In blog Micron shares, a word or two about their collaboration with NVIDIA and the Micron GDDR6 used on the cards. Developing high bandwidth gaming capability is not easy. ... Micron delivers GDDR6 as NVIDIA launch partner on GeForce RTX
This hasn't happened since forever - Nvidia being first on DDRx. Mostly due to AMD's cpu division expertise making road for "ATI"
Yeah... reading up a little on Micron's GDDR6 implementation... looks promising. Micron Next-Gen GDDR6
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.
