GeForce GTX 460 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which comes with core clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 1024 SPUs along with 64 TAUs 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

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

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

Texel Rate

The Radeon RX 560 will be quite a bit (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 using a high resolution is important to you, then the Radeon RX 560 is the winner, but 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: Bandwidth is the maximum amount of information (counted in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
