Radeon HD 5670 vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which comes with a GPU core clock speed of 715 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon HD 5670 should be much faster than the Radeon R7 M260 in general. (explain)

Radeon HD 5670		64000 MB/sec
Radeon R7 M260		16000 MB/sec
	Difference: 48000 (300%)

Texel Rate

The Radeon R7 M260 is a little bit (about 11%) more effective at anisotropic filtering than the Radeon HD 5670. (explain)

Radeon R7 M260		17160 Mtexels/sec
Radeon HD 5670		15500 Mtexels/sec
	Difference: 1660 (11%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5670 is the winner, though not by far. (explain)

Radeon HD 5670		6200 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 480 (8%)

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.

Specifications

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface within a second. The number is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
