GeForce GTX 275		127008 MB/sec
GeForce GTX 260 Core 216		111888 MB/sec
	Difference: 15120 (14%)

Texel Rate

The GeForce GTX 275 is quite a bit (about 22%) faster with regards to texture filtering 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

The GeForce GTX 275 should be a bit (about 10%) faster with regards to full screen anti-aliasing than the GeForce GTX 260 Core 216, and will be capable of handling higher resolutions without losing too much performance. (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: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
