About AMD Opteron 146

The AMD Opteron 146 (AMD) belongs to the early SledgeHammer core family built on a 130 nm process and launched in September 2003. It operates on the AMD Socket 940 platform, which was the standard for early Opteron servers and workstations. With a single core and a single thread, the processor runs at a base frequency of 2.0 GHz and draws 89 W of power. Its generation places it among the first generation of AMD’s 64‑bit server CPUs, targeting entry‑level multi‑socket environments. The design emphasizes reliability and cost‑effectiveness for workloads that do not demand high parallelism.

In benchmark suites of the early 2000s the AMD Opteron 146 (AMD) delivered modest single‑core performance, often trailing contemporary Xeon counterparts but offering competitive price‑to‑performance ratios. Real‑world server tests showed it handling typical web and database tasks adequately, though its limited core count restricted scaling for heavily threaded applications. Memory latency and bandwidth were typical of the era, with support for DDR SDRAM delivering acceptable throughput for its class. Power consumption of 89 W made it a relatively efficient choice for dense rack installations of the time. Overall, the chip’s performance profile reflected its positioning as a budget‑friendly entry point into AMD’s 64‑bit server ecosystem.

The price bracket for the AMD Opteron 146 (AMD) at launch positioned it below premium Xeon models, appealing to small‑to‑medium enterprises seeking affordable server upgrades. Upgrading from an older generation required compatible motherboards on the Socket 940 platform, limiting flexibility but allowing cost‑effective retrofits. For users considering a migration, evaluating the total cost of ownership including power, cooling, and potential need for newer hardware was essential. Although superseded by newer Opteron and later EPYC processors, the chip remains a nostalgic reference point for legacy system maintenance. When assessing upgrade paths, administrators should weigh the benefits of higher core counts and newer instruction sets against the expense of a full platform refresh.
