Opteron EE: AMD introduces 40 watt CPUs for servers
AMD's new Opteron CPUs of the EE series are said to require only 40 watt. PC Games Hardware summarizes the important technical data.
AMD's Opteron CPUs for servers and workstations are using the Shanghai core, which is based on 45 nanometer technology like the Phenom II. They are available as 23xx models for systems with two sockets and as Opteron 83xx for eightfold servers. All Shanghais have four CPU cores, 2 MiByte L2 and 6 MiByte L3 cache. Thus they bear resemblance to the Phenom II X4 9xx but are compatible with the server socket F. AMD now extends the Opteron family with twelve new models, two of which are creating a new power consumption class: The EE processors 2373 EE und 2377 EE are said to require 40 watt only.
But AMD doesn't specify the common Thermal Design Power (TDP), but a new value called Average CPU Power (ACP). This is said to represent the power consumption/Heat emission reached in everyday work and is much lower than the TDP. AMD's Opteron array can be split up into several classes: The EE models (40 watt ACP), the HE models (55 watt ACP), the SE models (105 watt ACP) and the untagged middle-class models with an ACP of 75 watt.
|Opteron 2373 EE||40 W||2.1 GHz|
|Opteron 2377 EE||40 W||2.3 GHz|
|Opteron 2379 HE||55 W||2.4 GHz|
|Opteron 8379 HE||55 W||2.4 GHz|
|Opteron 2381 HE||55 W||2.5 GHz|
|Opteron 8381 HE||55 W||2.5 GHz|
|Opteron 2387||75 W||2.8 GHz|
|Opteron 8387||75 W||2.8 GHz|
|Opteron 2389||75 W||2.9 GHz|
|Opteron 8389||75 W||2.9 GHz|
|Opteron 2393 SE||105 W||3.1 GHz|
|Opteron 8393 SE||105 W||3.1 GHz|
According to AMD the new EE CPUs reach a noticeably better performance per watt than older chips - in this discipline the 2377 with 2.3 GHz is said to be 62 percent better than the old Barcelona based Opteron 2356 (65 nm). Additional details about the new Opteron CPUs can be found in the table above and in the picture gallery.
