GeForce GTX 660 Ti vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which features a core clock frequency of 1175 MHz and a GDDR5 memory speed of 1750 MHz. It also uses a 128-bit memory bus, and uses a 14 nm design. It features 1024 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce GTX 660 Ti		150 Watts
	Difference: 70 Watts (88%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 660 Ti should theoretically be a lot better than the Radeon RX 560 in general. (explain)

GeForce GTX 660 Ti		144000 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 29312 (26%)

Texel Rate

The GeForce GTX 660 Ti will be a lot (more or less 36%) better at texture filtering than the Radeon RX 560. (explain)

GeForce GTX 660 Ti		102480 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 27280 (36%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 660 Ti is a better choice, but it probably won't make a huge difference. (explain)

GeForce GTX 660 Ti		21960 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 3160 (17%)

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 MB per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 applied in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
