LAN Speed Test

LAN Speed Test is a freeware program designed for testing the network connection between two PCs on a home network.  The speed of the transfer is limited by the lowest common denominator on the network, so if you have gigabit Ethernet capable computers but a 100 Mbit capable router, you are limited to 100 Mbit transfer.  Note that this is really a formality – if a network port is rated at 1 Gbps, then chances are that it will hit at least 90+% of this value.  The main test here is CPU usage, and how much is offloaded by the controller.  For this test, we use LAN Speed Test to transfer a 1000 MB file across a home network with a 100 Mbps lowest common speed to the same machine each time, in a read/write scenario.  CPU usage is taken as a visual max/average from task manager.

LAN Speeds

The Fusion boards don't have anything out of the ordinary in the LAN Speed test.

LAN CPU Usage

Due to the E-350 CPU in the Fusion boards, transferring data across the network is actually a CPU intensive task, with most boards having a substantial CPU usage.  The Zotac has the lowest average CPU usage, but the ASUS has the lowest peak.  The ECS board performs badly here, though.

USB Speed

For this benchmark, we run CrystalDiskMark to determine the ideal sequential read and write speeds for the USB port using our 64GB Patriot SuperSpeed USB 3.0 drive.  Then we transfer a set size of files from the SSD to the USB drive, and monitor the time taken to transfer.  The files transferred are a 1.52 GB set of 2867 files across 320 folders – 95% of these files are small typical website files, and the rest (90% of the size) are HD videos.

USB Copy Performance

Across the USB tests, the Zotac underperforms by quite a considerable margin.  I redid the tests, and then got in touch with Zotac regarding this issue.  I was given a new BIOS, but this did not improve the results.  The ECS board has the best USB performance out of the three A50M boards.

SATA Testing

We also use CrystalDiskMark for SATA port testing.  The operating system is installed on the Micron RealSSD C300, which is rated at 355 MB/s read and 215 MB/s write, and the sequential test is run at the 5 x 1000 MB level.  This test probes the efficiency of the data delivery system between the chipset and the drive, or in the case of additional SATA ports provided by a third party controller, the efficiency between the controller, the chipset and the drive.

SATA 6 Gbps Sequential Speeds

Using the Micron C300, the ECS board outperforms the other two in sequential writes and reads.

DPC Latency

Deferred Procedure Call latency is a way in which Windows handles interrupt servicing.  In order to wait for a processor to acknowledge the request, the system will queue all interrupt requests by priority.  Critical interrupts will be handled as soon as possible, whereas lesser priority requests, such as audio, will be further down the line.  So if the audio device requires data, it will have to wait until the request is processed before the buffer is filled.  If the device drivers of higher priority components in a system are poorly implemented, this can cause delays in request scheduling and process time, resulting in an empty audio buffer – this leads to characteristic audible pauses, pops and clicks.  Having a bigger buffer and correctly implemented system drivers obviously helps in this regard.  The DPC latency checker measures how much time is processing DPCs from driver invocation – the lower the value will result in better audio transfer at smaller buffer sizes.  Results are measured in microseconds and taken as the peak latency while cycling through a series of short HD videos - under 500 microseconds usually gets the green light, but the lower the better.

DPC Latency Maximum

Due to the E-350 CPU, the DPC Latency results of these boards seem a lot worse than the Cougar Point boards we've tested this year.  In reality, not many of us will notice this difference.

*A small note about the Zotac board - every thirty seconds or so, a DPC spike is observed around 6000 microseconds.  This could seriously be an issue if audio is important to the users of this board - after retesting the board and contacting Zotac, they have not pinpointed the issue yet, but as I understand it, are working on a fix.

    I have the AsRock board. I get 18w idle and 24w under load via a killawatt device. Granted it uses an 80w power supply, but I'm kinda wondering how you got 59w for something that is practically the same setup in each board.
  • IanCutress - Thursday, July 14, 2011 - link

    I was using a less than ideal power supply for the power draw tests which was very inefficient in this range (<20% of maximum power), and unfortunately I don't have anything more appropriate at hand to test with. The comparisons (I believe) between the boards are more than relevant though. I will hopefully rectify this in future reviews of lower powered systems.

    Why didn't you wait to do power consumption tests then?
  • bah12 - Thursday, July 14, 2011 - link

    While not ideal, I'd say the whole point of this article was to illustrate the differences in the boards. Thus as long as they all suffered from the same inefficient PS, the information is not useless in that you can still draw a conclusion based on the differences at the board level. All and all, not ideal but useful.

    I once tried to reason with the fanboys at AMDZone on Anands behalf, defending that the reviews here were objective... I think I'm starting to believe that their might be some truth in their beliefs that the odds are stacked against AMD when their products are reviewed on here.

    At best, this review is a misguided. It focuses far too heavily on areas these systems are not aimed at, misinforms (or fails to inform) on areas that it's market are interested in and answers stupid questions that no-one is asking. Testing a GTX 580 with an E-350 at 4x PCI-E... really? Why not test out how well these work as a HTPC compared to something like ION and the latest Atom?

    At worst, this review could almost be seen as a deliberate undermining of a technology that's potentially superior to it's Intel's offering and how often could you honestly say that since Core2?. Most of the tests are irrelevant (or become irrelevant when comparing to much higher TDP chips), the one test you did manage to do which is very relevant (power consumption) was so high that it prompted me to look at other reviews and take the time to write this comment!

    This review has idle power consumption as at least 36w, Xbit have it at 7.3w even with a 880w PSU. One of these reviews has it very wrong, I know which one I'm more inclined to believe.

    I have to agree with your assessment of the review.

    - These boards are aimed at HTPC market, but the review was focused...elsewhere (frankly, I can't tell what the focus was).
    - How is the audio quality? I was very interested in the ASUS board until I noticed it doesn't have 6-channel direct out. This is important!
    - Another, less important, point: The features/specs for each board should come first. Double points for a feature comparison table.

    It is extremely unfortunate that Anandtech has sacrificed their integrity when it comes to reviewing some of AMD's products. I really hope that more and more people are made aware of what is going on, these reviews are downright dishonest.

    The most important question people need to ask is, why is this happening? What is the incentive for Anandtech.com to publish these misleading reviews?
  • ET - Saturday, July 16, 2011 - link

    Can you explain what is dishonest or misleading about this review? I agree that it could be better, but I don't see anything to indicate that anything was falsified here.
  • medi01 - Sunday, July 17, 2011 - link

    Seriously?

    Cough "This review has idle power consumption as at least 36w, Xbit have it at 7.3w even with a 880w PSU. ", cough?

    Oh, it's irrelevant, because we're comparing motherboards of the same platform? Orly? What if I read this, say "OMG it consumes so much energy" and go buy Atom?

    Tell me how to get that 36w idle thing, what kind of PSU should be used, to justify 7.3w (with bloody 880w PSU!!!!) vs 36w please?

    What are 5850 580gtx doing in this review?

    Shameless...
  • Finraziel - Thursday, September 1, 2011 - link

    Monstrously late reply... but I just can't not leave this comment... Did any of you actually read the xbit article? Those power draw measurements are measured between the PSU and the components, only measuring what the components are actually using, completely ignoring the efficiency of the PSU (the way xbitlabs has been testing for years I might add). So the fact that they were using an 880W PSU has absolutely zero bearing on their readings.
    Granted, it's still a shame that these boards couldn't have been tested with something like a pico psu, and I do agree the article could have been better (for instance, how much noise does that tiny fan on the ECS board actually make? apart from an easily missed remark in the conclusion nothing is said about it), but it's not as bad as you people are making it out to be.
