Amazfit GTR 4 vs Garmin Fenix 8 AMOLED 47mm
Side-by-side specifications, scores and verdict.
Quick Verdict
Amazfit GTR 4 excels as an affordable daily wear smartwatch with its lightweight 34g design, vibrant 1.43-inch AMOLED display, and exceptional 14-day battery life in normal mode. Garmin Fenix 8 AMOLED targets serious athletes and adventurers with premium titanium construction, comprehensive health monitoring (ECG, skin temperature), dive-rated 10 ATM water resistance, and superior durability despite being significantly heavier at 73g. Performance differs notably: GTR 4's Zepp OS handles basic fitness tracking and notifications smoothly, while Fenix 8's Garmin OS provides advanced training metrics, navigation, and multisport capabilities. Battery longevity favors GTR 4 in everyday use, but Fenix 8 manages impressive 42-hour GPS endurance for expeditions. Health tracking is GTR 4's limitation—missing ECG and skin temperature sensors present in Fenix 8. For casual fitness enthusiasts prioritizing value and daily convenience, GTR 4 delivers excellent features at under $200. Athletes requiring professional-grade monitoring and extreme durability should invest in Fenix 8, despite the $900 premium. Choose GTR 4 for budget-conscious users; select Fenix 8 for serious outdoor enthusiasts.
