NVIDIA's upcoming GeForce G 210 and GT 220 40nm GPUs seem to be on-track for a smooth launch with images of NVIDIA reference design cards appearing on the web. Featuring half-height low-profile PCBs and single slot coolers, it does say a bit about its thermal and power properties. Other features include support for DirectX 10.1, OpenGL 3.0, and CUDA. The reference GT 220 design includes VGA, HDMI, and DVI ports, while the reference G210 trades the HDMI port for a DisplayPort output.
