GeForce GTX 480 vs GeForce GTX 580

Intro

The GeForce GTX 480 has core speeds of 700 MHz on the GPU, and 924 MHz on the 1536 MB of GDDR5 memory. It features 480 SPUs as well as 60 TAUs and 48 ROPs.

Compare that to the GeForce GTX 580, which comes with a core clock frequency of 772 MHz and a GDDR5 memory speed of 1002 MHz. It also features a 384-bit bus, and makes use of a 40 nm design. It features 512 SPUs, 64 TAUs, and 48 Raster Operation Units.

GeForce GTX 480 42000 Mtexels/sec
Difference: 7408 (18%)

Pixel Rate

The GeForce GTX 580 will be a small bit (more or less 10%) better at AA than the GeForce GTX 480, and able to handle higher resolutions without slowing down too much. (explain)

GeForce GTX 580 37056 Mpixels/sec
GeForce GTX 480 33600 Mpixels/sec
Difference: 3456 (10%)

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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka 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 get to the maximum fill rate.
