Radeon R7 M260X		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon HD 7750 will be quite a bit (more or less 29%) faster with regards to anisotropic filtering than the Radeon R7 M260X. (explain)

Radeon HD 7750		25600 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 5800 (29%)

Pixel Rate

The Radeon HD 7750 is quite a bit (about 94%) better at FSAA than the Radeon R7 M260X, and also will be capable of handling higher resolutions without slowing down too much. (explain)

Radeon HD 7750		12800 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 6200 (94%)

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 (measured in MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 applied in one second. This figure is calculated 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 video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
