Evidence-first AI semiconductor analysis: what new silicon claims prove, where bottlenecks move, and whether gains survive at system and economic scale.
Three announcements. Three different evidence boundaries.
Samsung zHBM: Level 0, disclosed target
OpenAI Jalapeño: Level 4, reported workload result
AWS Trainium2: Level 6, reported operation at scale
These are evidence positions for specific claims, not scores for the products.
Each one leaves a different next question:
• zHBM: a defined physical measurement
• Jalapeño: sustained operation and full-system cost
• Trainium2: utilization, system energy, and comparative economics
This is how Silicon Atlas will analyze new hardware claims going forward.
