Compare any two graphics cards:
GeForce GT 440 1.5GB vs GeForce GTX 660
IntroThe GeForce GT 440 1.5GB features a clock frequency of 594 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 192-bit memory bus, and makes use of a 40 nm design. It features 144 SPUs, 24 TAUs, and 24 ROPs.Compare all of that to the GeForce GTX 660, which makes use of a 28 nm design. nVidia has set the core speed at 980 MHz. The GDDR5 RAM works at a speed of 1502 MHz on this card. It features 960 SPUs as well as 80 Texture Address Units and 24 ROPs.

3DMark Fire Strike Graphics Score
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce GTX 660 will be 234% quicker than the GeForce GT 440 1.5GB in general, due to its greater bandwidth. (explain)
Texel RateThe GeForce GTX 660 will be quite a bit (more or less 450%) better at anisotropic filtering than the GeForce GT 440 1.5GB. (explain)
Pixel RateThe GeForce GTX 660 will be a lot (approximately 65%) faster with regards to full screen anti-aliasing than the GeForce GT 440 1.5GB, and will be able to handle higher screen resolutions better. (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 largest amount of information (counted in MB per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total number of texture units of the card 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of ROPs by the the core 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 is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
