The Radeon R5 M330 is quite a bit (approximately 329%) more effective at texture filtering than the Radeon HD 4550 512MB. (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon HD 4550 512MB		4800 Mtexels/sec
	Difference: 15800 (329%)

Pixel Rate

The Radeon R5 M330 is a lot (more or less 243%) better at FSAA than the Radeon HD 4550 512MB, and will be able to handle higher resolutions while still performing well. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon HD 4550 512MB		2400 Mpixels/sec
	Difference: 5840 (243%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
