REGION / LOCATION MINIMUM
EU — documented minimum
Positive AI accelerator capacity at EU-located frontier facilities identified in Epoch AI's data centre registry. This is not an estimate of all AI compute in the EU.

METHOD LIMIT
This is a documented minimum in a frontier registry, not an estimate of all AI compute in the EU.
The series is location-based and cannot be subtracted from Epoch AI's ownership-based Other category.
Future facility points are plans with uncertain dates and capacity, not observed measurements.

The curve estimates cumulative AI accelerator ownership in the Epoch AI dataset; it does not measure actual use, access, physical location or effective model capacity.
- Coverage follows Epoch AI's ownership model and is not a complete inventory of all computing worldwide.
compute/claim/measurement-scopeH100e is a comparison model that normalises different AI chips against the Nvidia H100's theoretical maximum dense 8-bit performance; it is not a count of H100 cards.
CALCULATION
H100e = peak dense 8-bit OPS/s ÷ 1.979e15; ZOPS = H100e × 1.979e15 ÷ 1e21- Memory, networking, software, precision, utilisation and workload can make actual performance higher or lower than this comparison.
compute/claim/h100e-modelThe EU series sums positive H100e capacity at facilities in the EU's 27 member states included in Epoch AI's selected frontier data centre registry.

- The registry is not a complete inventory of all data centres or all AI capacity in the EU.
- The series uses physical location, while the main series use ownership.
- Non-frontier facilities use Epoch's capacity factor 1.5 and ±6 months for estimated operational dates (80% coverage); this is not the ownership curve's 5th–95th percentiles. Observation dates are not operational-date estimates.
