Compare any two graphics cards:
GeForce 9600 GT 512MB vs GeForce GTX 550 Ti
IntroThe GeForce 9600 GT 512MB comes with core clock 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 ROPs.
Compare those specifications to the GeForce GTX 550 Ti, which has 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 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Performance-wise, the GeForce GTX 550 Ti should in theory be a lot better than the GeForce 9600 GT 512MB in general. (explain)
Texel RateThe GeForce GTX 550 Ti is much (more or less 38%) better at AF than the GeForce 9600 GT 512MB. (explain)
Pixel RateThe GeForce GTX 550 Ti is much (approximately 108%) more effective at anti-aliasing than the GeForce 9600 GT 512MB, and also will be able to handle higher resolutions while still performing well. (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 (measured in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR RAM, the result should 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 AA, High Dynamic Range and higher screen resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
