Features Benefits 

Quad-core processing 

• Maximizes performance and performance/watt for greater performance per square 

foot for data center infrastructures and highly dense deployments. 

• Increases performance and threading headroom for multi-threaded applications and 

heavy multi-tasking scenarios, plus helps boost system utilization through virtualization
and application responsiveness.

Intel® Core™ microarchitecture 

• Better performance on multiple application types and user environments, while reducing

cooling challenges, enabling more capable, denser data center deployments.

Large 8 MB of on-die L2 cache

2

• Increases efficiency of L2 cache-to-core data transfers, maximizing main memory to

processor bandwidth and reducing latency. 

• Up to 4 MB of L2 cache can be allocated to one core. 

1066 and 1333 MHz system bus 

• Fast, dedicated front-side buses for increased throughput. 

Intel® Virtualization Technology

4 

•  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 Quad-Core Intel® Xeon® processor 5300

1,5

includes new Intel® VT

extensions around interrupt handling that will further optimize virtualization software 
efficiency.

Intel® 64 architecture

7

• 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.
