Compare any two graphics cards:
GeForce GTS 450 1GB vs GeForce GTX 560
IntroThe GeForce GTS 450 1GB has a GPU core clock speed of 783 MHz, and the 1024 MB of GDDR5 memory runs at 902 MHz through a 128-bit bus. It also features 192 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.Compare all of that to the GeForce GTX 560, which features GPU clock speed of 810 MHz, and 1024 MB of GDDR5 memory set to run at 1001 MHz through a 256-bit bus. It also features 336 Stream Processors, 56 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTX 560 should be quite a bit faster than the GeForce GTS 450 1GB in general. (explain)
Texel RateThe GeForce GTX 560 is a lot (about 81%) more effective at texture filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce GTX 560 is the winner, 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 (in units of MB per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the 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 chip could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
