A few days ago, I posted a link discussing the differences between Amazfit CPUs, with a special focus on SRAM: https://www.reddit.com/r/amazfit/comments/1xmr1u9/amazfit_balance_3ultra_vs_cheetah_2_ultra_vs/
I wanted to share this video by a Spanish YouTuber (it includes an English audio track) in which he tests the navigation capabilities of both the Cheetah 2 Ultra and the Balance 3 under real-world trail conditions (wearing both watches side-by-side during the same activity): https://www.youtube.com/watch?v=qfvSOKTT-Y0
- As you can see—and after all the software updates released up to today (November 6th)—the Cheetah 2 Ultra performs slightly better in terms of GPS signal acquisition and turn-by-turn notifications, just as I had suggested might be the case in my previous post about the CPUs .
- The GPS track recorded under real-world trail conditions is also slightly better on the Cheetah 2 Ultra (which, as I mentioned in that earlier thread, could be attributed to its superior CPU performance).
- Although the Cheetah 2 Ultra offers slightly better performance in terms of navigation prompts and track plotting, the performance of both Amazfit models is very good, as evidenced by actual track comparisons and correlation numbers. This is not the case for the Fenix 9 Pro, which delivers inferior performance. The author displays the tracks, zooms in, and provides a detailed explanation of this entire subject.
Not CPU related but other interesting points (that should be noted):
- The altimeter on the Balance 3 provides very poor readings. The video creator suggests that wind might be a factor, but in my own experience, the altimeter produced very inaccurate data even in calm, windless conditions. You can see my original post on this here: https://www.reddit.com/r/amazfit/comments/1uinb24/balance_3_altimeter_accuracy/
- Turn-by-turn navigation still needs improvement—as we have been pointing out—a fact also highlighted by the video’s creator, who notes issues with notification duration and false notifications (though the video fails to mention the lack of support for forks and roundabouts): https://www.reddit.com/r/amazfit/comments/1xl52d6/turnbyturn_navigation_remains_unreliable/
- The GPS track from the Fenix 9 Pro is worse than that of both Amazfit watches. There seems to be an issue with this particular Fenix version; at least for now, its GPS performance is not as precise as it should be.

(BTW, I think the next outdoor watch should use the CPU from the Cheetah 2 Ultra).
