Compare any two graphics cards:
GeForce 8800 GTX vs GeForce GT 450 (OEM)
IntroThe GeForce 8800 GTX uses a 90 nm design. nVidia has set the core speed at 575 MHz. The GDDR3 memory works at a frequency of 900 MHz on this specific model. It features 128 SPUs along with 64 Texture Address Units and 24 Rasterization Operator Units.Compare those specifications to the GeForce GT 450 (OEM), which comes with a core clock speed of 790 MHz and a GDDR5 memory speed of 1000 MHz. It also uses a 192-bit memory bus, and uses a 40 nm design. It is made up of 144 SPUs, 24 Texture Address Units, and 24 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GT 450 (OEM) should theoretically be a little bit superior to the GeForce 8800 GTX overall. (explain)
Texel RateThe GeForce 8800 GTX is a lot (more or less 94%) more effective at texture filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateThe GeForce GT 450 (OEM) is much (approximately 37%) better at anti-aliasing than the GeForce 8800 GTX, and able to handle higher screen resolutions without losing too much performance. (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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
