Radeon R7 250 vs Radeon R7 M260X

Intro

The Radeon R7 250 comes with a core clock frequency of 1000 MHz and a GDDR5 memory speed of 1150 MHz. It also features a 128-bit memory bus, and makes use of a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Compare those specifications to the Radeon R7 M260X, which comes with clock speeds of 825 MHz on the GPU, and 1000 MHz on the 2048 MB of GDDR5 RAM. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R7 250 should theoretically perform a small bit faster than the Radeon R7 M260X in general. (explain)

Radeon R7 250 73600 MB/sec
Radeon R7 M260X 64000 MB/sec
Difference: 9600 (15%)

Texel Rate

The Radeon R7 250 should be quite a bit (approximately 21%) faster with regards to texture filtering than the Radeon R7 M260X. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon R7 250 is superior to the Radeon R7 M260X, by a large margin. (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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
