TSMC rumored to experience major 28nm shortage through summer
TSMC builds the chips for mobile and video processors, so if the rumor turns out to be true, it could potentially constrain chip makers and mobile device manufacturers and delay new product launches.
Neither TSMC nor the involved chip makers have commented on the rumors, so we'll have to see how this plays out. It's likely that AMD, NVIDIA, and Qualcomm will be looking for additional manufacturing partners to assist in compensating for the shortfall that could come from this shortage.
