Not the first time that Nvidia has released completely different GPUs under the same name. Around 2006, they had 2 existing variants of the 8800GTS(320mb and 640Mb VRAM). A year later, they launched a new 8800GTS with a newer GPU and 512Mb. The newer card was much faster than the both older versions of the card. I can only imagine that this caused lots of confusion for uninformed consumers who might think 640 > 512 > 320.
