DigiTimes heard AMD's new SB850 southbridge is seeing tight supply due to limited 55nm capacity at TSMC. To alleviate the situation, motherboard makers are temporarily pairing the old SB710 southbridge with 8-series northbridges.
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.
