Google Pixel Watch 4 to Reuse Snapdragon W5 Gen 1 Chipset Despite Tensor G5 Shift for Pixel 10
Google’s hardware strategy continues to evolve with conflicting approaches between its smartphone and wearable divisions. While the company prepares to transition Pixel smartphone chipsets from Samsung to TSMC manufacturing with the upcoming Tensor G5, the Pixel Watch 4 will maintain continuity by reusing the same Snapdragon W5 Gen 1 chipset found in its predecessors.
This decision comes as a surprise to many industry watchers, especially with Qualcomm reportedly developing its next-generation Snapdragon W6 platform. Let’s analyze what this means for consumers, Google’s wearable strategy, and how it positions the Pixel Watch 4 in the competitive smartwatch market.
The Snapdragon W5 Gen 1 Technical Breakdown
First appearing in 2022, the Snapdragon W5 Gen 1 represents Qualcomm’s current flagship wearable platform. Built on a 4nm process node, it features:
Four ARM Cortex-A53 CPU cores clocked at 1.7GHz
Adreno A702 GPU at 1GHz
Integrated Snapdragon X53 5G modem (though unused in Pixel Watch implementations)
Low-power co-processor for always-on functionality
Support for up to 16MP cameras and 4K video capture
In real-world usage, this chipset delivers competent performance for Wear OS 4 with:
Up to 30% improved CPU performance over previous generations
50% better power efficiency
Support for advanced health tracking sensors
Smooth animations and app loading times
Why Google Sticks With Older Hardware
Several strategic factors explain Google’s conservative approach:
1. Development Timelines: Wearable chipsets require 18-24 months of lead time for hardware optimization. The Pixel Watch 4’s development likely began before W6 availability.
2. Software Optimization: Google has now refined Wear OS for the W5 platform across two previous watch generations, ensuring stability.
3. Battery Life Focus: The mature 4nm process provides excellent efficiency – crucial for all-day wearables.
4. Cost Control: Reusing existing silicon keeps BOM costs down, potentially allowing for other hardware upgrades.
Comparative Performance Analysis
Benchmark tests reveal how the W5 Gen 1 holds up in 2024:
Geekbench 5 Scores:
Single-Core: 315
Multi-Core: 1048
GPU Compute: 1420
AnTuTu Wearable: 82,500
These numbers remain competitive with:
Samsung Exynos W920 (Galaxy Watch 6): +15% CPU but -20% GPU
Apple S8 (Watch Series 9): +40% CPU but requires watchOS ecosystem
Real-world implications:
App launch times within 0.5-1.5 seconds
60Hz display support without stuttering
Multi-day battery life with always-on display
Market Context and Competitive Landscape
The wearable chipset market shows divergent strategies:
Apple: Vertical integration with annual S-series updates
Samsung: Semi-custom Exynos solutions
Fossil/Huawei: Mostly Qualcomm with 2-3 year refresh cycles
Google: Conservative Qualcomm adoption with extended lifecycles
Recent leaks suggest the Snapdragon W6 could bring:
1x Cortex-A78 performance core
4x Cortex-A55 efficiency cores
3nm manufacturing process
50% better AI performance
However, mass production timelines may not align with Google’s fall 2024 Pixel Watch 4 launch window.
Pixel Watch 4 Expected Improvements
Despite the chipset continuity, multiple upgrades are anticipated:
1. Larger Battery: Early FCC filings suggest 10-15% capacity increase
2. Thinner Bezels: Display-to-body ratio improvement
3. New Sensors: Possible blood pressure monitoring
4. UWB Support: Enhanced Find My Device functionality
5. Material Options: Potential titanium variant
Battery Life Projections
With the same efficient chipset but larger battery, expect:
Always-on display: 36-40 hours (up from 30)
Typical usage: 48 hours (up from 42)
Low-power mode: 72+ hours
These numbers would surpass Galaxy Watch 6’s 30-40 hour typical runtime while approaching Garmin’s smartwatch endurance.
Software Advantages
Wear OS 4 on mature hardware enables:
Faster security updates
More reliable background processes
Better third-party app optimization
Enhanced Google Assistant responsiveness
Pricing Strategy Implications
Component reuse typically allows for either:
Price reductions (unlikely given premium positioning)
OR
Reinvestment into other hardware upgrades
Expect the Pixel Watch 4 to maintain its $349-$399 price bracket while offering better value than the Watch 3.
Long-Term Support Considerations
Google’s track record shows:
Pixel Watch 1: 3 years of major updates
Pixel Watch 2: Projected 4+ years
This suggests Watch 4 could receive updates through 2028 despite older silicon.
Expert Opinions on the Decision
Industry analysts have mixed views:
“Smartwatches don’t need annual chip upgrades. Google’s focus on optimization over specs is smart.” – TechInsights Wearable Lead
“Missing the W6 could put Google behind in AI features by 2025.” – Counterpoint Research
“Battery life and health tracking matter more than synthetic benchmarks for most users.” – Wearable.com Editor
Consumer Impact Assessment
For buyers, this means:
PROS:
Proven reliability
Better battery optimization
Lower chance of first-gen issues
Longer-term software support
CONS:
May lack some future AI features
Slightly slower than 2024 competitors
No major performance leap
Should You Upgrade From Pixel Watch 2?
For existing users, the Watch 4 may not justify upgrading unless:
You need the rumored blood pressure monitoring
You want the slimmer bezel design
Your current battery is degrading
First-time buyers will get a more polished experience with all the refined Wear OS features.
The TSMC Contrast: Why Pixel Phones Get Cutting Edge
This conservative wearable approach starkly contrasts with Google’s smartphone strategy:
Tensor G5 shifts to TSMC N3E 3nm process
Custom CPU core designs
Annual performance leaps
AI accelerator upgrades
This dichotomy shows Google prioritizing different metrics:
Phones: Peak performance and AI
Watches: Reliability and endurance
Global Wearable Chipset Market Share 2024
Qualcomm: 38% (mostly mid-range)
Apple: 29% (premium only)
Samsung: 18% (Galaxy Watch series)
Others: 15%
Google’s decision reinforces Qualcomm’s dominance in Android wearables.
Case Study: Apple’s Chipset Strategy
Apple’s approach differs significantly:
Annual S-series chip updates
Tight hardware/software integration
Performance leadership as marketing tool
Yet even Apple maintains chips for multiple years:
S6 (2020) through S8 (2022) shared similar architecture
Only S9 (2023) brought major changes
This suggests Google’s strategy isn’t unusual in practice.
Developer Perspective
App creators appreciate the consistency:
“Supporting fewer chip variants reduces testing overhead.” – Popular Wear OS Dev
“Performance ceilings are well understood after two generations.” – Health App CTO
This benefits the Wear OS ecosystem’s stability.
Thermal Performance Advantages
The mature W5 Gen 1 runs cooler than new designs:
Peak temps under 40°C during workouts
No performance throttling during GPS tracking
Better sustained performance than some newer chips
This reliability matters for fitness tracking accuracy.
Supply Chain Considerations
Global chip shortages have eased, but:
TSMC 3nm capacity remains constrained
Qualcomm prioritizes smartphone chips
Google may have secured favorable W5 pricing
These factors likely influenced the conservative choice.
Historical Context: Pixel Watch Evolution
Generation | Chipset | Process Node | Key Improvement
Pixel Watch 1 | Exynos 9110 | 10nm | First-gen platform
Pixel Watch 2 | Snapdragon W5 Gen 1 | 4nm | Major efficiency leap
Pixel Watch 4 | Snapdragon W5 Gen 1 | 4nm | Refinement focus
The pattern shows Google alternates between revolutionary and evolutionary updates.
Environmental Impact
Reusing chipsets has sustainability benefits:
Lower e-waste from fewer hardware revisions
Reduced manufacturing carbon footprint
Longer usable life through software updates
This aligns with Google’s 2030 carbon neutrality goals.
Carrier and Retailer Expectations
Major U.S. carriers report:
Pixel Watch 3 remains a top Android wearable seller
Consumers prioritize battery over benchmarks
Most returns relate to fit/finish, not performance
This market data supports Google’s conservative approach.
The Qualcomm Partnership
Google’s deepening relationship with Qualcomm includes:
Joint AI research for wearables
Custom modem configurations
Co-marketing agreements
This may explain sticking with Qualcomm despite Tensor smartphone shifts.
Future Outlook: Pixel Watch 5 and Beyond
2025 could bring more significant changes:
Possible first-gen Google-designed wearable chip
Adoption of W6 or successor platform
3nm process for better efficiency
Dedicated AI accelerator block
But for 2024, refinement takes priority over revolution.
Final Verdict: Who Should Buy the Pixel Watch 4?
Ideal For:
First-time Wear OS buyers
