Radeon HD 5750 512MB vs Radeon R9 M270X

Intro

The Radeon HD 5750 512MB has a GPU core clock speed of 700 MHz, and the 512 MB of GDDR5 RAM is set to run at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) Stream Processors, 36 TAUs, and 16 ROPs.

Compare that to the Radeon R9 M270X, which makes use of a 28 nm design. AMD has set the core frequency at 725 MHz. The GDDR5 RAM runs at a frequency of 1125 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 Rasterization Operator Units.

Radeon R9 M270X 72000 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon R9 M270X should be just a bit (about 15%) more effective at texture filtering than the Radeon HD 5750 512MB. (explain)

Radeon R9 M270X 29000 Mtexels/sec
Radeon HD 5750 512MB 25200 Mtexels/sec
Difference: 3800 (15%)

Pixel Rate

The Radeon R9 M270X should be a little bit (about 4%) faster with regards to FSAA than the Radeon HD 5750 512MB, and will be capable of handling higher resolutions better. (explain)

Radeon R9 M270X 11600 Mpixels/sec
Radeon HD 5750 512MB 11200 Mpixels/sec
Difference: 400 (4%)

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 (measured in MB per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. 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 is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
