Isn't their APU also capable of doing HBM? There was an Intel AMD hybrid chip that used unified a while back too.
replyMy vega 56 still has 400gb/s of memory which is still insane for how old the card is.
replyAMD's Hawaii architecture had 320GB/s on a 512b GDDR5 bus in 2013.
replyThe Fiji XT architecture after it had 512GB/S on a 4096b HBM bus in 2015.
The Vega architecture did have 400GB/s or so in 2017, which was a bit of a downgrade.
