In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8600 GT 512MB GDDR3 are significantly better than the Nvidia GeForce 6800 GT Leadtek Edition.

The 8600 GT was released over a year more recently than the 6800 GT, and so the 8600 GT is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the 6800 GT.

The 8600 GT has 256 MB more video memory than the 6800 GT, so is likely to be slightly better at displaying game textures at higher resolutions. However, the overall memory performance is about the same.

The 6800 GT has 9.6 GB/sec greater memory bandwidth than the 8600 GT, which means that the memory performance of the 6800 GT is marginally better than the 8600 GT.

The GeForce 8600 GT 512MB GDDR3 has 32 Shader Processing Units and the GeForce 6800 GT Leadtek Edition has 22. However, the actual shader performance of the 8600 GT is 43 and the actual shader performance of the 6800 GT is 8. The 8600 GT having 35 better shader performance and an altogether better performance when taking into account other relevant data means that the 8600 GT delivers a marginally smoother and more efficient experience when processing graphical data than the 6800 GT.

The GeForce 8600 GT 512MB GDDR3 requires 46 Watts to run but there is no entry for the GeForce 6800 GT Leadtek Edition. We would recommend a PSU with at least 350 Watts for the 8600 GT.

GPU Mini Review

Mini ReviewGeForce 8600 GT 512MB GDDR3 is one of the many variants of the fast-middle-class GeForce 8600 GT.
On this version, the GPU is equipped with 512MB of standard GDDR3. The architecture allows the use of 512MB, since the GPU's processing power is strong enough and the memory controller is up for the task of processing 512MB. Therefore, the performance is superior to the 256MB version and any other version of DDR2, including 1GB.
However, and due to its architecture limitations, modern demanding games will require reduced settings, even if they don't require more than 512MB of video ram. Very Demanding games like Metro 2033 are only playable at the lowest settings.
GeForce 6800 GT Leadtek Edition is a Special Edition of the GeForce 6800 GT. See the standard version for more information about it.
The only difference is the output which is now Two DVI instead of VGA and one DVI.
Therefore, the performance is exactly like the standard version and so most games will require reduced settings, due to the limited memory size and weak power processing, considering today's standards and needs.
