Intel has unveiled its D-series Crescent Island inference graphics cards, powered by the Xe3P microarchitecture. The flagship D270 model features 32 Xe3P cores and 256 XMX engines. Unlike standard Xe3 designs, the XMX engines in this chip utilize a 16-deep processing structure.
The hardware is optimized specifically for AI inference tasks, such as long-context processing and agentic workloads, rather than model training. The D270 supports up to 480 GB of LPDDR5X memory. Each core includes 1 MB of register file space and 512 KB of L1 cache, complemented by 32 MB of unified L2 cache.
The architecture supports FP4 and FP8 data formats. To handle multimodal tasks involving video, the chip integrates a media engine equipped with four encoders and four decoders. Notably, the silicon lacks traditional graphics processing elements, as it is designed exclusively for inference operations.
