↳ CAF WATCHER // CONTINUOUS PHYSICAL AUDIT LEDGER

Groq (LPU Inference Substrate) Grade A-

Deterministic Language Processing Unit (LPU) architecture bypassing HBM memory bottlenecks for ultra-low-latency real-time inference · Category: Hardware & Physical Substrate

Executive Physical Feasibility & Delivery Audit

Institutional Baseline: CAF Watcher evaluates stated accelerator capabilities against empirical physical reality (interconnection queues, electrical substations, liquid cooling heat transfer, and optical network fabrics). Missing public evidence is classified as unknown—it is never treated as zero capacity. Operator telemetry strengthens assessments, but participation is never mandatory.

Physical Coupling Pillars

Power & Grid Substrate (E): 78/100. Secured ~420 MW contracted datacenter capacity across specialized high-density colocation partners in Texas, Arizona, and the Nordics.
Thermal Dissipation & CDU Limits (T): 82/100. High thermal flux density: dissipating 50 kW per standard 42U rack requires precision airflow containment and direct-to-rack coolant distribution units (CDUs).
Cluster Topology & Optical Fabric (N): 90/100. No Ethernet or InfiniBand overhead for intra-rack chip communication; direct chip-to-chip copper interconnects running deterministic routing protocols.
Silicon & Advanced Packaging (O): 86/100. Crucial strategic advantage: uses standard monolithic packaging without complex CoWoS interposers or HBM memory stacks, bypassing Taiwan packaging queues.

Attributable Public Evidence Ledger
