Garmin Forerunner 965 has an AMOLED display. Forerunner 945 continues to use the MIP or memory-in-pixel screen.

The difference between AMOLED and MIP display technology is very significant.

  • The display resolution of Garmin Forerunner 965 is 454 x 454 pixels and the display resolution of Forerunner 945 is 240 x 2402 pixels only. The difference in the display resolution can be directly attributed to the AMOLED display type of Forerunner 965.

  • Additionally, the Forerunner 965 has an ambient light sensor.

Both watches do have a color display.

The only downside to AMOLED display and Always-on-display mode is heavier battery usage.

From the perspective of display specifications, Forerunner 965 is definitely ahead of the Forerunner 945.

One of the biggest differentiators between the Forerunner 965 and 945 has to be the availability of a multi-frequency positioning sensor on the Forerunner 965.

Multi-frequency positioning sensor helps in offering multi-band GPS support on Forerunner 965. With multi-band GPS, you can get GPS data from multiple satellites at the same time. This improves the accuracy of GPS data to a great extent.

Besides the multi-band GPS, the SatIQ technology on Forerunner 965 is another big differentiator. SatIQ helps in toggling between multi-band or single GPS modes automatically. If the quality of GPS data is good, SatIQ will not use the multi-band GPS feature as it causes severe battery drain.

The chief benefit of SatIQ technology is the conservation of battery life.

For serious runners, Forerunner 965 should be preferred on account of multi-band GPS support.

Activity profiles

There are incidental differences between Forerunner 965 and 945 in terms of various activity profiles offered.

Forerunner 965 offers additional profiles for outdoor recreation, cycling, swimming, running, and Gym. Not all people may need these. However, for elite runners, it may be worth checking the actual profiles offers on Forerunner 965 in comparison with Forerunner 945.

  • Gym profiles – Forerunner 965 has additional profiles for HIIT workouts and offers on-screen workout muscle maps.
