In terms of overall gaming performance, the graphical capabilities of the Nvidia GeForce 8600 GT 512MB GDDR3 are significantly better than the AMD Radeon X1650 GT.

The Radeon X1650 GT was released less than a year after the 8600 GT, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The 8600 GT has 384 MB more video memory than the Radeon X1650 GT, so is likely to be slightly better at displaying game textures at higher resolutions. This is supported by the fact that the 8600 GT also has superior memory performance overall.

The 8600 GT has 9.6 GB/sec greater memory bandwidth than the Radeon X1650 GT, which means that the memory performance of the 8600 GT is marginally better than the Radeon X1650 GT.

The Radeon X1650 GT has 24 Shader Processing Units and the GeForce 8600 GT 512MB GDDR3 has 32. However, the actual shader performance of the Radeon X1650 GT is 6 and the actual shader performance of the 8600 GT is 43. The 8600 GT having 37 better shader performance and an altogether better performance when taking into account other relevant data means that the 8600 GT delivers a slightly smoother and more efficient experience when processing graphical data than the Radeon X1650 GT.

The GeForce 8600 GT 512MB GDDR3 requires 46 Watts to run but there is no entry for the Radeon X1650 GT. 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 X1650 GT.

GPU Mini Review

Mini ReviewRadeon X1650 GT is a middle-class GPU based on the 80nm variant of the R500 architecture.
It's based on the RV560 Core and offers 12 Pixel Shaders, 8 TMUs and 8 ROPs, on a 128-bit of standard GDDR3. The central unit runs at 400MHz and the memory clock operates at up to 400MHz.
It's expected to perform better than Radeon X1600 GPUs but the limited frame buffer might become a bottleneck in some of today's modern games and so it's not suited for them.
Some of today's games might be playable at medium settings although the low preset will have to be used on most. 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.
