Maximize performance, 
performance/watt, and data 
center density with the industry’s
first quad-core technology
With 4 cores, large 8 MB of on-die L2 cache,
2
and the performance-enhancing and energy-
efficient technologies of the Intel Core microar-
chitecture, the Quad-Core Intel Xeon processor
5300 series helps IT departments maximize
performance and density with fewer cooling
challenges. Many server applications are well-
threaded as a result of years of running in 
symmetric multi-processing environments.
Well-threaded server applications will benefit
from more cores, larger cache, and higher
throughput and memory capacity of Quad-
Core Intel Xeon processor 5300 series-based
servers and the Intel Core microarchitecture.

Platforms based on the Quad-Core Intel Xeon
processor 5300 series also support many
Intel® advanced server technologies that help
companies enhance operations, reduce costs,
and improve business continuity: 
• Intel® Virtualization Technology
4
(Intel® VT) 
provides hardware assistance to virtualiza-
tion software, increasing its efficiency and
enabling new capabilities including 64-bit
guest OS support. The new Quad-Core Intel
Xeon processor 5300
5
includes new Intel VT
extensions to further optimize and acceler-
ate virtualization on Intel® architecture.
• Intel® I/O Acceleration Technology
6
(Intel®
I/OAT) provides, hardware- and software-
supported I/O acceleration that significantly
improves data throughput. 
A More Efficient Data Center
Two-processor platforms based on the Quad-Core Intel® Xeon® processor 5300
1
series and the Intel® Core™ microarchitecture help companies maximize data
center performance and density, while reducing cooling challenges. Platforms
based on Intel’s new quad-core technology make it easier to deliver more
business services in existing facilities, or condense applications for more 
efficient operations at lower total cost of ownership (TCO). 
Two-processor platforms based on the Quad-Core Intel Xeon processor 5300
series deliver 8-thread, 32- and 64-bit processing capabilities with 8 MB of L2
cache per processor,
2
providing more computing for threaded applications in a
variety of deployments. The Quad-Core Intel Xeon processor 5300 series is 
ideal for the densest of computing environments where best performance 
and performance per watt are key requirements. Supported by the Intel® 5000
chipset family and Fully Buffered DIMM (FBDIMM) technology, Quad-Core Intel
Xeon processor 5300 series-based platforms are expected to deliver break-
through performance with better power efficiency, delivering up to 1.5 times 
the performance compared to leading Dual-Core Intel® Xeon® processor 5100
series in the same power envelope and up to 2.4 times the performance
compared to the best published results of AMD Opteron* Model 2222.
