About the SX826

The Intel SX826 (SX826 - Intel 80486 25MHz 25MHz FSB 8KB L1 Cache Socket PGA168 Processor) is a Intel Unboxed Processors component engineered for sustained enterprise-class workloads. This part addresses common procurement scenarios where exact-match replacement, capacity expansion, or new-build deployment is required. Technical specifications include bus speed of 25 MHz FSB, cache of 8KB L1. Workload fit covers VMware ESXi virtualization hosts (vCPU density), SQL Server / Oracle database licensing optimization (per-core), Kubernetes container density, and HPC compute-node provisioning. Pro Disk Network sources the SX826 through reputable distribution channels and applies a verification check against the OEM compatibility matrix before each unit is added to active inventory. Each unit ships from a US fulfillment hub (Hillsboro OR, Atlanta GA, or Phoenix AZ) with same-day dispatch on in-stock orders before 3pm ET. 90-day Pro Disk Network functional warranty included; free US ground shipping on orders over $150.

Quick Answer: What socket does the SX826 use?

Confirm the socket against your motherboard's CPU support list - Intel Xeon Scalable spans LGA 3647 (1st/2nd gen), LGA 4189 (3rd gen Ice Lake), and LGA 4677 (4th/5th gen Sapphire/Emerald Rapids). A BIOS update is often required for newer steppings even on the same socket. Email sales@prodisknetwork.com with your motherboard model for a compatibility check.

How fast does the SX826 ship?

SX826 orders placed before 3 pm ET ship the same business day from US warehouses. Delivery is next business day to most metro ZIPs via FedEx/UPS overnight; ground delivery covers remaining US in 1-4 business days.

Common Use Cases for SX826

The SX826 is deployed by US enterprises, MSPs, government, and education customers across multiple infrastructure scenarios. Below are the most common deployment patterns Pro Disk Network sees in real-world orders.

  • Hyper-V Cluster Node — Windows Server Datacenter licenses by core, but Hyper-V scales linearly. Higher-clock, mid-core SKUs win for transactional workloads.
  • Citrix VDI Pool — Frequency-sensitive — prefer high-clock 16–18 core SKUs over high-core-count parts to maintain user-perceived snappiness.
  • Kubernetes / Tanzu Workers — Higher core count amortises better across many small Pods. EVC mode planning matters for live-migrate parity.
  • AI Inference Host — Sapphire Rapids and Emerald Rapids include AMX silicon for INT8 inference acceleration — meaningful uplift for BERT, ResNet, and LLM serving.

What is the SX826?

Cons

  • Older microarchitecture — not appropriate for new AI/AMX workloads
  • Not always silicon-binned for overclocking
  • Stepping mismatch with newer revisions can require microcode update

Frequently Asked Questions about SX826

Is the SX826 a genuine Intel part?
Yes. Pro Disk Network sources every SX826 as factory-original Intel inventory. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned Intel servers, surface-tested, and re-warranted by Pro Disk Network for 90 days.
What socket does the SX826 use?
Confirm the socket against your motherboard's CPU support list - Intel Xeon Scalable spans LGA 3647 (1st/2nd gen), LGA 4189 (3rd gen Ice Lake), and LGA 4677 (4th/5th gen Sapphire/Emerald Rapids). A BIOS update is often required for newer steppings even on the same socket. Email sales@prodisknetwork.com with your motherboard model for a compatibility check.
How fast does the SX826 ship?

Socket Compatibility, EVC Mode, and BIOS Revision Planning

For VMware vSphere clusters, EVC (Enhanced vMotion Compatibility) mode dictates which CPU generations can coexist in the same cluster while still supporting live migration. Adding a newer-generation SX826 to a cluster with older CPUs requires setting EVC to the older baseline, which disables newer instructions on the new CPU. Plan EVC mode at cluster creation time; changing it later requires powering off the cluster.

AI Workloads, AMX, and the Inference Performance Story

Plan memory bandwidth alongside the CPU: AMX inference is memory-bandwidth sensitive. A SX826 paired with insufficient memory channels (e.g., DDR5-4800 in fewer than 8 channels per socket) will underperform its theoretical peak by 30-40%. Confirm motherboard channel count and DIMM population before ordering.
