Radeon HD 4670 1GB vs Radeon HD 6670 (OEM) 1GB
Intro
The Radeon HD 4670 1GB uses a 55 nm design. AMD has set the core speed at 750 MHz. The GDDR4/GDDR3/DDR3/DDR2 memory is set to run at a speed of 1100 MHz on this model. It features 320(64x5) SPUs along with 32 TAUs and 8 Rasterization Operator Units.Compare all that to the Radeon HD 6670 (OEM) 1GB, which has a clock speed of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit bus, and makes use of a 40 nm design. It features 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (in units of MB per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the 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 can be processed in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.
Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called 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 - the lower the bandwidth is, the lower the ability to get to the maximum 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....
