Frequently Asked Questions
Intel Xeon Gold 6430 — 32 cores and 64 threads at 2.1 GHz base / 3.4 GHz turbo, 60 MB cache, 270 W TDP, FCLGA4677. Supplied from stock with a 1-year warranty.
A 32-core mainstream Gold with dual-socket scalability
The 6430 belongs to the 4th Gen Xeon Scalable (Sapphire Rapids) family, launched in Q1 2023 on the Intel 7 process. It pairs 32 Performance-cores at 2.1 GHz all-core with a 3.4 GHz turbo ceiling, 60 MB of cache and a 270 W envelope. As a mainstream Gold SKU it is rated 2S — validated for platforms with up to two sockets — which covers single- and dual-socket servers alike. Speed Select Technology adds three levers: Core Power splits the die into 12 high-priority cores at 2.2 GHz and 20 low-priority cores at 1.8 GHz, Turbo Frequency can lift the turbo ceiling on chosen cores, and Base Frequency raises the all-core floor. It ships without SST-PP, so there are no folded core-count profiles to configure.
The platform: 8 channels of DDR5-4400 (at both 1 DPC and 2 DPC, up to 4 TB per socket), PCIe 5.0 with 80 lanes, and 3 UPI links at 16 GT/s to feed multi-socket topologies. Its accelerator quota ships pre-activated — one DSA device by default, plus AMX and DL Boost, with Intel QAT available as software acceleration and further accelerator devices unlockable through Intel On Demand.

Servers that commonly take this processor
The 6430 uses the FCLGA4677 (Socket E) package and is validated for 2-socket 4th Gen Xeon Scalable platforms. Typical systems that run it include:
- Dell PowerEdge R660 / R760 / R6625 / R7625
- HPE ProLiant DL380 Gen11 / DL360 Gen11 / DL384 Gen11
- Lenovo ThinkSystem SR650 V3 / SR630 V3 / ST650 V3
- Inspur NF5280M6-class and other LGA4677 rack platforms
Most 5th Gen (Emerald Rapids) boards also accept it. Check that the chassis thermal design is rated for the 270 W TDP and that the BIOS is current, especially if the server originally shipped with a lower-power SKU.
How it compares across generations
| Processor | Generation | Cores / Threads | Base / Max turbo | Cache | TDP | Memory support |
|---|---|---|---|---|---|---|
| Xeon Platinum 8160 | 1st Gen (Skylake-SP) | 24 / 48 | 2.1 / 3.7 GHz | 33 MB | 150 W | 6ch DDR4-2666 |
| Xeon Platinum 8260 | 2nd Gen (Cascade Lake) | 24 / 48 | 2.4 / 3.9 GHz | 35.75 MB | 165 W | 6ch DDR4-2933 |
| Xeon Platinum 8360Y | 3rd Gen (Ice Lake) | 36 / 72 | 2.4 / 3.5 GHz | 54 MB | 250 W | 8ch DDR4-3200 |
| Xeon Gold 6430 | 4th Gen (Sapphire Rapids) | 32 / 64 | 2.1 / 3.4 GHz | 60 MB | 270 W | 8ch DDR5-4400 |
| Xeon Platinum 8562Y+ | 5th Gen (Emerald Rapids) | 32 / 64 | 2.8 / 4.0 GHz | 96 MB | 300 W | 8ch DDR5-5600 |
Moving from Ice Lake to Sapphire Rapids roughly doubles the cache across the Gold range and switches the platform to DDR5 and PCIe 5.0; the 6430 adds AMX for inference workloads and an on-die DSA accelerator its predecessors could not offer, plus Speed Select core-priority controls.
How each processor is tested before it ships
- Visual inspection of the heat spreader, capacitors and substrate on arrival.
- Thermal paste residue cleaned from the IHS; socket contact pads checked under magnification.
- sSpec marking (SRM7A) verified against the order line before testing.
- Full-core load test on an LGA4677 diagnostic board, confirming rated clocks and cache.
- Re-run of the memory controller stress pass, then anti-static packing for dispatch.
Warranty and lead time
Every 6430 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 PK8071305072902); tested pull units are labelled as such and priced separately. In-stock units typically ship within 2-3 business days after payment confirmation.
