GeForce 8800 GT 1GB vs GeForce GTX 480

Intro

The GeForce 8800 GT 1GB has clock speeds of 600 MHz on the GPU, and 900 MHz on the 1024 MB of GDDR3 memory. It features 112 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.

Compare those specifications to the GeForce GTX 480, which uses a 40 nm design. nVidia has clocked the core frequency at 700 MHz. The GDDR5 RAM works at a frequency of 924 MHz on this card. It features 480 SPUs as well as 60 Texture Address Units and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB 105 Watts
GeForce GTX 480 250 Watts
Difference: 145 Watts (138%)

Memory Bandwidth

The GeForce GTX 480 should in theory perform quite a bit faster than the GeForce 8800 GT 1GB in general. (explain)

GeForce GTX 480 177408 MB/sec
GeForce 8800 GT 1GB 57600 MB/sec
Difference: 119808 (208%)

Texel Rate

The GeForce GTX 480 will be a lot (about 25%) more effective at AF than the GeForce 8800 GT 1GB. (explain)

GeForce GTX 480 42000 Mtexels/sec
GeForce 8800 GT 1GB 33600 Mtexels/sec
Difference: 8400 (25%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 480 is a better choice, by far. (explain)

GeForce GTX 480 33600 Mpixels/sec
GeForce 8800 GT 1GB 9600 Mpixels/sec
Difference: 24000 (250%)

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 information (counted in MB per second) that can be moved over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
