Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M370X should be 463% faster than the Radeon HD 4550 512MB in general, due to its higher bandwidth. (explain)

Radeon R9 M370X		72000 MB/sec
Radeon HD 4550 512MB		12800 MB/sec
	Difference: 59200 (463%)

Texel Rate

The Radeon R9 M370X should be much (approximately 567%) better at texture filtering than the Radeon HD 4550 512MB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 4550 512MB		4800 Mtexels/sec
	Difference: 27200 (567%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M370X is a better choice, by a large margin. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 4550 512MB		2400 Mpixels/sec
	Difference: 10400 (433%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better 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 figure 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 graphics 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 maximum number of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
