Compare any two graphics cards:
GeForce 8800 GT 1GB vs Radeon HD 6670 (OEM)
IntroThe GeForce 8800 GT 1GB makes use of a 65 nm design. nVidia has set the core frequency at 600 MHz. The GDDR3 RAM is set to run at a frequency of 900 MHz on this specific model. It features 112 SPUs as well as 56 TAUs and 16 Rasterization Operator Units.Compare those specifications to the Radeon HD 6670 (OEM), which comes with a clock frequency of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also features a 128-bit bus, and uses a 40 nm design. It is made up of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthIn theory, the Radeon HD 6670 (OEM) will be 11% faster than the GeForce 8800 GT 1GB overall, due to its greater bandwidth. (explain)
Texel RateThe GeForce 8800 GT 1GB is much (approximately 75%) faster with regards to AF than the Radeon HD 6670 (OEM). (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce 8800 GT 1GB is the winner, by a large margin. (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 information (measured in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The higher 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 in one second. Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
