Intels eight-core Codename Nehalem is Designed to take advantage of advances in 45nm hafnium-based hi-k metal gate transistors and related manufacturing technology, eight-core, 16-thread Xeon processor manufactured chip designed for dual-socket workstations and servers, eight-core processor will use Intel's Quick Path Interconnect, eliminating the front-side bus and allow more data to flow between the processor and the other components installed in the system also include an integrated memory controller as well.and An 8-core 16-thread enterprise Xeon processor has 2.3B transistors in 9M 45nm CMOS,having latest technology of I/O links the use per-lane TX and RX compensation to enable operation up to 6.4GT/s. Vertical and horizontal splines keep the undercore clock skew under 19p before engaging the compensation. Core and cache shut-off techniques are used to minimize leakage.
