GeForce GTX 580 3GB vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which makes use of a 14 nm design. AMD has set the core frequency at 926 MHz. The GDDR5 RAM runs at a speed of 1650 MHz on this model. It features 2048 SPUs along with 128 Texture Address Units and 32 ROPs.

GeForce GTX 580 3GB		49408 Mtexels/sec
	Difference: 69120 (140%)

Pixel Rate

The GeForce GTX 580 3GB should be much (more or less 25%) more effective at full screen anti-aliasing than the Radeon RX 470, and also should be able to handle higher screen resolutions better. (explain)

GeForce GTX 580 3GB		37056 Mpixels/sec
Radeon RX 470		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 largest amount of data (measured in megabytes per second) that can be transferred past the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the 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 can be applied in one second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units 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 many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
