Radeon HD 5750 1GB vs Radeon R9 M275X

Intro

The Radeon HD 5750 1GB has a GPU core clock speed of 700 MHz, and the 1024 MB of GDDR5 memory is set to run at 1150 MHz through a 128-bit bus. It also is made up of 720(144x5) SPUs, 36 TAUs, and 16 ROPs.

Compare those specifications to the Radeon R9 M275X, which has a core clock frequency of 900 MHz and a GDDR5 memory speed of 1125 MHz. It also makes use of a 128-bit memory bus, and uses a 28 nm design. It features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Memory Bandwidth

As far as performance goes, the Radeon HD 5750 1GB should in theory be just a bit superior to the Radeon R9 M275X overall. (explain)

Radeon HD 5750 1GB 73600 MB/sec
Radeon R9 M275X 72000 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon R9 M275X is a lot (approximately 43%) more effective at AF than the Radeon HD 5750 1GB. (explain)

Radeon R9 M275X 36000 Mtexels/sec
Radeon HD 5750 1GB 25200 Mtexels/sec
Difference: 10800 (43%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R9 M275X is a better choice, and very much so. (explain)

Radeon R9 M275X 14400 Mpixels/sec
Radeon HD 5750 1GB 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 max amount of data (in units of megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
