In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8600 GT 512MB GDDR3 are significantly better than the AMD Radeon X1800 Series 256MB.

The 8600 GT was released over a year more recently than the X1800 Series, 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 X1800 Series.

The 8600 GT has 256 MB more video memory than the X1800 Series, so is likely to be slightly better at displaying game textures at higher resolutions. However, overall, the X1800 Series has superior memory performance.

The X1800 Series has 22.4 GB/sec greater memory bandwidth than the 8600 GT, which means that the memory performance of the X1800 Series is slightly better than the 8600 GT.

The GeForce 8600 GT 512MB GDDR3 has 32 Shader Processing Units and the Radeon X1800 Series 256MB has 16. However, the actual shader performance of the 8600 GT is 43 and the actual shader performance of the X1800 Series is 5. The 8600 GT having 38 better shader performance is not particularly notable, as altogether the X1800 Series performs better when taking into account other relevant data.

The GeForce 8600 GT 512MB GDDR3 requires 46 Watts to run but there is no entry for the Radeon X1800 Series 256MB. We would recommend a PSU with at least 350 Watts for the 8600 GT and a PSU with at least 450 Watts for the X1800 Series. The X1800 Series has been recommended a PSU with 100 Watts more than the 8600 GT. The difference is significant enough that the X1800 Series may have an adverse affect on your yearly electricity bills in comparison to 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.
Radeon X1800 Series 256MB is not a GPU but instead a combination between Radeon X1800 GTO, Radeon X1800 XL and Radeon X1800 XT whose rank is a balance between the three and that exists for System Requirements purposes only.
