Compare any two graphics cards:
GeForce 8800 Ultra vs GeForce GT 450 (OEM)
IntroThe GeForce 8800 Ultra uses a 90 nm design. nVidia has set the core speed at 612 MHz. The GDDR3 memory is set to run at a speed of 1080 MHz on this model. It features 128 SPUs along with 64 TAUs and 24 Rasterization Operator Units.Compare those specs to the GeForce GT 450 (OEM), which has a core clock frequency of 790 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of a 192-bit bus, and uses a 40 nm design. It is made up of 144 SPUs, 24 Texture Address Units, and 24 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the GeForce 8800 Ultra is 8% faster than the GeForce GT 450 (OEM) overall, because of its greater bandwidth. (explain)
Texel RateThe GeForce 8800 Ultra is a lot (about 107%) better at texture filtering than the GeForce GT 450 (OEM). (explain)
Pixel RateIf using high levels of AA is important to you, then the GeForce GT 450 (OEM) is superior to the GeForce 8800 Ultra, 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: Memory bandwidth is the largest amount of data (in units of megabytes per second) that can be transported across the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 video card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). 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.
