Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce 8800 GTS (G80) 320MB features a GPU core speed of 513 MHz, and the 320 MB of GDDR3 RAM runs at 792 MHz through a 320-bit bus. It also is made up of 96 Stream Processors, 48 TAUs, and 20 ROPs.Compare those specs to the Radeon HD 6670 (OEM) 1GB, which features GPU clock speed of 800 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also is comprised of 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6670 (OEM) 1GB should theoretically be a small bit superior to the GeForce 8800 GTS (G80) 320MB in general. (explain)
Texel RateThe GeForce 8800 GTS (G80) 320MB should be quite a bit (more or less 28%) more effective at texture filtering than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateThe GeForce 8800 GTS (G80) 320MB should be much (approximately 60%) better at AA than the Radeon HD 6670 (OEM) 1GB, and will be able to handle higher resolutions while still performing well. (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 data (in units of MB per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster 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 texture map elements (texels) that are processed in one second. This is worked out 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 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 number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
