Radeon HD 7750 vs Radeon R7 M260X

Intro

Compare that to the Radeon R7 M260X, which has GPU clock speed of 825 MHz, and 2048 MB of GDDR5 memory set to run at 1000 MHz through a 128-bit bus. It also features 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 7750 should theoretically perform a small bit faster than the Radeon R7 M260X in general. (explain)

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

Texel Rate

The Radeon HD 7750 is quite a bit (approximately 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

If running with lots of anti-aliasing is important to you, then the Radeon HD 7750 is a better choice, and very much so. (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: Bandwidth is the maximum amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the 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 clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
