At Hot Chips 2026, Intel detailed Crescent Island, a data center and workstation GPU built on the new Xe3P architecture for AI inference. It packs 32 Xe3P cores and up to 480GB of LPDDR5X memory in a 350W, air-cooled PCIe card, with customer sampling targeted for the second half of 2026.
Intel used Hot Chips 2026 to lay out full details on Crescent Island, its next data center and workstation GPU aimed squarely at AI inference rather than graphics rendering. According to TechPowerUp and Wccftech, the card is built on the new Xe3P architecture and ships as a 350W, air-cooled PCIe card. Intel's own reference design carries 160 GB of LPDDR5X memory, but the company is allowing ODM partners to build variants with up to 480 GB, giving builders significant flexibility in memory capacity depending on workload needs.
Under the hood, Crescent Island uses four Compute Slices totaling 32 Xe3P cores, 256 Vector Engines, and 256 XMX engines, backed by 32 MB of unified L2 cache and 512 KB of L1/SLM cache per core. Wccftech notes the XMX engines have been redesigned with a 16-deep systolic array (up from four-deep on regular Xe3), and the chip supports data types from FP4 up to FP64. Notably, Crescent Island has no traditional graphics output blocks — the silicon is purpose-built for GPGPU inference workloads, freeing up die area for additional AI compute.
Intel is positioning LPDDR5X memory as a cost and power advantage over the HBM3E/HBM4 memory used in competing data center accelerators. Wccftech's comparison lists Crescent Island at up to 480 GB (LPDDR5X) versus AMD's Instinct MI450X at up to 432 GB (HBM4) and NVIDIA's Vera Rubin at up to 288 GB (HBM4), with LPDDR5X offering lower power draw and easier sourcing amid tight HBM supply. Intel is targeting customer sampling for Crescent Island in the second half of 2026, with day-zero support planned for major AI frameworks including vLLM, SGLang, llm-d, and NVIDIA Dynamo.
