Geforce GTX 770 vs Radeon RX 560

Intro

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

Radeon RX 560		80 Watts
Geforce GTX 770		230 Watts
	Difference: 150 Watts (188%)

Memory Bandwidth

In theory, the Geforce GTX 770 will be 96% quicker than the Radeon RX 560 in general, due to its greater data rate. (explain)

Geforce GTX 770		224384 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 109696 (96%)

Texel Rate

The Geforce GTX 770 will be much (approximately 78%) more effective at anisotropic filtering than the Radeon RX 560. (explain)

Geforce GTX 770		133888 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 58688 (78%)

Pixel Rate

The Geforce GTX 770 is a lot (more or less 78%) faster with regards to full screen anti-aliasing than the Radeon RX 560, and also able to handle higher screen resolutions more effectively. (explain)

Geforce GTX 770		33472 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 14672 (78%)

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 max amount of data (counted in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 texture map elements (texels) that can be applied in one second. This number is worked out 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
