Unlike its rival AMD, Nvidia still doesn't have a top-to-bottom lineup of 28-nm graphics processors. Nvidia actually has just one variant of Kepler on the desktop: the GK104, which powers its GeForce GTX 670, 680, and 690 graphics cards. If we're to believe the latest report by VR-Zone, the GK104 will soon show up in a fourth card with an even lower price tag.
The site has posted a photo of an MSI GeForce GTX 660 graphics card, which seems to have a stubby circuit board and the same type of cooler design as MSI's existing GeForce GTX 670. The blower and the black, striped shroud look the same, at least; maybe the metal underneath is arranged differently. The image was apparently Photoshopped to highlight the card's single six-pin power connector (a supersized version of it is floating above the heatsink), but VR-Zone says its sources confirm the product indeed exists.
Too bad there's no word on pricing or performance. Considering the GeForce GTX 670 currently retails for at least $399.99, I'd expect a card bearing the GTX 660 label to sell for, say, $299 or $349—but no lower. Nvidia will probably need a smaller chip to get to lower price points and to compete with AMD's Radeon HD 7850 and Radeon HD 7700 series.
