p>Built with Intel’s new 32nm microarchitecture, the Intel Xeon processor 5600 series automatically regulates power consumption and intelligently adjusts server performance according to application demand, maximizing both energy cost savings and performance. Featuring Intel Intelligent Power Technology, it reduces energy cost over single core servers by automatically shifting the CPU and memory into the lowest available power state.

In addition, built-in hardware-assisted virtualization technology with Intel Virtualization Technology FlexMigration (Intel VT FlexMigration) gives you the power and flexibility to virtualize different generations of Intel Xeon processor-based servers within the same virtualization pool, giving you the ability to migrate workloads to fewer servers at night to save energy.

If you’re looking for an energy-efficient processor that gives you the power and flexibility you need, upgrade to the Intel Xeon processor 5600 series.

  • newegg Intel QuickPath Technology To deliver top performance for bandwidth-intensive applications, the Intel Xeon processor 5600 series features Intel QuickPath Technology, a platform architecture that provides high-speed (up to 25.6GB/s), point-to-point connections between processors, and between processors and the I/O hub. Each processor has its own dedicated memory that it accesses directly through an Integrated Memory Controller. Intel Nehalem Microarchitecture complements the benefits of Intel QuickPath Interconnect (Intel QPI) by enhancing Intel Smart Cache with an inclusive shared L3 cache that boosts performance while reducing traffic to the processor cores.
  • newegg Intel Virtualization Technology (VT-x) Increasing manageability, security, and flexibility in IT environments, virtualization technologies like hardware-assisted Intel Virtualization Technology (Intel VT) combined with software-based virtualization solutions provide maximum system utilization by consolidating multiple environments into a single server or PC. By abstracting the software away from the underlying hardware, a world of new usage models opens up that reduce costs, increase management efficiency, strengthen security, while making your computing infrastructure more resilient in the event of a disaster.
  • newegg Intel Trusted Execution Technology Intel Trusted Execution Technology for safer computing is a versatile set of hardware extensions to Intel processors and chipsets that enhance the digital office platform with security capabilities such as measured launch and protected execution. Intel Trusted Execution Technology provides hardware-based mechanisms that help protect against software-based attacks and protects the confidentiality and integrity of data stored or created on the client PC. It does this by enabling an environment where applications can run within their own space, protected from all other software on the system. These capabilities provide the protection mechanisms, rooted in hardware, that are necessary to provide trust in the application's execution environment. In turn, this can help to protect vital data and processes from being compromised by malicious software running on the platform.
  • newegg Intel 64 Architecture Intel 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms when combined with supporting software. Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.
  • newegg Enhanced Intel SpeedStep Technology Enhanced Intel SpeedStep Technology is an advanced means of enabling very high performance while also meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep Technology switches both voltage and frequency in tandem between high and low levels in response to processor load.
  • newegg Execute Disable Bit (EDB) Intel's Execute Disable Bit function can prevent certain classes of malicious "buffer overflow" attacks when combined with a supporting operating system. Execute Disable Bit allows the processor to classify areas in memory where application code can execute and where it cannot. When a malicious worm attempts to insert code in the buffer, the processor disables code execution, preventing damage or worm propagation.

5 out of 5 eggsJust to let you know.

Pros: Everything the other guys said.

Cons: N/A

Other Thoughts: Other reviews point out that there is no heatsink included. This is very common with server chips. I would actually be surprised if you did get one when buying a server chip.

4 out of 5 eggsExcellent ROI / One small note

Pros: 1. Fast for only being 1.66 ghz
2. Excellent Power consumption for being a quad core CPU

Cons: 1. Thermal solution sold separately...

Other Thoughts: I gave this product 4 eggs due to the fact that unlike most Intel boxed CPU's the product lacks a CPU fan. While usually this is not a large issue due to aftermarket units, I failed to order a fan at time of purchase of this item expecting one to be in the box as usual. Newegg lacked any notes that the CPU did not come with the fan so ordering a non-oem CPU I expected a fan. So I ran all over town to find a cooler that would fit before I could use the system.

Just remember to order a thermal solution, it'll save you some trouble.

4 out of 5 eggsFast Processor / No Heatsink

Pros: 1. Fast for a 1.66hz CPU
2. Nehalem Core
3. 80w Thermal Design

Cons: 1. Thermal solution sold separately...?

Other Thoughts: For the price of this CPU and the speed of the CPU I'm impressed with its power. Its an excellent workhorse for a Hyper-V or VMWare test platform at home.

However make sure you purchase a thermal solution with this item. I raced all around town looking for a thermal solution so I could start the machine after I purchased it. I looked through the details about this product but I did not see anything about needing to buy one. That is why I gave it four eggs. Small detail but a useful detail.
