RADEON 9600 XT 128MB “Bravo Edition” has its memory clocked at whopping 760MHz, up 160MHz from ATI’s suggested speed. RADEON 9600 XT with 256MB “Bravo Edition” has VIVO functions in addition to a slight boost of memory frequency to 680MHz. Additionally, Power Color will equip ordinary RADEON 9600 XT graphics cards with 2.8ns memory, a slight improvement over 3.3ns offered by Canada-based VPU designer.A faster memory bus should help Power Color's 9600 XTs compete with NVIDIA's recently-released GeForce FX 5700 Ultra, whose memory is clocked at a whopping 900MHz.
Thus far, Power Color is the only manufacturer to unveil Radeon 9600 XT cards with faster memory than ATI's reference design, which suggests that ATI won't be changing the spec for its cards or those of its partners. However, if Power Color's "Bravo Edition" cards are able to leverage significantly better performance from a faster memory bus, other card manufacturers may consider tweaking the memory offered on their own cards.
