Radeon HD 5750 512MB vs Radeon R9 M265X

Intro

The Radeon HD 5750 512MB comes with a clock speed of 700 MHz and a GDDR5 memory frequency of 1150 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It features 720(144x5) SPUs, 36 TAUs, and 16 Raster Operation Units.

Compare that to the Radeon R9 M265X, which has a GPU core clock speed of 575 MHz, and 2048 MB of GDDR5 memory running at 1125 MHz through a 128-bit bus. It also features 640 SPUs, 40 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon HD 5750 512MB is 2% quicker than the Radeon R9 M265X in general, because of its greater data rate. (explain)

Radeon HD 5750 512MB 73600 MB/sec
Radeon R9 M265X 72000 MB/sec
Difference: 1600 (2%)

Texel Rate

The Radeon HD 5750 512MB should be a small bit (more or less 10%) better at texture filtering than the Radeon R9 M265X. (explain)

Radeon HD 5750 512MB 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 512MB is a better choice, and very much so. (explain)

Radeon HD 5750 512MB 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 largest amount of data (counted in MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the card will be at handling 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 the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
