Core: Over View

• 4 Physical, 8 logical from H/T

• 3 channel memory

Core: Intel Quickpath Interconnect

• Intel X58 Arch

• Replaced front side bus

• Max width: 20 bit

• Max bandwidth: 16GB/s Unidirectional

• I7 920, 940– 16 bit and 4.8 GT/s = 19.2 GB/s

• I7 965XE– 16 bit and 6.4 GT/s = 25.6GB/s

Core: Nehalem

– 45nm architecture – Scalable performance for from one-to-16 (or

more) threads and from one-to-eight (or more) cores.

– Power usage

Core: EP & EX

• EP is for 2 sockets (the base layout)

• EX is for 4 and 8 sockets– Is the EP duplicated with more interconnects

Core: 3 to 2 chip solution

• Named Westmere

• Moved GPU functionality from the Northbridge onto the CPU

• Enables full disk encryption
