"We first covered the launch of the new NVIDIA GeForce 9800 GTX+ on June 20, 2008. Launched right after the GT 200 series of graphics cards, the GeForce 9800 GTX+ is die-shrinked version of the venerable NVIDIA G92 GPU, used in cards like the GeForce 8800 GTS 512MB and the GeForce 8800 GT.

Thanks to the die-shrink from 65 nm to 55 nm, NVIDIA was able to further boost the core and shader clock speeds of the GPU by 9.3%. Everything else was unchanged, including the memory clock which remained at 1.1 GHz. Hence, NVIDIA called it the GeForce 9800 GTX+ (Plus), instead of the GeForce 9900 GTX."
