GeForce GTX 460 SE vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which comes with core 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 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce GTX 460 SE		150 Watts
	Difference: 70 Watts (88%)

Memory Bandwidth

The Radeon RX 560 should in theory perform a little bit faster than the GeForce GTX 460 SE overall. (explain)

Radeon RX 560		114688 MB/sec
GeForce GTX 460 SE		108800 MB/sec
	Difference: 5888 (5%)

Texel Rate

The Radeon RX 560 is much (approximately 141%) more effective at anisotropic filtering 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 using lots of anti-aliasing is important to you, then the GeForce GTX 460 SE is superior to the Radeon RX 560, not by a very large margin though. (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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
