Radeon R7 260X vs Radeon R9 M380

Intro

The Radeon R7 260X features a GPU clock speed of 1100 MHz, and the 2048 MB of GDDR5 RAM runs at 1625 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

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

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

Texel Rate

The Radeon R7 260X will be much (about 54%) faster with regards to AF 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 should be a bit (approximately 10%) faster with regards to anti-aliasing than the Radeon R9 M380, and also will be able to handle higher screen resolutions while still performing well. (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: Memory bandwidth is the max amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster 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 can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the video 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 amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
