GeForce GTX 580 3GB vs Radeon RX 570

Intro

Compare those specs to the Radeon RX 570, which has GPU core speed of 1168 MHz, and 4096 MB of GDDR5 RAM set to run at 1750 MHz through a 256-bit bus. It also is made up of 2048 SPUs, 128 Texture Address Units, and 32 ROPs.

Radeon RX 570		150 Watts
GeForce GTX 580 3GB		244 Watts
	Difference: 94 Watts (63%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 570 should be 19% faster than the GeForce GTX 580 3GB in general, because of its greater data rate. (explain)

Radeon RX 570		229376 MB/sec
GeForce GTX 580 3GB		192384 MB/sec
	Difference: 36992 (19%)

Texel Rate

The Radeon RX 570 will be quite a bit (more or less 203%) better at anisotropic filtering than the GeForce GTX 580 3GB. (explain)

Radeon RX 570		149504 Mtexels/sec
GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 100096 (203%)

Pixel Rate

The Radeon RX 570 will be a small bit (about 1%) faster with regards to anti-aliasing than the GeForce GTX 580 3GB, and also able to handle higher screen resolutions better. (explain)

Radeon RX 570		37376 Mpixels/sec
GeForce GTX 580 3GB		37056 Mpixels/sec
	Difference: 320 (1%)

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 largest amount of information (measured in MB per second) that can be transported over the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
