GeForce GTX 480 vs Radeon R9 280X

Intro

The GeForce GTX 480 features clock speeds of 700 MHz on the GPU, and 924 MHz on the 1536 MB of GDDR5 RAM. It features 480 SPUs as well as 60 TAUs and 48 Rasterization Operator Units.

Compare that to the Radeon R9 280X, which makes use of a 28 nm design. AMD has set the core frequency at 850 MHz. The GDDR5 memory runs at a speed of 1500 MHz on this particular model. It features 2048 SPUs as well as 128 Texture Address Units and 32 ROPs.

GeForce GTX 480 177408 MB/sec
Difference: 110592 (62%)

Texel Rate

The Radeon R9 280X is quite a bit (about 159%) faster with regards to anisotropic filtering than the GeForce GTX 480. (explain)

Radeon R9 280X 108800 Mtexels/sec
GeForce GTX 480 42000 Mtexels/sec
Difference: 66800 (159%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 480 is a better choice, and very much so. (explain)

GeForce GTX 480 33600 Mpixels/sec
Radeon R9 280X 27200 Mpixels/sec
Difference: 6400 (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 information (counted in megabytes per second) that can be moved past the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 are applied in one second. This is calculated by multiplying the total number of texture units of the card by the core clock 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 applied per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
