Radeon RX 560 vs Radeon RX 570

Intro

Compare all of that to the Radeon RX 570, which features core clock speeds of 1168 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 memory. It features 2048 SPUs along with 128 TAUs and 32 ROPs.

Radeon RX 560		114688 MB/sec
	Difference: 114688 (100%)

Texel Rate

The Radeon RX 570 will be much (more or less 99%) better at anisotropic filtering than the Radeon RX 560. (explain)

Radeon RX 570		149504 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 74304 (99%)

Pixel Rate

The Radeon RX 570 is much (about 99%) faster with regards to FSAA than the Radeon RX 560, and also able to handle higher screen resolutions without slowing down too much. (explain)

Radeon RX 570		37376 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 18576 (99%)

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 (measured in megabytes per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the interface width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the graphics card will be at handling 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 can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
