Radeon HD 5750 1GB vs Radeon R7 M260X

Intro

Compare those specs to the Radeon R7 M260X, which comes with a clock frequency of 825 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Radeon R7 M260X		64000 MB/sec
	Difference: 9600 (15%)

Texel Rate

The Radeon HD 5750 1GB is much (about 27%) more effective at anisotropic filtering than the Radeon R7 M260X. (explain)

Radeon HD 5750 1GB		25200 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 5400 (27%)

Pixel Rate

The Radeon HD 5750 1GB will be much (more or less 70%) better at full screen anti-aliasing than the Radeon R7 M260X, and also should be able to handle higher screen resolutions while still performing well. (explain)

Radeon HD 5750 1GB		11200 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 4600 (70%)

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.

Price Comparison

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
