In terms of overall gaming performance, the graphical capabilities of the AMD Radeon X1900 XTX are significantly better than the Nvidia GeForce 8600 GT 512MB GDDR3.

The 8600 GT was released over a year more recently than the Radeon X1900 XTX, 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 Radeon X1900 XTX.

The Radeon X1900 XTX and the GeForce 8600 GT 512MB GDDR3 have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Radeon X1900 XTX has 27.2 GB/sec greater memory bandwidth than the 8600 GT, which means that the memory performance of the Radeon X1900 XTX is slightly better than the 8600 GT.

The Radeon X1900 XTX has 48 Shader Processing Units and the GeForce 8600 GT 512MB GDDR3 has 32. However, the actual shader performance of the Radeon X1900 XTX is 20 and the actual shader performance of the 8600 GT is 43. The 8600 GT having 23 better shader performance is not particularly notable, as altogether the Radeon X1900 XTX performs better when taking into account other relevant data.

The Radeon X1900 XTX requires 135 Watts to run and the GeForce 8600 GT 512MB GDDR3 requires 46 Watts. We would recommend a PSU with at least 350 Watts for the 8600 GT, but we do not have a recommended PSU wattage for the Radeon X1900 XTX. The Radeon X1900 XTX requires 89 Watts more than the 8600 GT to run. The difference is significant enough that the Radeon X1900 XTX may have an adverse affect on your yearly electricity bills in comparison to the 8600 GT.

GPU Mini Review

Mini ReviewRadeon X1900 XTX is a high-end GPU based on the 90nm variant of the R500 architecture.
It's based on the R580 Core and offers 48 Pixel Shaders, 16 TMUs and 16 ROPs, on a 256-bit of standard GDDR3. The central unit runs at 650MHz and the memory clock operates at up to 775MHz.
Its therefore a further clocked Radeon X1900 XT with a twice as big frame buffer and should only perform slightly faster.
Most of today's games might be playable at medium settings although the low preset will have to suffice on some. As it's not based on a Shader-Unified architecture, both DirectX 10 & 11 games aren't supported.
GeForce 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.
