Intel · Xeon MP · 2008 · Socket 604
The Intel Xeon X7458 is a server processor with 6 cores, released in 2008. It is part of the Xeon MP lineup, using the Xeon MP platform, and fits the Socket 604 socket. Internally, it is built on the "Dunnington" architecture. It operates at a fixed 2.4 GHz. Intel manufactures the "Dunnington" silicon on a 45nm process node. This processor supports FB-DIMM DDR2 memory across 2 channels, up to 128GB total, with ECC support standard for data integrity in server workloads. It supports both single-socket (1P) and dual-socket (2P) configurations. With a TDP of 90W, the Xeon X7458 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 16MB of L3 cache.
Six-core Xeon MP, the final NetBurst-era Socket 604 chip, bridging to the Nehalem generation.
