Intel Crescent Island leak reveals 160 GB LPDDR5X PCIe accelerator

A leaked PCB from YuuKi_AnS gives the first real look at Intel's Crescent Island PCIe accelerator. The Xe3P GPU die dwarfs the Xe2-based BMG-G31 in current Arc cards. This architecture targets everything from client integrated graphics to data center inference workloads, positioning Intel for a broader market than its current consumer gaming push.

Memory is the standout spec. Twenty LPDDR5X sites deliver 160 GB total — 12 on the front, 8 on the back — confirming April rumors from leaker Jaykihn. Intel chose LPDDR5X over HBM to dodge supply constraints and trim costs, accepting lower bandwidth in exchange. The board also shows 13 populated VRM stages and a single 16-pin power connector.

No gaming variant appears planned. Intel recently launched the Arc Pro B70 and B65 professional cards on Battlemage Xe2 silicon, while chatter around a high-end Arc B770 gaming model has gone quiet ahead of Computex. The leaked PCB reportedly matches a near-final design, suggesting Crescent Island will focus on professional and data center deployments rather than consumer gaming.
