Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon R7 M360 will be 25% quicker than the Radeon HD 5450 in general, because of its higher data rate. (explain)

Radeon R7 M360		16000 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 3200 (25%)

Texel Rate

The Radeon R7 M360 will be much (about 419%) faster with regards to texture filtering than the Radeon HD 5450. (explain)

Radeon R7 M360		27000 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 21800 (419%)

Pixel Rate

The Radeon R7 M360 is a lot (approximately 246%) better at AA than the Radeon HD 5450, and also will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon R7 M360		9000 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 6400 (246%)

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 largest amount of data (counted in MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

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