Radeon HD 7850 vs Radeon R7 M260

Intro

Compare all of that to the Radeon R7 M260, which features a clock frequency of 715 MHz and a DDR3 memory speed of 1000 MHz. It also makes use of a 64-bit bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 Texture Address Units, and 8 ROPs.

	Difference: 137600 (860%)

Texel Rate

The Radeon HD 7850 is quite a bit (more or less 221%) faster with regards to texture filtering than the Radeon R7 M260. (explain)

Radeon HD 7850		55040 Mtexels/sec
Radeon R7 M260		17160 Mtexels/sec
	Difference: 37880 (221%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon HD 7850 is the winner, and very much so. (explain)

Radeon HD 7850		27520 Mpixels/sec
Radeon R7 M260		5720 Mpixels/sec
	Difference: 21800 (381%)

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 max amount of information (counted in MB per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. 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 also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
