To those looking to build the biggest, baddest high-end PC around, the wait for Sandy Bridge-E was no doubt painful. But, it’s finally here, and much to our expectations, Intel has once again solidified its position as the performance leader. So let’s take a look at what it offers, and compare it to the i7-990X, i7-2600K and AMD FX-8150.
At Techgage, we strive to make sure our results are as accurate as possible. Our testing is rigorous and time-consuming, but we feel the effort is worth it. In an attempt to leave no question unanswered, this page contains not only our testbed specifications, but also a detailed look at how we conduct our testing.
If there is a bit of information that we’ve omitted, or you wish to offer thoughts or suggest changes, please feel free to shoot us an e-mail or post in our forums.

When preparing our testbeds for any type of performance testing, we follow these guidelines:
General Guidelines
- BIOS or EFI is up-to-date with latest version (could include a beta).
- CPU power options are left default in the motherboard’s BIOS or EFI.
- Internet is disabled.
- No virus scanner or firewall is installed.
- The OS is kept clean.
- Machine has proper airflow and the room temperature is 80°F (27°C) or less.
To aide in the goal of achieving accurate and repeatable results, we stop certain services in Windows 7 from starting up at boot. This is due to the fact that these services have the tendency to start up in the background without notice, potentially causing inaccurate test results. For example, disabling “Windows Search” turns off the OS’ indexing which can at random times utilize the hard drive and memory.
The most important services we disable are:
- Windows Defender
- Windows Error Reporting Service
- Windows Event Log
- Windows Firewall
- Windows Search
- Windows Update
The full list of Windows services we assure are disabled is large, but for those interested in perusing it, look here. Most of the services we disable are mild, but we go to such an extent to have the PC as highly optimized as possible.
To ease the tedium of setting up an OS for a round of benchmarking, we rely on Acronis True Image Home 2012 to restore an install that we previously setup. These images include most of our benchmarks, a minimal number of drivers (LAN, graphics), an up-to-date OS and all of our above-mentioned tweaks. Due to their complicated activation schemes, we do not include Autodesk products in these images, but instead install them after our OS is restored and all other testing is completed. We create a total of two OS images; one for AMD, and one for Intel.
Real-World & Synthetic Benchmarks
To help us deliver a well-rounded set of test results for each processor we evaluate, we use a variety of real-world applications and synthetic benchmarks.
Our current test suite consists of:
Real-World
- 7-zip
- Autodesk 3ds Max 2011
- Autodesk 3ds Max 2011 (SPECapc 3ds Max 2011)
- Autodesk Maya 2010 (SPECapc Maya 2009)
- Adobe Lightroom 3.5
- Adobe Premiere Pro CS5.5
- dBpoweramp R14
- HandBrake 0.9.5
- SPEC CPU2006
Synthetic
- 7-Zip (Built-in benchmark)
- Cinebench R11.5
- Futuremark PCMark 7
- Futuremark 3DMark 11
- POV-Ray 3.70
- Sandra 2011 SP5
- Sid Meier’s Civilization V
Most tests are run twice over with the results averaged. If there is an unnatural variance between the first two runs, then we continue to run the test until we receive a result we believe to be accurate.
