Compare any two graphics cards:
Radeon HD 3650 512MB vs Radeon HD 6670 (OEM) 1GB
IntroThe Radeon HD 3650 512MB comes with a GPU core speed of 725 MHz, and the 512 MB of GDDR3 memory runs at 800 MHz through a 128-bit bus. It also is comprised of 120(24x5) Stream Processors, 8 TAUs, and 4 ROPs.Compare those specifications to the Radeon HD 6670 (OEM) 1GB, which has clock speeds of 800 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 memory. It features 480 SPUs along with 24 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 6670 (OEM) 1GB should be much faster than the Radeon HD 3650 512MB overall. (explain)
Texel RateThe Radeon HD 6670 (OEM) 1GB will be a lot (about 231%) faster with regards to anisotropic filtering than the Radeon HD 3650 512MB. (explain)
Pixel RateIf running with lots of anti-aliasing is important to you, then the Radeon HD 6670 (OEM) 1GB is the winner, 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 maximum amount of data (measured in megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This is worked out 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 in one second. Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
