M4 iPad Pro CPU cores and RAM amount are tied to storage capacity

Yesterday, when Apple announced the Apple M4 chip at its iPad Pro event, it mentioned that the chip comes with “up to” four high-performance processor cores.

These short and easily forgettable words always mean that there will be a low-end version of the chip coming. doesn’t include that many processor cores, and the new iPad Pro’s tech specs page has all the details: iPad Pros with 256GB or 512GB of storage use a version of the M4 with three high-performance processor cores and six processor cores. smaller efficiency. Only models with 1TB and 2TB of storage feature an M4 with all four high-performance CPU cores enabled.

The 256GB and 512GB models also come with 8GB of RAM, while the 1TB and 2TB models come with 16GB of installed memory. Although these changes are clearly stated on the technical specifications page, the actual configuration page for the iPad Pro in Apple’s online store gives no indication that the storage upgrade also upgrades your CPU and RAM.

All iPad Pro M4s come with a fully enabled 10-core GPU, 16-core Neural Engine, and 120 GB/s of memory bandwidth. And all iPad Air M2 models come with the same fully enabled M2 chip and 8GB of RAM.

This is different from how Apple handles upgrades for Macs, which typically allow flexible build-to-order configurations where you can upgrade individual specs without having to upgrade everything at once.

This phenomenon is not new, at least not for RAM. The Apple A12X-powered iPad Pro 2018, the first to adopt a modern thin-bezel design, included 4GB of RAM in the base models and 6GB of RAM in the 1TB model. The iPad Pro M1 and M2 each come with 8GB of RAM in their low-end configurations and 16GB in the 1TB and 2TB configurations. This is, however, the first time Apple has tied iPad processor performance to storage capacity , meaning the base iPad Pros won’t offer as big an upgrade over the M2 models as the more expensive versions.

As for why Apple does this for its processors, that’s not the case. just a way to sell potential buyers on high-end iPads. Silicon chips often have small defects, especially when they are made using completely new manufacturing processes, like the second-generation 3nm process used for the M4. Selling a partially disabled version of the chip allows Apple (and other chipmakers) to use imperfect silicon chips instead of throwing them away, a process known as “binning.”

The 1TB and 2TB iPad Pros are also the only ones that can be upgraded with Apple’s “nano-textured glass,” which gives your screen a matte finish rather than glossy and glassy. Upgrading the nano-texture costs $100 on top of the $600 you’ll spend to upgrade storage and other components.
