Intel Xeon Gold 5318Y — 24 cores and 48 threads at 2.1 GHz base / 3.4 GHz turbo, 36 MB cache, 165 W TDP, FCLGA4189. Supplied from stock with a 1-year warranty.
The 5318Y 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 2.1 GHz base and a 3.4 GHz turbo ceiling on a 165 W envelope, plus PCIe 4.0 with 64 lanes. The chip scales across two sockets over three UPI links at 11.2 GT/s and runs DDR4-2933 across eight channels with a 6 TB per-socket ceiling; Intel Optane persistent memory 200 series is supported alongside DDR4. Speed Select comes as a three-profile SST-PP table - 24 cores at 2.1 GHz / 165 W, 24 cores at 1.9 GHz / 150 W and 22 cores at 2.0 GHz / 150 W - on top of Core Power, Turbo Frequency and Base Frequency variants, with a high-priority / low-priority partition of 8 cores at 2.3 GHz and 16 cores at 1.8 GHz underneath. Thermal rating is TCASE 87 °C in a 77.5 mm × 56.5 mm package, and it is an Embedded Options Available part, suiting it to long-life appliance and edge designs as well as standard servers.
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 5318Y fits FCLGA4189 (Whitley) platforms whose BIOS supports 3rd Gen Xeon Scalable parts, in single- or dual-socket layouts. With 24 cores inside a 165 W envelope at the DDR4-2933 memory tier, it targets capacity-first mainstream nodes - roles that need core count and profile flexibility without the thermal bill of the 185-205 W parts:
In dual-socket builds the three UPI links keep cache-coherent traffic at full bandwidth, giving a 48-core / 96-thread node total. Confirm the platform BIOS supports Ice Lake parts before ordering, and confirm the chassis cooling is rated for a 165 W processor. The 16-core low-priority partition at 1.8 GHz suits throughput-oriented roles: storage front ends, hyper-converged infrastructure and warm-tier databases.
| Processor | Generation | Cores / Threads | Base / Max turbo | Cache | TDP | Memory support |
|---|---|---|---|---|---|---|
| Xeon Platinum 8280 | 2nd Gen (Cascade Lake) | 28 / 56 | 2.7 / 4.0 GHz | 38.5 MB | 205 W | 6ch DDR4-2933 |
| Xeon Gold 6338T | 3rd Gen (Ice Lake-SP) | 24 / 48 | 2.1 / 3.4 GHz | 36 MB | 165 W | 8ch DDR4-3200 |
| Xeon Gold 5320 | 3rd Gen (Ice Lake-SP) | 26 / 52 | 2.2 / 3.4 GHz | 39 MB | 185 W | 8ch DDR4-2933 |
| Xeon Gold 5318Y | 3rd Gen (Ice Lake-SP) | 24 / 48 | 2.1 / 3.4 GHz | 36 MB | 165 W | 8ch DDR4-2933 |
It matches the 24-core Gold 6338T core for core - the same 2.1 GHz base, 3.4 GHz turbo, 36 MB of cache and 165 W envelope - but runs memory one tier down at 2933, adds a three-profile SST-PP table and drops the low-priority partition 100 MHz to 1.8 GHz. Against the 26-core Gold 5320 it gives up 2 cores and 3 MB of cache and runs 100 MHz lower at base (2.1 vs 2.2 GHz) on 20 W less, keeping the same 3.4 GHz turbo and DDR4-2933 memory tier. Next to the 2nd Gen Platinum 8280 it offers 4 fewer cores with 2.5 MB less cache, a 600 MHz lower base and a 600 MHz lower turbo on 40 W less, and adds PCIe 4.0 with 64 lanes and eight memory channels over the older part’s 48 lanes and six.
Every 5318Y 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 CD8068904656703); tested pull units are labelled as such and priced separately. In-stock units typically ship within 2-3 business days after payment confirmation.
