GeForce GTX 480 vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which has a clock speed of 1175 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit memory bus, and makes use of a 14 nm design. It is comprised of 1024 SPUs, 64 TAUs, and 16 Raster Operation Units.

The Radeon RX 560 should be quite a bit (more or less 79%) more effective at AF 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 is quite a bit (approximately 79%) better at FSAA than the Radeon RX 560, and will be capable of handling higher screen resolutions more effectively. (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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
