GeForce GTX 460 vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which has 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 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Radeon RX 560 is 33% quicker than the GeForce GTX 460 overall, due to its higher bandwidth. (explain)

Radeon RX 560		114688 MB/sec
GeForce GTX 460		86400 MB/sec
	Difference: 28288 (33%)

Texel Rate

The Radeon RX 560 should be much (about 99%) faster with regards to texture filtering than the GeForce GTX 460. (explain)

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

Pixel Rate

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

Radeon RX 560		18800 Mpixels/sec
GeForce GTX 460		16200 Mpixels/sec
	Difference: 2600 (16%)

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 information (counted in megabytes per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
