Intel's Crescent Island AI chip focuses on inference efficiency with Xe3P architecture

Intel presented its Crescent Island AI accelerator at Hot Chips, a 350W air-cooled PCIe card with up to 480GB of LPDDR5X memory for inference tasks. The chip uses the Xe3P architecture, featuring 32 Xe cores with a total of 256 XMX matrix accelerators. Intel designed it to maximize AI FLOPS per watt, targeting a lower-power niche compared to rival GPUs.
