Compare any two graphics cards:
GeForce 8800 GTS (G80) 320MB vs Radeon HD 5670
IntroThe GeForce 8800 GTS (G80) 320MB features a GPU core clock speed of 513 MHz, and the 320 MB of GDDR3 memory runs at 792 MHz through a 320-bit bus. It also is comprised of 96 Stream Processors, 48 TAUs, and 20 ROPs.Compare that to the Radeon HD 5670, which features core clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 400(80x5) SPUs as well as 20 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 5670 is 1% faster than the GeForce 8800 GTS (G80) 320MB overall, due to its higher bandwidth. (explain)
Texel RateThe GeForce 8800 GTS (G80) 320MB is quite a bit (more or less 59%) faster with regards to texture filtering than the Radeon HD 5670. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 8800 GTS (G80) 320MB is the winner, by far. (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 largest amount of information (in units of MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, 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 number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the 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 could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
