Compare any two graphics cards:
GeForce GTX 460 2GB vs GeForce GTX 660 Ti
IntroThe GeForce GTX 460 2GB comes with a GPU core speed of 675 MHz, and the 2048 MB of GDDR5 RAM runs at 900 MHz through a 256-bit bus. It also features 336 SPUs, 56 Texture Address Units, and 32 ROPs.Compare that to the GeForce GTX 660 Ti, which features clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 memory. It features 1344 SPUs along with 112 Texture Address Units and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 660 Ti should perform a lot faster than the GeForce GTX 460 2GB in general. (explain)
Texel RateThe GeForce GTX 660 Ti should be much (approximately 171%) faster with regards to texture filtering than the GeForce GTX 460 2GB. (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GTX 660 Ti is the winner, 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, 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, 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 figure is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
