Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R9 M375 should in theory be quite a bit superior to the Radeon HD 5450 in general. (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 (more or less 681%) better at anisotropic filtering than the Radeon HD 5450. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M375 is superior to the Radeon HD 5450, by a large margin. (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: Bandwidth is the maximum amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 are applied per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
