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

Intro

The GeForce 8800 GT 1GB uses a 65 nm design. nVidia has clocked the core frequency at 600 MHz. The GDDR3 RAM runs at a speed of 900 MHz on this card. It features 112 SPUs as well as 56 Texture Address Units and 16 ROPs.

Compare all that to the GeForce 8800 GTS (G92), which has a core clock speed of 650 MHz and a GDDR3 memory frequency of 970 MHz. It also features a 256-bit memory bus, and makes use of a 65 nm design. It is made up of 128 SPUs, 64 TAUs, and 16 ROPs.

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 (about 24%) faster with regards to texture 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 running with high levels of AA is important to you, then the GeForce 8800 GTS (G92) is the winner, 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 largest amount of data (measured in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum number of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
