Apple Watch Ultra 4 has the same external look as Ultra 3, but it’s packed with internal upgrades to the chip and health sensors that unlock new and improved features. Here’s everything new in Apple Watch Ultra 4 vs Ultra 3.
Performance: S11 chip and 4GB RAM
Apple often includes a new chip with its latest Watch models, but most chip updates include only minor changes and minimal performance gains. And last year, Apple opted to stick with the same S10 from 2024.
But Apple Watch Ultra 4 has a brand-new S11 chip. S11 unlocks exclusive new software features thanks to its more powerful capabilities.
Apple doesn’t give specific benchmarks to measure the improvements, only saying S11 is its “most powerful wearable chip.”
