Compare any two graphics cards:
GeForce GTX 285 2GB vs GeForce GTX 660
IntroThe GeForce GTX 285 2GB comes with core speeds of 648 MHz on the GPU, and 1242 MHz on the 2048 MB of GDDR3 memory. It features 240 SPUs as well as 80 Texture Address Units and 32 Rasterization Operator Units.Compare those specifications to the GeForce GTX 660, which comes with a core clock speed of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 192-bit bus, and uses a 28 nm design. It is made up of 960 SPUs, 80 TAUs, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTX 285 2GB should in theory be a small bit better than the GeForce GTX 660 overall. (explain)
Texel RateThe GeForce GTX 660 will be a lot (about 51%) better at anisotropic filtering than the GeForce GTX 285 2GB. (explain)
Pixel RateThe GeForce GTX 660 is a small bit (more or less 13%) faster with regards to anti-aliasing than the GeForce GTX 285 2GB, and also should be able to handle higher screen resolutions more effectively. (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 maximum amount of information (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the card will be at 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 chip could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs 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 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.
