↳ CAF WATCHER // CONTINUOUS PHYSICAL AUDIT LEDGER
Samsung Electronics (HBM4 & GAA Foundry Substrate) Grade A
Global memory monolith and semiconductor foundry: HBM3e/HBM4 stacked DRAM, 2nm GAA wafers, and Pyeongtaek mega-fabs · Category: Hardware & Physical Substrate
Executive Physical Feasibility & Delivery Audit
Institutional Baseline: Evaluated under the Compute Availability Factor (CAF v1.0) specification by Richie Adomako (Serpens Inc., ResearchGate ID 414150400). CAF 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.

Physical Coupling Pillars (E, T, N, O)
-
Power & Grid Substrate (E = [object Object]): 92/100. Direct connection to KEPCO's high-voltage backbone with multiple redundant on-site step-down substations capable of sustaining multi-gigawatt continuous loads.
-
Thermal Dissipation & CDU Limits (T = [object Object]): 88/100. Engineered industry-leading thermal dissipation across both the wafer scale (cleanroom chillers) and the package scale (reducing thermal resistance between stacked HBM dies by 20%).
-
Cluster Topology & Optical Fabric (N = [object Object]): 94/100. Pyeongtaek fabs are civil engineering marvels: hundreds of kilometers of automated robotic ceiling rails (OHT) transporting wafer pods (FOUPs) between tools with zero human touches.
-
Silicon & Operational Availability (O = [object Object]): 94/100. One of only two companies on Earth (alongside TSMC) capable of fabricating sub-3nm Gate-All-Around silicon, and the global leader in overall DRAM market share.
