Radeon R7 250X vs Radeon R7 M260X

Intro

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

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon R7 250X should perform a bit faster than the Radeon R7 M260X in general. (explain)

Radeon R7 250X		72000 MB/sec
Radeon R7 M260X		64000 MB/sec
	Difference: 8000 (13%)

Texel Rate

The Radeon R7 250X is a lot (more or less 102%) more effective at anisotropic filtering than the Radeon R7 M260X. (explain)

Radeon R7 250X		40000 Mtexels/sec
Radeon R7 M260X		19800 Mtexels/sec
	Difference: 20200 (102%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R7 250X is superior to the Radeon R7 M260X, by a large margin. (explain)

Radeon R7 250X		16000 Mpixels/sec
Radeon R7 M260X		6600 Mpixels/sec
	Difference: 9400 (142%)

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 (measured in MB per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
