Galaxy Watch 9 Drops Exynos for Snapdragon Wear Elite

Foundry Difference: Samsung vs. TSMC

Both the old Exynos W1000 and the new Snapdragon Wear Elite are built on a 3 nm process node, but they come from different foundries — and that distinction matters for real-world performance and efficiency .

• Exynos W1000 (Galaxy Watch 7, 8, Ultra): Fabricated by Samsung Foundry on its 3nm GAA (Gate-All-Around) process .
• Snapdragon Wear Elite (Galaxy Watch 9, Ultra 2): Fabricated by TSMC on its 3nm process .

TSMC's 3nm node is widely regarded as more mature, delivering better yield and efficiency than Samsung's competing node . This is the same reason Qualcomm shifted flagship Snapdragon smartphone chip production from Samsung to TSMC in recent years . The move to TSMC is a key enabler of the Wear Elite's performance-per-watt gains .

Performance Improvements: The First big.LITTLE Wearable CPU

The Snapdragon Wear Elite introduces Qualcomm's first big.LITTLE architecture for wearables :

• 1 high-performance core at 2.1 GHz + 4 efficiency cores at 1.95 GHz .
• CPU: Up to 5x faster single-core performance vs. the previous Snapdragon W5+ Gen 2 wearable chip .
• GPU: Up to 7x improvement in max FPS, capable of rendering 1080p video at 60fps .
• Real-world speed: Leaked Geekbench results suggest roughly 50% faster than the Exynos W1000 in the Galaxy Watch 8 .

The chip also supports up to 32 GB of eMMC storage, a significant bump for storing music, maps, and apps locally .

On-Device AI: The Dedicated NPU Changes Everything

This is the most transformative upgrade in the new chip. The Exynos W1000 lacks a dedicated NPU, meaning all Gemini AI queries had to be relayed to a paired phone, which introduced latency and required a constant connection .

The Snapdragon Wear Elite eliminates that bottleneck entirely :

• Main Hexagon NPU: Runs AI models of up to 2 billion parameters locally at a measured 10 tokens per second — fully independent of the phone .
• Second low-power embedded NPU (eNPU): Handles always-on background tasks — keyword detection, activity recognition — without waking the main NPU .
• AI compute: Qualcomm rates the combined NPU performance at up to 12 TOPS (trillion operations per second) . (Some sources cite 10 TOPS .)
• Leaked Galaxy AI features enabled by this hardware include on-watch Gemini wrist-raise activation, new AI Tiles for health and productivity, smart replies, content-aware recommendations, and new health tools .

Battery Life & Charging

• Battery life: Qualcomm claims 30% longer runtime compared to the prior Snapdragon Wear generation . The 44mm Galaxy Watch 9 has a leaked rated battery of 435 mAh, a modest ~2.5% increase over the Watch 8's 425 mAh . The real endurance gains will come from the chip's 30% better power efficiency, not a larger battery .
• Charging: Supports significantly faster charging — up to 50% charge from flat in approximately 10 minutes, with a full charge at 10W taking roughly 1 hour and 10-20 minutes .

Connectivity: 5G, Wi-Fi 6E, and UWB

The Snapdragon Wear Elite is a connectivity powerhouse :

• 5G: The first Galaxy Watch to offer cellular connectivity on 5G networks .
• Bluetooth 6.0 (up from 5.3 in previous models) .
• Wi-Fi 6/6E for faster local streaming and downloads .
• UWB (Ultra-Wideband): For precise location tracking and enhanced compatibility with other UWB-enabled devices like Samsung SmartTags and digital car keys .
• Satellite messaging support is also included .

Will Both Galaxy Watch 9 and Ultra 2 Get the Chip?

The picture is slightly mixed. Samsung confirmed at MWC 2026 that its upcoming Galaxy Watch lineup will run the Snapdragon Wear Elite platform . Most leaks indicate both the Galaxy Watch 9 and Galaxy Watch Ultra 2 will use the same Snapdragon Wear Elite chip .

However, one prominent leak from TechDailyCare in early July suggests that for the first time, the standard and Ultra models may run on different chips: the Galaxy Watch 9 retaining the Exynos W1000, while only the Watch Ultra 2 gets the Snapdragon Wear Elite . This remains unconfirmed and contradicts other recent leaks .

What Else Is Expected at Galaxy Unpacked (July 22)

The event is confirmed for July 22 in London at 9 a.m. ET / 2 p.m. BST, with a livestream on Samsung.com . Expected product launches include :

• Galaxy Z Fold 8 — reportedly a wider, shorter book-style design to better compete with foldables from competitors .
• Galaxy Z Fold 8 Ultra — a new ultra-premium foldable variant with upgraded cameras, displays, and a larger 5,000 mAh battery .
• Galaxy Z Flip 8 — the latest clamshell foldable .
• Galaxy Watch 9 (standard 40mm and 44mm sizes) .
• Galaxy Watch Ultra 2 (second-generation rugged model) .
• One UI 9 / Galaxy AI software updates .
• Galaxy XR Glasses — Samsung and Google's Android XR smart glasses, possible but not yet confirmed .

Bottom line: The Snapdragon Wear Elite switch is the most consequential hardware change in Galaxy Watch history. It moves AI processing entirely on-device, roughly doubles or triples raw compute headroom, improves battery life by roughly 30%, and adds 5G/UWB connectivity — all while pivoting from Samsung's own foundry to a TSMC 3nm process that delivers better efficiency. The full official reveal happens July 22 at Unpacked.
