Radeon HD 6750 1GB		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R9 M370X will be a lot (approximately 23%) more effective at texture filtering than the Radeon HD 6750 1GB. (explain)

Radeon R9 M370X		32000 Mtexels/sec
Radeon HD 6750 1GB		26100 Mtexels/sec
	Difference: 5900 (23%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon R9 M370X is superior to the Radeon HD 6750 1GB, though not by far. (explain)

Radeon R9 M370X		12800 Mpixels/sec
Radeon HD 6750 1GB		11600 Mpixels/sec
	Difference: 1200 (10%)

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 largest amount of data (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core 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 many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
