What the Xeon X6550 is
The Intel Xeon X6550 is an eight core Nehalem-EX part from March 2010. It runs eight Beckton cores at 2.0 GHz base with Turbo Boost to 2.4 GHz, with Hyper-Threading for sixteen threads. Cache is 18 MB of shared L3 on a 45 nm process. Power is rated at 130 W.
The X6550 brings eight cores to two socket nodes in the 6500 line, while X7550 does the same for eight socket nodes. Against the L7555 it trades power for base speed at the same cache. QPI links scale large virtualization hosts.
Memory is DDR3 ECC in four channels per socket.
Socket and motherboard compatibility
The Xeon X6550 fits LGA 1567 with 1567 lands. Boxboro 7500 boards boot it natively.

Memory, PCIe and cooling
Memory is DDR3 ECC in four channels per socket.
QPI links scale multiprocessor nodes, with PCIe Gen 2 from the chipset.
Cooling uses server heatsinks rated for 130 W.
Upgrade paths
On LGA 1567 the upgrade is the X7560 with 24 MB of cache on the same board. Beyond LGA 1567 a move to Sandy Bridge E7 needs a new platform.
