Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M375 is 175% quicker than the Radeon HD 5450 in general, because of its higher data rate. (explain)

Radeon R9 M375		35200 MB/sec
Radeon HD 5450		12800 MB/sec
	Difference: 22400 (175%)

Texel Rate

The Radeon R9 M375 will be a lot (approximately 681%) more effective at texture filtering than the Radeon HD 5450. (explain)

Radeon R9 M375		40600 Mtexels/sec
Radeon HD 5450		5200 Mtexels/sec
	Difference: 35400 (681%)

Pixel Rate

The Radeon R9 M375 is a lot (more or less 525%) more effective at FSAA than the Radeon HD 5450, and will be able to handle higher resolutions while still performing well. (explain)

Radeon R9 M375		16240 Mpixels/sec
Radeon HD 5450		2600 Mpixels/sec
	Difference: 13640 (525%)

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 maximum amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
