In the great game of one-upsmanship played by the two major graphics chip makers, one of the most prized goals is being first to market with a new generation of technology. AMD captured that waypoint late last year when it introduced the first 28-nm GPU, the Radeon HD 7970.

However, there are advantages to being later to market, because the competition has already played its hand. Nvidia smartly took advantage of that dynamic when it unveiled the GeForce GTX 680 several months ago. The new GeForce managed—just barely—to outperform the 7970, while consuming less power and bearing a price tag $50 lower than the Radeon's.
