GeForce GTX 580 vs Radeon RX 470 4GB

Intro

Compare those specifications to the Radeon RX 470 4GB, which makes use of a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 memory runs at a speed of 1650 MHz on this particular model. It features 2048 SPUs as well as 128 Texture Address Units and 32 Rasterization Operator Units.

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

Memory Bandwidth

As far as performance goes, the Radeon RX 470 4GB should in theory be a little bit superior to the GeForce GTX 580 overall. (explain)

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

Texel Rate

The Radeon RX 470 4GB should be much (more or less 140%) faster with regards to texture filtering 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 running with lots of anti-aliasing is important to you, then the GeForce GTX 580 is a better choice, 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: Bandwidth is the max amount of information (measured in megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record 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 - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
