Compare any two graphics cards:
GeForce 9500 GT DDR2 vs GeForce GTX 660
IntroThe GeForce 9500 GT DDR2 has a core clock speed of 550 MHz and a DDR2 memory frequency of 500 MHz. It also features a 128-bit memory bus, and makes use of a 65 nm design. It is comprised of 32 SPUs, 16 TAUs, and 8 ROPs.Compare all that to the GeForce GTX 660, which makes use of a 28 nm design. nVidia has clocked the core frequency at 980 MHz. The GDDR5 RAM runs at a frequency of 1502 MHz on this particular card. It features 960 SPUs along with 80 Texture Address Units and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 660 is 801% faster than the GeForce 9500 GT DDR2 overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce GTX 660 is a lot (more or less 791%) better at texture filtering than the GeForce 9500 GT DDR2. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTX 660 is the winner, and very much so. (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 max amount of data (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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 bandwidth is, the lower the ability to get to the max fill rate.
