Fusion E-350 Review: ASUS E35M1-I Deluxe, ECS HDC-I and Zotac FUSION350-A-E
by Ian Cutress on July 14, 2011 11:00 AM ESTLAN 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.
The Fusion boards don't have anything out of the ordinary in the LAN Speed test.
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.
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.
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.
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.

Regarding the Asus board not having HDMI1.4, you never seem to confirm that the others do or don't. have it. Should I assume they do or don't?"...and a Wifi card with a pair of antenna"
Antennae is the plural of "antenna." ;)
You wonder about the VGA reference in the Asus board's BIOS, but other boards clearly include a DVI to VGA adapter. Even if the Asus board doesn't include it, it could be referring to that unless it is DVI-D only. Does it support a VGA adapter?
"how overclocking effects gaming"
"Effects" should be affects.

Given these boards are clearly pushed at the HTPC usage scenario (HDMI, TOSLINK optical outputs, one of the most powerful onboard GPUs ever made, passive cooling, etc) it is very disappointing to not see any of this functionality tested out.How did they perform decoding video? Given the high CPU usage on network utilization, is there any issue playing high bitrate content from a NAS somewhere else? Can I encode? How did the GPU perform on OpenCL tasks (namely, again, content encoding)? Can the PCI-E slot take a TV tuner? What about Flash, if only for Youtube? How about upscaling low-resolution content?
And for the love of God, given two passive and one active cooling setups, how did they fare in a REAL case? Don't know many people who run their HTPCs in open-air, and the nice small cases available can be quite restrictive in terms of airflow - so will the passively cooled boards even be suitable for these? How about fan noise? It would seem Zotac and ASUS went passive because of noise concerns, so how bad was the ECS's little 40mm fan?
What about WiFi performance? You complained about one only supporting HDMI 1.3b; did the others support 1.4 (and hence 3D) perfectly? Did you test this? There was an issue with Windows' audio buffer latency - it would have been great to see this actually tested out to see if it made any difference, instead of a vague "some people might be able to hear it". Did the problematic board skip at all?
Summing up the lack of insight in the way this review was carried out.. <b>did you even test Blu-Ray playback</b>?
I'd love to see this information added to this review - I'd also be interested to know how many people you think would purchase this intending to run Metro 2033 on it.
And finally it seems your comment form is broken in Opera.

And the odd thing is when they were testing its IGP performance with Metro 2033, calling it "the Crysis of DX11 until Crysis 2 arrives, so Crysis 2 haven't been released yet? Mishmash of old and new sentences of old articles glued together. Pretty much the same thing that apoppin does on Allienbabletech and his horrible lack of focus and handbacked marketing propagandism.Plus the fact that the review has a lack of objectivity as it isnt compared to its direct rival the Atom/ION combination. I wonder who will stick a GTX 580, play games or will use it for WinRaR archiving. Atom and Fusion aren't powerhouses, are CPU's for very basic stuff and HTPC and they would had done tests in that arena, like web browsing tests, movie playback, Flash tests, USB and HD performance etc. Totally irrelevant, how low can this go?! Definitively one of the worst reviews I've ever seen.
Overall, a HTPC oriented system tested with unconventional tests against much more expensive and powerful solutions. It is like taking a Ferrari and test its performance under water and in outerspace and comparing it against the Columbia Shuttle and Navy's Nuclear Submarine. Things had gone under spiral lately and integrity has been long gone in here, a pity.

@ Ian CutressThanks for the review,
I think you touched upon a few important points like thermal performance, but as a whole, this review leaves a lot to be desired.
it is incomplete, & fails to address what the target audience of these products, wants to know.
Did this review help me decide what board to buy for HTPC use?
I'm afraid not.

It's pretty clear why the Asus BIOS mentions "VGA." The Asus and Zotac boards have DVI-I connectors, so they have extra pins for analog and work with a VGA adapters.dakky21 - Saturday, November 5, 2011 - link
I registered on this board just to say that... not ALL boards have overclock function !!!!I just bought HDC-I v1.0 yesterday, in fact only because I read it had overclock option, but what a cold shower - it does not have. At least not where it should be, under Frequency/Voltage control in BIOS.
dakky21 - Sunday, November 6, 2011 - link
To clarify, my board has BIOS version 2.10.1208 (03/24/2011) and there is NO Turbo Mode in Frequency/Voltage control. No way of getting around 33% more speed. Unfortunately, I bought this board just because of that. Never again trust reviewers or ECS...
