Compare any two graphics cards:
GeForce 8800 Ultra vs GeForce GTX 660
IntroThe GeForce 8800 Ultra features core speeds of 612 MHz on the GPU, and 1080 MHz on the 768 MB of GDDR3 memory. It features 128 SPUs as well as 64 TAUs and 24 Rasterization Operator Units.Compare those specifications to the GeForce GTX 660, which makes use of a 28 nm design. nVidia has clocked the core frequency at 980 MHz. The GDDR5 memory runs at a frequency of 1502 MHz on this particular card. It features 960 SPUs as well as 80 Texture Address Units and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 660 is 39% quicker than the GeForce 8800 Ultra in general, because of its greater bandwidth. (explain)
Texel RateThe GeForce GTX 660 is quite a bit (more or less 100%) faster with regards to AF than the GeForce 8800 Ultra. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 660 is the winner, by far. (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: Bandwidth is the largest amount of data (measured in MB per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
