In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8400 GS Rev. 4 EVGA 1GB Edition are marginally better than the Nvidia GeForce 6800 XT.

The 8400 GS was released over a year more recently than the GeForce 6800 XT, and so the 8400 GS is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 6800 XT.

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 8400 GS has 768 MB more video memory than the GeForce 6800 XT, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the 8400 GS also has superior memory performance overall.

The GeForce 6800 XT has 1.6 GB/sec greater memory bandwidth than the 8400 GS, which means that the memory performance of the GeForce 6800 XT is marginally better than the 8400 GS.

The GeForce 8400 GS Rev. 4 EVGA 1GB Edition has 16 Shader Processing Units and the GeForce 6800 XT has 12. However, the actual shader performance of the 8400 GS is 19 and the actual shader performance of the GeForce 6800 XT is 4. The 8400 GS having 15 better shader performance and an altogether better performance when taking into account other relevant data means that the 8400 GS delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 6800 XT.

The GeForce 8400 GS Rev. 4 EVGA 1GB Edition requires 40 Watts to run but there is no entry for the GeForce 6800 XT. We would recommend a PSU with at least 350 Watts for the 8400 GS.

Overclock: Central Unit
The Central Unit still runs at 520MHz.

Overclock: Memory Clock
The Operating Memory Clock is now of 600MHz while the Frame Buffer was doubled to 1GB: a gimmick which doesn't yield any performance boost and can be considered market to lure consumers into paying more for the same product.

Cooling Solution
The Cooling System remains the same.

Performance
Benchmarks indicate a 3% performance over the reference GeForce 8400 GS Rev. 4.
