More memory CapEx may yield proportionally fewer bits as HBM consumes more wafer capacity, supporting SK hynix and Samsung's pricing. Both reported double-digit quarterly DRAM and NAND price gains; Samsung targets 60-70% of mid- to long-term capacity under LTAs. SK hynix has the stronger execution record, but Samsung could benefit enormously from conventional memory without winning HBM4. If trends persist, normalized margins could rise, though memory remains cyclical. x.com 

Intel's production was reportedly affected by a pause at its Israel fabs, which should benefit competitors Arm and AMD. Both look good on that basis. x.com 

Intel's near-term growth is constrained by a Kiryat Gat factory blast and memory-driven PC weakness. The weak Q4 outlook calls for answers: the blast looks set to cut roughly $300 million of revenue in Q4 and could have a similar impact in Q1, limiting data-center growth. Fab ownership gives Intel pricing power and enterprise demand is strong; external foundry customers would add another tailwind if won. CEO Lip-Bu Tan said Nova Lake will allow Intel to take back share. x.com  x.com  x.com  x.com  … Show more

Samsung's HBM4 ramp makes SK hynix's ability to defend its HBM lead the key question in the memory race. Chosun Biz reports SK hynix's HBM4 shipments may have missed expectations for a second straight quarter amid Nvidia Rubin delays and chip tuning. Counterpoint puts Samsung's Q2 HBM share at 33%, up from 21%; TrendForce expects strong SK hynix Q3 profits. Samsung is the preferred memory stock right now, though there may be no single clear winner. SK hynix's October 28 report is the next check. … Show more

Prepaid contracts and demand-paced fabs weaken a broad 2028 memory-glut case. SK hynix says over half its 2027-28 capacity is signed with deposits; 'sold out through 2029' includes negotiations. Samsung targets 60-70% contracted capacity. Micron's three projects begin output in 2H28; tooling follows demand. Reuters says CXMT's 20-30%-yield HBM3E may ship this year to export-restricted Chinese buyers, but performs like older HBM3. Commodity DRAM risks 2028-29 oversupply; NAND could ease in 2H27. … Show more

Intel's poor EMIB-T packaging yields threaten its plans for next year. Per a confidential source, yields are very poor, and EMIB-T may now slip into the following year. The 14A PDK 0.9 matters more for the long term. Intel remains a very strong long-term bull case because yields should improve, though setbacks can arise along the way; whether to avoid this near-term risk is a personal judgment. x.com  x.com  x.com  x.com  x.com  x.com 

Samsung has the most upside among the three memory makers because it holds memory, foundry and packaging under one roof, letting it shorten development cycles and give customers more options. Its HBM4 collaboration on AMD's MI455X with 432GB of HBM4, plus foundry talks, shows a major AI customer taking it seriously again. Expect strong DRAM, NAND and HBM4 contributions. @JonahLupton notes it trades at 4.4x NTM EPS, and HBM prices rising at least 100% in 2027 may not be in estimates. x.com 

Higher HBM stack requirements favor Samsung Electronics shares, even as the broader semiconductor industry suffers and DRAM is in dire straits. Daishin Securities says plans for 4-high and 6-high HBM in low-end inference appear shelved, while Nvidia's 8-high Rubin option appears dropped amid base-die supply constraints and customers' preference for bandwidth. x.com 

SK hynix weighing Intel Foundry for HBM4E base dies would be the validation Intel Foundry has been waiting for: a customer judging it on cost and capability for the most in-demand product in semiconductors, not a subsidy or national-security case. Per @jukan05, SK hynix wants to diversify beyond TSMC, whose base die reportedly costs 3-4x the core memory die, a cost it cannot pass through under long-term HBM deals. Its packaging VP is also evaluating Intel's EMIB against TSMC's CoWoS. x.com 

Samsung Electronics' surging profits show how the AI memory shortage is paying suppliers. Quarterly operating profit reached ₩107tn, nearly nine times a year ago, while sales more than doubled to ₩195.3tn. Alongside SK hynix's results and Microsoft's willingness to pay more for memory, the memory supercycle looks real. x.com
