Semiconductors and Microchips
The UK designated semiconductors as a priority technology in its International Technology Strategy, published in March 2023. Their importance spans net zero, 5G and 6G, quantum computing, AI, space technologies, and defence. The strategy acknowledges the complexity of global chip supply chains and the need for coordinated international risk management.
The government's Fifth Report describes the UK semiconductor sector as comparatively small relative to the US and Asia. UK strengths lie in design, intellectual property, and compound materials, but vulnerabilities arise from the absence of an end-to-end domestic supply chain. The UK remains heavily dependent on Taiwan, a risk highlighted by pandemic disruptions and geopolitical tensions.
In November 2022, the government blocked Nexperia's takeover of the UK's largest chip manufacturing facility. The decision reflected concerns about national security and supply chain resilience. It also underscored the UK's intention to maintain strategic autonomy in critical technologies.
Vietnam's Emerging Role
Vietnam is rapidly positioning itself as a semiconductor hub. It is currently the third-largest chip supplier to the US after Malaysia and Taiwan. Major investments, including Samsung's USD 850 million expansion, signal Vietnam's growing importance.
In September 2023, the US announced that companies such as Intel, Synopsys, and Amkor will shift parts of their supply chains to Vietnam. The country plans to train 50,000 engineers by 2030 to address workforce shortages. Vietnam is developing semiconductor clusters to attract further foreign direct investment.
However, Vietnam's progress remains uneven. Intel reportedly abandoned plans for a USD 1 billion expansion due to concerns about bureaucracy and power reliability. Media reports suggest Singapore or Malaysia may have been preferred alternatives.
The UK's Investment Challenges
The UK has faced similar setbacks. In June 2023, Intel confirmed plans to build 2 factories in Magdeburg, Germany, creating 10,000 jobs. Intel said in 2021 that post-Brexit conditions meant the UK could no longer be considered for major manufacturing sites.
Intel aims to leverage EU market growth and access multi-billion subsidies subject to European Commission approval. Intel will build additional plants in Poland, Ireland, Spain, Italy, and France. These decisions highlight the competitive landscape for attracting semiconductor investment.
Despite this, Intel remains connected to the UK through market dynamics. Nvidia and AMD announced plans to release chips based on Arm's intellectual property by 2025, causing fluctuations in Intel's stock price. Apple has already transitioned from Intel to Arm processors, and reports suggest Microsoft devices may follow.
Intel's CEO Pat Gelsinger dismissed these developments as having "pretty insignificant roles in the PC business". He emphasised Intel's roadmap and AI's potential. Market analysts view the shift as a challenge to Intel's dominance in PC chips.
Frontier AI Safety and Regulation
The UK's International Technology Strategy identifies ethical barriers to AI adoption. These include limited data quality, workforce shortages, public mistrust, market disincentives, and data monopolies. The lack of coordinated governance and clear regulatory standards is increasingly recognised as a major obstacle.
The Stanford University 2021 AI Index Report ranked the UK third globally for private AI investment at USD 1.9 billion. Combined with the UK's trilateral security partnership with the US and Australia, addressing these barriers is essential for AI deployment. Frontier AI safety has therefore become a national priority.
AI Safety Summit and the AI Safety Institute
The UK hosted the AI Safety Summit in November 2023. Governments, companies, researchers, and civil society groups convened to discuss AI risks and mitigation strategies. Following the summit, Downing Street announced the creation of the world's first AI Safety Institute.
The Institute succeeds the Frontier AI Taskforce and will coordinate international efforts in pre- and post-release testing of frontier AI. Participants include the US AI Safety Institute, Singapore's government, the Alan Turing Institute, Google DeepMind, Microsoft, and OpenAI. Risks under review include bias, misinformation, loss of control, rapid capability jumps, and even "humanity's extinction" as warned by Elon Musk.
Supercomputing Capacity: AIRR and Isambard‑AI
To support research, the Institute will access the AI Research Resource, a network of Europe's supercomputers valued at USD 366 million. Hewlett Packard Enterprise will build the UK's contribution, Isambard‑AI, at the University of Bristol. It will incorporate over 5,000 Nvidia GH200 superchips.
Isambard‑AI will perform up to 200 quadrillion calculations per second and rank among the top ten fastest open science supercomputers worldwide. It will support robotics, climate research, big data, large language model training, and AI-driven drug discovery. The system represents a major leap in UK high-performance computing.
Cambridge's Dawn Supercomputer
The University of Cambridge will connect its Dawn supercomputer cluster to Isambard‑AI. Dawn is currently the UK's fastest supercomputer, and Isambard-AI will surpass it by a factor of ten. This integration marks a significant milestone in combining AI and high-performance computing.
Cambridge, UKAEA, UKRI, Dell Technologies, and Intel developed Dawn in collaboration. It supports research in fusion energy, climate modelling, particle physics, cosmology, engineering, and healthcare. A second phase with increased performance is expected in 2024.
Dell has encouraged the UK government to invest further in AI infrastructure to unlock high growth potential. In parallel, the University of Southampton received USD 18 million to create an AI centre and train over 70 PhD students.
Global Context
AI safety developments coincide with rapid adoption of AI in medical procedures. Addenbrooke's Hospital in Cambridge has introduced AI into liver cancer diagnostics. Similar technologies are already used in lung and kidney tumour treatment across Europe.
Conclusion
Semiconductors and AI continue to evolve at exceptional speed. Their strategic implications are only beginning to emerge as governments and companies reposition themselves. Close monitoring of these developments remains essential.
