Intel E3-1281v3 3.7GHz 4C CPU Server Processor

The Intel Xeon E3-1281 v3 is a quad-core processor built on Intel's Haswell microarchitecture, targeting entry-level server and professional workstation platforms. With a 3.7GHz base clock, it offers strong single-threaded performance that benefits applications where per-core speed matters more than raw core count — including database queries, web hosting, and small-scale virtualization. The 82W thermal design power keeps it within the cooling capacity of standard tower servers and workstations, making it a practical choice for environments where noise and power draw are considerations.

As a pulled processor, this E3-1281 v3 represents a budget-friendly path for upgrading or replacing CPUs in existing Xeon E3 v3-compatible systems. It is well-suited for businesses running legacy server hardware that still meets their performance needs, or for lab and development environments where the latest platform is not a requirement. Buyers should confirm socket and chipset compatibility with their specific motherboard before purchasing, as the listing does not specify the socket type — the E3-1281 v3 uses the LGA 1150 socket and is compatible with Intel C222, C224, and C226 chipsets.
