Dual CPU Quad Core Intel Clovertown

VPS:

Each server is broken down into between 6 and 8 powerful VPS (Virtual Private Servers).

Each VPS is guaranteed certain resources, additionally each VPS has the ability to "burst" as follows: -

One CPU Core guaranteed, Burst to 4 CPU Cores
2 GB RAM Guaranteed, Burst to 4 GB RAM

The individual VPS are therefore extremely powerful in their own right.
