GeForce GTX 550 Ti		98496 MB/sec
	Difference: 10304 (10%)

Texel Rate

The GeForce GTX 460 SE will be just a bit (about 8%) faster with regards to anisotropic filtering than the GeForce GTX 550 Ti. (explain)

GeForce GTX 460 SE		31200 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 2400 (8%)

Pixel Rate

The GeForce GTX 550 Ti is a little bit (more or less 4%) faster with regards to full screen anti-aliasing than the GeForce GTX 460 SE, and will be capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
GeForce GTX 460 SE		20800 Mpixels/sec
	Difference: 800 (4%)

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 moved past the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. In the case of 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling 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 that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
