Radeon HD 7870 vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which uses a 28 nm design. AMD has clocked the core speed at 825 MHz. The GDDR5 RAM runs at a speed of 1000 MHz on this specific model. It features 384 SPUs along with 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon HD 7870 should in theory be much faster than the Radeon R7 M260X overall. (explain)

Radeon HD 7870		153600 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 89600 (140%)

Texel Rate

The Radeon HD 7870 will be a lot (about 304%) better at AF than the Radeon R7 M260X. (explain)

Radeon HD 7870		80000 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 60200 (304%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon HD 7870 is a better choice, by a large margin. (explain)

Radeon HD 7870		32000 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 25400 (385%)

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 largest amount of information (measured in MB per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. 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 lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
