Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R5 M330 is 13% quicker than the Radeon HD 5450 in general, due to its higher data rate. (explain)

Radeon R5 M330		14400 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The Radeon R5 M330 will be quite a bit (about 296%) faster with regards to texture filtering than the Radeon HD 5450. (explain)

Radeon R5 M330		20600 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 15400 (296%)

Pixel Rate

The Radeon R5 M330 should be much (more or less 217%) faster with regards to AA than the Radeon HD 5450, and also capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon R5 M330		8240 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 5640 (217%)

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 transferred past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to 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 bandwidth is, the lower the ability to reach the max fill rate.
