In terms of overall gaming performance, the graphical capabilities of the AMD Radeon X550 Series are marginally better than the Nvidia GeForce 6600 LE.

The Radeon X550 Series was released over a year more recently than the GeForce 6600 LE, and so the Radeon X550 Series is likely to have better driver support, meaning it will be more optimized for running the latest games when compared to the GeForce 6600 LE.

Both GPUs exhibit very poor performance, so rather than upgrading from one to the other you should consider looking at more powerful GPUs. Neither of these will be able to run the latest games in any playable way.

The GeForce 6600 LE and the Radeon X550 Series have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Radeon X550 Series has 4.8 GB/sec greater memory bandwidth than the GeForce 6600 LE, which means that the memory performance of the Radeon X550 Series is marginally better than the GeForce 6600 LE.

The GeForce 6600 LE has 7 Shader Processing Units and the Radeon X550 Series has 4. However, the actual shader performance of the GeForce 6600 LE is 2 and the actual shader performance of the Radeon X550 Series is 1. The GeForce 6600 LE having 1 better shader performance is not particularly notable, as altogether the Radeon X550 Series performs better when taking into account other relevant data.

GPU Mini Review

Mini ReviewSupercharge your gaming with the power of an NVIDIA GeForce 6600 GPU. The NVIDIA GeForce 6600 GPUs deliver best-in-class performance and advanced visual effects for next-generation games. The only GPU in its class with support for Microsoft DirectX 9.0 Shader Model 3.0 and with support for PCI Express, the GeForce 6600 delivers ultra-realistic effects, unmatched features, and rock-solid stability so you can play your game the way itís meant to be played.The Radeon R300 (introduced August 2002) is the third generation of Radeon graphics chips from ATI Technologies. The line features 3D acceleration based upon Direct3D 9.0 and OpenGL 2.0, a major improvement in features and performance compared to the preceding Radeon R200 design. R300 was the first fully Direct3D 9-capable consumer graphics chip. The processors also include 2D GUI acceleration, video acceleration, and multiple display outputs. R300 refers to the development codename of the initially released GPU of the generation. R300 and its derivatives would form the basis for ATI's consumer and professional product lines for over 3 years.
The integrated graphics processor based upon R300 is called Xpress 200.
