GeForce GTX 470 vs Radeon HD 6850
Intro
The GeForce GTX 470 comes with a clock frequency of 607 MHz and a GDDR5 memory speed of 837 MHz. It also features a 320-bit memory bus, and uses a 40 nm design. It is made up of 448 SPUs, 56 Texture Address Units, and 40 ROPs.Compare those specs to the Radeon HD 6850, which features clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 960 SPUs along with 48 Texture Address Units and 32 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transported over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.

Radeon HD 6850 is better
I have both cards and I can say without a doubt that the GTX470 is noticably faster, as well as being able to handle high resolutions better and being better at antialiasing. I must run most games a whole tier lower for graphics settings on the radeon card (I.e. medium for the 6850, whereas the 470 can handle high for the same game)
