on a quantity of video memory. Since these boards are done on PCB from RADEON 9700, it equipped 64 bit half sized versions, which have exactly half of chips, from RADEON 9700, i.e., 128 bits. Then the 128 megabaytnye boards, which have 8 chips of memory, installed exactly as on RADEON 9700, have the "valuable" 256 bit bus of memory.
