GeForce GT 1030		49152 MB/sec
Radeon HD 4550 256MB		12800 MB/sec
	Difference: 36352 (284%)

Texel Rate

The GeForce GT 1030 will be much (more or less 743%) more effective at AF than the Radeon HD 4550 256MB. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon HD 4550 256MB		4800 Mtexels/sec
	Difference: 35680 (743%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GT 1030 is the winner, by far. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon HD 4550 256MB		2400 Mpixels/sec
	Difference: 17840 (743%)

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 data (measured in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. 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 amount of texture map elements (texels) that are applied in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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