DigiTimes writes that a shortage of nVidia's GeForce4 Ti 4200/4600 and MX 440 chips has started to be reported on the market due the seasonal demand :
According to graphics card makers, the tight supply has been felt most for GeForce4 Ti 4200 and 4600 chips, and so far they do not know when the situation will improve.
Due to the shortage, card manufacturers have begun worrying that their October shipments may be affected.
Given that the graphics chips in short supply are all AGP 4x products, it was rumored that Nvidia had strategically reduced supply to push the transition to AGP 8x technology, which its new NV18 and NV28 chips are based on.
However, card makers believed the rumor unlikely to be true, as the AGP 8x market is still relatively small. With AGP 8x technology only starting to enter the mainstream, the number of supporting motherboards is in fact limited. Besides, due to their higher prices, Nvidia’s new products are not likely to attract customers to opt for the AGP 8x lines immediately.
