GeForce GTX 480 vs GeForce GTX 580

Intro

The GeForce GTX 480 has core clock speeds of 700 MHz on the GPU, and 924 MHz on the 1536 MB of GDDR5 memory. It features 480 SPUs along with 60 Texture Address Units and 48 Rasterization Operator Units.

Compare that to the GeForce GTX 580, which comes with clock speeds of 772 MHz on the GPU, and 1002 MHz on the 1536 MB of GDDR5 RAM. It features 512 SPUs along with 64 Texture Address Units and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 580 244 Watts
GeForce GTX 480 250 Watts
Difference: 6 Watts (2%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 580 should be 8% faster than the GeForce GTX 480 in general, due to its higher bandwidth. (explain)

GeForce GTX 580 192384 MB/sec
GeForce GTX 480 177408 MB/sec
Difference: 14976 (8%)

Texel Rate

The GeForce GTX 580 is a bit (about 18%) more effective at AF than the GeForce GTX 480. (explain)

GeForce GTX 580 49408 Mtexels/sec
GeForce GTX 480 42000 Mtexels/sec
Difference: 7408 (18%)

Pixel Rate

The GeForce GTX 580 will be just a bit (about 10%) faster with regards to full screen anti-aliasing than the GeForce GTX 480, and also able to handle higher screen resolutions better. (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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transported past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
