Radeon HD 5750 1GB vs Radeon R9 M265X

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 those specifications to the Radeon R9 M265X, which features core speeds of 575 MHz on the GPU, and 1125 MHz on the 2048 MB of GDDR5 RAM. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon HD 5750 1GB should theoretically be a bit better than the Radeon R9 M265X in general. (explain)

Radeon HD 5750 1GB 73600 MB/sec
Radeon R9 M265X 72000 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon HD 5750 1GB will be a little bit (about 10%) more effective at anisotropic filtering than the Radeon R9 M265X. (explain)

Radeon HD 5750 1GB 25200 Mtexels/sec
Radeon R9 M265X 23000 Mtexels/sec
Difference: 2200 (10%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 5750 1GB is a better choice, by far. (explain)

Radeon HD 5750 1GB 11200 Mpixels/sec
Radeon R9 M265X 9200 Mpixels/sec
Difference: 2000 (22%)

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 megabytes per second) that can be transferred over the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
