Radeon R9 M280X vs Radeon R9 M380

Intro

The Radeon R9 M280X uses a 28 nm design. AMD has clocked the core speed at 900 MHz. The GDDR5 memory works at a speed of 1375 MHz on this model. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Compare that to the Radeon R9 M380, which features a clock speed of 1000 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 128-bit bus, and uses a 28 nm design. It is comprised of 640 SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The Radeon R9 M380 should theoretically be a bit faster than the Radeon R9 M280X in general. (explain)

Radeon R9 M380 96000 MB/sec
Radeon R9 M280X 88000 MB/sec
Difference: 8000 (9%)

Texel Rate

The Radeon R9 M280X should be much (more or less 26%) better at texture filtering than the Radeon R9 M380. (explain)

Radeon R9 M280X 50400 Mtexels/sec
Radeon R9 M380 40000 Mtexels/sec
Difference: 10400 (26%)

Pixel Rate

If using a high resolution is important to you, then the Radeon R9 M380 is the winner, though not by far. (explain)

Radeon R9 M380 16000 Mpixels/sec
Radeon R9 M280X 14400 Mpixels/sec
Difference: 1600 (11%)

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 information (measured in megabytes per second) that can be moved over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 amount of texture map elements (texels) that are processed in one second. This number is calculated 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 graphics 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 most 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 worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
