New Nvidia 40-nm GPUs are just for OEMs.
Last month Nvidia announced a handful of new mobile 200M series GPUs based on the still-current G200 architecture and built on the 40-nm process. It was only a matter of time before the 40-nm process would make it to the desktop parts, and today those products appeared on Nvidia's website.
Newly emerged are the GeForce GT 220 and GeForce G210, which are on the more modest side of speed and also carry an "OEM Product" tag clearly displayed – so don't expect to see this product in retail stores. It'll likely be packed in with new-built computers, as the tag-line below the product model name reads, "Every PC needs good graphics."
The lower-end G210 will have a core clock speed of 589 MHz, 512 MB of DDR2, 64-bit memory interface, 16 shader processors, VGA, DisplayPort and DVI. The GT 220 is beefier with a 615 MHz core clock, 1 GB of DDR3, 128-bit memory interface, 48 shader processors, VGA, HDMI and DVI. Both support DirectX 10.1, Open GL 3.0 and CUDA.
As they are OEM parts, prices are variable depending on the manufacturer.
