GeForce GTX 275		127008 MB/sec
	Difference: 6912 (5%)

Texel Rate

The GeForce GTX 275 is quite a bit (more or less 49%) faster with regards to anisotropic filtering than the GeForce GTX 470. (explain)

GeForce GTX 275		50640 Mtexels/sec
GeForce GTX 470		33992 Mtexels/sec
	Difference: 16648 (49%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 470 is superior to the GeForce GTX 275, and very much so. (explain)

GeForce GTX 470		24280 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 6556 (37%)

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.

Specifications

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

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