Leadtek joined the GeForce GT 600 launch party with three new Winfast series graphics card models, based on the GeForce GT 630, GeForce GT 620, and GeForce GT 610 (pictured in that order, below). The GT 630 card (model: LR2741), dons a full-height PCB, a double-slot cooling solution, 1 GB of SDDR3 memory, and clock speeds of 810/1620/1600 MHz (core/CUDA cores/memory effective).

The GeForce GT 620 based card (model: LR2740), is low-profile capable, its cooling solution consists of an active fan-heatsink. Like the GT 630 model, this card utilizes 1 GB of SDDR3 memory as well. It comes with clock speeds of 700/1400/1333 MHz. Lastly, there's the GT 610-based card (model: LR2739), which packs a much more compact fan-heatsink, 1 GB of SDDR3 memory, and clock speeds of 810/1620/1066 MHz. All three cards provide DVI, D-Sub, and HDMI display outputs.
