GeForce GTX 480 vs Geforce GTX 680

Intro

The GeForce GTX 480 features a core clock frequency of 700 MHz and a GDDR5 memory speed of 924 MHz. It also uses a 384-bit memory bus, and makes use of a 40 nm design. It features 480 SPUs, 60 Texture Address Units, and 48 ROPs.

Compare those specifications to the Geforce GTX 680, which has core speeds of 1006 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 1536 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

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

Memory Bandwidth

Theoretically speaking, the Geforce GTX 680 should be 8% quicker 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 quite a bit (approximately 207%) faster with regards to anisotropic filtering 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 high levels of AA is important to you, then the GeForce GTX 480 is the winner, though 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 largest amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total texture units by the core clock 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 per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
