GeForce GTX 580 vs Radeon RX 470

Intro

The GeForce GTX 580 has a clock frequency of 772 MHz and a GDDR5 memory speed of 1002 MHz. It also features a 384-bit memory bus, and uses a 40 nm design. It is made up of 512 SPUs, 64 TAUs, and 48 Raster Operation Units.

Compare those specifications to the Radeon RX 470, which features GPU core speed of 926 MHz, and 8192 MB of GDDR5 memory running at 1650 MHz through a 256-bit bus. It also features 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

GeForce GTX 580 192384 MB/sec
Difference: 18816 (10%)

Texel Rate

The Radeon RX 470 should be much (about 140%) better at texture filtering than the GeForce GTX 580. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 580 is a better choice, by far. (explain)

GeForce GTX 580 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.

Memory Bandwidth: Bandwidth is the max amount of information (in units of megabytes per second) that can be transported across the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the 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 called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
