Intel Xeon Gold 6330N Processor

Intel Xeon Gold 6330N — 28 cores and 56 threads at 2.2 GHz base / 3.4 GHz turbo, 42 MB cache, 165 W TDP, FCLGA4189. Supplied from stock with a 1-year warranty.

The network-tuned 28-core Gold of the Ice Lake stack

The 6330N belongs to the 3rd Gen Xeon Scalable (Ice Lake-SP) family, launched in Q2 2021 on a 10 nm process. It pairs 28 cores / 56 threads with a 2.2 GHz base and a 3.4 GHz turbo ceiling on a 165 W envelope, plus PCIe 4.0 with 64 lanes. The chip is rated 2S (two sockets) with three UPI links at 11.2 GT/s, and it runs DDR4-2667 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 18 cores at 2.3 GHz and 10 cores at 1.9 GHz underneath. Thermal rating is TCASE 86 °C - one degree under the 87 °C ceiling of the Gold 6338T - 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.

Technical specifications

Servers that commonly take this processor

The 6330N fits any FCLGA4189 (Whitley) platform whose BIOS supports 3rd Gen Xeon Scalable parts, in single- or dual-CPU two-socket systems. The N suffix marks the network and communication bin: 28 cores inside a 165 W envelope leaves generous power headroom for loaded NICs, accelerators and NVMe backends:

• Dell PowerEdge R750 / R650
• HPE ProLiant DL380 Gen10 Plus / DL360 Gen10 Plus
• Lenovo ThinkSystem SR650 V2 / SR630 V2
• Two-socket appliance, edge and storage chassis built around the Whitley platform

Because the part is rated 2S with three UPI links, it can pair with a second 6330N in dual-socket nodes - check that the platform BIOS and the second CPU stepping are compatible before ordering, and confirm the chassis cooling is rated for two 165 W processors. The 56-thread node total with the wide 18-core high-priority partition suits SDN control planes, 5G user-plane functions, storage front ends and virtualisation hosts that mix latency-sensitive and background threads.

How it compares across generations

Against the 32-core Gold 6338N, the 6330N gives up 4 cores and 6 MB of cache for a 100 MHz lower turbo (3.4 vs 3.5 GHz) and 20 W less (165 vs 185 W) on the same DDR4-2667 memory. Against the Gold 6330 it keeps the identical 28-core / 56-thread / 42 MB layout but runs 200 MHz higher at base, 300 MHz higher at turbo and 40 W less, trading the memory ceiling down one step to DDR4-2667. Against the thermally flexible 6338T it carries 4 more cores and 6 MB more cache at the same 165 W, giving up the DDR4-3200 ceiling. Against the Cascade Lake flagship Platinum 8280 it holds the same 28-core / 56-thread shape while adding PCIe 4.0, eight memory channels and a 6 TB ceiling at 40 W less.

How each processor is tested before it ships

1. Visual inspection of the heat spreader, capacitors and substrate on arrival.
2. Thermal paste residue cleaned from the IHS; socket contact pads checked under magnification.
3. sSpec marking (SRKH9) verified against the order line before testing.
4. Full-core load test on an LGA4189 diagnostic board, confirming rated clocks and cache.
5. Re-run of the memory controller stress pass, then anti-static packing for dispatch.

Warranty and lead time

Every 6330N 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 CD8068904582501); tested pull units are labelled as such and priced separately. In-stock units typically ship within 2-3 business days after payment confirmation.
