14 DAY TRIAL // AMD has been pretty quiet until now when it comes to talking about the Opteron 4200 series of server processors based on the Bulldozer architecture, but a recent leak has managed to reveal the names as well as the specifications of these upcoming CPUs.
All the Opteron 4200 processors are based on the Valencia core and are meant to be used in dual-socket server systems.
Just as their desktop counterparts (the FX-Series) these CPUs carry three or four Bulldozer modules for a total of six or eight processing cores.
Judging from the information uncovered by CPU-World, the initial Opteron 4200 CPU batch will include eight SKU, including standard-, mid- and low-power microprocessors.
For now, AMD will release a single energy-efficient chip, the Opteron 4256 EE, which has eight processing cores clocked at 2.5GHz fitted inside a 32 Watt ACP (Average CPU Power).
The ACP rating used by AMD is lower than the TDP estimate utilized by others in the industry, so the Opteron 4256 EE should actually carry a 35W TDP.
Together with the energy efficient 4256 EE, AMD also introduced two mid-power Opteron processors, the 4228 HE and the 4274 HE, both of these carrying a 50W ACP which should be the equivalent of a 65W TDP.
The first one of the two chips includes six processing cores clocked at 2.8GHz, while the later is an eight-core CPU with a 2.5GHz base clock frequency.
The remaining five processors Opteron 4200 processors uncovered are all standard voltage parts with an ACP of 75W (95W TDP) and feature either six or eight processing cores with frequencies ranging between 2.7GHz and 3.3GHz.
No information regarding the release date of these Opteron 4200-series server CPUs is available at this time, but they should arrive in Q4 of 2011, most probably together with the first Opteron 6200 parts.
