In particular, the RDNA3 graphics card line launch has been a dud.
The Nvidia 4090 turned out to be far ahead of the AMD 7900XTX.
Then there turned out to be an overheating issue on the AMD cards.
And now it just looks like both Nvidia and AMD are price gouging GPU buyers instead of competing with each other. They are deliberately keeping prices high and creating artificial shortages of GPUs, because that's what kept prices high during covid/crypto mining.
I used to be really cheering for AMD as the underdog, but I guess its true that none of these companies are your friend, they're just there to shake you down.
AMD had a chance to really pull ahead of Nvidia by being "the good guy" and actually offering end users great value for money, but instead they've chosen to emulate Nvidia.
Substantial customer good will has been lost by AMD.
