Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 M360 should in theory be much superior to the Radeon HD 5450 overall. (explain)

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

Texel Rate

The Radeon R7 M360 will be a lot (more or less 419%) faster with regards to AF 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 quite a bit (about 246%) better at AA than the Radeon HD 5450, and also should be able to handle higher screen resolutions without slowing down too much. (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 (in units of megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 number of texture map elements (texels) that are processed per second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
