Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 7750 should be 13% faster than the Radeon R7 M260X in general, because of its higher data rate. (explain)

Radeon HD 7750 72000 MB/sec
Radeon R7 M260X 64000 MB/sec
Difference: 8000 (13%)

Texel Rate

The Radeon HD 7750 should be much (more or less 29%) more effective at texture 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 should be much (more or less 94%) better at full screen anti-aliasing than the Radeon R7 M260X, and will be capable of handling higher screen resolutions better. (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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 maximum number of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
