GeForce GTX 580 vs Radeon RX 480 4GB

Intro

The GeForce GTX 580 comes with a core clock speed of 772 MHz and a GDDR5 memory speed of 1002 MHz. It also makes use of a 384-bit bus, and uses a 40 nm design. It is comprised of 512 SPUs, 64 Texture Address Units, and 48 Raster Operation Units.

Compare those specifications to the Radeon RX 480 4GB, which has a core clock speed of 1120 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 256-bit bus, and uses a 14 nm design. It is comprised of 2304 SPUs, 144 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the Radeon RX 480 4GB is 19% quicker than the GeForce GTX 580 in general, because of its greater data rate. (explain)

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

Texel Rate

The Radeon RX 480 4GB is a lot (approximately 226%) better at anisotropic filtering than the GeForce GTX 580. (explain)

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

Pixel Rate

The GeForce GTX 580 is just a bit (more or less 3%) more effective at AA than the Radeon RX 480 4GB, and also should be capable of handling higher resolutions without slowing down too much. (explain)

GeForce GTX 580 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 (measured in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
