Compare any two graphics cards:
GeForce GTX 550 Ti vs GeForce GTX 660
IntroThe GeForce GTX 550 Ti features a core clock frequency of 900 MHz and a GDDR5 memory frequency of 1026 MHz. It also features a 192-bit memory bus, and makes use of a 40 nm design. It is comprised of 192 SPUs, 32 Texture Address Units, and 24 Raster Operation Units.Compare those specifications to the GeForce GTX 660, which uses a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 memory is set to run at a speed of 1502 MHz on this specific model. It features 960 SPUs along with 80 TAUs and 24 Rasterization Operator Units.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GTX 660 should theoretically be quite a bit better than the GeForce GTX 550 Ti in general. (explain)
Texel RateThe GeForce GTX 660 will be much (approximately 172%) faster with regards to anisotropic filtering than the GeForce GTX 550 Ti. (explain)
Pixel RateThe GeForce GTX 660 should be a little bit (approximately 9%) better at FSAA than the GeForce GTX 550 Ti, and should be able to handle higher resolutions without slowing down too much. (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

Memory Bandwidth: Bandwidth is the largest amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better 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 are processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, 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 that the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
