IBM has unveiled a radical new chip design that stacks transistors vertically like floors in a block of flats, promising a leap in processing power and energy efficiency. The breakthrough, announced at a tech conference in San Francisco, is being hailed as a game-changer for the semiconductor industry and a timely boost for the UK’s own chip strategy. But as a Labour and Economy reporter, I can’t help but wonder: what does this mean for the price of bread, the strength of unions, and the real economy in the North?
Let’s start with the basics. This chip, built using what IBM calls a “vertical transport” architecture, could double the performance of existing processors while cutting power consumption. That means faster phones, smarter AI, and more efficient data centres. For the UK, which has been scrambling to revive its semiconductor sector after decades of decline, this could be a lifeline. The government’s National Semiconductor Strategy, launched last year, aims to boost domestic chip design and manufacturing, but critics say it lacks the firepower of the US CHIPS Act or the EU’s massive subsidies. This IBM innovation, however, could give British firms a technological edge if they can license or adapt the design.
But here’s where it gets tricky. The UK’s chip industry is a shadow of its former self. Once a global leader, with companies like ARM and Plessey, we’ve seen production shift to Asia and design talent poached by US tech giants. The IBM breakthrough is exciting, but it’s a research prototype, not a commercial product. It could be years before we see it in devices, and by then, who will build it? The UK lacks large-scale fabrication plants, or “fabs.” The government has promised £1 billion for the sector, but that’s pocket change compared to the billions thrown at the problem by the US, EU, China and South Korea. Unions have warned that without serious investment, the UK will remain a bit-part player, dependent on foreign-made chips for everything from cars to washing machines.
And that brings me back to the kitchen table. High-tech chips are all well and good, but what about the cost of living? Semiconductors are in everything: fridges, boilers, cars, even the machines that bake our bread. If the UK can’t produce its own chips, we’re vulnerable to supply shocks and price hikes. Remember the chip shortage of 2021? It pushed up car prices, delayed home appliances, and even hit food supply chains. A stronger domestic chip industry could insulate us from such shocks, but only if the benefits reach ordinary workers, not just shareholders.
There’s also the question of jobs. The North, with its history of manufacturing, could be a natural home for new fabs. But the industry needs skilled workers, and the UK has a skills gap. Apprenticeship numbers are down, and university courses in electrical engineering struggle to fill places. Unions are calling for a proper industrial strategy that links chip investment to good jobs, fair wages, and training. Without that, the IBM breakthrough risks being another story of southern prosperity and northern neglect.
Of course, it’s not all doom and gloom. IBM’s announcement shows that British research still punches above its weight. The company’s labs in Hursley, Hampshire, and Zurich, Switzerland, were key to the development. And the UK has strengths in chip design, with ARM’s architecture powering most smartphones worldwide. If the government can bridge the gap between design and manufacturing, we could see a revival. But that requires a long-term commitment, not just a glossy strategy document.
For now, the “block of flats” chip is a promising step, but steps don’t feed families or warm homes. As the Chancellor prepares her next Budget, she should remember that semiconductor strategy isn’t just about tech supremacy. It’s about making sure that when the next innovation lands, it lifts the living standards of working people, not just the profits of a few. That’s the real economy. That’s what matters.
