Laptop motherboards with two or more chips are considered valuable. These designs were common until around 2006–2007, when manufacturers began integrating the northbridge and southbridge functions into a single chipset. (2006)
Older (2001) 2-chip laptop motherboards have nearly twice the precious metal content of newer ones due to thicker gold plating, larger components, and less integration. Newer boards are more compact and cost-optimized, with reduced metal recovery value (2001)
