SeaMicro puts 768 cores into a 10U system

The new SeaMicro SM1000-64HD is an evolution of the SM1000-64 offering 1.5 times the speed but only consuming 1.25 times the power.

Each unit packs 384 dual-core Intel Atom processors and each processor can have 4GB RAM (i.e. 1.5TB in total) and can support 64 SATA hard drives for storage.

A base unit costs $237,000.00 which sounds a lot, but it's relatively cheap for that amount of compute power.

A standard 42U rack can hold 4 systems allowing 3072 cores per rack.

SeaMicro have said eHarmony and Mozilla are both using their systems.

They are open to using ARM CPUs when the right server processors are produced.
