Compare any two graphics cards:
GeForce 8800 GTX vs GeForce GTX 550 Ti
IntroThe GeForce 8800 GTX uses a 90 nm design. nVidia has clocked the core speed at 575 MHz. The GDDR3 memory is set to run at a frequency of 900 MHz on this specific model. It features 128 SPUs along with 64 Texture Address Units and 24 ROPs.Compare those specifications to the GeForce GTX 550 Ti, which comes with a core clock frequency of 900 MHz and a GDDR5 memory speed of 1026 MHz. It also features a 192-bit bus, and makes use of a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 550 Ti should in theory be a small bit superior to the GeForce 8800 GTX in general. (explain)
Texel RateThe GeForce 8800 GTX will be much (about 28%) more effective at texture filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 550 Ti is a better choice, and very much so. (explain)
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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the max amount of data (measured in MB per second) that can be transferred across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, 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 processed per second. This number is worked out by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
