GeForce GTX 550 Ti vs Radeon RX 560

Intro

Compare those specs to the Radeon RX 560, which features clock speeds of 1175 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 1024 SPUs as well as 64 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce GTX 550 Ti		116 Watts
	Difference: 36 Watts (45%)

Memory Bandwidth

In theory, the Radeon RX 560 will be 16% faster than the GeForce GTX 550 Ti in general, due to its greater data rate. (explain)

Radeon RX 560		114688 MB/sec
GeForce GTX 550 Ti		98496 MB/sec
	Difference: 16192 (16%)

Texel Rate

The Radeon RX 560 should be a lot (about 161%) more effective at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

Radeon RX 560		75200 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 46400 (161%)

Pixel Rate

The GeForce GTX 550 Ti will be a small bit (approximately 15%) more effective at full screen anti-aliasing than the Radeon RX 560, and also should be able to handle higher resolutions better. (explain)

GeForce GTX 550 Ti		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: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the bus width by its memory speed. If the card has DDR RAM, it must 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 higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
