GeForce GTX 580 3GB vs Radeon R9 280

Intro

The GeForce GTX 580 3GB features a GPU core speed of 772 MHz, and the 3072 MB of GDDR5 memory is set to run at 1002 MHz through a 384-bit bus. It also is made up of 512 Stream Processors, 64 Texture Address Units, and 48 ROPs.

Compare those specifications to the Radeon R9 280, which has GPU clock speed of 933 MHz, and 3072 MB of GDDR5 memory running at 1250 MHz through a 384-bit bus. It also is made up of 1792 SPUs, 112 Texture Address Units, and 32 Raster Operation Units.

The Radeon R9 280 should be much (approximately 111%) better at texture filtering than the GeForce GTX 580 3GB. (explain)

Radeon R9 280 104496 Mtexels/sec
GeForce GTX 580 3GB 49408 Mtexels/sec
Difference: 55088 (111%)

Pixel Rate

The GeForce GTX 580 3GB is much (more or less 24%) faster with regards to anti-aliasing than the Radeon R9 280, and also should be capable of handling higher screen resolutions better. (explain)

GeForce GTX 580 3GB 37056 Mpixels/sec
Radeon R9 280 29856 Mpixels/sec
Difference: 7200 (24%)

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 megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in one 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 - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
