Compare any two graphics cards:
GeForce 8800 GT 256MB vs GeForce GTS 450
IntroThe GeForce 8800 GT 256MB comes with a clock frequency of 600 MHz and a GDDR3 memory speed of 700 MHz. It also uses a 256-bit memory bus, and uses a 65 nm design. It is comprised of 112 SPUs, 56 TAUs, and 16 ROPs.Compare all that to the GeForce GTS 450, which comes with GPU core speed of 783 MHz, and 512 MB of GDDR5 memory set to run at 902 MHz through a 128-bit bus. It also features 192 Stream Processors, 32 TAUs, and 16 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the GeForce GTS 450 should be quite a bit faster than the GeForce 8800 GT 256MB in general. (explain)
Texel RateThe GeForce 8800 GT 256MB should be quite a bit (more or less 34%) more effective at texture filtering than the GeForce GTS 450. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce GTS 450 is superior to the GeForce 8800 GT 256MB, 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 max amount of information (measured in megabytes per second) that can be transported past the external memory interface in a second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is calculated by multiplying the total number of 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 per second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
