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 XT .

The X1650 XT was released over three years more recently than the 8600 GT, and so the X1650 XT is likely to have far better driver support, meaning it will be much more optimized and ultimately superior to the 8600 GT when running the latest games.

The 8600 GT has 256 MB more video memory than the X1650 XT, 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 memory bandwidth of the Radeon X1650 XT and the GeForce 8600 GT 512MB GDDR3 are the same, which means the X1650 XT and the 8600 GT have equal limitations when it comes to graphical data transfer.

The Radeon X1650 XT has 24 Shader Processing Units and the GeForce 8600 GT 512MB GDDR3 has 32. However, the actual shader performance of the X1650 XT is 8 and the actual shader performance of the 8600 GT is 43. 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 X1650 XT.

The Radeon X1650 XT requires 55 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 X1650 XT. The X1650 XT requires 9 Watts more than the 8600 GT to run. The difference is not significant enough for the X1650 XT to have a noticeably larger impact on your yearly electricity bills than the 8600 GT.

GPU Mini Review

Mini ReviewRadeon X1650 XT is a middle-class GPU based on the 80nm variant of the R500 architecture.
It's based on the RV560 Core and offers 24 Pixel Shaders, 8 TMUs and 8 ROPs, on a 128-bit of standard GDDR3. The central unit runs at 525MHz and the memory clock operates at up to 700MHz.
It's therefore an overclocked Radeon X1650 GT with a 256MB frame buffer and performs much better than all the other X1600/X1650 GPUs.
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.
