AMD SB850 Southbridge Shortage Impacting Motherboard Makers
By
Motherboard makers are seeing tight supply of AMD’s new SB850 southbridge, according to industry sources, adding that one of the main reasons is limited capacity of Taiwan Semiconductor Manufacturing Company’s (TSMC’s) 55nm process. The earliest alleviation of the supply shortage will most likely be in September, sources said.
The company has also postponed the launch of its mainstream southbridge chip, the SB810, which is expected to be cheaper than the SB850. As a temporary solution, most of the makers are pairing 8-series northbridges with the previous-generation SB710 southbridge for their motherboards. AMD declined the opportunity to comment.
