Intel’s latest processor architecture brings a lot to the table, with the usual suspects dominating the feature’s-list: improved CPU and GPU performance, better power-efficiency, and new instruction sets. We’re taking a look at the desktop line’s highest-end offering here, so let’s see how it stacks up against the last-gen’s champ.
Test Systems & Benchmarking Methodologies
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.
The tables below list all of the hardware we use in our current CPU-testing machines.
When preparing our testbeds for any type of performance testing, we follow these 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.
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 Error Reporting Service
Windows Event Log
To ease the tedium of setting up an OS for a round of benchmarking, we rely on Acronis True Image 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. 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:
Autodesk 3ds Max 2011
Autodesk 3ds Max 2011 (SPECapc 3ds Max 2011)
Autodesk Maya 2012 (SPECapc Maya 2009)
Adobe Lightroom 4.4
Adobe Premiere Pro CS5.5
Futuremark PCMark 7
Futuremark PCMark 8
Sandra 2013 SP3a
Total War: SHOGUN 2
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.
