Radeon HD 5850 128000 MB/sec
GeForce GTX 460 (OEM) 108800 MB/sec
Difference: 19200 (18%)

Texel Rate

The Radeon HD 5850 is quite a bit (about 43%) faster with regards to anisotropic filtering than the GeForce GTX 460 (OEM). (explain)

Radeon HD 5850 52200 Mtexels/sec
GeForce GTX 460 (OEM) 36400 Mtexels/sec
Difference: 15800 (43%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 5850 is a better choice, but only just. (explain)

Radeon HD 5850 23200 Mpixels/sec
GeForce GTX 460 (OEM) 20800 Mpixels/sec
Difference: 2400 (12%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
