Intel did not release the clock speeds but indicates that the processor includes 2.3 billion transistors. The Nehalem architecture integrates the memory controller and QuickPath Interconnect technology that makes connections between interconnection hearts. On the market, the Nehalem-EX will face and AMD processor 12-core Magny Cours. It is not yet cleared that the processor is burned at 45 nanometres (1 nm = 10^-9m) allowing the core to manage two tasks at a time for data treatment and up to sixteen simultaneous tasks.

IBM outpaced its competitors by announcing that three of its servers eX5 (X5 System x3850, System X3690 X5 and BladeCenter HX5) will be equipped with Nehalem-EX.
