Google Shifts Tensor G5 Chip Production to TSMC
A Silent Shift That Sent Shockwaves Through the Chip Industry
In the hyper-competitive world of semiconductor manufacturing, a single decision by a major technology company can reshape alliances, expose weaknesses, and redefine the balance of power. Google’s recent move to shift production of its upcoming Tensor G5 chipset from Samsung Foundry to TSMC’s advanced 3nm process is one such decision—quiet in announcement, but massive in impact.
For years, Samsung had been Google’s exclusive manufacturing partner for Tensor chips, powering Pixel smartphones since 2021. That partnership symbolized trust, collaboration, and shared ambition. But with Tensor G5, Google has chosen a different path—one that prioritizes efficiency, reliability, and long-term performance leadership over legacy relationships.
This move has not only resulted in a major account loss for Samsung, but it has also triggered internal investigations, raised questions about yield stability, and highlighted a growing performance gap between the world’s two most powerful chip foundries.
More importantly, this shift marks a turning point for Google itself. Tensor G5 is not just another chip—it is the company’s first fully in-house designed system-on-chip, codenamed “Laguna”, built to push AI-driven experiences further than ever before.
Let’s explore why Google made this move, what it means for Samsung and TSMC, and how it could shape the future of smartphones and silicon manufacturing through the end of this decade.
The End of an Era: Google and Samsung’s Tensor Partnership
When Google introduced the first Tensor chip in 2021, it marked a strategic shift away from off-the-shelf processors toward custom silicon optimized for Google’s software and AI vision. Samsung Foundry was chosen as the manufacturing partner, leveraging its close ties with Google and its experience producing advanced mobile chips.
From Tensor G1 to Tensor G4, Samsung handled fabrication duties. However, these chips often faced criticism for:
- Thermal inefficiency
- Power consumption issues
- Inconsistent performance under sustained workloads
While Google continuously refined its designs, manufacturing limitations increasingly became a bottleneck—especially as AI workloads grew heavier and user expectations climbed higher.
Tensor G5 represents Google’s moment to reset the foundation.
Why TSMC? The Yield and Reliability Advantage
At the heart of Google’s decision lies one critical factor: manufacturing maturity.
Yield Rates Tell the Real Story
- Samsung 3nm yield: ~50%
- TSMC 3nm yield: ~90%
In semiconductor manufacturing, yield is everything. A lower yield means:
- Higher costs
- Fewer usable chips
- Inconsistent performance
- Supply chain instability
For a company like Google—shipping millions of Pixel devices globally—this level of uncertainty is unacceptable.
TSMC’s significantly higher yields offer Google:
- Predictable production volumes
- Consistent chip quality
- Better thermal and power characteristics
This reliability becomes even more critical when the chip is designed entirely in-house and tightly integrated with software.
Process Superiority: Why TSMC’s 3nm Matters
TSMC’s 3nm process is currently considered the most refined and production-ready advanced node in the industry. Compared to Samsung’s equivalent process, it offers:
- Improved energy efficiency
- Better thermal stability
- Higher transistor performance consistency
For Tensor G5, this matters deeply because the chip is designed around AI-heavy workloads, including:
- On-device generative AI
- Advanced computational photography
- Real-time language processing
- Security and privacy-focused AI models
These tasks demand sustained performance without overheating or battery drain—an area where TSMC excels.
Tensor G5 “Laguna”: Google’s First Fully Custom Silicon
Perhaps the most important aspect of this transition is what Tensor G5 represents internally at Google.
Unlike previous Tensor chips that relied partly on third-party IP blocks, Tensor G5 is fully custom, integrating:
- A bespoke Image Signal Processor (ISP)
- A custom Tensor Processing Unit (TPU)
- Google-designed memory and controller IP
- Deep software-hardware co-optimization
This level of customization requires absolute confidence in the manufacturing partner. Even small inconsistencies in fabrication can break performance targets or reduce efficiency.
TSMC’s proven track record with fully custom chips for companies like Apple made it the natural choice.
A Long-Term Bet: Google and TSMC Through Pixel 14
This is not a one-off decision.
Reports indicate that Google’s agreement with TSMC is expected to run through Pixel 14, potentially extending until 2030. This signals:
- A deep, multi-year strategic partnership
- Long-term confidence in TSMC’s roadmap
- Google’s commitment to custom silicon as a core differentiator
Such long-term contracts are rare and valuable in the foundry world—and losing one is a serious blow.
Samsung’s Reaction: Internal Reviews and Foundry Soul-Searching
The loss of Google as a Tensor manufacturing partner has reportedly sent shockwaves through Samsung.
Immediate Consequences for Samsung Foundry
- Loss of a high-profile global client
- Reduced credibility in advanced node competition
- Pressure from investors and internal leadership
Samsung has initiated:
- An internal investigation
- A broader review of its 4nm and 3nm processes
- Strategic assessments of yield, timelines, and tooling
While Samsung remains a semiconductor giant, this event exposes critical vulnerabilities in its foundry business—particularly as competitors accelerate.
Broader Industry Impact: A Clear Signal to the Market
Google’s move does not happen in isolation. It sends a strong signal to the entire semiconductor ecosystem.
Key Industry Takeaways
- TSMC’s lead is widening, not shrinking
- Advanced node success depends on execution, not announcements
- Custom silicon demands absolute manufacturing excellence
- Foundry credibility is increasingly fragile
For other companies considering in-house chip designs, Google’s decision reinforces one message: manufacturing reliability matters more than loyalty.
What This Means for Pixel Smartphones
For consumers, the implications are significant.
Future Pixel devices powered by Tensor G5 and beyond are expected to deliver:
- Better battery life
- Improved sustained performance
- Cooler thermals during heavy use
- More powerful on-device AI features
This could finally address long-standing criticisms of Pixel hardware while strengthening Google’s position against Apple and Qualcomm-powered Android rivals.
TSMC vs Samsung: The Foundry Battle Intensifies
The semiconductor race is no longer just about who reaches the smallest node first—it’s about who can deliver it at scale, with consistency.
TSMC currently leads in:
- Yield maturity
- Client trust
- Advanced process stability
Samsung still has immense resources, talent, and ambition—but the road back to parity will require execution, not promises.
A Defining Moment for Silicon Strategy
Google’s shift of Tensor G5 production to TSMC is more than a manufacturing change—it’s a declaration of intent.
It reflects:
- Google’s seriousness about custom silicon
- The growing importance of AI-optimized hardware
- The unforgiving nature of advanced chip fabrication
For Samsung, it is a wake-up call.
For TSMC, it is validation.
For the industry, it is a reminder that leadership in semiconductors is earned every single wafer.
As Pixel devices evolve and AI becomes central to everyday computing, decisions like this will shape not just smartphones—but the future of technology itself.
