Test Setup:

The last AM2 motherboard we looked at specifically was the Foxconn C51XEM2AA-8EKRS2H board and that was back in December of 2006.  While we have looked at some other AM2+ motherboards since - in articles like the AMD Phenom review that featured AMDs Spider platform, this is the first AM2+ board we've reviewed and therefore don't have any current reference data.  As such we are starting fresh and we already have other AM2+ boards in queue and will compare those to the K10N750SLI-WiFi.  Below are the test system specs.

 

Subsystem Tests - HDD:

We start off the subsystem testing with some HDD tests.  During the review I had a 250GB Samsung HDD die on me so I had to start fresh and all I had extra was an older 120GB Hitachi SATA HDD.  The following tests no doubt show the limitation of the HDD - not the motherboard, but the results are still pretty good.

ATTO showed that the drive capped out at a little better than 56MB read and 55MB Write.  HDTach shows a similar result as the drive starts out over 60MB/sec at the start and manages to average 49.2MB/sec.  CPU utilization is absolutely nil and this shows that the HDD controller is working efficient.

 



Subsystem Tests - Audio:

ASRock claims that their HD Audio is capable of 110db dynamic range through the ALC890 codec.  We fired up the RightMark Audio Analyzer and took it for a spin.

We tested a few different bit and sampling rates and have posted the chart below for your viewing pleasure.

While it clearly falls shot of 110db Dynamic range, it is a lot better quality than the audio from the Intel Q35 mATX motherboard.

 

Subsystem Tests - Network:

One area that we have started testing is network performance.  It is easy for a company to claim great networking features as many users never test them out and are puzzled when they can only transfer files at a mere 250Mbit/sec on their 1000Mbit/sec NIC.  We use iperf for testing network performance and on this board we tested out both wired and wireless performance.

The K10N750SLI-WiFi comes bundled with an 802.11b/g adapter that plugs directly into a motherboard header.  The nifty thing about this feature is the included software and the 1-click ability to set up the motherboard as either a wireless client or a wireless access point.

In iPerf, we ran single threaded tests as well as a multi-threaded network test that used five streams at the same time.  Multi-threaded performance always looks better and shows how the network system will hold up when accessed from multiple machines at the same time.  Single thread performance shows client-to-client file sharing performance.

CPU load averaged 18% when running the wired tests and 10% when running the wireless tests.  CPU load is quite acceptable considering the high bandwidth that the ASRock K10N750SLI-WiFi network is capable of.  The wired performance is the best we've ever seen and the wireless performance falls on-par with what we've come to expect from 802.11g device.  It is about 37% of theoretical performance.

On the next page, we'll run some performance benchmarks and see how this board rounds out.
