Compare any two graphics cards:
GeForce 9600 GT 1GB vs GeForce GTX 550 Ti
IntroThe GeForce 9600 GT 1GB comes with a GPU core speed of 650 MHz, and the 1024 MB of GDDR3 RAM runs at 900 MHz through a 256-bit bus. It also features 64 SPUs, 32 TAUs, and 16 Raster Operation Units.
Compare those specs to the GeForce GTX 550 Ti, which has GPU core speed of 900 MHz, and 1024 MB of GDDR5 memory running at 1026 MHz through a 192-bit bus. It also features 192 Stream Processors, 32 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 550 Ti will be 71% quicker than the GeForce 9600 GT 1GB overall, because of its greater data rate. (explain)
Texel RateThe GeForce GTX 550 Ti will be a lot (approximately 38%) more effective at texture filtering than the GeForce 9600 GT 1GB. (explain)
Pixel RateThe GeForce GTX 550 Ti will be a lot (about 108%) more effective at FSAA than the GeForce 9600 GT 1GB, and able to handle higher screen resolutions more effectively. (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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 can be processed per second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.
Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
