The Global Centre for Risk and Innovation (GCRI)
National computing capacity rests on processors and accelerators produced in a concentrated global value chain. Access to advanced chips shapes which institutions can run large simulations or train AI, and export controls, shortages and price swings affect public research directly. This page sets out how chip supply affects computing capacity, how dependence is measured, and what evidence serves research and digital agencies planning capacity.

Chips for national computing are the processors and accelerators that public supercomputers and AI facilities are built on. Their supply is concentrated, demand surges raise prices and lead times, export controls restrict access in some countries, and fast hardware generations make procurement timing matter.
For chips and semiconductors, in GCRI's spatial-intelligence reading, the map opens on night lights, population density and true-colour imagery with relief in 3D and true colour from NASA GIBS, framed on the contiguous United States; every other NASA layer, live feed and forecast waits in the layer list.

Critical compute hardware and supply chains. The dossier below sets out how the risk develops, what is measured, where the data come from, how it is modelled and who decides.
Modern HPC and AI rely on GPUs and other accelerators from few designers, manufactured at few advanced fabs. Supply constraints directly limit capacity.
Controls on advanced chips and manufacturing tools limit which countries and institutions can buy leading hardware.
Demand for AI accelerators can outstrip supply, raising prices and lead times for public research buyers competing with large firms.
Each generation brings efficiency gains, so older hardware becomes costly to run per unit of work. Procurement timing matters.
Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| GPU | A graphics processing unit, widely used as an accelerator for simulation and AI. |
| Lead time | The time between placing an order and receiving the hardware. |
| Total cost of ownership | The full cost of a system over its life, including energy, staff and facilities. |
Each indicator carries its unit, its cadence, the kind of source behind it and the evidence label a value would carry. No values are shown: a programme supplies them under its own authority.
| Indicator | Unit | Cadence | Source type | Label |
|---|---|---|---|---|
| Lead time for accelerator procurement | weeks | per procurement | Procurement records | OBSERVED |
| Share of national compute on imported accelerators | percent | per assessment | Inventory of systems | ESTIMATED |
| Accelerator price per unit of performance | currency per teraflop | per procurement | Procurement and market data | ESTIMATED |
| Export control measures affecting computing | count | per change | Government notices | OFFICIAL |
| Hardware age of national systems | years since installation | annual | System inventories | OBSERVED |
| Diversity of processor architectures | count of architectures in national systems | per assessment | System inventories | OBSERVED |
The topic as a computational graph: named sources feed the methods, an evidence review gates the outputs, and the decisions stay with the authorities that hold them.
Fig. 02Nodes carry their type, two metric rows and a state; connectors show what feeds what; dashed frames name the owners; the timeline is the cadence. Design of the pipeline, not a record of a run.

Leading-edge fabrication plants cost enormous sums and take years to build, so only a few firms can operate them. They depend on highly specialized lithography and process equipment from an equally small set of suppliers, and on ultra-pure materials, gases and water. Fabrication itself needs very reliable power and large volumes of water.
Because each stage is concentrated, the chain behaves like a series of single points of failure. Demand shocks, such as rapid growth in AI accelerators, can create shortages that last until new capacity is built. Policy measures to diversify supply take years to change the physical picture, and they may also fragment markets.
Tracing suppliers stage by stage. Limits: deeper tiers are often opaque and commercially sensitive.
Measures of market share and geographic concentration. Limits: describe exposure, not likelihood of disruption.
Overlaying fabrication locations with natural hazard and water stress data. Limits: site resilience measures are not public.
Understanding process constraints through physics and quantum science. Limits: technology roadmaps change quickly.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
