AMD is among the squeezed price takers in the memory shortage, paying the same memory bill as Nvidia with a fraction of its pricing power. It is already raising GPU prices just to stand still. In every shortage, money flows to suppliers that quote weekly and away from those locked into annual contracts; memory makers are price setters, while AMD sits in the tier where margins go to die. x.comÂ
AMD's shift from asset-light chip designer to AI systems builder makes it more expensive before it pays off, with thinner margins during the buildout. Equipment spending hit $808 million last quarter versus about $300 million expected, and gross margin came in soft on the Helios rack ramp. The spending is backed by contracted OpenAI and Anthropic deployments, so the long thesis is changed rather than broken, but the market sees the bill before the revenue. x.comÂ
Nvidia retains pricing power if its full system keeps reducing customers' cost per effective AI task. Strong AI demand alone does not ensure profits across the chain: rising chip, memory and optical costs burden buyers, while tighter financing and slow collections threaten operators. Large customers developing their own chips could pressure Nvidia's margins even as the market grows. x.comÂ
Memory's high margins are less durable than those of Nvidia or AMD because memory is a perfect substitute across suppliers and their chips are not. Memory margins have also risen far more than those names', so while chipmakers may eventually see some compression too, it should be smaller than in memory. x.comÂ
AMD could see much more accelerator demand as OpenAI and Anthropic allegedly increase their orders by multiple gigawatts. Nvidia's only real edge over AMD may soon be its size and resources; Lisa Su is a master operator. x.comÂ
AMD and Nvidia face a growing capital burden from substrates without the benefit of foundry margin stacking. Each is committing $1 billion to the substrate ecosystem; AMD has also publicly committed $10 billion to its Taiwan supply chain, more than three times its Q2 net income. That capital is unavailable for R&D and product development, while their gross margins are flat or shrinking. Intel's gross margin is growing as customers prepay its foundry for substrates. x.comÂ
AMD can't undercut Nvidia on price and grow margins while its costs rise faster, and its Helios racks use 50% more HBM than Nvidia's Vera. Lisa Su was evasive about this on the last earnings call. Supply chain constraints and AMD's high P/E are further concerns, even though the company itself is likeable. x.comÂ
AMD's secured wafer supply from TSMC and ramping MI450 demand undercut Morgan Stanley's 43% cut to its AMD GPU demand forecast, especially while it leaves Nvidia's forecast untouched. The market is not buying the downgrade. x.comÂ
Insufficient substrate supply may cap AMD's growth because the company has not secured enough capacity. The author says limited substrate availability drove AMD's lowered guidance, making supply-chain execution the constraint on how far it can grow. This adds an execution risk to the earlier concern that AMD is too expensive to buy despite strong results. x.com x.comÂ
Micron and Sandisk are setting the price on Nvidia's growth ceiling, since memory supply, not demand, now limits Nvidia. Nvidia guided about 70% fiscal 2028 revenue growth, calling the outlook supply constrained, after Q2 revenue of $96 billion. CFO Colette Kress said memory prices face extreme conditions, already above prior expectations and headed higher next year, and Nvidia guided Q4 gross margin down to 71-72% from 75% on memory costs. x.comÂ
AMD's roughly 10% Q4 price increase on Instinct AI accelerators, Radeon GPUs and chipsets reflects demand-backed pricing power. The direct cause is rising TSMC foundry fees, with 5nm wafers near $18,500 and 3nm at $20,000-22,000, and TrendForce, citing Nikkei, expects up to 10% more in 2027; as a fabless company AMD passes the cost on. Ryzen CPUs are excluded so AMD does not cede gaming and midrange PCs before the holidays, as Intel raises PC CPU prices 10% for a third time. x.comÂ
AMD's valuation leaves little room for error even after stellar earnings. Sustaining 40% annual growth to 2030 gives $200B revenue and $80B net income at a 40% margin; at 20x earnings that is $1.6T, or about $990B discounted at 10%, versus $845B today. The market fears its acceleration coincides with the final stage of AI capex growth, as customers diversify from NVIDIA, a tailwind that may fade as capex growth slows after 2027. A solid hold, but new buyers should wait for a bigger decline. … Show more
