Compare any two graphics cards:
GeForce GTX 470 vs GeForce GTX 550 Ti
IntroThe GeForce GTX 470 has a GPU core speed of 607 MHz, and the 1280 MB of GDDR5 RAM runs at 837 MHz through a 320-bit bus. It also is made up of 448 SPUs, 56 TAUs, and 40 Raster Operation Units.
Compare those specs to the GeForce GTX 550 Ti, which uses a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 RAM runs at a speed of 1026 MHz on this model. It features 192 SPUs as well as 32 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically, the GeForce GTX 470 should be much faster than the GeForce GTX 550 Ti overall. (explain)
Texel RateThe GeForce GTX 470 should be a bit (more or less 18%) more effective at anisotropic filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 470 is superior to the GeForce GTX 550 Ti, though only just barely. (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.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core clock 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 in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
