Using the faster SSD in the high-end MacBook Pro, the system can also swap data on the memory with the SSD if it needs to do so. This means that high memory usage does not necessarily indicate that you need additional memory. MacOS intelligently optimizes memory usage in the background, filling up much of the available RAM for better performance. Overall, this means that the new MacBook Pro's memory performance is massively improved compared to previous MacBook Pro models, as well as most PCs.ĭecisions about getting either 16GB or 32GB of memory should therefore be rooted in the understanding that the MacBook Pro's memory is not conventional RAM, but rather a much faster unified memory architecture. The MacBook Pro's substantially different memory hardware is the basis for its improved memory performance, but the ‌M1 Pro‌ MacBook Pro is also bolstered by 200GB/s unified memory and a faster, 7.4GB/s SSD, which means that the memory is much quicker and the system can swap with the SSD faster. This allows all of the technologies in the SoC to access the same data without copying it between multiple pools of memory, which significantly improves performance and efficiency. This brings together high-bandwidth, low-latency memory into a single pool within a custom package.

Like the M1 and M2 chips, the ‌M1 Pro‌ features a unified memory architecture. With Apple silicon chips, these technologies are combined into a single System on Chip (SoC), delivering a new level of integration for improved performance and power efficiency. Macs and PCs have traditionally needed to use multiple chips for the CPU, RAM, I/O, and more.

When choosing your ‌M1 Pro‌ MacBook Pro configuration, should you upgrade to the 32GB memory option, and does it justify its cost? Our guide helps to answer the question of how to decide which of these two memory options for the high-end MacBook Pro is best for you. Apple's high-end 14-inch and 16-inch MacBook Pro offers the M1 Pro chip with 16GB of RAM as standard, but you can upgrade to 32GB of RAM for $400.
