Chip Costs Surge, “Waterfall Effect” Disrupted Amid AI Demands

URGENT UPDATE: The semiconductor landscape faces a seismic shift as costs for premium chips surge, threatening the industry’s traditional “waterfall effect.” Chris Bergey, Senior VP at Arm, warns that rising complexity and expenses at the high end could disrupt the flow of advanced technology to budget devices, a practice that has historically benefitted consumers.

In a revealing interview, Bergey emphasized that the escalating costs of developing leading-edge chips—now reaching hundreds of millions of dollars—pose a significant hurdle. For instance, Qualcomm’s latest Snapdragon 8 Elite Gen 5 is reported to cost upwards of $200 per chip, a stark contrast to past pricing. This trend signals a potential breaking point where simply repackaging last year’s technology for cheaper devices may no longer be feasible.

The cost dynamics are changing rapidly. Cutting-edge fabrication processes, particularly from foundries like TSMC, have dramatically increased expenses. Take Apple’s A-series chips as an example: the wafer costs for the A17/A18 Pro built on a 3nm process have skyrocketed from $5,000 in 2013 to around $18,000 in 2024. This three-and-a-half-fold increase in just a decade illustrates the growing financial strain on chipmakers.

Bergey also pointed out that the demand for artificial intelligence capabilities is exacerbating the complexity of chip design. Modern smartphone and PC system-on-chips (SoCs) are now required to integrate not just CPUs and GPUs, but also dedicated AI accelerators and advanced image processors. This has resulted in significant increases in transistor counts—Apple’s A-series chips have exploded from around 1 billion transistors on the A7 to 20 billion on the A18 Pro.

As companies scramble to keep up with these developments, memory costs have also surged. Premium devices now frequently feature 12 to 16 GB of RAM to support on-device AI models, adding to the overall bill for manufacturers. The integration of AI is pushing the boundaries of what consumers expect from their devices, with features like intelligent voice assistants and advanced camera processing becoming standard.

Bergey anticipates a major shift in how companies approach chip design. Instead of relying solely on last year’s high-end models, firms are innovating with new cores specifically targeting mid-range markets. The Arm C1-Premium core, for instance, is 35% smaller yet delivers comparable performance to its higher-end counterparts, allowing for cost-efficient production.

Despite the challenges, the current wave of AI presents new opportunities for chipmakers. Companies are exploring new business models that could subsidize the higher hardware costs through software and services revenue. This could include monetizing AI-driven applications and personalized services, which may offset the slim margins on hardware.

The industry is at a pivotal crossroads. Bergey stated that while the traditional cascade of technology to lower price points is under pressure, the evolution of chip design is far from stagnant. He believes we are entering an “exciting innovation cycle,” driven largely by AI.

As chip costs continue to escalate, consumers may find themselves facing higher prices for advanced features. However, as the industry adapts to these new realities, it is possible that innovations will still trickle down to budget devices, albeit in a different form.

For now, the urgency is evident. The semiconductor landscape is evolving rapidly, and stakeholders from tech enthusiasts to everyday consumers should brace for significant changes ahead. Keep an eye on how these developments will affect your next device purchase, as the future of technology hinges on these critical advancements.
