Compare any two graphics cards:
GeForce 9600 GT 512MB vs GeForce GTX 550 Ti
IntroThe GeForce 9600 GT 512MB comes with a core clock frequency of 650 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit bus, and makes use of a 65/55 nm design. It features 64 SPUs, 32 TAUs, and 16 Raster Operation Units.
Compare those specs to the GeForce GTX 550 Ti, which comes with a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also makes use of a 192-bit bus, and makes use of a 40 nm design. It is comprised of 192 SPUs, 32 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 550 Ti should in theory be quite a bit better than the GeForce 9600 GT 512MB overall. (explain)
Texel RateThe GeForce GTX 550 Ti should be quite a bit (about 38%) better at AF than the GeForce 9600 GT 512MB. (explain)
Pixel RateThe GeForce GTX 550 Ti will be quite a bit (approximately 108%) faster with regards to AA than the GeForce 9600 GT 512MB, and will be capable of handling 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: Memory bandwidth is the maximum amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
