Radeon HD 5750 512MB vs Radeon R9 M280X

Intro

The Radeon HD 5750 512MB comes with core clock speeds of 700 MHz on the GPU, and 1150 MHz on the 512 MB of GDDR5 RAM. It features 720(144x5) SPUs as well as 36 TAUs and 16 ROPs.

Compare all that to the Radeon R9 M280X, which uses a 28 nm design. AMD has clocked the core frequency at 900 MHz. The GDDR5 memory works at a speed of 1375 MHz on this specific model. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

The Radeon R9 M280X should be quite a bit (about 100%) more effective at anisotropic filtering than the Radeon HD 5750 512MB. (explain)

Radeon R9 M280X 50400 Mtexels/sec
Radeon HD 5750 512MB 25200 Mtexels/sec
Difference: 25200 (100%)

Pixel Rate

The Radeon R9 M280X will be much (more or less 29%) more effective at full screen anti-aliasing than the Radeon HD 5750 512MB, and also able to handle higher resolutions better. (explain)

Radeon R9 M280X 14400 Mpixels/sec
Radeon HD 5750 512MB 11200 Mpixels/sec
Difference: 3200 (29%)

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 maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
