Radeon HD 7750 vs Radeon R7 M260X

Intro

The Radeon HD 7750 has a clock frequency of 800 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 512 SPUs, 32 TAUs, and 16 Raster Operation Units.

Compare those specifications to the Radeon R7 M260X, which comes with GPU core speed of 825 MHz, and 2048 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also is made up of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

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

Texel Rate

The Radeon HD 7750 is quite a bit (about 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 is quite a bit (approximately 94%) better at FSAA than the Radeon R7 M260X, and will be able to handle higher resolutions while still performing well. (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: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once 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 are processed per second. This number is worked out by multiplying the total amount of texture units by the core clock 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
