Radeon VII with HBM2 had memory bandwidth of 1028GB/s - in 2019. The latest and greatest Geforce 3090 with GDDR6X has 936GB/s, despite launching over 18 months later.I never said any such thing.
I said HBM is a niche product and, because of economy of scale favors GDDR, the progress for HBM is relatively slow. HBM technology is good for controlling thermal footprints but it did not solve the bandwidth competition for AMD. I didn't blame HBM for Fury X shortcomings which in reality came from AMD's small core architecture preference. NVidia chose a large core preference which doesn't share AMD's problems. And I pointed out GDDR6 had 50% better bandwidth than HBM2, which is an advantage when it comes to NVidia's preference in architecture, Its not a perfect explanation but it is the general gist.
GDDR6 does not have better bandwidth.
