GeForce GT 1030		49152 MB/sec
Radeon HD 4550 512MB		12800 MB/sec
	Difference: 36352 (284%)

Texel Rate

The GeForce GT 1030 will be quite a bit (about 743%) more effective at texture filtering than the Radeon HD 4550 512MB. (explain)

GeForce GT 1030		40480 Mtexels/sec
Radeon HD 4550 512MB		4800 Mtexels/sec
	Difference: 35680 (743%)

Pixel Rate

The GeForce GT 1030 is a lot (more or less 743%) more effective at full screen anti-aliasing than the Radeon HD 4550 512MB, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GT 1030		20240 Mpixels/sec
Radeon HD 4550 512MB		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 information (counted in megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, 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 number of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of 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.
