GeForce GTX Titan vs Radeon RX 560

Intro

Compare those specifications to the Radeon RX 560, which has GPU core speed of 1175 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 128-bit bus. It also is made up of 1024 Stream Processors, 64 Texture Address Units, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce GTX Titan		250 Watts
	Difference: 170 Watts (213%)

Memory Bandwidth

In theory, the GeForce GTX Titan will be 151% faster than the Radeon RX 560 in general, due to its higher data rate. (explain)

GeForce GTX Titan		288384 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 173696 (151%)

Texel Rate

The GeForce GTX Titan should be much (about 149%) better at AF than the Radeon RX 560. (explain)

GeForce GTX Titan		187488 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 112288 (149%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX Titan is the winner, by far. (explain)

GeForce GTX Titan		40176 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 21376 (114%)

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 max amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If it uses DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
