Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 5670
IntroThe GeForce 8800 GTS (G80) 320MB comes with a core clock frequency of 513 MHz and a GDDR3 memory speed of 792 MHz. It also makes use of a 320-bit memory bus, and makes use of a 90 nm design. It is made up of 96 SPUs, 48 Texture Address Units, and 20 ROPs.Compare all that to the Radeon HD 5670, which features a clock speed of 775 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit memory bus, and uses a 40 nm design. It is made up of 400(80x5) SPUs, 20 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 5670 should in theory perform a little bit faster than the GeForce 8800 GTS (G80) 320MB overall. (explain)
Texel RateThe GeForce 8800 GTS (G80) 320MB will be a lot (approximately 59%) faster with regards to AF than the Radeon HD 5670. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 8800 GTS (G80) 320MB 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 max amount of data (in units of MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the graphics 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 that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
