GeForce 8800 GS vs GeForce GTX 550 Ti

Intro

Compare all of that to the GeForce GTX 550 Ti, which makes use of a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 memory is set to run at a speed of 1026 MHz on this model. It features 192 SPUs along with 32 Texture Address Units and 24 Rasterization Operator Units.

Pixel Rate

If using a high screen resolution is important to you, then the GeForce GTX 550 Ti is superior to the GeForce 8800 GS, 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: Bandwidth is the maximum amount of information (in units of MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 are applied in one second. This figure is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the graphics 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 the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
