Intel Xeon E5640 2.66GHz 4 Core 8 Threads Processor

The Intel BX80614E5640 is a Xeon E5640 processor created for administrators and builders who need dependable performance in a server or workstation. Running at 2.66 GHz, it offers four physical cores and eight threads, so database queries, web services, or complex spreadsheets can run side by side without slowing one another down.

A 12 MB shared L3 cache keeps frequently accessed data close to the cores, trimming latency when you open large files or spin up virtual machines. The processor fits an LGA 1366 socket, making it a straightforward drop-in upgrade for many existing Intel 5500-series boards and older enterprise platforms.

Built on Intel’s 32 nm Westmere architecture, the chip balances computing muscle with a modest 80 W power draw. That efficiency helps keep rack temperatures under control and leaves headroom for additional drives or memory. Whether you maintain a small business server, experiment with a home lab, or extend the life of a graphics or engineering workstation, this Xeon gives you the parallel throughput you need without a costly platform overhaul.

Virtualization is another natural fit. With eight logical threads, you can dedicate resources to separate virtual machines for testing, development, or lightweight production workloads while maintaining snappy response times for each guest.
