INTEL Xeon 6128 3.40GHz CPU
The Intel Xeon 6128 is a first-generation Xeon Scalable processor (Skylake-SP family) built for entry-to-mid tier 2-socket servers and workstations. It suits buyers consolidating virtualization hosts, storage controllers, or general-purpose compute nodes where 8 cores and Hyper-Threading cover mixed workloads. Note that many figures below are provided as estimates in the source data — verify against Intel ARK and your motherboard’s QVL before purchase, since LGA 3647 platform support varies by board revision and BIOS.
Key specifications (table)
| Parameter | Specification |
|---|---|
| Model | Intel Xeon 6128 |
| Listed frequency (product title) | 3.40 GHz (as listed in product name; see clock notes below) |
| Architecture | Xeon Scalable, server-class (first-generation / Skylake-SP positioning) |
| Cores / Threads | 8 Cores / 16 Threads (typical for this class) |
| Base Clock Frequency | Approximately 2.2 GHz (estimated for this range) |
| Max Turbo Frequency | Up to around 3.6 GHz (approximate) |
| L3 Cache | ~12 MB (estimated typical cache size) |
| TDP | Approximately 105 W (estimated for this model — confirm chassis cooling accordingly) |
| Process Technology | 14 nm |
| Socket / Package | LGA 3647 (or equivalent server socket) |
| Memory Support | 6-channel DDR4 memory architecture |
| Maximum Memory Capacity | Platform-dependent (supports large ECC memory pools) |
| Interconnect (UPI) | Multiple UPI links for multi-socket scaling |
| PCI Express / I/O | High lane count for PCIe I/O expansion (server-grade) |
| Instruction Support | AVX-512, Hyper-Threading, Virtualization (VT-x / VT-d) |
| Reliability & Enterprise Features | ECC memory, RAS (Reliability, Availability, Serviceability) capabilities |
Good to know
- Compatibility: requires an LGA 3647 motherboard with a BIOS supporting first-generation Xeon Scalable CPUs; some later C621 boards need a firmware update or only support Copper Substrate (2nd-gen) parts, so check your board’s CPU support list first.
- Within the family: the 6128 sits in the Bronze/Silver tier of the first-generation Xeon Scalable lineup — a balanced core-count part below the Gold SKUs, trading cache and UPI link count for lower cost, which is often sufficient for virtualization nodes and storage controllers.
- Buying tip: for upgrades, confirm whether your platform is pinned to 1st-gen (Skylake-SP) stepping or also accepts Cascade Lake-SP refresh parts, as this determines your in-socket upgrade path before committing.
For tray and reel pricing, current stock by part number and date code, and volume discounts on bulk orders, request a bulk quotation.
