Intel Xeon Gold 6312U — 24 cores and 48 threads at 2.4 GHz base / 3.6 GHz turbo, 36 MB cache, 185 W TDP, FCLGA4189. Supplied from stock with a 1-year warranty.
The 6312U belongs to the 3rd Gen Xeon Scalable (Ice Lake-SP) family, launched in Q2 2021 on a 10 nm process. It pairs 24 cores / 48 threads with a 2.4 GHz base and a 3.6 GHz turbo ceiling on a 185 W envelope, plus PCIe 4.0 with 64 lanes. The chip is rated 1S Only (single socket) - it is built for single-socket nodes and carries no second-CPU pairing - and it runs DDR4-3200 across eight channels with a 6 TB per-socket ceiling; Intel Optane persistent memory 200 series is supported alongside DDR4. Speed Select comes as Core Power, Turbo Frequency and Base Frequency variants, with a high-priority / low-priority partition of 8 cores at 2.6 GHz and 16 cores at 2.3 GHz underneath. Thermal rating is TCASE 80 °C in a 77.5 mm × 56.5 mm package, and Embedded Options are Available for long-life appliance builds.
Security and acceleration are Ice Lake staples: AVX-512 with two FMA units, DL Boost, TSX-NI and VMD, Intel Crypto Acceleration, Resource Director Technology and Speed Shift, plus Total Memory Encryption, Run Sure reliability and Platform Firmware Resilience. SGX is supported with Intel SPS and a 64 GB enclave page cache.

The 6312U fits single-socket configurations of FCLGA4189 (Whitley) platforms whose BIOS supports 3rd Gen Xeon Scalable parts. With 24 cores inside a 185 W envelope and the full DDR4-3200 memory ceiling in a single-socket design, it targets scale-out density - roles that value core count per node over clock spread:
Because the part is 1S Only, populate it as the only processor in the node - confirm the platform BIOS supports single-socket Ice Lake parts before ordering, and confirm the chassis cooling is rated for a 185 W processor. The 48-thread node total with the 16-core low-priority partition suits throughput-oriented roles: storage front ends, hyper-converged infrastructure and warm-tier databases.

The spec table rows for the 6312U and the Gold 6336Y are identical figure for figure - 24 cores, 2.4 GHz base, 3.6 GHz turbo, 36 MB of cache, 185 W - but the parts are not interchangeable: the 6312U is rated 1S Only, its high-priority partition runs 100 MHz faster (8 cores at 2.6 vs 2.5 GHz) and its low-priority partition 100 MHz faster (16 cores at 2.3 vs 2.2 GHz), and it omits the 6336Y Performance Profile tier table. Against the 32-core Gold 6338 it gives up 8 cores and 12 MB of cache while running 400 MHz higher at base (2.4 vs 2.0 GHz) and 400 MHz higher at turbo (3.6 vs 3.2 GHz) on 20 W less. Against the Gold 6338T it runs 300 MHz higher at base and 200 MHz higher at turbo on 20 W more (185 vs 165 W). Against the 32-core Gold 6314U it trades 8 cores and 12 MB of cache for 100 MHz more base and 200 MHz more turbo on 20 W less, both parts being 1S Only.
Every 6312U carries a 1-year warranty covering defects in workmanship and function; a verified faulty unit is replaced or refunded with return shipping covered. New units come in Intel tray packaging (order code CD8068904658902); tested pull units are labelled as such and priced separately. In-stock units typically ship within 2-3 business days after payment confirmation.
