GeForce GTX 460 SE vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which comes with a core clock frequency of 1175 MHz and a GDDR5 memory frequency of 1750 MHz. It also makes use of a 128-bit memory bus, and uses a 14 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

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 small bit faster than the GeForce GTX 460 SE in general. (explain)

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

Texel Rate

The Radeon RX 560 is a lot (about 141%) better at texture 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 a high screen 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 maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends 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 max fill rate.
