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 661-3587 ship?
If in stock, the 661-3587 ships same business day on US orders placed before 3 pm ET. Most US ZIP codes receive next-business-day or 2-day delivery via FedEx/UPS Ground or Express. Bulk and project orders shipping in pallets are typically dispatched within 24-48 hours.
The 661-3587 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.
VMware vSphere ESXi 8 Host — Per-CPU core count drives VVF/VCF licensing cost — choose 16–24 cores for cost-optimal density unless workload is core-bound.
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.
What is the 661-3587?
The 661-3587 is a Apple server-class processor with clock speed 2.3 GHz and generation Gen5, manufactured by Apple. Pro Disk Network ships this part new and certified-refurbished from our US warehouse with same-day dispatch on orders placed before 3 PM ET, backed by a 30-day return guarantee.

Pro Disk Network Buyer’s Guide: Processor Boards
Socket Compatibility, EVC Mode, and BIOS Revision Planning
Choosing the 661-3587 for a server upgrade or replacement starts with socket compatibility. CPU sockets are tied to motherboard chipsets and revisions; a board that supports Skylake-SP may or may not support Cascade Lake-SP depending on BIOS. Before ordering, look up the motherboard QVL (qualified vendor list) and confirm the 661-3587 appears with a supported BIOS version. If the BIOS needs an update, plan the flash before swapping CPUs — many systems will not POST long enough to flash with the wrong CPU installed.
AI Workloads, AMX, and the Inference Performance Story
For dedicated AI inference hosts, prioritize core count over clock speed. INT8 inference is bandwidth-bound, not frequency-bound, so a 32-core part at 2.5 GHz outperforms a 16-core part at 3.5 GHz on most LLM workloads. For mixed virtualisation + occasional inference workloads, prioritize clock speed — VDI and OLTP database workloads benefit from the higher frequency.
