Global · AI compute race

The AI race: US vs China vs Europe across the stack, and where Ireland sits

The US leads on compute, chips and frontier models: about three-quarters of GPU-cluster compute (Epoch AI, May 2025), 45% of world data-centre electricity (IEA, 2024) and 19 of 25 models above 10^25 FLOP (Epoch). China has 15% of compute, 5 such models and leads routed usage (59% of OpenRouter tokens). Europe has 15% of data-centre electricity, about 8% of compute and none. Ireland's data centres use 23% of its electricity (CSO, 2025).

Where Ireland sits. Ireland is a large host of cloud data centres and a heavy user of power for them (23.2% of electricity, 2025), but it has none of the GPU clusters or large AI sites in Epoch's trackers, no frontier lab HQ, and a €10m stake in a French-led gigafactory bid rather than a site of its own. See AI data centres in Ireland and EU AI gigafactories.

Our reading. The race is not close on the layers that decide who trains frontier models: compute, chips and lab funding. Europe's strengths in this table are demand-side (data-centre load and spend through US clouds) and public money (gigafactories), which arrive after the private US build-out. The counter-argument, that sovereignty spending is protectionism with little payoff, is tested on the Europe scorecard; this page only measures position.

Epoch's GPU-cluster data covers clusters operating to mid-2025 and an estimated 10–20% of world GPU-cluster performance; Chinese entries are partly anonymised, so China's share is understated in our sum. Epoch's own published shares (US about 75%, China 15%) are shown alongside. Epoch's AI data-centre database tracks the largest AI sites (mostly in the US) by satellite and permits; it is not a census, and a site missing from it is not proof there is none. Chip-owner figures are Epoch model estimates (median) of cumulative AI-chip capacity in H100-equivalents; owners outside the named hyperscalers and China are pooled as 'Other', so Europe can't be split out. IEA figures are 2024 estimates and 2030 base-case projections; Europe is the IEA's own regional definition. Hyperscaler capex for Chinese companies is not in this dataset; see hyperscaler capex.

Questions people ask

Who is winning the AI race, the US or China?
On the numbers here, the US: about three-quarters of GPU-cluster compute against China's 15% (Epoch AI, May 2025), 19 of the models above 10^25 FLOP in Epoch's data against 5 for China, and $285.9bn of private AI investment in 2025 against $12.4bn (AI Index 2026). Chinese developers lead on tokens routed through OpenRouter (58.8% in the last 30 days).
Where does Europe stand in the AI race?
Behind on compute, chips and models. Europe uses 15% of world data-centre electricity (IEA, 2024) but holds about 8% of tracked GPU-cluster compute, designs none of the AI chips in Epoch's capacity data, and has 0 models above 10^25 FLOP with published estimates.
How much AI compute does Europe have?
About 8.3% of the GPU-cluster compute in Epoch AI's data (clusters operating to mid-2025), led by Germany, Norway, France and Switzerland. Epoch's AI data-centre tracker lists 243 MW of large AI sites in Europe against 11,851 MW in the US.
How much electricity do data centres use in the US, China and Europe?
The IEA estimates data centres used about 415 TWh worldwide in 2024, 1.5% of world electricity: 45% in the US, 25% in China and 15% in Europe. It projects about 945 TWh by 2030.
How does Ireland fit into the AI race?
Ireland hosts many cloud data centres, which used 7.7 TWh or 23.2% of its metered electricity in 2025 (CSO). It has no GPU clusters or large AI sites in Epoch's trackers and no frontier lab HQ, and has committed €10m to a French-led AI gigafactory bid.
