Compare any two graphics cards:
GeForce GTX 590 vs GeForce GTX 660 Ti
IntroThe GeForce GTX 590 uses a 40 nm design. nVidia has clocked the core speed at 607 MHz. The GDDR5 RAM works at a frequency of 855 MHz on this particular card. It features 512 SPUs along with 64 TAUs and 48 Rasterization Operator Units.Compare those specifications to the GeForce GTX 660 Ti, which has a core clock speed of 915 MHz and a GDDR5 memory speed of 1500 MHz. It also features a 192-bit memory bus, and makes use of a 28 nm design. It is made up of 1344 SPUs, 112 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 590 is 128% quicker than the GeForce GTX 660 Ti in general, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 660 Ti will be much (more or less 32%) better at texture filtering than the GeForce GTX 590. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 590 is the winner, 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. One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at 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 could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
