GeForce GTX 480 vs Geforce GTX 680

Intro

The GeForce GTX 480 comes with 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 TAUs and 48 Rasterization Operator Units.

Compare all of that to the Geforce GTX 680, which has GPU core speed of 1006 MHz, and 2048 MB of GDDR5 memory set to run at 1502 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 128 Texture Address Units, and 32 ROPs.

GeForce GTX 480 250 Watts
Difference: 55 Watts (28%)

Memory Bandwidth

Theoretically speaking, the Geforce GTX 680 should be 8% faster than the GeForce GTX 480 in general, because of its higher data rate. (explain)

Geforce GTX 680 192256 MB/sec
GeForce GTX 480 177408 MB/sec
Difference: 14848 (8%)

Texel Rate

The Geforce GTX 680 will be a lot (more or less 207%) more effective at AF than the GeForce GTX 480. (explain)

Geforce GTX 680 128768 Mtexels/sec
GeForce GTX 480 42000 Mtexels/sec
Difference: 86768 (207%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 480 is a better choice, but not by far. (explain)

GeForce GTX 480 33600 Mpixels/sec
Geforce GTX 680 32192 Mpixels/sec
Difference: 1408 (4%)

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 max amount of data (in units of MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher 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 amount of texture map elements (texels) that are processed per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video 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 amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
