GeForce GTX 480 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which features core clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs as well as 64 Texture Address Units and 16 ROPs.

Memory Bandwidth

In theory, the GeForce GTX 480 is 55% quicker than the Radeon RX 560 in general, due to its greater data rate. (explain)

GeForce GTX 480		177408 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 62720 (55%)

Texel Rate

The Radeon RX 560 will be quite a bit (more or less 79%) better at anisotropic filtering than the GeForce GTX 480. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 480		42000 Mtexels/sec
	Difference: 33200 (79%)

Pixel Rate

The GeForce GTX 480 will be much (about 79%) better at FSAA than the Radeon RX 560, and also capable of handling higher resolutions while still performing well. (explain)

GeForce GTX 480		33600 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 14800 (79%)

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: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units by the core clock 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 a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
