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 bus, and makes use of a 28 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Compare all of that to the Radeon R7 M260X, which has core speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 7750 should perform a little bit faster than the Radeon R7 M260X overall. (explain)

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

Texel Rate

The Radeon HD 7750 should be quite a bit (more or less 29%) more effective at 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 will be quite a bit (approximately 94%) faster with regards to AA than the Radeon R7 M260X, and should be able to handle higher 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: Bandwidth is the max amount of information (in units of MB per second) that can be transported past the external memory interface within a second. It's calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher 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 texture map elements (texels) that are applied in one second. This is worked out by multiplying the total number of 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
