Radeon R7 M260 vs Radeon R9 M380

Intro

The Radeon R7 M260 comes with a GPU core speed of 715 MHz, and the 2048 MB of DDR3 RAM is set to run at 1000 MHz through a 64-bit bus. It also features 384 SPUs, 24 TAUs, and 8 Raster Operation Units.

Compare that to the Radeon R9 M380, which has a GPU core clock speed of 1000 MHz, and 4096 MB of GDDR5 memory running at 1500 MHz through a 128-bit bus. It also features 640 Stream Processors, 40 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R9 M380 should be 500% quicker than the Radeon R7 M260 overall, because of its greater data rate. (explain)

Radeon R9 M380 96000 MB/sec
Radeon R7 M260 16000 MB/sec
Difference: 80000 (500%)

Texel Rate

The Radeon R9 M380 should be a lot (more or less 133%) better at texture filtering than the Radeon R7 M260. (explain)

Radeon R9 M380 40000 Mtexels/sec
Radeon R7 M260 17160 Mtexels/sec
Difference: 22840 (133%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon R9 M380 is a better choice, by far. (explain)

Radeon R9 M380 16000 Mpixels/sec
Radeon R7 M260 5720 Mpixels/sec
Difference: 10280 (180%)

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 max amount of data (in units of MB per second) that can be moved 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, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
