GeForce GTX 560 128128 MB/sec
Difference: 31872 (25%)

Texel Rate

The Radeon R9 M390X is quite a bit (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 using high levels of AA is important to you, then the GeForce GTX 560 is a better choice, though not by far. (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 largest amount of data (measured in MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at 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 the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
