Compare any two graphics cards:
Radeon HD 3850 512MB vs Radeon HD 6670 (OEM) 1GB
IntroThe Radeon HD 3850 512MB features a GPU core clock speed of 668 MHz, and the 512 MB of GDDR3 memory is set to run at 828 MHz through a 256-bit bus. It also is made up of 320(64x5) SPUs, 16 TAUs, and 16 ROPs.Compare all that to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. AMD has clocked the core frequency at 800 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this model. It features 480 SPUs along with 24 TAUs and 8 ROPs.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically speaking, the Radeon HD 6670 (OEM) 1GB should be 21% quicker than the Radeon HD 3850 512MB in general, due to its higher bandwidth. (explain)
Texel RateThe Radeon HD 6670 (OEM) 1GB should be quite a bit (more or less 80%) faster with regards to AF than the Radeon HD 3850 512MB. (explain)
Pixel RateIf running with a high screen resolution is important to you, then the Radeon HD 3850 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, it should 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 AA, High Dynamic Range and high resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 bandwidth is, the lower the ability to reach the maximum fill rate.
