Compare any two graphics cards:
GeForce 9600 GT 1GB vs GeForce GTX 550 Ti
IntroThe GeForce 9600 GT 1GB has a clock frequency of 650 MHz and a GDDR3 memory speed of 900 MHz. It also uses a 256-bit memory bus, and makes use of a 65/55 nm design. It is comprised of 64 SPUs, 32 Texture Address Units, and 16 ROPs.
Compare all that to the GeForce GTX 550 Ti, which comes with a core clock speed 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 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
The GeForce GTX 550 Ti should theoretically be quite a bit faster than the GeForce 9600 GT 1GB overall. (explain)
Texel RateThe GeForce GTX 550 Ti is much (about 38%) faster with regards to AF than the GeForce 9600 GT 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 550 Ti is superior to the GeForce 9600 GT 1GB, 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 maximum amount of information (measured in megabytes per second) that can be moved past the external memory interface within a second. It's worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
