GeForce 8800 GS vs GeForce GTX 480

Intro

The GeForce 8800 GS comes with a GPU core clock speed of 550 MHz, and the 384 MB of GDDR3 memory runs at 800 MHz through a 192-bit bus. It also is made up of 96 SPUs, 48 Texture Address Units, and 12 Raster Operation Units.

Compare all that to the GeForce GTX 480, which makes use of a 40 nm design. nVidia has clocked the core speed at 700 MHz. The GDDR5 RAM works at a frequency of 924 MHz on this model. It features 480 SPUs as well as 60 TAUs and 48 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GS 105 Watts
GeForce GTX 480 250 Watts
Difference: 145 Watts (138%)

Memory Bandwidth

The GeForce GTX 480, in theory, should perform much faster than the GeForce 8800 GS overall. (explain)

GeForce GTX 480 177408 MB/sec
GeForce 8800 GS 38400 MB/sec
Difference: 139008 (362%)

Texel Rate

The GeForce GTX 480 should be much (about 59%) better at AF than the GeForce 8800 GS. (explain)

GeForce GTX 480 42000 Mtexels/sec
GeForce 8800 GS 26400 Mtexels/sec
Difference: 15600 (59%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 480 is the winner, and very much so. (explain)

GeForce GTX 480 33600 Mpixels/sec
GeForce 8800 GS 6600 Mpixels/sec
Difference: 27000 (409%)

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 max amount of information (in units of megabytes per second) that can be transported over the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card 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 processed in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
