Now DigiTimes heard rumors that the real reason of the delay is because AMD is not able to hit satisfactory clockspeeds. Presumably, after the controversy about the Ryzen 3000 series not hitting their advertised Boost speeds, AMD doesn't want to take any risks with its upcoming 16-core desktop flagship.
Unsatisfactory clock speeds are the cause of AMD delaying launch of its 16-core Ryzen 9 3950X processor, which has nothing to do with support from its foundry partner TSMC, according to sources at motherboard makers.
