As far as performance goes, the Radeon HD 7770 should in theory be much superior to the GeForce GT 210 overall. (explain)

Radeon HD 7770		72000 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 59200 (463%)

Texel Rate

The Radeon HD 7770 will be a lot (approximately 749%) better at AF than the GeForce GT 210. (explain)

Radeon HD 7770		40000 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 35288 (749%)

Pixel Rate

The Radeon HD 7770 will be quite a bit (more or less 579%) better at FSAA than the GeForce GT 210, and also able to handle higher resolutions while still performing well. (explain)

Radeon HD 7770		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: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type memory, it should 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, HDR and higher screen resolutions.

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

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