GeForce 8800 GT 1GB vs GeForce 8800 GTS (G92)

Intro

The GeForce 8800 GT 1GB makes use of a 65 nm design. nVidia has clocked the core speed at 600 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this particular card. It features 112 SPUs as well as 56 TAUs and 16 ROPs.

Compare all of that to the GeForce 8800 GTS (G92), which comes with a GPU core clock speed of 650 MHz, and 512 MB of GDDR3 RAM running at 970 MHz through a 256-bit bus. It also features 128 SPUs, 64 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 1GB 105 Watts
GeForce 8800 GTS (G92) 135 Watts
Difference: 30 Watts (29%)

Memory Bandwidth

In theory, the GeForce 8800 GTS (G92) will be 8% faster than the GeForce 8800 GT 1GB overall, because of its higher data rate. (explain)

GeForce 8800 GTS (G92) 62080 MB/sec
GeForce 8800 GT 1GB 57600 MB/sec
Difference: 4480 (8%)

Texel Rate

The GeForce 8800 GTS (G92) will be much (more or less 24%) more effective at anisotropic filtering than the GeForce 8800 GT 1GB. (explain)

GeForce 8800 GTS (G92) 41600 Mtexels/sec
GeForce 8800 GT 1GB 33600 Mtexels/sec
Difference: 8000 (24%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce 8800 GTS (G92) is a better choice, not by a very large margin though. (explain)

GeForce 8800 GTS (G92) 10400 Mpixels/sec
GeForce 8800 GT 1GB 9600 Mpixels/sec
Difference: 800 (8%)

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 in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's 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 texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 filling the screen with pixels (the image). 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 get to the maximum fill rate.
