Compare any two graphics cards:
GeForce 9800 GTX vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce 9800 GTX has a GPU core clock speed of 675 MHz, and the 512 MB of GDDR3 RAM is set to run at 1100 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 16 ROPs.Compare that to the Radeon HD 6670 (OEM) 1GB, which features core speeds of 800 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 480 SPUs as well as 24 Texture Address Units and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe GeForce 9800 GTX should in theory be a small bit faster than the Radeon HD 6670 (OEM) 1GB in general. (explain)
Texel RateThe GeForce 9800 GTX should be much (more or less 125%) more effective at AF than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the GeForce 9800 GTX is a better choice, 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: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This 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 processed in one second. Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
