Apple 14-Inch MacBook Professional M2 Teardown Reveals Massive Adjustments Because of Substrate Pricing

Posted on

Apple’s bean counters certainly kind some of the highly effective forces inside the group, regardless of a lot of the corporate’s high-profile success being tied to design. A living proof is supplied by certainly one of Apple’s main new shopper merchandise, the 2023 14-inch MacBook Professional, which has had its design considerably steered by pricing fluctuations within the supplies and elements markets. 

iFixIt not too long ago tore down one of many laptops, and was stunned on the change in SoC measurement, cooler measurement, and NAND efficiency. Chief Analyst at SemiAnalysis, Dylan Patel, was conscripted to shine a lightweight on these adjustments and supply a proof.

Why Is the Heatsink Smaller?

Opening up the brand new 2023 14-inch MacBook Professional M2 for the primary time, the iFixIt staff had anticipated the cooling answer to be beefed-up and bolstered in comparison with the earlier M1 Professional model. In spite of everything, the M2 Professional inside this laptop computer was trumpeted as packing 40 billion transistors (opens in new tab) — practically 20 % greater than M1 Professional, and double the quantity in M2. It was additionally claimed to supply 200GB/s of unified reminiscence bandwidth — twice that of M2. Extra usefully, in comparison with the direct previous-gen predecessor, the M2 Professional was claimed by Apple to have a CPU that is about 20% sooner and a GPU as much as 30% sooner.

So, the heatsink / cooling meeting being instantly noticeably smaller was fairly a shock for the tech disassembly specialists. Then, when iFixIt deshielded the M2 Professional, they instantly noticed the brand new SoC was a lot smaller, with the principle cause being the brand new onboard RAM configuration.

Within the image above, you’ll be able to see the brand new SoC to the precise. Patel defined that Apple instigated this alteration when the ABF substrates had been in very quick provide, so optimizing to this design constraint was extremely pragmatic. The way in which Apple selected to do that is by altering from the dual-8GB LPDDR5 RAM configuration to quad-4GB LPDDR5 RAM chips.
