Samsung Electronics (005930 KS) and SK Hynix (000660 KS) are expected to expand the 8-speed ratio in the shipment of the 6th generation high bandwidth memory to NVIDIA (NVDA), according to ZDNet Korea

Reports of this kind on next-generation high bandwidth memory supply to the dominant accelerator customer have been a recurring driver of relative moves in the Korean memory pair, with the shares tending to trade on qualification progress and shipment mix rather than on total volumes. The operative distinction is between 8-high and taller-stack configurations: the 8-high product has historically been the more commoditised tier, where both vendors shipping broadly implies intensifying competition on price and share, whereas leadership in taller stacks has been the margin and valuation differentiator. Reports sourced from local trade press on shipment ratios have a mixed track record and are often revised or clarified by company commentary, so confirmation typically comes via earnings calls and disclosure rather than the initial wire. The follow-ons that matter are whether qualification status at the customer is affirmed, how the mix split between the two suppliers evolves into the next product generation, and any read-across to the third memory vendor's positioning. As a supply-chain report rather than a company announcement, the signal is directional on relative share, not on absolute demand.
