According to the Bluetooth SIG product database page, Apple has submitted a list called “WatchOS Profile Subsystem 2023”, indicating that it is preparing for the launch of the Apple Watch in September.
The list does not disclose any information, Note: Apple’s current Apple Watch Series 8, Apple Watch SE and Apple Watch Ultra all support Bluetooth 5.3.
In a recent Power On newsletter, Bloomberg’s Mark Gurman says the S9 will offer the first “significant speed improvements” since the Series 6.
Apple has 1GB of RAM in the Apple Watch Series 4 and 1.5GB of RAM in the Series 6 through Series 8. The A15 uses the same LPDDR 4x specification memory as the A13, and it is currently unclear whether Apple will increase the memory.
The biggest change from the A13 upgrade to the A15 lies in the production process. The A15 is manufactured using TSMC’s second-generation 5nm process – N5P.
Based on the performance difference between A13 (7nm) and A15 (5nm), the media speculates that the performance of the S9 chip can be increased by 40-50%, and the power consumption can be reduced by 30%.
