GeForce GTX 580 vs Radeon RX 470 4GB

Intro

Compare all that to the Radeon RX 470 4GB, which has GPU clock speed of 926 MHz, and 4096 MB of GDDR5 memory set to run at 1650 MHz through a 256-bit bus. It also is comprised of 2048 SPUs, 128 Texture Address Units, and 32 Raster Operation Units.

Radeon RX 470 4GB		120 Watts
GeForce GTX 580		244 Watts
	Difference: 124 Watts (103%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 470 4GB should be 10% quicker than the GeForce GTX 580 in general, due to its higher bandwidth. (explain)

Radeon RX 470 4GB		211200 MB/sec
GeForce GTX 580		192384 MB/sec
	Difference: 18816 (10%)

Texel Rate

The Radeon RX 470 4GB will be quite a bit (about 140%) more effective at AF than the GeForce GTX 580. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 69120 (140%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 580 is superior to the Radeon RX 470 4GB, by a large margin. (explain)

GeForce GTX 580		37056 Mpixels/sec
Radeon RX 470 4GB		29632 Mpixels/sec
	Difference: 7424 (25%)

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 maximum amount of information (measured in MB per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour 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 output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
