Radeon HD 5750 512MB vs Radeon R9 M265X

Intro

The Radeon HD 5750 512MB comes with clock speeds of 700 MHz on the GPU, and 1150 MHz on the 512 MB of GDDR5 memory. It features 720(144x5) SPUs as well as 36 Texture Address Units and 16 ROPs.

Compare that to the Radeon R9 M265X, which uses a 28 nm design. AMD has set the core frequency at 575 MHz. The GDDR5 memory works at a speed of 1125 MHz on this specific card. 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 512MB should in theory be a small bit superior to the Radeon R9 M265X overall. (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 bit (about 10%) more effective 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 a high screen resolution is important to you, then the Radeon HD 5750 512MB is the winner, by far. (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 information (counted in MB per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 processed in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs 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 also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
