Apple may separate RAM from the processor for more AI power in future iPhones

Apple is reportedly joining forces with Samsung to change the approach to RAM (Random Access Memory) packaging in future iPhone models. The main goal is to increase bandwidth to better handle artificial intelligence (AI) tasks.

Apple is reportedly teaming up with Samsung to change the way RAM is packaged in future iPhone models.

Why is this important?”

.

Modern smartphones typically have RAM integrated on the same chip as the processor. However, Apple plans to separate the RAM and processor on different chips, which should:

• Accelerate memory access for AI tasks.
• Reduce device heating when performing intensive computations.

Samsung’s Role

According to The Elec, Apple has commissioned Samsung to explore the possibility of creating larger DRAM packages that would provide:

• Enhanced speed of memory performance.
• Improved heat dissipation, which is especially relevant for AI tasks.

Samsung is just beginning research, while Apple plans to introduce the technology in its iPhone 18 lineup in 2026.

Why not HBM?

.

Apple could have used high-bandwidth memory (HBM) popular in servers. However, the idea was abandoned because of:

High-speed memory.

• The large size of HBM, which prevents it from being used in compact smartphones.
• High power consumption, which is inappropriate for mobile devices.

Challenges and trade-offs

To accommodate separate RAM and processor chips, Apple may face challenges:

• Reducing space inside the device, which may require downsizing the processor or even the battery.
• Optimizing power consumption so as not to sacrifice battery life.

Predictions

If Apple successfully implements this approach, it could be a breakthrough for smartphone performance, especially in AI. However, the company must decide how to minimize trade-offs, such as reduced battery capacity.

And if it does, the company will have to figure out how to minimize the trade-offs, such as reduced battery capacity.

Separating RAM and CPU could significantly boost the iPhone’s AI capabilities, but it’s critical that it doesn’t affect the device’s longevity. Apple is known for its attention to detail, so hopefully they’ll find an optimal solution.
