GeForce GTX 260 Core 216		111888 MB/sec
	Difference: 15120 (14%)

Texel Rate

The GeForce GTX 275 will be much (more or less 22%) faster with regards to AF than the GeForce GTX 260 Core 216. (explain)

GeForce GTX 275		50640 Mtexels/sec
GeForce GTX 260 Core 216		41472 Mtexels/sec
	Difference: 9168 (22%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 275 is the winner, but only just. (explain)

GeForce GTX 275		17724 Mpixels/sec
GeForce GTX 260 Core 216		16128 Mpixels/sec
	Difference: 1596 (10%)

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: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster 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 are processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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