GeForce GTX 460 2GB 115200 MB/sec
Difference: 19200 (17%)

Texel Rate

The Radeon HD 6870 should be a lot (approximately 33%) faster with regards to texture filtering than the GeForce GTX 460 2GB. (explain)

Radeon HD 6870 50400 Mtexels/sec
GeForce GTX 460 2GB 37800 Mtexels/sec
Difference: 12600 (33%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 6870 is a better choice, and very much so. (explain)

Radeon HD 6870 28800 Mpixels/sec
GeForce GTX 460 2GB 21600 Mpixels/sec
Difference: 7200 (33%)

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: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
