Radeon R7 250 vs Radeon R7 M260X

Intro

The Radeon R7 250 has a GPU clock speed of 1000 MHz, and the 1024 MB of GDDR5 memory is set to run at 1150 MHz through a 128-bit bus. It also features 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Compare those specifications to the Radeon R7 M260X, which has GPU core speed of 825 MHz, and 2048 MB of GDDR5 RAM 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.

The Radeon R7 250 is a lot (approximately 21%) more effective at AF than the Radeon R7 M260X. (explain)

Radeon R7 250 24000 Mtexels/sec
Radeon R7 M260X 19800 Mtexels/sec
Difference: 4200 (21%)

Pixel Rate

The Radeon R7 250 should be much (about 21%) faster with regards to AA than the Radeon R7 M260X, and also will be able to handle higher resolutions more effectively. (explain)

Radeon R7 250 8000 Mpixels/sec
Radeon R7 M260X 6600 Mpixels/sec
Difference: 1400 (21%)

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.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
