Nvidia's GeForce 9800 GX2 is still kicking around e-tail stocks, but dual-GPU offerings based on the green team's newest architecture have yet to materialize. You might chalk that up to the GT200 graphics processor's prodigious size or its power consumption, but the fact remains: Nvidia still lacks a competitor to AMD's Radeon HD 4870 X2.
According to Fudzilla, that competitor may finally arrive before the end of this year. The site quotes "Far Eastern sources" as saying Nvidia is "talking about a dual chip solution that might come in December." Supposedly, this card will feature a pair of die-shrunk GT200 GPUs based on 55nm process technology. Nvidia relies on TSMC's 65nm process to produce current GT200 GPUs, but it already has 55nm parts shipping (like the GeForce 9800 GTX+). AMD, meanwhile, has used 55nm tech for all of its Radeon HD 3000- and 4000-series offerings.
Reports about the 55nm GT200 die-shrink started appearing about five months ago, and they hinted the chip would roll out in the late summer or early fall. According to an ELSA roadmap that appeared on the web in September, though, the die-shrink might not actually launch until mid-November at the earliest. The (blurry) roadmap seems to pin a 40nm or 45nm GT212 chip in early 2009, too.
