AI Chips

AMD’s HBM Problem Is the Real Story. The Stock Chart Is Just the Symptom.

Advanced Micro Devices closed at $201.3 on March 22, 2026, sitting 24.7% below its three-month high of $267.1 hit in late January — and the market is almost certainly not pricing in the right reason why. This is not about momentum. It’s about memory. The primary signal here is High Bandwidth Memory allocation tightness. HBM is the scarce, technically demanding ingredient that makes AI accelerators functional at scale. Without it, neither NVIDIA’s H100/H200 series nor AMD’s MI300X/MI350 lineup can train or run frontier models efficiently. The problem — and it’s one that AMD-specific analysis has consistently underweighted — is that SK Hynix and Samsung’s HBM production pipelines were already spoken … Read more

The China Chip Reinstatement Tells You Less Than You Think About Nvidia’s Ceiling

Everyone’s talking about the wrong part of the Nvidia-China story.

Clean. Tidy. Probably incomplete. Here’s the thing: the more interesting detail buried in the Reuters dispatch from March 18 wasn’t that Beijing approved H200 sales. It was that Nvidia is simultaneously adapting Groq’s chip architecture specifically for the Chinese market. Two parallel tracks running at the same time with completely different long-term implications. One is a reinstated export license. The other is a hardware pivot that quietly … Read more
