Compare any two graphics cards:
Radeon HD 4670 1GB vs Radeon HD 6670 (OEM) 1GB
IntroThe Radeon HD 4670 1GB comes with clock speeds of 750 MHz on the GPU, and 1100 MHz on the 1024 MB of GDDR4/GDDR3/DDR3/DDR2 RAM. It features 320(64x5) SPUs along with 32 Texture Address Units and 8 ROPs.Compare all that to the Radeon HD 6670 (OEM) 1GB, which has core speeds of 800 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.

Power Usage and Theoretical BenchmarksPower Consumption (Max TDP)
Memory BandwidthTheoretically, the Radeon HD 6670 (OEM) 1GB should be quite a bit faster than the Radeon HD 4670 1GB overall. (explain)
Texel RateThe Radeon HD 4670 1GB should be a lot (more or less 25%) better at AF than the Radeon HD 6670 (OEM) 1GB. (explain)
Pixel RateIf running with a high resolution is important to you, then the Radeon HD 6670 (OEM) 1GB is the winner, but not 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 MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions. Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second. Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated 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 outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.

haha.. 6670 is the best value & performance
I tested graphics card by myself 4670 1G and then tested 6670 2G
4670 faster than 6670
the Winner is 4670
I am very surprised to this test as this card 4670 Old but best of 6670 after testing
DDR5 isn't used in most 6670s--generally it's DDR3. Of course DDR5 would boost performance: I wonder how it would go with the lesser 6670 most would purchase....
