It's like Tom said, the driver team is coming from an iGpu team which was always limited in what they had to work with and end goal, everything that you see dropping as a driver is this team expanding out from an iGpu team, which is uncharted for Intel to want to be trading paint with AMD /...
Kind of why I jumped to AMD was to carry on with Crossfire thinking they may keep it going building GPU's also, B350 couldn't compete with x58 with the same cards and driver because of the x8 by x8 setup, times have changed with cards like the RX6600 being an x8 card if AMD made a working driver...
Silver has moved to $28oz now and holding, how long can they hold it back is the real question as a much needed raw material for everything, and why they need it to always stay cheap unlike Gold, it is part of the wheel that makes it roll.
I thought this was interesting pickup of information, as I have said before that AMD can run Rebar in PCIe 3 with an Intel Arc GPU, he is using B450 chipset with Ryzen 5 5600x and A770, his goal was to beat the PS5 at $500 budget.

The one piece of technology that AMD could be proud of is no SLi or CX ribbon was needed, and it worked even on RX 570/580.
If the CX driver still exist, what would 5800x 3D look like?
I use to CX with many different setup's, here are the same RX 570 8Gb and 4Gb on a B350 board being handled by my Ryzen 5 3600 in July 2019, http://www.3dmark.com/fs/19974916
