These two Garmins look almost identical on the wrist and share the same 47mm case, the same 16-day smartwatch battery, and the same multi-band GPS. But they were built a year apart and target slightly different buyers. Here is where they actually split.
Key Differences
- ECG: The Epix Pro Gen 2 has an ECG sensor for on-wrist heart-rhythm checks. The Fenix 8 AMOLED does not.
- Diving: The Fenix 8 AMOLED adds a depth sensor and is built for dive tracking. The Epix Pro has no depth sensor.
- Screen: The Fenix 8 uses a larger 1.4-inch AMOLED panel at 454 x 454 pixels. The Epix Pro is 1.3-inch at 416 x 416.
- Price: The Epix Pro Gen 2 launched at $999.99, a clean $100 under the Fenix 8 AMOLED at $1,099.99.
- Build: The Epix Pro has a titanium bezel and rear cover. The Fenix 8 uses a polymer bezel with a titanium rear cover only.
Deep Dive Comparison
Design & Comfort
Both watches are 47mm and built from fiber-reinforced polymer, so they wear the same on a normal wrist. The Epix Pro Gen 2 is a touch lighter at 70g versus 73g for the Fenix 8, and it wraps its bezel in titanium instead of polymer, which reads a little more premium up close. The Fenix 8 counters with a slightly bigger, higher-resolution display that is easier to read at a glance during a run. Both carry a 10 ATM water rating, but only the Fenix 8 has the depth sensor to make that rating useful underwater.
Battery Life
In everyday smartwatch mode they are a dead heat: 384 hours, or 16 days, each. The only real gap shows up with GPS running. The Fenix 8 AMOLED holds on for 47 hours of multi-band GPS versus 42 hours on the Epix Pro Gen 2. That 5-hour edge matters if you do ultra-distance events, but for a weekend long run neither watch will blink.
Health & Fitness Features
Both watches share Garmin’s core stack: optical heart rate, Pulse Ox blood oxygen, a barometric altimeter, compass, and thermometer, all feeding the same excellent training and recovery metrics. The split is at the edges. The Epix Pro Gen 2 adds an ECG sensor for heart-rhythm spot checks, which the Fenix 8 lacks. The Fenix 8 goes the other direction with a depth sensor for diving and an ambient light sensor. Both use multi-band GPS, so real-world tracking accuracy between them is a wash.
Smart Features
This category is a tie. Both have a built-in microphone and speaker for calls and voice control, NFC for Garmin Pay, 32GB of storage for offline music, and the same Bluetooth, ANT+, and Wi-Fi connectivity. Whatever you can do on one, you can do on the other.
Price & Value
The Epix Pro Gen 2 launched at $999.99 and, as the older model, tends to sell for less on the street than the $1,099.99 Fenix 8 AMOLED. For most buyers you are paying the $100 premium on the Fenix 8 for the depth sensor, the bigger screen, and the newer hardware. If none of those move you, the Epix Pro is the smarter spend and throws in ECG on top.

The Verdict
Buy the Garmin Fenix 8 AMOLED if you dive or want the newest hardware. The depth sensor, the larger and sharper 1.4-inch screen, and the extra 5 hours of GPS battery are real, and they justify the $1,099.99 price for that buyer. It is the more capable watch.
Buy the Garmin Epix Pro Gen 2 if you want the most watch for your money. You get the same 16-day battery, the same multi-band GPS, a lighter full-titanium bezel, and an ECG sensor the Fenix 8 does not have, all for $100 less. Unless you are getting in the water, the Epix Pro is the smarter buy for most people.
Frequently Asked Questions
Which watch should most people buy?
For most buyers, the Epix Pro Gen 2 is the better value. It matches the Fenix 8 on battery, GPS, and smart features, adds an ECG sensor, and costs $100 less. Only choose the Fenix 8 if you specifically need the depth sensor for diving or want the larger, sharper screen.
Does the Garmin Fenix 8 AMOLED have ECG?
No. Per the specs, the Fenix 8 AMOLED does not include an ECG sensor, while the Epix Pro Gen 2 does. If on-wrist heart-rhythm checks matter to you, the Epix Pro is the one to get.
Is the Fenix 8 AMOLED worth the extra $100?
Only if you use the features it adds. The depth sensor for diving, the bigger 1.4-inch display, and 5 more hours of GPS battery are the whole premium. If you never dive and do not care about screen size, that $100 buys you very little over the Epix Pro Gen 2.
Which is better for a triathlete or ultra runner?
Both use the same multi-band GPS and 16-day smartwatch battery, so tracking quality is identical. The Fenix 8 edges ahead with 47 hours of GPS battery versus 42, which only matters for very long events. For a triathlete who also does open-water or dive work, the Fenix 8’s depth sensor tips it further.
Do both watches work with iPhone and Android?
Yes. Both connect over Bluetooth, ANT+, and Wi-Fi and pair with the Garmin Connect app on either iPhone or Android. Music storage, NFC payments, and call handling through the built-in mic and speaker work the same on both platforms.
