The new facility, dubbed Fab 32, is located in Arizona and is only the second Intel fab that has the capacity to produce 45nm chips.

The biggest impact a new facility will have on the end users is, ultimately, lower prices. Another fab means more processors and perhaps better yield, and with greater supply comes the ability for Intel to lower prices.
