GeForce GTX 480 vs Radeon R9 380X

Intro

The GeForce GTX 480 has a clock frequency of 700 MHz and a GDDR5 memory frequency of 924 MHz. It also uses a 384-bit bus, and makes use of a 40 nm design. It features 480 SPUs, 60 TAUs, and 48 ROPs.

Compare all of that to the Radeon R9 380X, which uses a 28 nm design. AMD has set the core speed at 970 MHz. The GDDR5 memory works at a frequency of 1425 MHz on this model. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator Units.

In theory, the Radeon R9 380X should be 3% faster than the GeForce GTX 480 in general, due to its higher data rate. (explain)

Radeon R9 380X 182400 MB/sec
GeForce GTX 480 177408 MB/sec
Difference: 4992 (3%)

Texel Rate

The Radeon R9 380X should be much (about 196%) better at anisotropic filtering than the GeForce GTX 480. (explain)

Radeon R9 380X 124160 Mtexels/sec
GeForce GTX 480 42000 Mtexels/sec
Difference: 82160 (196%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 480 is a better choice, not by a very large margin though. (explain)

GeForce GTX 480 33600 Mpixels/sec
Radeon R9 380X 31040 Mpixels/sec
Difference: 2560 (8%)

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 information (measured in megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. 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 applied in one second. This is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling 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 the graphics card could 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 Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
