Compare any two graphics cards:
GeForce 9600 GT 1GB vs GeForce GTX 550 Ti
IntroThe GeForce 9600 GT 1GB comes with a clock frequency of 650 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 256-bit bus, and makes use of a 65/55 nm design. It is made up of 64 SPUs, 32 TAUs, and 16 Raster Operation Units.
Compare those specs to the GeForce GTX 550 Ti, which has clock speeds of 900 MHz on the GPU, and 1026 MHz on the 1024 MB of GDDR5 memory. It features 192 SPUs as well as 32 TAUs and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 550 Ti should theoretically be much faster than the GeForce 9600 GT 1GB in general. (explain)
Texel RateThe GeForce GTX 550 Ti should be quite a bit (approximately 38%) more effective at AF than the GeForce 9600 GT 1GB. (explain)
Pixel RateThe GeForce GTX 550 Ti will be a lot (about 108%) better at FSAA than the GeForce 9600 GT 1GB, and also will be capable of handling higher resolutions without losing too much performance. (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 max amount of information (measured in MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics 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 chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour 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 rate is also dependant 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.
