Compare any two graphics cards:
GeForce 8800 GT 1GB vs GeForce GTS 450 1GB
IntroThe GeForce 8800 GT 1GB features a GPU core speed of 600 MHz, and the 1024 MB of GDDR3 RAM is set to run at 900 MHz through a 256-bit bus. It also features 112 SPUs, 56 TAUs, and 16 Raster Operation Units.Compare that to the GeForce GTS 450 1GB, which comes with a GPU core clock speed of 783 MHz, and 1024 MB of GDDR5 RAM running at 902 MHz through a 128-bit bus. It also is comprised of 192 Stream Processors, 32 TAUs, and 16 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the GeForce GTS 450 1GB should in theory be a small bit superior to the GeForce 8800 GT 1GB in general. (explain)
Texel RateThe GeForce 8800 GT 1GB will be quite a bit (about 34%) more effective at anisotropic filtering than the GeForce GTS 450 1GB. (explain)
Pixel RateIf using lots of anti-aliasing is important to you, then the GeForce GTS 450 1GB is a better choice, 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: Memory bandwidth is the max amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
