Apple Watch Series 10 vs 8 and earlier
Processor, GPU, Neural Engine, storage
Series 10 is powered by the new S10 SiP. Apple didn’t share any details on exactly how much faster it is compared to S9, S8, and earlier. But it says it was custom-designed for “performance, power efficiency, and intelligence.”
During its unveiling, Apple suggested the S10 will deliver better experiences with machine learning tasks, on-device Siri, health features, and capabilities like Apple Watch double tap control.
| Series 10 | Series 8 | |
| SiP/processor | S10 SiP 64-bit dual-core processor | S8 SiP 64-bit dual-core processor |
| Neural Engine | 4-core | ❌ |
| Ultra wideband chip | ✅ – gen 2 | ✅ – gen 1 |
| Bluetooth | 5.3 | 5.3 |
| Storage | 64GB | 32GB |
If you’re coming from Series 8 you might not notice a big difference in speed and capability, but it should be smoother and a bit faster overall.
Two more benefits, compared to Apple Watch 8 or earlier, you get an increase in storage to 64GB and the ultra wideband gen 2 chip with Series 10 which offers precision finding.
Case and display
Apple Watch Series 10 introduces new sizes for the wearable that feature the biggest displays and thinnest design.
The 46 and 42mm cases offer what Apple says is up to 30% more screen area compared to Series 6. That means you get an additional line of text on the display and for the 46mm Series 10, a display that is ever-so-slightly larger than even the 49mm Apple Watch Ultra/2.
Both the display and case of Series 10 have more rounded corners that give a softer and sleeker feel. Interestingly, Apple did increase the bezel of the display slightly with Series 10.
For thickness, Apple says Series 10 is almost 10% thinner than Series 7, 8, and 9.
And you’re getting a 2x brighter screen with Series 10 vs 8.
Another new feature is the wide-angle OLED display that delivers up to a 40% brighter screen when looking from an angle.
| Series 10 | Series 8 | |
| Case size | 46/42mm | 45/41mm |
| Display size | 416 x 496 pixels, 1220 sq mm (46mm model) | 396 x 484 pixels, 1143 sq mm (45mm model) |
| Brightness max | 2,000 nits | 1,000 nits |
| Always-on display | ✅ | ✅ |
| Wide-angle OLED display | ✅ | ❌ |
| Sapphire crystal front | With titanium models | With steel models |
| Ion-X front | With aluminum models | With aluminum models |
Apple Watch band compatibility
Apple highlights “You can match most bands with any Apple Watch Series 3 or later case of the same size.”
Battery life and charging
Apple has improved charging with Series 10. It can go from 0-80% in just 30 minutes. That’s compared to 45 minutes for the same with Series 8.
Battery life remains the same at up to 18 hours with standard mode and up to 36 hours with Low Power mode.
| Series 10 | Series 8 | |
| Battery life – standard | 18 hours | 18 hours |
| Extended battery with Low Power mode | 36 hours | 36 hours |
| Charging | 0-80% in 30 minutes | 0-80% in 45 minutes |
If you’re interested in using Apple Watch Series 10 for sleep tracking, you also get 8 hours worth of use from an 8-minute charge (same as Series 8 and 9).
Apple Watch 10 vs 8 – Key features
New with Apple Watch Series 10 are Sleep apnea notifications (although this will arrive for Series 9 and Ultra 2 with an update).
You also can play audio directly through the wearable’s speaker, and Series 10 gains features from the Ultra 2 – the water depth gauge and water temperature sensor.
Like with Series 9 and Ultra 2, the Blood Oxygen feature is not available in the US for Series 10. So that’s something you’ll lose when coming from Series 8.
