In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8500 GT are very slightly better than the Nvidia GeForce 6800 XT.

The GeForce 8500 GT was released over a year more recently than the GeForce 6800 XT, and so the GeForce 8500 GT 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 GeForce 6800 XT and the GeForce 8500 GT have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce 8500 GT has 1.6 GB/sec greater memory bandwidth than the GeForce 6800 XT, which means that the memory performance of the GeForce 8500 GT is marginally better than the GeForce 6800 XT.

The GeForce 6800 XT has 12 Shader Processing Units and the GeForce 8500 GT has 16. However, the actual shader performance of the GeForce 6800 XT is 4 and the actual shader performance of the GeForce 8500 GT is 18. The GeForce 8500 GT having 14 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 8500 GT delivers a marginally smoother and more efficient experience when processing graphical data than the GeForce 6800 XT.

The GeForce 8500 GT requires 30 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 GeForce 8500 GT, but we do not have a recommended PSU wattage for the GeForce 6800 XT.

GPU Mini Review

Mini ReviewThe 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. GeForce 8500 GT is a middle-class GPU based on the 80nm variant of the first-shader unified architecture.
It's based on the G86 Core and offers 16 Shader Processing Units, 8 TMUs and 4 ROPs, on a 128-bit memory interface of DDR2. The central unit runs at 450MHz and the memory clock operates at 400MHz. It will consume no more than 45 Watt.
This GPU is only suited for a 1024x768 (or less) resolution. Most of today's games will only run at low settings and extremely demanding games might not run at all. DirectX 11 based games aren't supported and its performance will decrease drastically, as the resolution increases.
