Compare any two graphics cards:
GeForce GTS 450 1GB vs GeForce GTX 660 Ti
IntroThe GeForce GTS 450 1GB makes use of a 40 nm design. nVidia has clocked the core frequency at 783 MHz. The GDDR5 memory works at a speed of 902 MHz on this particular model. It features 192 SPUs as well as 32 Texture Address Units and 16 Rasterization Operator Units.Compare all of that to the GeForce GTX 660 Ti, which comes with core clock speeds of 915 MHz on the GPU, and 1500 MHz on the 2048 MB of GDDR5 RAM. It features 1344 SPUs as well as 112 Texture Address Units and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce GTX 660 Ti, in theory, should be much faster than the GeForce GTS 450 1GB overall. (explain)
Texel RateThe GeForce GTX 660 Ti will be a lot (about 309%) faster with regards to AF than the GeForce GTS 450 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 660 Ti is superior to the GeForce GTS 450 1GB, by a large margin. (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 (measured in megabytes per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics 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 most 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 worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
