GeForce GTX 560 vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which features a core clock speed of 1175 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit memory bus, and makes use of a 14 nm design. It features 1024 SPUs, 64 TAUs, and 16 ROPs.

The Radeon RX 560 is a lot (more or less 66%) better at anisotropic filtering than the GeForce GTX 560. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 29840 (66%)

Pixel Rate

The GeForce GTX 560 will be a lot (approximately 38%) more effective at full screen anti-aliasing than the Radeon RX 560, and will be able to handle higher resolutions better. (explain)

GeForce GTX 560		25920 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 7120 (38%)

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 (measured in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the card's 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 is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
