The Intel Xeon E7 v2 line of server CPUs will have up to 15 cores built on the Ivy Bridge architecture. The new chips are targeted at the most intense applications including "high-uptime servers with up to 32 sockets, which typically handle enterprise applications such as databases, analytics tools and enterprise resource planning (ERP) software." A number of improvements including increased memory throughput due to more data transfer lanes and up to 1.5TB of memory capacity per socket help to make these the most powerful server processors available from Intel. Intel will offer 20 varieties of the new Xeons that will run from 1.4GHz to 3.8GHz with power use ranging from 40W to 150W.
