Console manufacturers have traditionally had issues having enough supply at launch. Inevitably, some users faced price gouging on Ebay if they were set on getting a console within the first few weeks. According to AMD, they won't be the result of any delays as they are completely capable of making plenty of silicon.
AMD corporate vice president and general manager of Semi-Custom Business Saeid Moshkelani:
From a manufacturing perspective, in a year we ship tens of millions of units. So we have a very strong manufacturing base for our APUs and discrete graphics. We leverage the same manufacturing infrastructure to develop for game consoles. So the volumes were not something that actually raised an eyebrow for us, because we're already in high-volume manufacturing.
This is good news for gamers, provided Sony and Microsoft don't experience supply shortages elsewhere in the manufacturing process. It should mean that more consoles are available at launch, helping to reduce any price gouging that may occur.
