Did Garmin upgrade the heart rate sensor on the Fenix 9 or Fenix 9 Pro?

No. Both use the same Elevate Gen 5 sensor as the Fenix 8 and Fenix 8 Pro, confirmed on Garmin’s own spec sheet.

Is the GPS chip different on the Fenix 9?

No confirmed difference. Garmin lists the same dual-frequency GPS across five satellite systems as the Fenix 8. Whether the physical chip changed is unconfirmed pending a teardown.

Does the Fenix 9 Pro have a faster chip than the standard Fenix 9?

Yes, confirmed by Garmin via DC Rainmaker. Both likely share the same new chip family at different speeds, but a teardown hasn’t confirmed that detail.

Which Fenix 9 model got a new screen?

Only the 51mm Fenix 9 Pro changed size and sharpness. Every other size kept its existing dimensions, just brighter.

Does the titanium case affect GPS or satellite signal?

Unknown. Fully metal cases have historically needed a special gap for signals to pass through. Garmin hasn’t addressed this for the Fenix 9 Pro, and no reviewer has tested it yet.
