GeForce GT 210		12800 MB/sec
	Difference: 121600 (950%)

Texel Rate

The Radeon HD 6790 is much (approximately 613%) better at AF than the GeForce GT 210. (explain)

Radeon HD 6790		33600 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 28888 (613%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon HD 6790 is a better choice, by far. (explain)

Radeon HD 6790		13440 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 11084 (470%)

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 largest amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
