GeForce GTX 580 3GB vs Radeon RX 480 4GB

Intro

The GeForce GTX 580 3GB comes with clock speeds of 772 MHz on the GPU, and 1002 MHz on the 3072 MB of GDDR5 memory. It features 512 SPUs along with 64 TAUs and 48 ROPs.

Compare those specs to the Radeon RX 480 4GB, which makes use of a 14 nm design. AMD has clocked the core frequency at 1120 MHz. The GDDR5 memory runs at a frequency of 1750 MHz on this card. It features 2304 SPUs along with 144 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 480 4GB 150 Watts
GeForce GTX 580 3GB 244 Watts
Difference: 94 Watts (63%)

Memory Bandwidth

In theory, the Radeon RX 480 4GB should perform just a bit faster than the GeForce GTX 580 3GB in general. (explain)

Radeon RX 480 4GB 229376 MB/sec
GeForce GTX 580 3GB 192384 MB/sec
Difference: 36992 (19%)

Texel Rate

The Radeon RX 480 4GB should be a lot (more or less 226%) more effective at texture filtering than the GeForce GTX 580 3GB. (explain)

Radeon RX 480 4GB 161280 Mtexels/sec
GeForce GTX 580 3GB 49408 Mtexels/sec
Difference: 111872 (226%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 580 3GB is superior to the Radeon RX 480 4GB, not by a very large margin though. (explain)

GeForce GTX 580 3GB 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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported across 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 RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR 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 calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes 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, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
