Radeon R7 260X vs Radeon R9 M380

Intro

The Radeon R7 260X features core speeds of 1100 MHz on the GPU, and 1625 MHz on the 2048 MB of GDDR5 memory. It features 896 SPUs as well as 56 Texture Address Units and 16 ROPs.

Compare those specifications to the Radeon R9 M380, which comes with clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 RAM. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the Radeon R7 260X should theoretically be a little bit better than the Radeon R9 M380 overall. (explain)

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

Texel Rate

The Radeon R7 260X will be quite a bit (more or less 54%) faster with regards to 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

If running with lots of anti-aliasing is important to you, then the Radeon R7 260X is superior to the Radeon R9 M380, but not by far. (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 maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the graphics 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 maximum number of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs 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 fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
