GeForce GT 210		31 Watts
Radeon HD 7790		85 Watts
	Difference: 54 Watts (174%)

Memory Bandwidth

In theory, the Radeon HD 7790 is 650% faster than the GeForce GT 210 in general, because of its greater data rate. (explain)

Radeon HD 7790		96000 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 83200 (650%)

Texel Rate

The Radeon HD 7790 will be a lot (about 1088%) faster with regards to AF than the GeForce GT 210. (explain)

Radeon HD 7790		56000 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 51288 (1088%)

Pixel Rate

The Radeon HD 7790 is a lot (about 579%) more effective at AA than the GeForce GT 210, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon HD 7790		16000 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 13644 (579%)

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 information (measured in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
