Radeon HD 5750 1GB vs Radeon R9 M270X

Intro

The Radeon HD 5750 1GB comes with a GPU core speed of 700 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) SPUs, 36 Texture Address Units, and 16 Raster Operation Units.

Compare those specifications to the Radeon R9 M270X, which uses a 28 nm design. AMD has clocked the core frequency at 725 MHz. The GDDR5 RAM is set to run at a frequency of 1125 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon HD 5750 1GB should in theory be just a bit better than the Radeon R9 M270X in general. (explain)

Radeon HD 5750 1GB 73600 MB/sec
Radeon R9 M270X 72000 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon R9 M270X is just a bit (more or less 15%) more effective at texture filtering than the Radeon HD 5750 1GB. (explain)

Radeon R9 M270X 29000 Mtexels/sec
Radeon HD 5750 1GB 25200 Mtexels/sec
Difference: 3800 (15%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R9 M270X is superior to the Radeon HD 5750 1GB, but it probably won't make a huge difference. (explain)

Radeon R9 M270X 11600 Mpixels/sec
Radeon HD 5750 1GB 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 information (measured in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, 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 maximum number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
