Compare any two graphics cards:
GeForce 8800 GTX vs GeForce GT 450 (OEM)
IntroThe GeForce 8800 GTX uses a 90 nm design. nVidia has clocked the core speed at 575 MHz. The GDDR3 RAM works at a speed of 900 MHz on this specific card. It features 128 SPUs along with 64 Texture Address Units and 24 Rasterization Operator Units.Compare that to the GeForce GT 450 (OEM), which comes with clock speeds of 790 MHz on the GPU, and 1000 MHz on the 1536 MB of GDDR5 RAM. It features 144 SPUs as well as 24 TAUs and 24 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the GeForce GT 450 (OEM) is 11% quicker than the GeForce 8800 GTX overall, because of its higher data rate. (explain)
Texel RateThe GeForce 8800 GTX is a lot (about 94%) more effective at anisotropic filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateThe GeForce GT 450 (OEM) is quite a bit (more or less 37%) faster with regards to full screen anti-aliasing than the GeForce 8800 GTX, and should be capable of handling 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 max amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at 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 card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
