Compare any two graphics cards:
GeForce 9600 GT 512MB vs GeForce GTX 550 Ti
IntroThe GeForce 9600 GT 512MB features core speeds of 650 MHz on the GPU, and 900 MHz on the 512 MB of GDDR3 RAM. It features 64 SPUs along with 32 TAUs and 16 Rasterization Operator Units.
Compare those specifications to the GeForce GTX 550 Ti, which uses a 40 nm design. nVidia has clocked the core speed at 900 MHz. The GDDR5 memory is set to run at a frequency of 1026 MHz on this model. It features 192 SPUs along with 32 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
In theory, the GeForce GTX 550 Ti should be quite a bit faster than the GeForce 9600 GT 512MB in general. (explain)
Texel RateThe GeForce GTX 550 Ti should be a lot (more or less 38%) better at texture filtering than the GeForce 9600 GT 512MB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 550 Ti is a better choice, by a large margin. (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 max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in a second. It is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number 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 speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
