GeForce 8800 GTS (G92) vs GeForce GTX 550 Ti

Intro

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

Compare those specs to the GeForce GTX 550 Ti, which has a GPU core clock speed of 900 MHz, and 1024 MB of GDDR5 RAM running at 1026 MHz through a 192-bit bus. It also features 192 Stream Processors, 32 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 550 Ti 116 Watts
GeForce 8800 GTS (G92) 135 Watts
Difference: 19 Watts (16%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 550 Ti is 59% faster than the GeForce 8800 GTS (G92) in general, because of its greater data rate. (explain)

GeForce GTX 550 Ti 98496 MB/sec
GeForce 8800 GTS (G92) 62080 MB/sec
Difference: 36416 (59%)

Texel Rate

The GeForce 8800 GTS (G92) is quite a bit (more or less 44%) better at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

GeForce 8800 GTS (G92) 41600 Mtexels/sec
GeForce GTX 550 Ti 28800 Mtexels/sec
Difference: 12800 (44%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce GTX 550 Ti is a better choice, by a large margin. (explain)

GeForce GTX 550 Ti 21600 Mpixels/sec
GeForce 8800 GTS (G92) 10400 Mpixels/sec
Difference: 11200 (108%)

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: Memory bandwidth is the max amount of information (in units of megabytes per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total number of texture units by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock 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 lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
