Compare any two graphics cards:
GeForce 9500 GT 512MB GDDR3 vs GeForce GTX 660
IntroThe GeForce 9500 GT 512MB GDDR3 features a core clock speed of 550 MHz and a GDDR3 memory frequency of 800 MHz. It also makes use of a 128-bit memory bus, and makes use of a 55 nm design. It features 32 SPUs, 16 Texture Address Units, and 8 Raster Operation Units.Compare those specs to the GeForce GTX 660, which comes with GPU clock speed of 980 MHz, and 2048 MB of GDDR5 memory running at 1502 MHz through a 192-bit bus. It also is made up of 960 SPUs, 80 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GTX 660 should be quite a bit faster than the GeForce 9500 GT 512MB GDDR3 in general. (explain)
Texel RateThe GeForce GTX 660 should be quite a bit (more or less 791%) better at texture filtering than the GeForce 9500 GT 512MB GDDR3. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 660 is superior to the GeForce 9500 GT 512MB GDDR3, 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
