Compare any two graphics cards:
Radeon HD 4830 512MB vs Radeon HD 6670 (OEM) 1GB
IntroThe Radeon HD 4830 512MB has a GPU core speed of 575 MHz, and the 512 MB of GDDR3 memory is set to run at 900 MHz through a 256-bit bus. It also is comprised of 640(128x5) Stream Processors, 32 TAUs, and 16 ROPs.Compare all that to the Radeon HD 6670 (OEM) 1GB, which comes with a clock frequency of 800 MHz and a GDDR5 memory speed of 1000 MHz. It also makes use of a 128-bit bus, and uses a 40 nm design. It features 480 SPUs, 24 TAUs, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthThe Radeon HD 6670 (OEM) 1GB, in theory, should perform a bit faster than the Radeon HD 4830 512MB in general. (explain)
Texel RateThe Radeon HD 6670 (OEM) 1GB should be just a bit (about 4%) better at AF than the Radeon HD 4830 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 4830 512MB 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 largest amount of data (measured in megabytes per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions. Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second. Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
