Radeon HD 5750 1GB vs Radeon R9 M265X

Intro

The Radeon HD 5750 1GB makes use of a 40 nm design. AMD has clocked the core frequency at 700 MHz. The GDDR5 memory runs at a speed of 1150 MHz on this model. It features 720(144x5) SPUs along with 36 Texture Address Units and 16 Rasterization Operator Units.

Compare those specifications to the Radeon R9 M265X, which comes with 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

The Radeon HD 5750 1GB, in theory, should perform a small bit faster 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 is a small bit (approximately 10%) more effective at texture 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

The Radeon HD 5750 1GB should be quite a bit (about 22%) faster with regards to anti-aliasing than the Radeon R9 M265X, and should be capable of handling higher screen resolutions more effectively. (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 maximum amount of information (counted in MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher 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 chip can possibly write to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
