Thanks to a chart posted over at VR-Zone, we now get a clearer picture as to NVIDIA's supposed movements across their GPU line-up throughout 2009.

We already know to expect the move to 55nm very soon with the G200b core on GTX 260, 285 and 295 graphics cards. But according to this chart it appears NVIDIA have no intent to settle on 55nm for long, rather treating it as more of a stepping stone to their superior GT212 core which will be 40nm based; this set to arrive during Q2'09 and will be exclusive to the performance and enthusist segments.

From there we should see the mainstream and value segments gifted with 40nm parts in Q3'09; namely the GT214, GT216 and GT218 cores. These cores will replace the existing G94, G96 and G98 cores. If you'd like to get the jump on a few specifics about the GT216 in particular, Expreview got hold of some interesting details just the other day which you can read about here.

Also set to be introduced during Q3'09 is a new IGP dubbed iGT209; this also to be 40nm based and will replace the current GeForce 9400/9300 mobo series.

The icing on the cake for the year comes in the form of the mighty GT300 which will take over the reigns from GT212. All that is said about GT300 at this stage is that it'll likely carry DX11 support given it won't show up until the end of next year.

Thanks to VR-Zone for the insight.
