Intel Xeon Processor 5100 Series Overview
Dual processor servers and workstations based on the Dual-Core Intel Xeon processor 5100 series deliver
energy-efficient performance, reliability, versatility, and low ownership costs at a variety of price-points.
Features Benefits
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
3
• A processor hardware enhancement that assists virtualization software, enabling more
efficient virtualization solutions and greater capabilities including 64-bit guest operating
system support. The new Dual-Core Intel® Xeon® processor 5100
1,4
includes new Intel® VT
extensions around interrupt handling that will further optimize virtualization software
efficiency.
Intel® 64 architecture
6
• Flexibility for 64-bit and 32-bit applications and operating systems.
Demand-Based Switching (DBS) with • Helps reduce average system power consumption and potentially improves
Enhanced Intel SpeedStep® technology system acoustics.
