Powering AI’s Future 1 Millimeter at a Time: How AmberSemi Tackles the Chip-Level Energy Bottleneck
The AI revolution is transforming the future of every industry, and data centers are the digital engines making it possible. From powering generative AI to supporting real-time analytics, data centers are being called on to deliver unprecedented levels of performance, speed, and reliability.
NEMA’s study, “A Reliable Grid for an Electric Future” spotlights this challenge, finding that electricity demand is expected to rise 50 percent by 2050 driven by a 300 percent rise in data center energy consumption.
At the center of this surging demand is AI processing, advanced CPUs/GPUs that perform the complex calculations needed for today’s most demanding workloads. These chips are the brains behind everything from language models to automated manufacturing, and their appetite for power is accelerating.
Meeting this need isn’t just about supplying more electricity to the data center itself. Another challenge is improving the efficiency of converting energy from the power line all the way down to the chip level on the motherboard. In most modern data centers, electricity travels through a series of step-down conversions, arriving at over 13,000 volts and then decreasing—480V, 240V, 50V, 12V, and finally 0.8V before it reaches the GPU/CPU. A key goal of the industry today is delivering more power to the chips to do more AI processing. Yet, at each step, a portion of the energy is lost as heat.
Making this process more efficient and delivering more power to the chip enables more AI processing to be possible. That’s where AmberSemi comes in. The company is delivering innovation that helps data centers and their critical AI processing operate more efficiently with less downtime, greater reliability, and more power density to the GPU/CPU.
Rethinking the Power Stack, From Wall to Rack, and from Rack to Chip
AmberSemi is tackling the problem from a new angle—literally. Their 1mm-thick solution sits beneath the processor and delivers power vertically, rather than laterally, dramatically reducing losses. The result: higher efficiency, lower heat, and more power to the chips for AI processing.
“We sit underneath the AI chip and power it directly. We’re bringing density, amps per millimeter squared, driving efficiency, and cutting losses,” AmberSemi CEO Thar Casey says.
In a typical data center, the average efficiency is around 77 percent from wall to rack, and 81 percent from rack to chip. AmberSemi’s technology brings both of those numbers to 90 percent, closing the gap and delivering more of that power through the data center to the motherboard and the CPU/GPU for more AI processing.
A 9 percent gain, as an example, translates to $4.1 billion in potential annual energy savings across U.S. data centers alone, and over 15.7 million tons of CO₂ emissions avoided.
It’s a small footprint with big implications. “In early 2023, an NVIDIA GPU could process AI workloads at a baseline speed. By the end of 2024, that same workload was running 12 times faster,” said Casey. “But to achieve that speed, the system needed three times the power. They need more power, and that’s what we’re bringing.”
Smarter Infrastructure, Not Just Faster Chips
The same AmberSemi technology breakthroughs that can improve power efficiency in data centers are also applied to power management and protection in industrial applications, where uptime, reliability, safety, and energy awareness are paramount.
AmberSemi’s solid-state switch control and protection platform that can power solid-state circuit breakers enables a trip 3,000 times faster than mechanical models, without creating sparks. Their embedded intelligence offers predictive analytics, enabling early fault detection and real-time monitoring.
“When one traditional breaker goes down, it can bring others down with it. That cascading effect costs factories time and money,” says Casey. “With our solid-state solution, the Amber-powered breaker can stop a transient event, like a short circuit, at that first location, protecting the rest of the system from cascading failures, saving up to millions of dollars an hour.”
Solid-state systems powered by AmberSemi’s power management solutions can provide the control and insight necessary to integrate distributed energy, manage peak loads, and increase facility resilience.
Built for Integration, Ready to Partner
AmberSemi is providing next-generation semiconductor solutions to manufacturers; the company is building core power technology that they can use to make their products better. Amber chips are designed to be embedded into the electrical infrastructure NEMA members already produce, from wire systems and panelboards to automation hardware and smart building controls, and more.
“We want to work with all the major electrical product manufacturers and bring next-generation power conversion and control technology to the forefront to upgrade the features, performance, and value their products provide,” Casey adds. “We serve the same market. There’s more happening here than meets the eye.”
The Path Forward Is Smaller, Smarter—and Vertical
As electricity demand accelerates across sectors—from data centers to EV charging to advanced manufacturing—the need for compact, high-performance solutions is urgent. Today’s infrastructure must not only handle more load, but do so with greater efficiency, flexibility, and intelligence. That includes smarter, more efficient endpoint power architectures.
AmberSemi’s approach reimagines how electricity reaches the chip, while also enabling more responsive systems throughout the built environment. One millimeter of innovation may be all it takes to unlock the next era of AI performance and accelerate a second electrical revolution.
