The introduction of a vapor chamber enabled the iPhone 17 Pro and iPhone 17 Pro Max to deliver better sustained performance, but Apple is expected to bring changes at a deeper level next year when it announces the iPhone 18 family. The A20 and A20 Pro will definitely benefit from TSMC’s 2nm ‘N2’ process, but a chipset’s packaging also makes a monumental difference. According to the latest rumor, this change will improve heat dissipation, resulting in increased performance.
The switch from InFO (Integrated Fan-Out) to WMCM (Wafer-level Multi-Chi Module) will make all the difference in the world for the iPhone 18 series - Here is why
On Weibo, the tipster Fixed Focus Digital, who now goes by the machine-translated name ‘Fixed-focus digital cameras,’ has provided details on the iPhone 17 series’ dominating run in China. Next, he turns his attention to the iPhone 18 lineup that is slated to arrive in the third quarter of next year. Out of the several technological advancements that Apple is reported to bring to the A20 and A20 Pro next year, perhaps the most significant one will be transitioning from InFO (Integrated Fan-Out) to WMCM (Wafer-level Multi-Chi Module) packaging.
For those unfamiliar, WMCM will enable better efficiency for the A20 and A20 Pro, thanks to the tighter integration of various dies. Each die will house the CPU, GPU, NPU, and other components that will act autonomously, rather than being packaged on a single die. This approach helps reduce power consumption as all of these parts will act independently as part of the new design. In short, TSMC’s 2nm process will help, but any improvements are always welcome.
Of course, Apple will likely retain the vapor chamber on the iPhone 18 Pro and iPhone 18 Pro Max, but here’s something you probably didn’t anticipate: this passive cooling solution is expected to make its way to the iPhone Fold, which will reportedly be announced alongside the Cupertino firm’s flagship offerings. The additional cooling should allow the A20 and A20 Pro to obtain better sustained performance than the A19 and A19 Pro.
To give you an idea of how the A19 Pro fares, we recently compared its performance in Where Winds Meet. To our surprise, the chipset produces a better experience than the Snapdragon 8 Elite Gen 5, which was not only cooled with REDMAGIC 11 Pro’s liquid cooling solution but also a dedicated fan. These results should provide you with a brief overview of what to expect from the iPhone 18 series, but for the time being, treat this rumor with a pinch of salt, and we will return with more updates.
