In terms of overall gaming performance, the graphical capabilities of the AMD Radeon X1800 XL are very slightly better than the Nvidia GeForce 6800 Ultra.

The Radeon X1800 XL was released less than a year after the GeForce 6800 Ultra, and so they are likely to have similar driver support for optimizing performance when running the latest games.

The Radeon X1800 XL and the GeForce 6800 Ultra have the same amount of video memory, but are likely to provide slightly different experiences when displaying game textures at high resolutions.

The Radeon X1800 XL has 28.8 GB/sec greater memory bandwidth than the GeForce 6800 Ultra, which means that the memory performance of the Radeon X1800 XL is slightly better than the GeForce 6800 Ultra.

The Radeon X1800 XL has 16 Shader Processing Units and the GeForce 6800 Ultra has 22. However, the actual shader performance of the Radeon X1800 XL is 5 and the actual shader performance of the GeForce 6800 Ultra is 9. The GeForce 6800 Ultra having 4 better shader performance is not particularly notable, as altogether the Radeon X1800 XL performs better when taking into account other relevant data.

The Radeon X1800 XL requires 70 Watts to run and the GeForce 6800 Ultra requires 124 Watts. The GeForce 6800 Ultra requires 54 Watts more than the Radeon X1800 XL to run. The difference is significant enough that the GeForce 6800 Ultra may have an adverse affect on your yearly electricity bills in comparison to the Radeon X1800 XL.

GPU Mini Review

Mini ReviewRadeon X1800 XL is a performance GPU based on the 90nm variant of the R500 architecture.
It's based on the R520 Core and offers 16 Pixel Shaders, 16 TMUs and 16 ROPs, on a 256-bit of standard GDDR3. The central unit runs at 500MHz and the memory clock operates at up to 500MHz.
Its performance is considerably better than Radeon X1800 GTO thanks to core configuration, as is the power consumption.
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.
The groundbreaking new NVIDIA GeForce 6800 graphics processing units (GPUs) and their revolutionary technologies power worlds where reality and fantasy meet; worlds in which new standards are set for visual realism and quality, performance, and video functionality. The GeForce 6800 GPUs deliver powerful, elegant graphics to drench your senses, immersing you in unparalleled worlds of visual effects for the ultimate PC experience.
