Centerton-based HP’s Moonshot “no match for Calxeda’s EnergyCore”

Following their recent review of the Boston Viridis, Anandtech have had their hands on HP’s new Moonshot ‘Microserver’ system based on Intel’s Centerton Atom CPUs and have drawn some interesting comparisons against the Calxeda architecture used in Viridis:

It is simple: even at 2 GHz, the Atom S1260 is no match for Calxeda’s EnergyCore at 1.4 GHz. The EnergyCore is the better server chip thanks to out of order execution, a 4 times larger L2-cache (4 MB) and the fact that it can offer 4 real cores.  Even if we assume that the 2 GHz Atom S1260 performs 8% better thanks to its higher clockspeed, it is no match for Calxeda’s EnergyCore.
