Radeon HD 4550 512MB		25 Watts
GeForce GT 130		75 Watts
	Difference: 50 Watts (200%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 4550 512MB should be 7% quicker than the GeForce GT 130 overall, because of its higher bandwidth. (explain)

Radeon HD 4550 512MB		12800 MB/sec
GeForce GT 130		12000 MB/sec
	Difference: 800 (7%)

Texel Rate

The GeForce GT 130 will be a lot (approximately 150%) more effective at AF than the Radeon HD 4550 512MB. (explain)

GeForce GT 130		12000 Mtexels/sec
Radeon HD 4550 512MB		4800 Mtexels/sec
	Difference: 7200 (150%)

Pixel Rate

The GeForce GT 130 should be much (approximately 233%) more effective at FSAA than the Radeon HD 4550 512MB, and should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GT 130		8000 Mpixels/sec
Radeon HD 4550 512MB		2400 Mpixels/sec
	Difference: 5600 (233%)

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 data (measured in MB per second) that can be transported over the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR 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 worked out by multiplying the total texture units by the core speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
