Compare any two graphics cards:
GeForce GTX 285 2GB vs GeForce GTX 660 Ti
IntroThe GeForce GTX 285 2GB uses a 55 nm design. nVidia has set the core frequency at 648 MHz. The GDDR3 memory runs at a speed of 1242 MHz on this specific card. It features 240 SPUs as well as 80 TAUs and 32 Rasterization Operator Units.Compare all of that to the GeForce GTX 660 Ti, which has a GPU core clock speed of 915 MHz, and 2048 MB of GDDR5 memory set to run at 1500 MHz through a 192-bit bus. It also features 1344 Stream Processors, 112 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 285 2GB should in theory be a bit superior to the GeForce GTX 660 Ti overall. (explain)
Texel RateThe GeForce GTX 660 Ti is much (about 98%) better at anisotropic filtering than the GeForce GTX 285 2GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce GTX 660 Ti is superior to the GeForce GTX 285 2GB, though only just barely. (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 max amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core 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 one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
