IBM - E5205 - 1.86 GHz - 6 MB L2 - Processor

IBM E5205 - 1.86 GHz - 6 MB L2 is a server-grade Intel® Xeon® processor designed for reliable dual-processor systems and workstations.

This IBM E5205, released as part of the Intel® Xeon® family, runs at a base frequency of 1.86 GHz and is built on a 45 nm manufacturing process, delivering a strong balance of performance and energy efficiency for its class.

The processor features a 6 MB L2 cache and operates in 64-bit mode, making it well suited for memory-intensive server tasks and 64-bit operating systems. Its front side bus runs at 1066 MHz, helping maintain steady data flow between CPU and memory subsystems.

With an LGA 771 (Socket J) package and a tray form factor, the E5205 is targeted at servers and workstations in the DP (dual-processor) system type and the broader server market segment. The CPU multiplier is 7 and the VID voltage range spans 0.950–1.212 V to allow stable voltage regulation under load.

Thermal Design Power (TDP) is 65 W, which helps keep cooling requirements moderate while supporting sustained server workloads. The relatively low TDP and 45 nm lithography contribute to efficient thermal and power characteristics for rack and tower servers.

Typical use cases include small to medium business servers, virtualization hosts with modest core demands, database front-ends, and computational workstations that benefit from dual-socket configurations. The E5205’s 64-bit capability and 6 MB L2 cache help accelerate multi-threaded and memory-bound applications.

Key selling points are its server-grade Intel® Xeon® lineage, 6 MB L2 cache, 1.86 GHz base frequency, LGA 771 compatibility for DP systems, and a conservative 65 W TDP that simplifies cooling and energy planning for data center deployments.
