Apple A20 Pro May Skip LPDDR6 RAM, But New Memory Changes Could Help AI Performance

Apple’s upcoming A20 Pro chip may not support LPDDR6 RAM, but fresh details suggest the company has another plan to improve memory bandwidth for heavier on-device AI tasks on the iPhone 18 Pro models.

According to the shared schematics, Apple will use six-channel LPDDR5X memory with a 96-bit bus width on the A20 Pro. This marks a clear change from the older 4-channel memory setup with a 64-bit bus width, which limited how much data the chip could move at once.

On-device AI models need fast access to memory because these tasks depend heavily on data movement, not just raw processing power. A wider bus gives the chip more room to move that data, so the Neural Engine can handle larger AI workloads without waiting too long for information to arrive.

Why Apple Is Changing The Memory Design

The A20 Pro is also expected to move away from Apple’s older inFO-PoP packaging and use Wafer-Level Multi-Chip Module Packaging, also known as WMCM. This change helps Apple separate the DRAM from the main chip die, which can improve heat control during demanding tasks.

Better heat management also matters because AI workloads can run for longer periods, and the chip needs to maintain stable performance instead of slowing down quickly under pressure.

No LPDDR6, But Still A Big Upgrade

LPDDR6 support would have offered another jump in memory speed, but Apple appears to be focusing on bandwidth through a wider bus and improved packaging. If these details prove accurate, the A20 Pro will still bring a meaningful upgrade for Apple Intelligence and other on-device AI features.

The iPhone 18 Pro and iPhone 18 Pro Max are expected to benefit most from this change, especially as Apple pushes more AI processing directly on the device.
