Radeon R7 250 vs Radeon R7 M260X

Intro

The Radeon R7 250 comes with core clock speeds of 1000 MHz on the GPU, and 1150 MHz on the 1024 MB of GDDR5 memory. It features 384 SPUs along with 24 TAUs and 8 ROPs.

Compare all that to the Radeon R7 M260X, which makes use of a 28 nm design. AMD has set the core frequency at 825 MHz. The GDDR5 memory works at a speed of 1000 MHz on this card. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon R7 250 should in theory be a bit better than the Radeon R7 M260X overall. (explain)

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

Texel Rate

The Radeon R7 250 should be a lot (approximately 21%) better 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 quite a bit (more or less 21%) better at anti-aliasing than the Radeon R7 M260X, and also should be capable of handling higher screen 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 max amount of data (measured in MB per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 number of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
