About AMD Opteron X3421

The AMD Opteron X3421 is a quad-core processor with four threads, featuring a base clock of 2.10 GHz and a turbo frequency of 3.40 GHz. This chip operates within a 15W TDP and uses the AMD Socket FP4, targeting dense, power-conscious server deployments. Manufactured on a 28 nm process and released in June 2017, it represents the Opteron generation focused on efficient microserver and embedded workloads. In a score overview, potential buyers should note that no benchmark data is available for direct performance comparisons, so expectations must be set conservatively. Without quantitative metrics, competitive positioning is assessed by core count, thermal budget, and socket compatibility rather than raw throughput. Compared to higher-TDP X86 parts, the AMD Opteron X3421 emphasizes efficiency and integration, making it suitable for edge nodes, storage controllers, and lightweight virtualization. For upgrade considerations, evaluate workload sensitivity to single-thread turbo, memory capacity, and I/O bandwidth, as the 28 nm process and 15W envelope limit headroom for sustained heavy compute. If your environment demands more performance, plan a platform migration to newer socketed or embedded families with higher IPC and lower power per core, while confirming BIOS and OS support for the AMD Opteron X3421 replacement.
