Intel Xeon E5640 2.66GHz 4 Core 8 Threads Processor

Overview

The Intel BX80614E5640 is a Xeon E5640 processor designed for server and workstation environments where reliable multi-threaded performance is essential. Operating at 2.66 GHz with four physical cores and eight threads, it efficiently handles demanding tasks such as database management, web services, and complex computational workloads. Its 12 MB shared L3 cache reduces latency, making it well suited for virtual machines and large file operations.

Key features

• Four cores and eight threads provide strong parallel processing for multitasking and virtualization.
• 12 MB L3 cache keeps frequently used data close to the processor, improving responsiveness during heavy workloads.
• Compatible with LGA 1366 socket motherboards, allowing easy upgrades on many Intel 5500-series and older platforms.
• 80 W thermal design power supports energy-efficient operation, helping to maintain manageable rack temperatures.
• Built on 32 nm Westmere architecture, balancing performance and power consumption effectively.
• Ideal for small business servers, home labs, and extending the life of workstations without requiring a full platform replacement.
