Compare any two graphics cards:
Radeon HD 3470 512MB vs Radeon HD 6670 (OEM) 1GB
IntroThe Radeon HD 3470 512MB features a GPU core speed of 800 MHz, and the 512 MB of GDDR3 RAM is set to run at 950 MHz through a 128-bit bus. It also features 40(8x5) Stream Processors, 4 TAUs, and 4 Raster Operation Units.Compare those specifications to the Radeon HD 6670 (OEM) 1GB, which comes with a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 480 SPUs, 24 TAUs, and 8 ROPs.

Power Usage and Theoretical BenchmarksMemory BandwidthThe Radeon HD 6670 (OEM) 1GB, in theory, should perform quite a bit faster than the Radeon HD 3470 512MB overall. (explain)
Texel RateThe Radeon HD 6670 (OEM) 1GB is quite a bit (about 500%) faster with regards to anisotropic filtering than the Radeon HD 3470 512MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 6670 (OEM) 1GB is superior to the Radeon HD 3470 512MB, 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

Display Specifications
Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. If the card has DDR memory, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core clock speed. 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 rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
