GeForce GTX 460 2GB vs Radeon RX 560

Intro

Compare all that to the Radeon RX 560, which comes with clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 1024 SPUs along with 64 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce GTX 460 2GB		160 Watts
	Difference: 80 Watts (100%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 460 2GB will be 0% faster than the Radeon RX 560 in general, because of its higher bandwidth. (explain)

GeForce GTX 460 2GB		115200 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 512 (0%)

Texel Rate

The Radeon RX 560 will be quite a bit (approximately 99%) faster with regards to AF than the GeForce GTX 460 2GB. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 460 2GB		37800 Mtexels/sec
	Difference: 37400 (99%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 460 2GB is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 460 2GB		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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
