With Intel’s recent Clarkdale processor launch, the itch to build that new HTPC is no doubt greater than ever. Not only does Intel offer a wide-range of processors, but motherboard vendors are currently offering an incredible amount of H55 models. We’re taking a look at two here, Intel’s own DH55TC and ASUS’ P7H55D-M EVO.
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 fully-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 table below lists the hardware for our current motherboard-testing machine, which remains unchanged throughout all testing, with the exception of the motherboard. Each motherboard used for the sake of comparison is also listed here, along with the BIOS version used. In addition, each one of the URLs in this table can be clicked to view the respective review of that product, or if a review doesn’t exist, you will be led to the product on the manufacturer’s website.
Intel LGA1156 Test System
|Processors||Intel Core i5-661 – Dual-Core, 3.33GHz, Stock Voltage|
ASUS P7H55D-M EVO – H55-based, 0503 BIOS (12/08/09)
Intel DH55TC – H55-based, 0026 BIOS (11/13/09)
Corsair XMS3 DHX 2x2GB – DDR3-1333 7-7-7-20-2T, 1.65v
ASUS Radeon HD 5850 1GB (Catalyst 9.12)
Intel HD Graphics (for non-gaming tests)
When preparing our testbeds for any type of performance testing, we follow these guidelines:
Because it gives a more realistic interpretation of motherboard/CPU performance, we leave all of the power-related options in the BIOS to their default selection. This means that for Intel boards, SpeedStep is left in tact, and Cool’n’Quiet for AMD-based boards.
Our Windows 7 Desktop for Motherboard-Testing
To aide with the goal of keeping accurate and repeatable results, we alter 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 slightly inaccurate results. Disabling “Windows Search” turns off the OS’ indexing which can at times utilize the hard drive and memory more than we’d like.
To help test out the real performance benefits of a given processor, we run a large collection of both real-world and synthetic benchmarks, including 3ds Max 2010, Adobe Lightroom 2.5, ATTO, PCMark Vantage, Sandra 2010, 7-Zip and more.
Our ultimate goal is always to find out which processor excels in a given scenario and why. Running all of the applications in our carefully-chosen suite can help better give us answers to those questions. Aside from application data, we also run two common games to see how performance scales there, including Call of Duty: Modern Warfare 2 and Crysis Warhead. For a synthetic point-of-view, we also use Futuremark’s 3DMark Vantage.
In an attempt to offer “real-world” results, we do not utilize timedemos in any of our reviews. Each game in our test suite is benchmarked manually, with the minimum and average frames-per-second (FPS) captured with the help of FRAPS 3.0.1.
To deliver the best overall results, each title we use is exhaustively explored in order to find the best possible level in terms of intensiveness and replayability. Once a level is chosen, we play through repeatedly to find the best possible route and then in our official benchmarking, we stick to that route as close as possible. Since we are not robots and the game can throw in minor twists with each run, no run can be identical to the pixel.
Each game and setting combination is tested twice, and if there is a discrepancy between the initial results, the testing is repeated until we see results we are confident with.
The two games we currently use for our motherboard reviews are listed below, with direct screenshots of the game’s setting screens.
Although the screenshots reflect a 1680×1050 resolution, we also test using 2560×1600.
