Geforce GTX 780 vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which has GPU core speed of 1175 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is made up of 1024 Stream Processors, 64 TAUs, and 16 Raster Operation Units.

Radeon RX 560		75200 Mtexels/sec
	Difference: 90496 (120%)

Pixel Rate

If using a high screen resolution is important to you, then the Geforce GTX 780 is a better choice, by a large margin. (explain)

Geforce GTX 780		41424 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 22624 (120%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
