	Difference: 48000 (300%)

Texel Rate

The Radeon HD 6750 1GB is much (more or less 454%) faster with regards to anisotropic filtering than the GeForce GT 310. (explain)

Radeon HD 6750 1GB		26100 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 21388 (454%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 6750 1GB is superior to the GeForce GT 310, and very much so. (explain)

Radeon HD 6750 1GB		11600 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 9244 (392%)

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 (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type 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 AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
