VS

GeForce 8800 GT 512MB vs GeForce 8800 GTS (G92)

Intro

The GeForce 8800 GT 512MB has core speeds of 600 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 112 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Compare that to the GeForce 8800 GTS (G92), which comes with GPU core speed of 650 MHz, and 512 MB of GDDR3 RAM set to run at 970 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GT 512MB 105 Watts
GeForce 8800 GTS (G92) 135 Watts
Difference: 30 Watts (29%)

Memory Bandwidth

Theoretically speaking, the GeForce 8800 GTS (G92) should be 8% quicker than the GeForce 8800 GT 512MB overall, because of its greater data rate. (explain)

GeForce 8800 GTS (G92) 62080 MB/sec
GeForce 8800 GT 512MB 57600 MB/sec
Difference: 4480 (8%)

Texel Rate

The GeForce 8800 GTS (G92) will be much (about 24%) more effective at AF than the GeForce 8800 GT 512MB. (explain)

GeForce 8800 GTS (G92) 41600 Mtexels/sec
GeForce 8800 GT 512MB 33600 Mtexels/sec
Difference: 8000 (24%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 8800 GTS (G92) is the winner, but it probably won't make a huge difference. (explain)

GeForce 8800 GTS (G92) 10400 Mpixels/sec
GeForce 8800 GT 512MB 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 (counted in MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
