Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 5750 512MB should theoretically be a small bit superior to the Radeon R9 M370X overall. (explain)

Radeon HD 5750 512MB		73600 MB/sec
Radeon R9 M370X		72000 MB/sec
	Difference: 1600 (2%)

Texel Rate

The Radeon R9 M370X is a lot (about 27%) more effective at AF than the Radeon HD 5750 512MB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 5750 512MB		25200 Mtexels/sec
	Difference: 6800 (27%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M370X is superior to the Radeon HD 5750 512MB, but not by far. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 5750 512MB		11200 Mpixels/sec
	Difference: 1600 (14%)

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 information (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
