About Intel Xeon E5506

The Intel Xeon E5506 is based on the "Gainestown" microarchitecture, built on a mature 45 nm process. It features a quad-core, four-thread design with a base clock of 2.13 GHz and a healthy 4 MB shared L3 cache. This chip operates within a standard 80W TDP and utilizes the Intel Socket 1366, which was the cornerstone of the Nehalem-EP platform. The design emphasizes reliability and multi-threaded throughput rather than high-frequency bursts, typical of entry-level server/workstation silicon. Its memory controller and QPI links integrate directly on-die, a hallmark of the Nehalem generation's architectural shift. In benchmark comparisons, the Xeon E5506 delivers respectable performance for its vintage, though it lags behind modern cores. In Cinebench R23, it achieves 1,666 points in the multicore test and 235 points in the single-core test. The older Cinebench R20 suite shows 699 points multicore and 98 points single-core, while Cinebench R15 yields 167 points multicore. These figures highlight the processor's strength in lightly threaded applications, where the 2.13 GHz clock is a limiting factor. Consequently, the E5506 is best suited for background rendering, virtualization, or file serving rather than high-frequency interactive workloads. When considering an upgrade or deployment, keep these points in mind: 1. The Intel Socket 1366 platform requires matching X58 or C series chipsets; ensure your motherboard BIOS recognizes Gainestown CPUs. 2. Memory configuration matters: triple-channel DDR3-800/1066 is supported, and mixing ranks or speeds can throttle performance. 3. Thermal design is straightforward keep airflow steady and use a mount rated for 80W TDP to maintain boost stability. 4. For modern workloads, compare the Xeon E5506 against 6-core/12-thread LGA1366 Xeons; the extra threads often yield a 30 40% multicore gain in R23. 5. Power efficiency is modest by today's standards; consider platform replacement if idle draw or performance-per-watt is a priority.
