Intel Intel® Xeon® Processor E5603 (4M Cache, 1.60 GHz, 4.80 GT/s Intel® QPI)

**Performance. Efficiency. Agility.**

Intel’s newest dual-core processor for dual processor (DP) servers and workstations delivers a new level of energy-efficient performance from the innovative Intel® Core™ microarchitecture, optimized for low-power, dual-core, 64-bit computing.

**Dual-core processing**

Significant performance headroom, especially for multi-threaded applications, helps boost system utilization through virtualization and application responsiveness.

**Intel® Core™ microarchitecture**

Better performance on multiple application types and user environments at a substantially reduce power envelope.

**Majority of SKUs at 65W**

Significantly lower power (compared to previous generation) helps improve data center density and power/thermal operating costs.

**Ultra-dense, ultra low-power SKUs at 40W**

Low-voltage SKU available at reduced power envelopes will deliver even higher performance per watt — helps reduce power/thermal operating costs and improve data center density.

**4 MB shared L2 cache**

Increases efficiency of L2 cache-to-processor data transfers, maximizing main memory to processor bandwidth and reducing latency.

Entire L2 cache can be allocated to one core.

**1066 and 1333 MHz system bus**

Faster system bus speeds than previous generations for increased throughput.

**Intel® Virtualization Technology**

New processor hardware enhancements that support software-based virtualization, enabling migration of more environments — including 64-bit OSs and applications — to virtual environments.

**Intel® Extended Memory 64 Technology (Intel® EM64T)**

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

**Enhanced Intel® Speedstep™ Technology**

Helps reduce average system power consumption and potentially improves system acoustics.
