Radeon HD 5750 1GB vs Radeon R9 M270X

Intro

The Radeon HD 5750 1GB has a GPU core 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 comprised of 720(144x5) SPUs, 36 TAUs, and 16 Raster Operation Units.

Compare all that to the Radeon R9 M270X, which has a core clock speed of 725 MHz and a GDDR5 memory frequency of 1125 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It is comprised of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 5750 1GB should in theory be just a bit superior to the Radeon R9 M270X overall. (explain)

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

Texel Rate

The Radeon R9 M270X is a bit (approximately 15%) faster with regards to anisotropic 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

The Radeon R9 M270X is a bit (about 4%) better at FSAA than the Radeon HD 5750 1GB, and also should be able to handle higher screen resolutions without losing too much performance. (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 maximum amount of data (in units of MB per second) that can be transferred past the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the graphics 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. Pixel rate is worked out by multiplying the number of Render Output Units by the the core 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
