Compare any two graphics cards:
GeForce GTX 460 1GB vs GeForce GTX 660 Ti
IntroThe GeForce GTX 460 1GB features a GPU core clock speed of 675 MHz, and the 1024 MB of GDDR5 RAM runs at 900 MHz through a 256-bit bus. It also features 336 Stream Processors, 56 TAUs, and 32 ROPs.
Compare those specifications to the GeForce GTX 660 Ti, which comes with clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 memory. It features 1344 SPUs as well as 112 Texture Address Units and 24 ROPs.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
As far as performance goes, the GeForce GTX 660 Ti should theoretically be quite a bit superior to the GeForce GTX 460 1GB in general. (explain)
Texel RateThe GeForce GTX 660 Ti should be a lot (approximately 171%) better at AF than the GeForce GTX 460 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTX 660 Ti is superior to the GeForce GTX 460 1GB, but only just. (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 megabytes per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.
Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated 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 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 maximum amount of pixels the video card can possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
