It is a 32 Xe core part with five Xe3p cores per Compute Slice across four slices. Intel gives a 350W TDP, keeps air cooling, and adds native MxFP4 support using the OCP block size 32 definition without custom extensions. Shipments were discussed for the second half of 2026.","whyItMatters":"Intel is positioning Crescent Island as an AI-first server GPU built around power efficiency and KV cache capacity rather than peak throughput, a bet that its Arc Pro B-series lineage can be redirected at agent workloads while SambaNova's SN50 fills the Xeon pairing role.","webCardHtml":"\u003cp\u003eCrescent Island keeps the consumer Xe lineage rather than the Xe-HPC line: eight Vector and eight XMX units make up one Xe core, grouped five cores to a Compute Slice, four slices to the part. The Xe3p additions are FP4 support and a 16x16 systolic array inside XMX, which Intel did not extend beyond OCP\u0026#39;s block size 32 MxFP4 format. Intel set a 350W TDP and stressed that air cooling remains the target, framing the design around performance per watt instead of absolute throughput.\u003c/p\u003e","blueskyPost":"Intel's Crescent Island: 32 Xe3p cores, 350W TDP, air cooled, native MxFP4 at OCP block size 32.
