Radeon HD 6670 (OEM) vs Radeon HD 6670 (OEM) 1GB
Intro
The Radeon HD 6670 (OEM) makes use of a 40 nm design. AMD has set the core frequency at 800 MHz. The GDDR5 RAM is set to run at a frequency of 1000 MHz on this specific model. It features 480 SPUs as well as 24 Texture Address Units and 8 Rasterization Operator Units.Compare all that to the Radeon HD 6670 (OEM) 1GB, which uses a 40 nm design. AMD has set the core speed at 800 MHz. The GDDR5 RAM works at a speed of 1000 MHz on this model. It features 480 SPUs as well as 24 Texture Address Units and 8 ROPs.
Power Usage and Theoretical Benchmarks
Both cards have the same power consumption.Memory Bandwidth
Both cards have exactly the same memory bandwidth, so in theory they should have identical performance. (explain)
Texel Rate
Both cards have exactly the same texel fill rate, so in theory they should perform equally good at at anisotropic filtering. (explain)Pixel Rate
Both cards have the exact same pixel rate, so theoretically they should be equally good at at AA, and be able to handle the same resolutions. (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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in megabytes per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.
Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total texture units of the card by the core clock 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 processed per second.
Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
