They should be confident of their ingenuity and product. They shouldn’t be missing an open goal of releasing early and pricing it right to “disrupt the market” like they’ve always said.
They’ll lose more market share as they’ll release too late and with poorer feature set for too high a price for people not to choose Nvidia for a little more.
Do you honestly believe they will lose market share by releasing 2 weeks after Nvidia? Those who are impatient may buy the 5070 if there is enough stock but those who can wait will be in the best position to get the better card.
Releasing early will not suddenly increase their market share either. Most people will still wait for Nvidia cards before making any purchase.
At the end of the day, if the 9070XT beats the 5070 convincingly at a similar price then there will be many who will buy them no matter when it comes out. Taking more time to add FSR4 to more games is absolutely the right move since that will make the biggest impact if it rivals DLSS this time.
