The AMD Opteron 4256 EE is a server processor with 8 cores, released in 2011 at an MSRP of $377. It is part of the Opteron lineup, using the Opteron 4200 platform, and fits the Socket C32 socket. Internally, it is built on the "Bulldozer" architecture. The Opteron 4256 EE has a base clock of 1.6 GHz and can boost up to 2.8 GHz depending on workload and thermal headroom. AMD manufactures the "Bulldozer" silicon on a 32nm process node. This processor supports DDR3 memory across 2 channels, 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 35W, the Opteron 4256 EE is an efficient chip suitable for modest cooling solutions. The cache hierarchy consists of no dedicated of L1, 2MB/module of L2, and 8MB of L3 cache.
8-core Bulldozer Opteron (Valencia) at 1.6GHz (up to 2.8GHz with Turbo Core) on Socket C32, launched November 2011. Valencia is the Bulldozer-based 4200 series on Socket C32 for one- and two-socket servers. It targets low-cost, power-optimised one- and two-socket servers. The EE (energy-efficient) bin is the lowest-power option in its series at 35W.
