Overview
AMD (Advanced Micro Devices) is the #2 US AI-accelerator designer behind Nvidia — the other side of the US-AI-chip-designer pair the wiki tracks through the AI DRAM Crisis (its Samsung HBM4 supply MOU) and the China export-control regime. Its Instinct MI400/MI450 line is the 2026 challenger to Nvidia’s Blackwell/Rubin.
Key Facts
- MI400 ramp: the MI450 and the Helios rack-scale platform (MI455X) launch in H2 2026; the MI400 series is projected at ~$7.2B revenue in 2026 (~25% of data-center sales; ~258,000 units at a ~$30,926 ASP). (S&P Global)
- Data-center surge: data-center GPU revenue forecast +114% YoY to $15B in 2026; total data-center revenue +73% to $28.7B. (S&P Global)
- China export hit: the ban on its Instinct MI308 accelerator to China cost ~$800M in one quarter (producing an operating loss) and ~$1.5B in 2025 revenue — the same export regime that foreclosed Nvidia from China. (Data Center Dynamics)
- Memory dependency: AMD signed a March 18, 2026 MOU with Samsung for HBM4 (for the MI455X) and DDR5 (for EPYC Venice CPUs) — wiring it into the AI DRAM Crisis supply squeeze. The Bluff Is Over. The Price Isn’t.
Newsletter Relevance
AMD is the wiki’s evidence that the AI-chip story is a pair, not a monopoly: it faces the same two binding constraints as Nvidia — China export controls (the MI308 ban) and HBM/DRAM supply (Samsung/SK Hynix) — which is why its supply MOUs are load-bearing for the memory-price thesis (AI DRAM Crisis, The Bluff Is Over. The Price Isn’t.). The same export regime that costs AMD ~$1.5B is the Chokepoint Control instrument the wiki tracks; AMD is the second data point confirming the chokepoint binds both designers, not just Nvidia.

- Nvidia — the dominant AI-chip designer under the identical export + memory constraints
- Samsung / SK Hynix — HBM4/DDR5 suppliers (the March 2026 MOU)
- AI DRAM Crisis / The Bluff Is Over. The Price Isn’t. — the memory-supply thesis AMD’s MOUs feed
- Chokepoint Control — export-control-as-leverage (the MI308 China ban)

Open Questions
- Does the MI400/Helios ramp actually close the gap with Nvidia’s Blackwell/Rubin, or does Nvidia’s lead widen?
- How much of AMD’s HBM4 allocation competes directly with Nvidia’s for the same Samsung/SK Hynix capacity — and does that tighten the AI DRAM Crisis?
