Radeon R9 M375X		72000 MB/sec
	Difference: 1600 (2%)

Texel Rate

The Radeon R9 M375X is a lot (more or less 61%) more effective at AF than the Radeon HD 5750 1GB. (explain)

Radeon R9 M375X		40600 Mtexels/sec
Radeon HD 5750 1GB		25200 Mtexels/sec
	Difference: 15400 (61%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon R9 M375X is superior to the Radeon HD 5750 1GB, and very much so. (explain)

Radeon R9 M375X		16240 Mpixels/sec
Radeon HD 5750 1GB		11200 Mpixels/sec
	Difference: 5040 (45%)

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 max amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of 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 anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
