GeForce GT 210		12800 MB/sec
	Difference: 16000 (125%)

Texel Rate

The Radeon HD 6450 (OEM) 1GB will be a lot (more or less 27%) faster with regards to AF than the GeForce GT 210. (explain)

Radeon HD 6450 (OEM) 1GB		6000 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 1288 (27%)

Pixel Rate

The Radeon HD 6450 (OEM) 1GB is quite a bit (approximately 27%) better at full screen anti-aliasing than the GeForce GT 210, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon HD 6450 (OEM) 1GB		3000 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 644 (27%)

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 maximum amount of information (in units of MB per second) that can be moved past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum 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 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 maximum amount of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
