The new Apple Watch Series 4 features a new Apple S4 processor, which is 64-bit, and smashes the Apple Watch Series 3 and older, as found by an earlier speed test. The Apple Watch Series 4’s monstrous processor is a major update, which has 64-bit technology. 64-bit was first introduced in the iPhone with the launch of iPhone 5s in 2013 with the Apple A7 processor which allowed features like Touch ID and iOS 7 software, featuring full 64-bit compatibility.
The new Apple Watch Series 4 claims to offer very similar performance to an iPhone 6s, and that is a fast phone. It is unbelievable how a device so small offers similar performance to an iPhone 6s, featuring an Apple A9 processor and 2GB of RAM, running full iOS 12 software.
Apple says the new 64-bit S4 processor is up to 2x faster than the Apple S3 processor powering the Apple Watch Series 4. Apple developer Steve Troughton-Smith claims that the new Apple Watch Series 4 can play 60fps animations on Apple’s Metal API, which allows GPU’s to tap into the power of Metal.
This is a big step forward for Apple. They could power a new iPhone with an S-series processor, which is a lot smaller.
