INTEL Xeon Processor E5640 2.66 GHz 5.86 Gt/s 12MB L2 Cache

Designed for industry-leading performance and maximum energy efficiency, these versatile 1-way and
2-way 64-bit multi-core servers and workstations are ideally suited to a wide range of infrastructure, cloud, high-density, and high performance computing (HPC) applications.

Features and benefits of the Intel® Xeon® processor 5600 series

Intelligent performance

Boost performance by up to 15 times over single-core servers with processors that intelligently adapt to
your workload.

Intel® Turbo Boost Technology

Dynamically and automatically maximizes server application performance by increasing core frequencies,
enabling faster speeds for specific threads, and mega-tasking workloads.

Intel® QuickPath Technology

Scalable shared memory architecture with high-speed, point-to-point processor interconnects, plus
larger caches and larger memory for two-processor servers.

Large memory capacity

Up to 18 DIMM slots with up to 144 GB of main memory and up to 12 DIMM slots with up to 192 GB of
memory support higher performance for your data intensive applications.

8 MB shared L3 cache with enhanced smart cache

Inclusive shared L3 cache increases application performance by reducing traffic to the processor cores.

Intel® I/O Acceleration Technology (Intel® I/OAT), with Intel® QuickData Technology

Moves data more efficiently through Intel® Xeon® processor-based workstations and server platforms
for fast, scalable, and reliable network performance.

AES new instructions

Delivers robust encryption without needing additional appliances or increased performance overhead,
improving CPU performance for encryption.

Automated energy efficiency

Get 45 percent more performance? than previous generations without increasing power consumption
with servers based on next-generation 32nm process technology.

Integrated power gates

Allow idling cores to be reduced to near-zero power, independent of other cores, reducing server idle
power consumption.

Automated low-power states

Automatically put processor, memory, and I/O controller into the lowest available power states that will
meet the current workload while minimizing performance impact.

Flexible virtualization

Combine servers from multiple generations into the same virtualized server pool to extend failover, load
balancing, and disaster recovery capability.

Intel® Virtualization Technology? (Intel® VT)
- Enables more operating systems and software to run in today's virtual environments;
- Developed with virtualization software providers to enable greater functionality and compatibility compared to non-hardware-assisted virtual environments;
- Get the performance and headroom to improve the average virtualization performance over previous generations of two-processor servers.

Intel® Trusted Execution Technology?

Provides enhanced virtualization security through hardware-based resistance to malicious software
attacks at launch.
