Intel Projects AI Chip Packages Could Reach 240 Millimeters Square - www.tokenpost.com

The 240mm² figure is not a spec-sheet footnote—it is a strategic declaration. At that footprint, Intel is assembling four to six compute tilelets with I/O and HBM stacks into a single package, a configuration that directly undercuts TSMC's CoWoS capacity monopoly and signals Intel Foundry's intent to own the full AI accelerator stack on its own 18A/14A nodes. The physics are unforgiving. Thermal density crosses 200W per square centimeter, rendering air cooling obsolete and making liquid cooling non-negotiable. Upstream, EMIB interconnect pitch, reticle dimensions, and substrate warpage all press against hard engineering ceilings. Downstream, server PCB stack-ups, 48V DC power delivery, and chassis airflow must be redesigned from the ground up. Strategically, in-house packaging at this scale is a deliberate hedge against export-control-driven CoWoS bottlenecks in China's Taiwan, yet the economics are punishing: every one-percent yield slip at 240mm² adds roughly eight to twelve percent to per-unit cost—a live-fire test for process nodes still maturing. NVIDIA's dual-die Blackwell and AMD's 3D V-Cache chiplet roadmap are converging on the same endpoint. Over the next twelve to twenty-four months, the real differentiator will not be who hits 240mm² first, but who sustains sub-500W TDP at 85%-plus yield. The package-size race will likely plateau near 250mm², after which the battleground shifts decisively to 3D stacking density and optical I/O bandwidth.
