Energy Efficiency Comparison (externally powered systems)

The ML100G-10 is one of the more energy efficient NUC/SFF PCs under light load, idling at just 7W and using 9~10W when playing high definition video. Fanless systems typically consume more power due to higher temperatures (which results in lower power efficiency) but it's effectively canceled out by using a low power processor. CPU usage during playback is about 14% playing local H.264 content, and around 25% playing Flash.

The Celeron N2930 doesn't pack much of a punch but its 7.5W TDP is certainly advantageous. Under heavier loads, it beats every recent mini PC we've tested, edging out the J1900-powered ML210G-10 by 1~2W in every test.

Ambient temperature: 20°C.

With such an extensive heat dissipation area outside the case, CPU cooling is a complete non-issue. Even when stressed far beyond the limit of normal operation using Prime95 and FurMark, the average core temperature stabilizes at 45°C at room temperature, so the processor runs at optimal speed with no risk of throttling. The warmest point on the exterior tops out at 44°C which is low enough that a bare hand can be comfortably placed on top of the unit for an indefinite amount of time.

The SSD is a bit of a concern, as 64°C isn't far off from its rated maximum operating temperature of 70°C, but this is during an extraordinary stress load that would never occur in real life. It's also possible that the Transcend model used simply runs hot. Previous review samples from Logic Supply used Emphase mSATA drives.

Boot Performance

For boot performance we record the time required to reach the Windows 7 loading screen (we stop here because this is the point where the speed of the drive becomes a factor). Prior to this test, the BIOS/UEFI is optimized by setting the hard drive recognition and other delays set to minimum, taking care not to disable common functionality like full USB support, POST messages, etc.

Like many SFF systems, the ML100G-10 boots up quite quickly, hitting the Windows 7 loading screen in under seven seconds. Depending on how quickly the display wakes up from sleep, you may not see the POST screen at all.

Wireless Performance

Our wireless performance test is a simple timed 700MB file transfer both ways to a gigabit-connected desktop on our lab's 802.11n network. There's nothing special about our setup as it consists of basic consumer networking gear.

The included Intel Dual Band Wireless-AC 7260 adapter is surprisingly fast, attaining an average transfer speed of about 80 mbps both up and downstream which easily surpasses every other wireless controller tested in our lab.
