Nvidia plans to launch two version of the Geforce 9600GT. The reference design has 512MB memory but some partners will launch a bit more expensive 1GB version.
Memory still plays an important role in a mind of consumer and ATI and Nvidia are already selling Radeon 3850 1GB as well as 8800GT with 1GB. Geforce 9600GT with 1GB doesn’t come as a big surprise as the memory got cheaper but unfortunately you cannot count on a huge performance increase with 1GB card over the 512MB.
Nvidia uses DDR3 memory with 256 bit memory interface and it was a time to move from rather limiting 128 bit interface that was used for years.
NVIDIA 9600 GT to be offered with 1GB of memory
If this news from Fudzilla is true, then some partners of NVIDIA are going to offer 1GB versions of the 9600 GT. Let me say that again – 1GB of frame buffer on a card with mid-range performance. If this is true, and performance differences between the 512MB and 1GB versions are what I am guessing they will be (~0-1%), this could be the worst idea I’ve heard in a long time.
