Radeon R7 260X vs Radeon R7 M260X

Intro

Compare all of that to the Radeon R7 M260X, which has GPU core speed of 825 MHz, and 2048 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is made up of 384 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 260X is 63% faster than the Radeon R7 M260X overall, because of its higher data rate. (explain)

Radeon R7 260X		104000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 40000 (63%)

Texel Rate

The Radeon R7 260X is a lot (approximately 211%) more effective at anisotropic filtering than the Radeon R7 M260X. (explain)

Radeon R7 260X		61600 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 41800 (211%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 260X is the winner, by far. (explain)

Radeon R7 260X		17600 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 11000 (167%)

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: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 is calculated by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the card will be at handling 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 that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called 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 bandwidth is, the lower the potential to reach the max fill rate.
