Texel Rate

The GeForce GTX 275 will be quite a bit (about 34%) faster with regards to texture filtering than the GeForce GTX 460 2GB. (explain)

GeForce GTX 275		50640 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 12840 (34%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 460 2GB is superior to the GeForce GTX 275, and very much so. (explain)

GeForce GTX 460 2GB		21600 Mpixels/sec
GeForce GTX 275		17724 Mpixels/sec
	Difference: 3876 (22%)

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 data (measured in MB per second) that can be transported past the external memory interface in a 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 DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the 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 amount of pixels the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
