(Impress) With a TDP of 60W to 130W, these lovely Nehalem-EP based Xeon 55xx series have hit Akiba stores. They don’t come cheap but these beasts has got the features packed to make its worth.

Specifications of these various models come in different clock rates from 2.0Ghz up to 3.2Ghz and different price ranges.

The Xeons will support the LGA1366 socket and also Tylersburg-36D (IOH) + ICH10 chipsets. Put them on a dual socket motherboard, viola! 8 physical cores and 8 logical cores!

The Xeons are boasting features with some similar to the Core I7 brothers such as:

Intel Turbo Boost – Increasing frequency and enabling faster processor speeds when conditions allow

Integrated Power Gates – Individual cores are reduced to near-zero power independent of other operating cores

Here is a breakdown of the indivudual 55xx models:
