GeForce 8800 GS vs GeForce GTX 480

Intro

The GeForce 8800 GS has core clock speeds of 550 MHz on the GPU, and 800 MHz on the 384 MB of GDDR3 memory. It features 96 SPUs along with 48 TAUs and 12 Rasterization Operator Units.

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

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

Theoretically speaking, the GeForce GTX 480 will be 362% faster than the GeForce 8800 GS overall, due to its higher data rate. (explain)

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

Texel Rate

The GeForce GTX 480 should be quite a bit (about 59%) better at texture filtering than the GeForce 8800 GS. (explain)

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

Pixel Rate

The GeForce GTX 480 is much (more or less 409%) better at anti-aliasing than the GeForce 8800 GS, and also capable of handling higher screen resolutions without losing too much performance. (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: Bandwidth is the largest amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 most pixels the graphics card could possibly record to its local memory per 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 - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
