GeForce GTX 580 vs Radeon RX 470 4GB

Intro

Compare those specs to the Radeon RX 470 4GB, which makes use of a 14 nm design. AMD has set the core frequency at 926 MHz. The GDDR5 memory runs at a speed of 1650 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

GeForce GTX 580		49408 Mtexels/sec
	Difference: 69120 (140%)

Pixel Rate

The GeForce GTX 580 should be a lot (more or less 25%) more effective at AA than the Radeon RX 470 4GB, and will be able to handle higher screen resolutions more effectively. (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 maximum amount of information (measured in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the graphics 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 most pixels the graphics card 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 colour ROPs 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 fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
