- Maps: The Forerunner 965 includes full onboard topographic maps. The 570 does not offer mapping at all.
- Speaker + Mic: The 570 adds a built-in speaker and microphone for phone calls, voice assistant, and more—this feature is missing on the 965.
- Sizes: The 965 is only available in a 47mm size, while the 570 is available in both 42mm and 47mm versions—great if you want a smaller watch.
- Elevate 5 HR Sensor: The Forerunner 570 features Garmin’s latest Elevate Gen 5 optical heart rate sensor, which offers improved accuracy and the addition of skin temperature tracking. However, it is the only watch in Garmin’s lineup that has the Gen 5 sensor but does not offer ECG readings. The 965 uses the older Gen 4 sensor and lacks ECG and temperature-based insights.
