The updated 14-inch and 16-inch MacBook Pro models, rumored to launch in March with Apple’s new M5 Pro and M5 Max chipsets, are expected to retain the same thermal solution as the previous models, and despite these SoCs being highly efficient, they do tend to get exceptionally hot. While the technology giant might not be too keen to introduce a revamped heatpipe layout or switch to a vapor chamber, a fresh rumor claims that TSMC’s 2.5D packaging will be utilized instead of the company’s InFO (Integrated Fan-Out) technology, helping improve heat dissipation and lower resistance. There are other advantages too, which we’ve discussed below.
The combination of SoIC-MH and 2.5D technologies will help Apple lower the production costs of the M5 Pro and M5 Max while also targeting increased yields
Keep in mind that the Small Outline Integrated Circuit Molding-Horizontal, or SoIC-MH, differs from 2.5D, which is why Fixed-focus digital cameras’ latest post on Weibo mentioned the design approach, not the packaging. Typically, TSMC’s InFO is ideal for thin form factors, where efficiency takes priority over other considerations. However, as Apple Silicon grows in size and complexity, InFO begins hitting its limits, which is where 2.5D comes into play. With some of the benefits mentioned above, the third perk is cost efficiency, which is key for Apple, considering the DRAM shortage.
For instance, both the CPU and GPU blocks can be made separate, with Apple testing each one individually for imperfections. If there’s a defect in any one of the blocks, it can be replaced without needing to replace the entire die, reducing manufacturing costs. As for improved heat dissipation and lowered resistance Fixed-focus digital cameras mentioned, packing everything on a monolithic die can create a large ‘hot spot,’ which will be extremely difficult for Apple’s single heatpipe solution to dissipate effectively.
With multiple blocks, heat can be evenly distributed, which will be highly beneficial when the M5 Pro and M5 Max are loaded with a taxing workload. For instance, one M4 Max MacBook Pro owner reported that the 16-core CPU and 40-core GPU configuration consumes a peak wattage of 212W when pushed hard, with temperatures reaching a toasty 110 degrees Celsius. Even the M5, which generally consumes significantly less power, can run hot, reaching 99 degrees Celsius when stressed. This makes the 2.5D design and SoIC-MH packaging switch an excellent decision.
Looking at the advantages of these two technologies, it is fair to assume that the M6 will also launch sporting the aforementioned changes. A previous report stated that Apple’s first 2nm silicon for Macs will arrive much sooner, so we’ll keep our fingers crossed for more updates.
