GeForce GTX 580 vs Radeon RX 480 4GB

Intro

Compare those specs to the Radeon RX 480 4GB, which comes with GPU clock speed of 1120 MHz, and 4096 MB of GDDR5 RAM running at 1750 MHz through a 256-bit bus. It also is made up of 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

GeForce GTX 580		192384 MB/sec
	Difference: 36992 (19%)

Texel Rate

The Radeon RX 480 4GB will be quite a bit (approximately 226%) better at anisotropic filtering than the GeForce GTX 580. (explain)

Radeon RX 480 4GB		161280 Mtexels/sec
GeForce GTX 580		49408 Mtexels/sec
	Difference: 111872 (226%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 580 is the winner, though not by far. (explain)

GeForce GTX 580		37056 Mpixels/sec
Radeon RX 480 4GB		35840 Mpixels/sec
	Difference: 1216 (3%)

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 largest amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better 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 number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core 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 is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
