In terms of overall gaming performance, the graphical capabilities of the AMD Radeon X700 Series are significantly better than the Nvidia GeForce 6600 GT.

The GeForce 6600 GT was released less than a year after the Radeon X700 Series, and so they are likely to have similar driver support for optimizing performance when running the latest games.

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 Radeon X700 Series and the GeForce 6600 GT have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The GeForce 6600 GT has 4 GB/sec greater memory bandwidth than the Radeon X700 Series, which means that the memory performance of the GeForce 6600 GT is marginally better than the Radeon X700 Series.

The Radeon X700 Series has 8 Shader Processing Units and the GeForce 6600 GT has 11. However, the actual shader performance of the Radeon X700 Series is 2 and the actual shader performance of the GeForce 6600 GT is 6. The GeForce 6600 GT having 4 better shader performance and an altogether better performance when taking into account other relevant data means that the GeForce 6600 GT delivers a marginally smoother and more efficient experience when processing graphical data than the Radeon X700 Series.

The GeForce 6600 GT requires 48 Watts to run but there is no entry for the Radeon X700 Series.

GPU Mini Review

Mini ReviewThe Radeon X800 'R430'-based 110 nanometer series was introduced at the end of 2004 along with ATI's new X850 cards. The X800 was designed to replace the position X700 XT failed to secure, with 12 pipelines and a 256-bit RAM bus. The card more than surpassed the 6600GT with performance similar to that of the GeForce 6800. A close relative, the new X800 XL, was positioned to dethrone NVIDIA's GeForce 6800 GT with higher memory speeds and a full 16 pipelines to boost performance. R430 was unable to reach high clock speeds, being mainly designed to reduce the cost per GPU, and so a new top-of-the-line core was still needed. The new high-end R4x0-generation arrived with the X850 series, equipped with various core tweaks for slightly higher performance than the 'R420'-based X800 series. The 'R480'-based X850 line was available in 3 forms: the X850 Pro, the X850 XT, and the X850 XT Platinum Edition, and was built on the reliable high-performance 130 nm Low-K process.Supercharge 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.
