GeForce GTX 960 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which features a clock frequency of 1175 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit bus, and uses a 14 nm design. It is comprised of 1024 SPUs, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce GTX 960		120 Watts
	Difference: 40 Watts (50%)

Memory Bandwidth

In theory, the Radeon RX 560 should be a small bit faster than the GeForce GTX 960 overall. (explain)

Radeon RX 560		114688 MB/sec
GeForce GTX 960		112000 MB/sec
	Difference: 2688 (2%)

Texel Rate

The Radeon RX 560 is a bit (more or less 4%) more effective at texture filtering than the GeForce GTX 960. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 960		72128 Mtexels/sec
	Difference: 3072 (4%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 960 is a better choice, by far. (explain)

GeForce GTX 960		36064 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 17264 (92%)

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 transferred across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core 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 processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
