GeForce 8800 GS vs GeForce GTX 550 Ti

Intro

Compare that to the GeForce GTX 550 Ti, which features clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs as well as 32 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 8800 GS		105 Watts
GeForce GTX 550 Ti		116 Watts
	Difference: 11 Watts (10%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 550 Ti should be 157% faster than the GeForce 8800 GS in general, due to its greater data rate. (explain)

GeForce GTX 550 Ti		98496 MB/sec
GeForce 8800 GS		38400 MB/sec
	Difference: 60096 (157%)

Texel Rate

The GeForce GTX 550 Ti will be a little bit (about 9%) more effective at texture filtering than the GeForce 8800 GS. (explain)

GeForce GTX 550 Ti		28800 Mtexels/sec
GeForce 8800 GS		26400 Mtexels/sec
	Difference: 2400 (9%)

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 550 Ti is the winner, by far. (explain)

GeForce GTX 550 Ti		21600 Mpixels/sec
GeForce 8800 GS		6600 Mpixels/sec
	Difference: 15000 (227%)

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.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (measured in megabytes per second) that can be moved over the external memory interface within a second. It is calculated by multiplying the interface 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 4 instead. The higher the memory bandwidth, the faster 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 number of texture map elements (texels) that are processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per 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 worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
