GeForce GTX 580 3GB vs Radeon R9 380X

Intro

The GeForce GTX 580 3GB makes use of a 40 nm design. nVidia has clocked the core speed at 772 MHz. The GDDR5 RAM works at a frequency of 1002 MHz on this model. It features 512 SPUs along with 64 TAUs and 48 ROPs.

Compare that to the Radeon R9 380X, which has a clock frequency of 970 MHz and a GDDR5 memory speed of 1425 MHz. It also uses a 256-bit bus, and uses a 28 nm design. It features 2048 SPUs, 128 TAUs, and 32 Raster Operation Units.

Radeon R9 380X 182400 MB/sec
Difference: 9984 (5%)

Texel Rate

The Radeon R9 380X will be a lot (more or less 151%) better at anisotropic filtering than the GeForce GTX 580 3GB. (explain)

Radeon R9 380X 124160 Mtexels/sec
GeForce GTX 580 3GB 49408 Mtexels/sec
Difference: 74752 (151%)

Pixel Rate

The GeForce GTX 580 3GB should be a little bit (about 19%) more effective at AA than the Radeon R9 380X, and also should be able to handle higher screen resolutions more effectively. (explain)

GeForce GTX 580 3GB 37056 Mpixels/sec
Radeon R9 380X 31040 Mpixels/sec
Difference: 6016 (19%)

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 maximum amount of data (counted in MB per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better 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 applied in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
