Intel Crescent Island GPU officially supports up to 480GB LPDDR5X memory

Intel confirms 160GB Crescent Island design, partners may go up to 480GB

Intel has shared more details on Crescent Island at Computex 2026. The GPU is based on the Xe3P architecture and is aimed at AI inference workloads rather than gaming.

Intel previously confirmed Crescent Island with 160GB of LPDDR5X memory. According to the latest report from Computex, this is the reference configuration. Board partners may be able to build cards with up to 480GB of LPDDR5X memory.

This would make Crescent Island unusual among data-center GPUs. Intel is not using HBM or GDDR memory for this design. The company is instead relying on LPDDR5X, which offers higher capacity per board and lower power use, but lower bandwidth than HBM-based accelerators.

350W Data Center GPU

Crescent Island has a 350W power target. That would place it in air-cooled server territory. Intel already said the product is designed for enterprise servers and inference deployments, with customer sampling planned for the second half of 2026.

We previously covered Crescent Island PCB leaks showing room for 20 LPDDR5X packages. Those leaks already pointed to 160GB on the reference board and mentioned higher-capacity configurations as a possibility. A 480GB model would likely depend on higher-density LPDDR5X packages and partner board designs.

Intel has not shared compute performance figures yet. The company only confirmed broad data type support, including lower-precision formats for AI inference and FP64 support for compute workloads. For now, the memory capacity is the main spec Intel is ready to talk about.
