Compare any two graphics cards:
GeForce 8800 GTS (G80) 640MB vs Radeon HD 5670
IntroThe GeForce 8800 GTS (G80) 640MB makes use of a 90 nm design. nVidia has set the core frequency at 513 MHz. The GDDR3 memory is set to run at a frequency of 792 MHz on this specific model. It features 96 SPUs along with 48 TAUs and 20 ROPs.Compare those specifications to the Radeon HD 5670, which comes with core clock speeds of 775 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 400(80x5) SPUs as well as 20 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthPerformance-wise, the Radeon HD 5670 should in theory be just a bit superior to the GeForce 8800 GTS (G80) 640MB in general. (explain)
Texel RateThe GeForce 8800 GTS (G80) 640MB will be much (about 59%) more effective at texture filtering than the Radeon HD 5670. (explain)
Pixel RateIf running with a high resolution is important to you, then the GeForce 8800 GTS (G80) 640MB is superior to the Radeon HD 5670, 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

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
