AMD brought out its new line of energy-efficient processors this week featuring new power management techniques designed for blade and rack servers.
The new Opteron HE quad chips offer a 55-watt thermal envelope and range in size from the 1.7 to 1.9 GHz HE 2300 series to the 1.8 and 1.9 GHz HE 8300 series. The devices are aimed at two-, four- and eight-way servers.
AMD measures its thermal envelope according to average CPU power (ACP), which is a break from traditional measurements using thermal design power (TDP), or the amount of heat that needs to be dissipated. AMD argues that ACP offers a more accurate reading given the inclusion of memory controllers and HyperTransport elements on the processor. Either way, it appears that the HE line generates significantly less heat than its existing quads.
Pricing ranges from $209 for the lower-end 2300s to $873 for the top-of-the-line 8300s.
