GeForce GTX 460 1GB vs Radeon RX 560

Intro

Compare all that to the Radeon RX 560, which makes use of a 14 nm design. AMD has clocked the core frequency at 1175 MHz. The GDDR5 memory works at a speed of 1750 MHz on this specific card. It features 1024 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Texel Rate

The Radeon RX 560 is a lot (approximately 99%) better at AF than the GeForce GTX 460 1GB. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 460 1GB		37800 Mtexels/sec
	Difference: 37400 (99%)

Pixel Rate

The GeForce GTX 460 1GB will be a little bit (more or less 15%) more effective at anti-aliasing than the Radeon RX 560, and also will be capable of handling higher screen resolutions more effectively. (explain)

GeForce GTX 460 1GB		21600 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 2800 (15%)

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 (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record 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 rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
