Compare any two graphics cards:
GeForce GTS 450 1GB vs Geforce GTX 680
IntroThe GeForce GTS 450 1GB has a core clock speed of 783 MHz and a GDDR5 memory speed of 902 MHz. It also makes use of a 128-bit bus, and makes use of a 40 nm design. It is made up of 192 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.Compare those specifications to the Geforce GTX 680, which makes use of a 28 nm design. nVidia has set the core speed at 1006 MHz. The GDDR5 memory is set to run at a frequency of 1502 MHz on this card. It features 1536 SPUs as well as 128 Texture Address Units and 32 ROPs.
Display Graphs
Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Geforce GTX 680 is 233% quicker than the GeForce GTS 450 1GB in general, because of its greater data rate. (explain)
Texel RateThe Geforce GTX 680 should be much (about 414%) more effective at texture filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateThe Geforce GTX 680 is much (more or less 157%) more effective at FSAA than the GeForce GTS 450 1GB, and also will be capable of handling higher screen resolutions more effectively. (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 data (counted in MB per second) that can be transferred past the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the card's 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 also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
