GeForce GTX 480 vs GeForce GTX 560

Intro

The GeForce GTX 480 features a GPU clock speed of 700 MHz, and the 1536 MB of GDDR5 RAM runs at 924 MHz through a 384-bit bus. It also is comprised of 480 SPUs, 60 TAUs, and 48 Raster Operation Units.

Compare all that to the GeForce GTX 560, which has core clock speeds of 810 MHz on the GPU, and 1001 MHz on the 1024 MB of GDDR5 memory. It features 336 SPUs as well as 56 TAUs and 32 ROPs.

Memory Bandwidth

In theory, the GeForce GTX 480 should be quite a bit faster than the GeForce GTX 560 overall. (explain)

GeForce GTX 480 177408 MB/sec
GeForce GTX 560 128128 MB/sec
Difference: 49280 (38%)

Texel Rate

The GeForce GTX 560 should be a small bit (more or less 8%) faster with regards to anisotropic filtering than the GeForce GTX 480. (explain)

GeForce GTX 560 45360 Mtexels/sec
GeForce GTX 480 42000 Mtexels/sec
Difference: 3360 (8%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 480 is superior to the GeForce GTX 560, and very much so. (explain)

GeForce GTX 480 33600 Mpixels/sec
GeForce GTX 560 25920 Mpixels/sec
Difference: 7680 (30%)

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 megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

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