Compare any two graphics cards:
GeForce 8800 GT 512MB vs Radeon HD 6670 (OEM)
IntroThe GeForce 8800 GT 512MB comes with a core clock speed of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also uses a 256-bit bus, and makes use of a 65 nm design. It is comprised of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.Compare those specs to the Radeon HD 6670 (OEM), which has a clock frequency of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also makes use of 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 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 6670 (OEM) should theoretically be a little bit better than the GeForce 8800 GT 512MB in general. (explain)
Texel RateThe GeForce 8800 GT 512MB should be much (more or less 75%) more effective at anisotropic filtering than the Radeon HD 6670 (OEM). (explain)
Pixel RateThe GeForce 8800 GT 512MB is much (approximately 50%) faster with regards to full screen anti-aliasing than the Radeon HD 6670 (OEM), and capable of handling higher resolutions without slowing down too much. (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 (counted in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR RAM, it must be multiplied by 2 once 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 AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The better 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 amount of pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel 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 get to the max fill rate.
