Compare any two graphics cards:
GeForce GTX 285 2GB vs GeForce GTX 660
IntroThe GeForce GTX 285 2GB comes with a GPU core speed of 648 MHz, and the 2048 MB of GDDR3 RAM runs at 1242 MHz through a 512-bit bus. It also is made up of 240 SPUs, 80 Texture Address Units, and 32 ROPs.Compare those specifications to the GeForce GTX 660, which features a clock speed of 980 MHz and a GDDR5 memory speed of 1502 MHz. It also uses a 192-bit memory bus, and makes use of a 28 nm design. It features 960 SPUs, 80 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 theoretically be a bit superior to the GeForce GTX 660 in general. (explain)
Texel RateThe GeForce GTX 660 will be a lot (approximately 51%) faster with regards to texture filtering than the GeForce GTX 285 2GB. (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GTX 660 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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that are applied per second. This figure 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 applied in one second. Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
