In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 6800 XT are noticeably better than the Nvidia GeForce 9400 GT.

The GeForce 9400 GT was released over three years more recently than the GeForce 6800 XT, and so the GeForce 9400 GT is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the GeForce 6800 XT when running the latest games.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The GeForce 9400 GT has 256 MB more video memory than the GeForce 6800 XT, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the GeForce 9400 GT also has superior memory performance overall.

The GeForce 9400 GT has 1.6 GB/sec greater memory bandwidth than the GeForce 6800 XT, which means that the memory performance of the GeForce 9400 GT is marginally better than the GeForce 6800 XT.

The GeForce 9400 GT has 16 Shader Processing Units and the GeForce 6800 XT has 12. However, the actual shader performance of the GeForce 9400 GT is 9 and the actual shader performance of the GeForce 6800 XT is 4. The GeForce 9400 GT having 5 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 9400 GT delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 6800 XT.

The GeForce 9400 GT requires 50 Watts to run but there is no entry for the GeForce 6800 XT. We would recommend a PSU with at least 300 Watts for the GeForce 9400 GT.

GPU Mini Review

Mini ReviewGeForce 9400 GT is a middle-class GFX part of the GeForce 9000 Series released by NVIDIA in 2008.
The performance is very limited due to the architecture itself and so most demanding games are only playable at low settings while very demanding games, might be unplayable, even at the lowest settings.
The groundbreaking new NVIDIA GeForce 6800 graphics processing units (GPUs) and their revolutionary technologies power worlds where reality and fantasy meet; worlds in which new standards are set for visual realism and quality, performance, and video functionality. The GeForce 6800 GPUs deliver powerful, elegant graphics to drench your senses, immersing you in unparalleled worlds of visual effects for the ultimate PC experience.
