Intel · Xeon 3400 · 2009 · LGA1156
The Intel Xeon X3470 is a server processor with 4 cores, released in 2009. It is part of the Xeon 3400 lineup, using the Xeon 3400 platform, and fits the LGA1156 socket. Internally, it is built on the "Lynnfield" architecture. Thanks to Intel Hyper-Threading, each core can handle two instruction streams simultaneously, yielding a total of 8 threads for improved parallelism. The Xeon X3470 has a base clock of 2.933 GHz and can boost up to 3.6 GHz depending on workload and thermal headroom. Intel manufactures the "Lynnfield" silicon on a 45nm process node. This processor supports DDR3 memory across 2 channels, up to 16GB total, with ECC support standard for data integrity in server workloads. It supports single-socket (1P) configurations, with 16 lanes of PCIe 2.0 available for storage, networking and accelerators. With a TDP of 95W, the Xeon X3470 sits in a typical power envelope for a modern desktop CPU. The cache hierarchy consists of no dedicated of L1, no dedicated of L2, and 8MB of L3 cache.
