Plenty of headwinds for Nvidia have emerged recently:
-Declining crypto
-Dead arm acquisition
-Increasingly competitive amd /Intel GPUs (both integrated and discrete)
-Rising tsmc wafer prices
I wouldn't say that things are so bad for Nvidia. They are selling more cards than ever, their "Ultimate Play" to rise the prices across the board will, most likely, be successful in the long run. Sub 200 dollars segment is dead, like sub 100 before it. Since they are going to make monstrous MCM GPUs, the price for an absolute high end is going to rise to unseen heights(performance will rise with them). I hope Intel will stop this madness eventually, but they won't be able to do it fast, even if they try as hard as they can.
