HP ProLiant G7 c-Class server blades with Intel® Xeon® processors

Processor technologies

HP uses the enhanced technologies in Intel Xeon 5600 series processors to construct a range of

performance and power options for ProLiant G7 server blades. Xeon 5600 series processors are built

on second-generation, high-k metal gate transistors for higher performance and lower electrical

leakage.

HP engineers developed a special tool to simplify installation of Xeon 5600 series processors. HP

engineers also designed smaller, more efficient heat sinks, and precise ducting for ProLiant c-Class

server blades.

Intel Xeon 5600 series processors

ProLiant G7 server blades support up to two Xeon 5600 series processors (Figure 2). Xeon 5600

Series processors are based on 32-nanometer (nm) Nehalem microarchitecture. These processors

support distributed shared memory, Intel QuickPath Technology, Hyper-Threading technology, Turbo

Boost Technology, Advanced Encryption Standard (AES) acceleration, and Intel Trusted Execution

Technology. Compared to four-core Xeon 5500 series processors, Xeon 5600 series processors have:

 Up to six cores and a CPU frequency up to 3.33 GHz

 Improved power efficiency (up to 60% higher performance in the same power envelope)

 A shared 12MB L3 cache (Xeon 5500 series processors have an 8MB or 4MB L3 cache)

 Support for LVDIMMs (1.35V)

 Improved efficiency in Turbo Boost mode
