GeForce GTX 560 vs Radeon R9 M390X

Intro

The GeForce GTX 560 comes with core speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs along with 56 Texture Address Units and 32 ROPs.

Compare all that to the Radeon R9 M390X, which features a clock frequency of 723 MHz and a GDDR5 memory speed of 1250 MHz. It also features a 256-bit bus, and makes use of a 28 nm design. It is comprised of 2048 SPUs, 128 TAUs, and 32 ROPs.

In theory, the Radeon R9 M390X will be 25% faster than the GeForce GTX 560 in general, due to its greater data rate. (explain)

Radeon R9 M390X 160000 MB/sec
GeForce GTX 560 128128 MB/sec
Difference: 31872 (25%)

Texel Rate

The Radeon R9 M390X is much (approximately 104%) better at texture filtering than the GeForce GTX 560. (explain)

Radeon R9 M390X 92544 Mtexels/sec
GeForce GTX 560 45360 Mtexels/sec
Difference: 47184 (104%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 560 is the winner, not by a very large margin though. (explain)

GeForce GTX 560 25920 Mpixels/sec
Radeon R9 M390X 23136 Mpixels/sec
Difference: 2784 (12%)

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 maximum amount of information (measured in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
