Compare any two graphics cards:
GeForce 9800 GT 1GB vs Radeon HD 6670 (OEM)
IntroThe GeForce 9800 GT 1GB has a GPU core speed of 600 MHz, and the 1024 MB of GDDR3 memory is set to run at 900 MHz through a 256-bit bus. It also is comprised of 112 SPUs, 56 TAUs, and 16 Raster Operation Units.Compare those specifications to the Radeon HD 6670 (OEM), which comes with core clock speeds of 800 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 RAM. It features 480 SPUs as well as 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthAs far as performance goes, the Radeon HD 6670 (OEM) should in theory be a little bit superior to the GeForce 9800 GT 1GB overall. (explain)
Texel RateThe GeForce 9800 GT 1GB should be a lot (about 75%) more effective at AF than the Radeon HD 6670 (OEM). (explain)
Pixel RateThe GeForce 9800 GT 1GB should be much (more or less 50%) faster with regards to full screen anti-aliasing than the Radeon HD 6670 (OEM), and should be able to handle higher resolutions while still performing well. (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 megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second. Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 bandwidth is, the lower the ability to reach the maximum fill rate.
