GeForce GT 320		25280 MB/sec
	Difference: 46720 (185%)

Texel Rate

The Radeon HD 7750 should be a lot (more or less 98%) faster with regards to AF than the GeForce GT 320. (explain)

Radeon HD 7750		25600 Mtexels/sec
GeForce GT 320		12960 Mtexels/sec
	Difference: 12640 (98%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 7750 is superior to the GeForce GT 320, by far. (explain)

Radeon HD 7750		12800 Mpixels/sec
GeForce GT 320		4320 Mpixels/sec
	Difference: 8480 (196%)

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 largest amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 can be processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 the video card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
