Introduction
Intel's latest-generation microarchitecture represents the next step in unprecedented processor performance and dynamic scalability.
Designed from the ground up to take advantage of hafnium-based Intel® 45nm hi-k metal gate silicon technology, Intel®
Microarchitecture (Nehalem) unleashes parallel processing performance enabled by Intel® QuickPath technology providing an
integrated memory controller and high-speed interconnect per independent processing core.
Performance and Features
Maximum multitasking performance Intel® Microarchitecture (Nehalem) offers the latest in processor innovation, including:
'Dynamic scalability, managed cores, threads, cache, interfaces, and power for energy-efficient performance on demand.
Design and performance scalability for servers, workstations, notebooks and desktops with support for 2-8+ cores and up to
16+ threads with Intel® Hyper-Threading Technology (Intel® HT Technology), and scalable cache sizes, system interconnects,
and integrated memory controllers.
Intel® Turbo Boost Technology delivers additional performance automatically when needed by taking advantage of the
processor's power and thermal headroom. This enables increased performance of both multi-threaded and single-threaded
workloads.
Intel Hyper-Threading Technology brings high-performance applications into mainstream computing with 1-16+ threads
optimized for a new generation multi-core processor architecture.
Scalable shared memory of Intel® QuickPath technology features memory distributed to each processor with integrated
memory controllers and high-speed point-to-point interconnects to unleash the performance of future versions of next-generation
Intel® multi-core processors.
Multi-level shared cache improves performance and efficiency by reducing latency to frequently used data.
Turbo Boost Technology
This technology now built into Xeon 3500 Series Quad-Core processors will increase the speed of your processor on demand (from
OS) if the CPU is operating below power / thermal specifications:
Benefit of Turbo Boost (how much CPU speed up) depends on number of active cores
Likelihood of Turbo Boost operation increases when less cores are active
Likelihood of Turbo Boost operation increases when dynamic power mgt is enabled
