PowerLattice Cuts Chip Power Use By 50% With Novel Chiplet Tech
PowerLattice, a startup founded in 2023 by engineers from Qualcomm, NUVIA, and Intel, claims to have slashed chip power consumption by over 50%.
Ex-Intel CEO Pat Gelsinger recently invested in the company, spotlighting its power-saving chiplet design. This is a clear bet on a mechanism that radically shifts semiconductor energy constraints.
The core leap is their novel chiplet architecture, which distributes processing tasks across smaller specialized units instead of monolithic chips. This shift breaks longstanding thermal and energy limits tied to traditional chip manufacturing.
Reducing chip power requirements by over 50% transforms how data centers, mobile devices, and AI hardware scale energy use and heat management—crucial operational constraints in 2025.
How Distributing Workloads Around Chiplets Overcomes Energy Bottlenecks
The traditional model centralizes compute in large, often complex chips, creating critical power and heat density challenges.
PowerLattice’s chiplet approach slices workloads into modular cores, each optimized for specific tasks. This decouples power distribution and minimizes leakage currents, dramatically cutting energy waste.
This is more than module miniaturization. It's repositioning the energy constraint from local transistor efficiency to inter-chip communication optimization, which the company addresses by leveraging advanced interconnects and material science innovations.
Such a system redefines the physical limits imposed by monolithic chip layouts and thermal throttling, enabling chips to sustain higher performance with far less power draw.
Why Ex-Intel CEO Pat Gelsinger’s Investment Signals Strategic Confidence

Having led Intel through manufacturing challenges, Gelsinger’s move shows faith that chiplet architectures are the lever semiconductor operators need to break the power scaling plateau hampering AI and edge computing.
This investment also illustrates a shift from conquering raw process node shrinks to architectural innovations that bypass thermodynamic ceilings without relying solely on costly fab upgrades.
The move resembles how AI startups redefine scaling economics by shifting cost constraints instead of incremental efficiency improvements—a dynamic explored recently in how AI companies redefine scaling economics.
Power Saving Chiplets Reposition Energy From Cost to System Design
Most chip power-saving efforts focus narrowly on transistor-level improvements or voltage/power gating. PowerLattice flips this by changing the system's fundamental power distribution mechanism.
This shifts the constraint from needing ever smaller transistors to optimizing chiplet communication and workload partitioning. It converts a physical scaling ceiling into a system-level design problem—one that is far more flexible and compounding over time.
The consequence: a compounding operational cost advantage as chips become more modular and efficient. At scale, data centers running PowerLattice chiplets could cut electricity bills dramatically while pushing performance.
This mechanism also unlocks new product form factors, such as ultralow-power AI inference devices and mobile chips with extended battery life without sacrificing speed.
Comparing Alternatives: Why Chiplets Over Monolithic and Traditional Packaging
Monolithic chip designs, despite decades of scaling, now hit power-density walls requiring complex cooling and power infrastructure.
Other alternatives like 3D-stacking or silicon interposers improve density but still face thermal limits and complex supply chains.
PowerLattice’s chiplet architecture uses simpler, smaller dies interconnected in a system optimized for power distribution and thermal efficiency without expensive 3D stacking complexity.
This approach lowers manufacturing risk and costs while creating modular upgrade paths for end devices—advantages missing in monolithic or 3D-stacked designs.
These points echo constraints shifts seen in other hardware bets, such as Microsoft-backed Veir's superconductor shift, where system design reimagines fundamental limits.
Why This Matters for Device Makers and Data Center Operators
At scale, a >50% power cut in chips can translate into billions saved in data center energy costs annually.
This removes the barrier of escalating electricity and cooling expenses that now limit data center expansion and mobile device battery life.
Device manufacturers gain durable competition advantages by embedding chiplets that extend runtime and reduce heat without costly redesigns.
PowerLattice’s chiplet mechanism automates this efficiency into hardware, working continuously without extra operational overhead—a hallmark of leverage that shifts economic ceilings without constant human intervention.
Businesses must pay attention as this system-level power rethink aligns with broader trends in AI infrastructure and edge computing efficiency demands.
