Radeon R9 M370X		72000 MB/sec
	Difference: 1600 (2%)

Texel Rate

The Radeon R9 M370X should be a lot (more or less 27%) more effective at texture filtering 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

The Radeon R9 M370X will be a little bit (approximately 14%) better at AA than the Radeon HD 5750 512MB, and will be capable of handling higher screen resolutions better. (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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that 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 Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
