Compare any two graphics cards:
GeForce GTX 260 216SP 55 nm vs GeForce GTX 660 Ti
IntroThe GeForce GTX 260 216SP 55 nm features a clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also features a 448-bit bus, and makes use of a 55 nm design. It is comprised of 216 SPUs, 72 TAUs, and 28 ROPs.Compare those specs to the GeForce GTX 660 Ti, which has a core clock frequency of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 192-bit memory bus, and uses a 28 nm design. It is made up of 1344 SPUs, 112 TAUs, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 660 Ti should perform much faster than the GeForce GTX 260 216SP 55 nm overall. (explain)
Texel RateThe GeForce GTX 660 Ti is much (about 147%) faster with regards to texture filtering than the GeForce GTX 260 216SP 55 nm. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 660 Ti is a better choice, by far. (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. Price Comparison

Display Specifications
Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface within a second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 processed per second. This number is worked out by multiplying the total number of texture units of the card by the core 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 per second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. 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 lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
