Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R5 M330 should be 13% quicker than the Radeon HD 4550 256MB in general, because of its greater data rate. (explain)

Radeon R5 M330		14400 MB/sec
Radeon HD 4550 256MB		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 is quite a bit (more or less 329%) better at AF than the Radeon HD 4550 256MB. (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon HD 4550 256MB		4800 Mtexels/sec
	Difference: 15800 (329%)

Pixel Rate

The Radeon R5 M330 will be a lot (approximately 243%) faster with regards to AA than the Radeon HD 4550 256MB, and also will be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon HD 4550 256MB		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.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

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