Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 260X is 8% faster than the Radeon R9 M380 overall, due to its higher data rate. (explain)

Radeon R7 260X 104000 MB/sec
Radeon R9 M380 96000 MB/sec
Difference: 8000 (8%)

Texel Rate

The Radeon R7 260X will be a lot (approximately 54%) better at texture filtering than the Radeon R9 M380. (explain)

Radeon R7 260X 61600 Mtexels/sec
Radeon R9 M380 40000 Mtexels/sec
Difference: 21600 (54%)

Pixel Rate

The Radeon R7 260X is a small bit (approximately 10%) better at FSAA than the Radeon R9 M380, and also will be able to handle higher screen resolutions more effectively. (explain)

Radeon R7 260X 17600 Mpixels/sec
Radeon R9 M380 16000 Mpixels/sec
Difference: 1600 (10%)

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 (in units of MB per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
