GeForce GTX 460 SE vs Radeon RX 560

Intro

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

GeForce GTX 460 SE		108800 MB/sec
	Difference: 5888 (5%)

Texel Rate

The Radeon RX 560 should be quite a bit (more or less 141%) better at AF than the GeForce GTX 460 SE. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 460 SE		31200 Mtexels/sec
	Difference: 44000 (141%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 460 SE is superior to the Radeon RX 560, though not by far. (explain)

GeForce GTX 460 SE		20800 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 2000 (11%)

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 max amount of information (counted in MB per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
