Compare any two graphics cards:
GeForce GT 240 GDDR5 1GB vs GeForce GTX 660 Ti
IntroThe GeForce GT 240 GDDR5 1GB has a GPU core clock speed of 550 MHz, and the 1024 MB of GDDR5 memory runs at 850 MHz through a 128-bit bus. It also is comprised of 96 Stream Processors, 32 TAUs, and 8 Raster Operation Units.Compare those specs to the GeForce GTX 660 Ti, which has GPU clock speed of 915 MHz, and 2048 MB of GDDR5 RAM running at 1500 MHz through a 192-bit bus. It also features 1344 SPUs, 112 TAUs, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 660 Ti should theoretically perform much faster than the GeForce GT 240 GDDR5 1GB overall. (explain)
Texel RateThe GeForce GTX 660 Ti should be quite a bit (about 482%) better at AF than the GeForce GT 240 GDDR5 1GB. (explain)
Pixel RateIf using a high screen resolution is important to you, then the GeForce GTX 660 Ti is superior to the GeForce GT 240 GDDR5 1GB, 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 largest amount of data (counted in megabytes per second) that can be transported 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 RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 that the graphics chip can possibly record to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
