Yesterday AMD company declared about the accessibility of servers systems on base of five opteron processors with four cores, which have ACP value not more than 55 W.
AMD company proposes five models with ACP value not more than 55 W: these are three models for two-processor systems, and also two models for four- and 8 core systems. The Three first operate at frequencies from 1.7 to 1.9 GHz , While the two last are satisfied by frequencies 1.8 and 1.9 GHz. The frequency of memory controller in the model with 1.7 GHz frequency is reduced to 1.4 GHz, whereas remaining four processors have a memory controller frequency equal to 1.6 GHz.
Such processors are based on old BA stepping.
