Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon HD 6450 (OEM) 1GB should in theory be much faster than the GeForce GT 210 overall. (explain)

Radeon HD 6450 (OEM) 1GB		28800 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 16000 (125%)

Texel Rate

The Radeon HD 6450 (OEM) 1GB should be quite a bit (more or less 27%) better at anisotropic filtering 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 will be a lot (about 27%) better at anti-aliasing than the GeForce GT 210, and also will be able to handle higher screen resolutions without slowing down too much. (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: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
