Compare any two graphics cards:
Radeon HD 6670 (OEM) vs Radeon HD 6670 (OEM) 1GB
IntroThe Radeon HD 6670 (OEM) comes with clock speeds of 800 MHz on the GPU, and 1000 MHz on the 512 MB of GDDR5 memory. It features 480 SPUs as well as 24 TAUs and 8 Rasterization Operator Units.Compare all that to the Radeon HD 6670 (OEM) 1GB, which features a core clock frequency of 800 MHz and a GDDR5 memory frequency of 1000 MHz. It also uses a 128-bit memory bus, and uses a 40 nm design. It features 480 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Power Usage and Theoretical BenchmarksBoth cards have the same power consumption.Memory BandwidthBoth cards have the exact same memory bandwidth, so theoretically they should have identical performance. (explain)
Texel RateBoth cards have the exact same texel rate, so in theory they should perform equally good at at anisotropic filtering. (explain)Pixel RateBoth cards have the exact same pixel fill rate, so theoretically they should be equally good at at AA, and be capable of handling the same screen 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. Price Comparison

Display Specifications
Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 texture map elements (texels) that are processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, 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 amount of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
