Yields of Taiwan Semiconductor Manufacturing Company's (TSMC's) 40nm process will not see any significant improvement until August 2009, according to sources at graphics card makers.
Since TSMC's yield rates at 40nm are currently less than 25%, they have seriously impacted AMD's shipment schedule for its ATI Radeon HD 4770 graphics chips, the sources noted, adding that TSMC is offering preferential quotes to AMD as compensation.
