A15 of the Apple iPhone 13 compared to the battery of the A14 processor of the iPhone 12 and performance improvements
As a rule of thumb, these second generation tapeouts will further refine the gains made with the first generation, as was the case with the 7nm process, rather than introducing some jaw-dropping technology leaps that become increasingly difficult with each shrinking of the production node.
During the introduction of N5P to investors, TSMC stated that the second generation process node would allow manufacturers to achieve either 15% better energy efficiency or 7% higher performance.
For this reason, Apple typically opts for efficiency rather than performance gains within different generations of the same processor nodes. Therefore, we can expect a very modest increase in performance values for Apple A15 compared to A14 and a more significant reduction in power consumption of 10 to 15%.
It’s a constant compromise that phone makers have gotten very used to as they can choose between raw power or power consumption optimization with each subsequent generation of mobile phones and meet somewhere in the middle as phones are already fast enough for whatever you throw at them .
The report also says TSMC is ready to launch a new 4nm node that will begin risk production at the end of this year and will reach mass volume in 2022. However, rumor has it that this is more likely to apply to the Apple M2 laptop than the Apple M2 laptop, but Apple still has plenty of time to decide.
