Compare any two graphics cards:
GeForce 9600 GT 512MB vs Radeon HD 6670 (OEM) 1GB
IntroThe GeForce 9600 GT 512MB has a GPU core speed of 650 MHz, and the 512 MB of GDDR3 memory runs at 900 MHz through a 256-bit bus. It also is made up of 64 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.
Compare that to the Radeon HD 6670 (OEM) 1GB, which comes with GPU clock speed of 800 MHz, and 1024 MB of GDDR5 memory running at 1000 MHz through a 128-bit bus. It also features 480 Stream Processors, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical Benchmarks
Power Consumption (Max TDP)
Theoretically speaking, the Radeon HD 6670 (OEM) 1GB is 11% faster than the GeForce 9600 GT 512MB overall, because of its higher bandwidth. (explain)
Texel RateThe GeForce 9600 GT 512MB is a small bit (approximately 8%) more effective at AF than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateIf running with high levels of AA is important to you, then the GeForce 9600 GT 512MB 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.
Please note that the price comparisons are based on search keywords - sometimes it might show cards with very similar names that are not exactly the same as the one chosen in the comparison. We do try to filter out the wrong results as best we can, though.
Memory Bandwidth: Memory bandwidth is the maximum amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It's calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units by the core speed of the chip. The better the texel rate, the better the video 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 chip could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill 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 get to the max fill rate.
