This hasn't happened since forever - Nvidia being first on DDRx. Mostly due to AMD's cpu division expertise making road for "ATI"

Yep, let NVidia foot the bill this time and AMD can reap the rewards later. 🙂

GDDR6 itself has no challenges in manufacturing, nor does it introduces some costly advanced method of soldering like HBM. https://www.micron.com/resource-details/a87190f8-0822-4635-8f11-254cb773f1e1 https://www.samsung.com/semiconductor/dram/gddr6/ http://www.skhynix.com/eng/pr/pressReleaseView.do?seq=2086&offset=1 If anything, PCB design is more important for achieving high clock. This means that there may be bit different memory OC results on different board designs.

If you're ignoring GDDR5X, I suppose.
