  • newegg Intel Turbo Boost Technology 2.0 More intelligent, energy-efficient, and dynamic than previous generation, Intel Turbo Boost Technology 2.0 gives you accelerating performance when you need it. It delivers an even greater automatic speed increase by allowing processor cores to run faster than the base operating frequency for demanding applications if the processor is operating below power, current, and temperature specification limits.
  • newegg Hyper-Threading Technology (HT Technology) Today's Intel Hyper-Threading Technology (Intel HT Technology) delivers thread-level parallelism on each processor resulting in more efficient use of processor resources—higher processing throughput—and improved performance on the multi-threaded software of today and tomorrow.
  • newegg Intel Virtualization Technology (Intel VT) 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 Virtualization Technology (Intel VT) for Directed I/O (Intel VT-d) Intel Virtualization Technology for Directed I/O (VT-d) extends Intel's Virtualization Technology (VT) roadmap by providing hardware assists for virtualization solution. VT-d continues from the existing support for IA-32 (VT-x) and Itanium processor (VT-i) virtualization adding new support for I/O-device virtualization. Intel VT-d can help end users improve security and reliability of the systems and also improve performance of I/O devices in virtualized environment. These inherently helps IT managers reduce the overall total cost of ownership by reducing potential down time and increasing productive throughput by better utilization of the data center resources.
  • newegg Intel Trusted Execution Technology (Intel TXT) 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.

5 out of 5 eggsSUPER!

Pros: Run this CPU at 100% cpu for 8-10 hours a day, every day. Great cc compilation times, and superb reliability.
Even using the stock heat sink/fan this thing is a beast, with no issues whatsoever.

Cons: None?

1 out of 5 eggsShipping dept FYI

Pros: quick shipping

Cons: Processor was sent in a flimsy bubble-lined envelope instead of a box. No styrofoam or anything else to protect contents. No signs indicating FRAGILE contents. As you would imagine the item was crushed - The retail package box looked like an accordion. Have not installed it yet - waiting for motherboard. Hope they do a better job packaging that. I would expect better from NewEgg.

5 out of 5 eggsExcellent performance

Pros: Been running close to 100% constantly since we purchased it and the processor hasn't missed a beat. The integrated graphics are more than adequate for 2D Photoshop work and the like. Hyperthreading and turbo boost - makes for a good alternative to an i5 2500K for those who don't overclock.

ECC RAM compatibility is a big thing for us so the Xeon line is a must.

Cons: None significant that I can see - if you're buying a Xeon you probably aren't looking to overclock so the locked multiplier isn't really a disadvantage.

Other Thoughts: Using it with an ASUS P8B WS motherboard with no dramas.

5 out of 5 eggsGreat Server Proc w/ Integrated Graphics

Pros: + Great little server processor
+ Runs fast and handles everything I throw at it
+ VT-d support is great for VM related work
+ Embedded graphics allow me to dedicate use my video card to a VM

Cons: - None yet

Other Thoughts: I purchased this processor for a new Sandy Bridge server running Ubuntu 11.04. It's been running great since I brought the server online last weekend. Runs with both multi-core and HT support. I'm planning on using it with Xen and VT-d when Ubuntu 11.10 and the Linux 3 Kernel come out next month. Video card pass-through and gaming in a VM, here I come...

Running with the following components:
* ASUS P8B-E/4L ATX Server Motherboard
* 8GB (2 x 4GB) Kingston DDR3 1333 SDRAM ECC
* 2x WD Caviar Black 750GB 7200 RPM 64MB Cache SATAIII HD (Linux Software RAID 1)
* 4x HITACHI Deskstar 0S03230 3TB 5400 RPM SATAIII (Linux Software RAID 5)
* SuperMicro AOC-USAS2-L8i SATAIII HBA (Running IT HBA Firmware)
* AZZA Solano 1000 Black ATX Case
* Corsair Professional Series HX750 PS
* Corsair H60 Cooler

5 out of 5 eggsexcellent CPU!

Pros: Paired with an Intel S1200BTL mainboard, this CPU serves as an excellent ESXi computer. I use this platform as a supportable Cisco UC lab, and I am extremely impressed with it. I switched to this combo from another Intel desktop processor, and the difference in performance is remarkable. Despite the similar clock speeds and other stats, this CPU runs cooler, and faster. I can only attribute the better performance in VMware to the Intel-VT and the VT-d technologies. But I am seeing a 30 - 50% increase in CPU idle times compared to my previous setup

Cons: I can't think of anything...

Other Thoughts: I built this machine as a sort of Xeon workstation, and it is currently running ESXi and cisco UC applications in my lab. Judging it by the difficulties other Cisco UC labs have had getting started, I feel as I made the right choice.

4 out of 5 eggsSlightly dissappointed

Pros: Seems to work fairly well in spite of not being able to load any Asus drivers. Will only load generic drivers from Microsoft

Cons: I purchased as a combo deal on Newegg with Windows Home Server 2011 expexting to have a good match since it was a combo deal. Well if it is a match why do all the drivers on the Asus disk as well as ther web site say they do not support this operating system: WNT_6.1I_64
