GeForce 8800 GTS (G92) vs GeForce 8800 Ultra

Intro

The GeForce 8800 GTS (G92) features a GPU clock speed of 650 MHz, and the 512 MB of GDDR3 RAM runs at 970 MHz through a 256-bit bus. It also is comprised of 128 SPUs, 64 Texture Address Units, and 16 ROPs.

Compare those specifications to the GeForce 8800 Ultra, which uses a 90 nm design. nVidia has clocked the core frequency at 612 MHz. The GDDR3 memory works at a frequency of 1080 MHz on this particular card. It features 128 SPUs as well as 64 Texture Address Units and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GTS (G92) 135 Watts
GeForce 8800 Ultra 171 Watts
Difference: 36 Watts (27%)

Memory Bandwidth

The GeForce 8800 Ultra should in theory be quite a bit faster than the GeForce 8800 GTS (G92) in general. (explain)

GeForce 8800 Ultra 103680 MB/sec
GeForce 8800 GTS (G92) 62080 MB/sec
Difference: 41600 (67%)

Texel Rate

The GeForce 8800 GTS (G92) should be a little bit (about 6%) more effective at AF than the GeForce 8800 Ultra. (explain)

GeForce 8800 GTS (G92) 41600 Mtexels/sec
GeForce 8800 Ultra 39168 Mtexels/sec
Difference: 2432 (6%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 8800 Ultra is the winner, by a large margin. (explain)

GeForce 8800 Ultra 14688 Mpixels/sec
GeForce 8800 GTS (G92) 10400 Mpixels/sec
Difference: 4288 (41%)

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 maximum amount of data (measured in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total texture units by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
