Nvidia Has Reportedly Delayed RTX 3090 Ti Launch - IGN - IGN
TweakTown's sources suggest that the RTX 3090 Ti's release has been pushed back, and Videocardz has confirmed this with its own sources, who claim BIOS and hardware issues are responsible for the delay.
PC Gamer has also heard from a GPU manufacturer that the release may have been "temporarily stalled".
TweakTown's report says that manufacturing of the 3090 Ti has been put on hold, and that third-party board partners have also been asked to pause production.
