Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs Radeon HD 6670 (OEM)
IntroThe GeForce 8800 GTS (G80) 640MB comes with a core clock frequency of 513 MHz and a GDDR3 memory speed of 792 MHz. It also features a 320-bit bus, and uses a 90 nm design. It features 96 SPUs, 48 Texture Address Units, and 20 ROPs.Compare all that to the Radeon HD 6670 (OEM), which comes with a core clock speed of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is comprised of 480 SPUs, 24 Texture Address Units, and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 6670 (OEM) should perform just a bit faster than the GeForce 8800 GTS (G80) 640MB in general. (explain)
Texel RateThe GeForce 8800 GTS (G80) 640MB will be quite a bit (about 28%) better at texture filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateThe GeForce 8800 GTS (G80) 640MB should be quite a bit (about 60%) better at full screen anti-aliasing than the Radeon HD 6670 (OEM), and capable of handling higher 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: Memory bandwidth is the largest amount of information (in units of MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at 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 graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
