Features Benefits

Multi-Core Processing 

• 45nm technology boosts performance on a range of workloads.

• Increased headroom for multi-threaded applications and heavy

multi-tasking scenarios.

• Helps boost system utilization through virtualization1 and application

responsiveness.

• Quad-core performance and cost/virtual machines.

• Platform-compatible with other and Intel® Xeon® processors for ease

of migration and IT stability.

Enhanced Intel® Core™

Microarchitecture

• Boosts performance on multiple applications/user environments

and data-demanding workloads, while enabling denser data center

deployments through improved performance per watt.

• The new 45nm Enhanced Intel Core microarchitecture delivers

up to 35% more performance in the same platforms and at the

same power consumption.7

• Reduced idle processor power, lowers average server power consumption.

Large 12 MB of on-die L2 Cache

(2 x 6 MB)

• Increases efficiency of L2 Cache-to-core data transfers, maximizing

main memory to processor bandwidth.

• Reduces latency by storing larger data sets closer to the processor,

reducing the number of trips to main memory.

• Up to 6 MB of L2 Cache can be allocated to one core.

Intel® Virtualization Technology1 

• A suite of processor enhancements that assists virtualization software

to deliver more efficient virtualization solutions and greater capabilities

including 64-bit guest OS support.

• Intel® VT FlexPriority, a new Intel® VT extension that optimizes virtualization

software efficiency by improving interrupt handling.2

• Intel® VT FlexMigration enables Intel Xeon processor 5400 and 5200

series-based systems to be added to the existing virtualization pool with

single, 2, or 4+ socket Intel Core microarchitecture-based servers.

Enhanced Front-Side Bus 

• New dedicated high-speed bus design enables increased throughput

and bandwidth between each of the processors and the chipset.

• Supporting up to 1600 MHz depending on chipset.

Intel® 64 Architecture8 

• Flexibility for 64-bit and 32-bit applications and operating systems.

Eco-Friendly Manufacturing 

• Lead-free processors in 45nm high-k metal gate process technology.

• Halogen-free packaging for all Intel Xeon processors 5400 and 5200 series.
