The claim comes as Nvidia has been widely expected to delay the launch of GPUs such as the expected RTX 4080, due to oversupply of older RTX 30 series models, which have seen a glut of products following the recent crypto crash and miners selling thousands of cards causing retail sales of current models to go below MSRP in some cases.
As website Wccftech says, though, other evidence points at shipping dates for consumers sitting much further into the future. Its discussions with board partners that ship Nvidia GPUs with their own coolers amongst other things, say that they lack even basic information about the new models and have yet to finalize packaging.
A time frame of October or later seems far more likely, giving the current oversupply issue to calm down and presenting a more favorable launch environment for a new range of graphics cards.
This also ties in with production timeline estimates detailed over at Igor's Lab, which point at a launch date more likely in October at the earliest and others pointing at a 2023 launch for some mid-range models such as the RTX 4060.
