Intel Xeon Platinum 8358P Processor

Intel Xeon Platinum 8358P — 32 cores and 64 threads at 2.6 GHz base / 3.4 GHz turbo, 48 MB cache, 240 W TDP, FCLGA4189. Supplied from stock with a 1-year warranty.

The power-optimised 32-core of the Ice Lake Platinum stack

The 8358P belongs to the 3rd Gen Xeon Scalable (Ice Lake-SP) family, launched in Q2 2021 on a 10 nm process. It pairs 32 cores / 64 threads with a 2.6 GHz base and a 3.4 GHz turbo ceiling on a 240 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 DDR4-3200 across eight channels with a 6 TB per-socket ceiling - Intel Optane persistent memory 200 series is supported alongside DDR4. Intel Speed Select comes as Core Power and Turbo Frequency variants.

Security and acceleration are Ice Lake Platinum 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 an 8 GB enclave page cache. Thermal rating is TCASE 80 °C in a 77.5 mm × 56.5 mm package.

Technical specifications

Servers that commonly take this processor

The 8358P fits any FCLGA4189 (Whitley) platform whose BIOS supports 3rd Gen Xeon Scalable parts, in single- or dual-CPU two-socket systems. Typical systems that run it include:

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

Because the part is rated 2S with three UPI links, it can pair with a second 8358P in dual-socket nodes - check that the platform BIOS and the second CPU stepping are compatible before ordering, and make sure the chassis cooling is rated for two 240 W processors.

How it compares across generations

Against its closest sibling, the Platinum 8358, the 8358P gives up nothing on compute - core, thread, clock and cache counts are identical - but runs a 10 W tighter 240 W envelope with an 80 °C TCASE and a far smaller 8 GB SGX enclave ceiling (the 8358 allows 64 GB), and ships without the 8358’s published Base Frequency Speed Select profile or its high/low-priority core partition. Next to its Gold sibling, the 32-core 6338, it runs the base clock 600 MHz higher and the turbo 200 MHz higher on the same core, thread and cache counts, for a 35 W larger envelope. Stepping up to the higher-clocked Platinum 8362 adds 200 MHz on both clocks (2.8/3.6 vs 2.6/3.4 GHz) for 25 W more.

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 (SRKJ0) 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 8358P 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 CD8068904599101); tested pull units are labelled as such and priced separately. In-stock units typically ship within 2-3 business days after payment confirmation.
