Compare any two graphics cards:
GeForce 8800 GTX vs GeForce GT 450 (OEM)
IntroThe GeForce 8800 GTX has clock speeds of 575 MHz on the GPU, and 900 MHz on the 768 MB of GDDR3 RAM. It features 128 SPUs as well as 64 Texture Address Units and 24 ROPs.Compare all that to the GeForce GT 450 (OEM), which uses a 40 nm design. nVidia has set the core speed at 790 MHz. The GDDR5 memory runs at a speed of 1000 MHz on this model. It features 144 SPUs as well as 24 Texture Address Units and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the GeForce GT 450 (OEM) should theoretically be a small bit superior to the GeForce 8800 GTX in general. (explain)
Texel RateThe GeForce 8800 GTX should be quite a bit (approximately 94%) faster with regards to texture filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateIf using a high resolution is important to you, then the GeForce GT 450 (OEM) is a better choice, 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 largest amount of information (counted in MB per second) that can be transported past the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR type memory, it must 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, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, 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 most pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
