Only two-chip laptop motherboards.

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)

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)
