In a note to investors obtained by AppleInsider on Monday, KGI analyst Ming-Chi Kuo says he expects Apple's 2017 laptop line to focus on internal component updates, notably platform-wide adoption of Intel's Kaby Lake architecture. Of interest to professionals, Apple is predicted to start manufacture of a 15-inch MacBook Pro with up to 32GB of RAM in the fourth quarter, double the memory allotment of current top-of-the-line models. Kuo speculates the company will be forced to adopt desktop RAM due to restrictions of current memory system designs. Apple took flak in releasing its latest MacBook Pro with Touch Bar models with a hard memory cap of 16GB, an minimal allotment viewed as a negative for imaging and video professionals. Responding to customer criticism, Apple said the move was made in a bid to maximize battery life. On more than one occasion, SVP of Worldwide Marketing Phil Schiller defended the decision to limit RAM allotments to 16GB, saying higher amounts would require a power-hungry memory controller unsuitable for use in portable machines.

Essentially, the Intel Skylake CPUs used in Apple's MacBook Pro only support up to 16GB of LPDDR3 RAM at 2133MHz. Though Intel does make processors capable of addressing more than 16GB of memory, those particular chipsets rely on less efficient DDR4 RAM and are usually deployed in desktops with access to dedicated mains power. In order to achieve high memory allotments and keep unplugged battery life performance on par with existing MacBook Pro models, Apple will need to move to an emerging memory technology like LPDDR4 or DDR4L. Such hardware is on track for release later this year. Beyond the high-end 15-inch model, Kuo expects Apple to start production of new 13- and 15-inch MacBook Pros in the third quarter of 2017.
