TEST RESULTS

Our test system is fairly basic, featuring a X2 4850e, a mid-level dual core processor with a low 45W TDP cooled by a stock AMD heatpipe cooler connected to a variable DC fan controller so the fan's power draw does not come into play. The rest of the system consists of a single stick of Corsair memory, an Asus Blu-ray drive, a 5400RPM notebook hard drive and an OEM Seasonic 400W power supply. The operating system used is Vista Home Premium SP1 (32-bit).

We tested the board with the CPU at stock settings with Cool'n'Quiet enabled, and underclocked to 1.5GHz and undervolted to the minimum stable voltage (0.875V).

Grey boxes indicate test failure.

At stock settings, the system idled at 30W, drew between 36W and 59W during video playback, and consumed 91W at full CPU load. Stressing the IGP with FurMark increased power consumption by a further 8W. While the GeForce 8200 chip is powerful enough to play all our test clips properly, a driver issue prevented us from playing an actual Blu-ray movie.

Cyberlink's Blu-ray Advisor utility found that the driver that shipped on the installation disc was the problem. Updating to the latest drivers from nVidia did not resolve the issue. We also tried to use ArcSoft TotalMedia Theater as an alternative player to PowerDVD, but it too failed to play our Disturbia Blu-ray disc, displaying only a black screen though the drive did appear to be reading from the disc. As it played our H.264 and VC-1 encoded clips smoothly, we would say it is technically capable of playing any Blu-ray disc, but for the moment, driver issues make it impossible. This may well be fixed at a later date.

Underclocked and undervolted, power consumption dropped dramatically, but the ability to play our VC-1 test clip was compromised. VC-1 playback was plagued by dropped frames and out-of-sync audio. 1.5GHz just didn't seem to be enough.

Compared to Zotac and Intel's LGA775 mini-ITX boards (paired with an E7200 processor), the GeForce 8200-ITX is less efficient, except in idle or with the lightest of loads. When a significant amount of CPU or IGP work is required, either Intel platform, despite having a higher TDP CPU, is far more efficient, using around 30W less power altogether.

On the AMD side of the playing field it was a different story. Compared to the Gigabyte GA-MA74GM-S2, the most efficient mATX AMD board we've tested to date, Zotac's 8200-ITX was downright frugal, using 22W less playing H.264, 13W less playing WMV-HD, and 7W less playing VC-1. Full CPU and GPU load results were similar though.
