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

Texel Rate

The Radeon R9 M370X should be quite a bit (about 27%) faster with regards to 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

The Radeon R9 M370X should be a little bit (more or less 14%) more effective at AA than the Radeon HD 5750 512MB, and will be capable of handling higher screen resolutions without losing too much performance. (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 data (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units 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 one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
