About Intel Xeon L5430

The Intel Xeon L5430 is a four-core processor from Intel’s Harpertown generation, built on a 45 nm process and released on September 8, 2008. It operates at a base clock speed of 2.67 GHz and features 4 threads, though it lacks hyper-threading, distinguishing it from other Xeon models of the era. Targeted at energy-efficient workstations and servers, the L5430’s 50W TDP made it a low-power alternative to more power-hungry counterparts in the Xeon lineup. Socketed in Intel Socket 771, it supported ECC memory for reliability, a key requirement for enterprise environments. Despite its age, the L5430 remains a reference point for understanding early quad-core server architectures. Its design reflects Intel’s mid-2000s strategy to balance performance and power consumption in professional-grade hardware.

Benchmark performance of the Intel Xeon L5430 reveals its capabilities in modern testing environments. Cinebench R23 multi-core results hover around 1,921 points, while single-core scores reach 271 points. Multi-core performance in Cinebench R20 is 806 points, and R15 multi-core scores hit 193 points. These numbers align with expectations for a 45 nm, non-hyper-threaded quad-core CPU from 2008, emphasizing efficiency in parallel tasks over single-threaded speed. The L5430’s performance is competitive against contemporaries like the Xeon E5400 series but lags behind modern multi-core processors. Its single-core metrics, however, remain modest, underscoring the limitations of older architectures in today’s demanding applications.

In its competitive positioning, the Intel Xeon L5430 occupied a niche for workstations and servers prioritizing power efficiency over raw performance. Priced at $562 at launch, it offered a cost-effective solution for organizations needing reliable, low-power processing. The L5430’s 50W TDP made it suitable for environments where thermal management was critical, such as compact server nodes or entry-level rendering stations. While outperformed by hyper-threaded Xeons and later-generation Core i7 processors in multi-threaded workloads, the L5430 held value in legacy systems requiring ECC memory support and compatibility with Socket 771 motherboards. Its architecture laid groundwork for future Xeon advancements, even as newer technologies rendered it obsolete for high-performance computing.

  • 4 cores and 4 threads for balanced multi-tasking
  • 2.67 GHz base clock speed with 45 nm manufacturing process
  • 50W TDP for energy-efficient operation in professional systems
  • Socket 771 compatibility with ECC memory support

For builds utilizing the Intel Xeon L5430, pairing it with an Intel 5000-series Socket 771 motherboard is essential. ECC DDR2 RAM modules enhance system stability, while SAS or SATA storage solutions provide reliable I/O for server or workstation duties. Cooling solutions should prioritize moderate airflow to manage the 50W TDP, though liquid cooling is unnecessary due to the CPU’s low thermal output. While modern components may lack compatibility, the L5430 remains viable for retrofits in legacy systems requiring Xeon-specific features like ECC support. However, users seeking higher performance should consider newer architectures, as the L5430’s benchmarks struggle to meet current multi-threaded workload demands. Its value lies in specialized applications where power efficiency and ECC memory are non-negotiable.
