SFF Roundup, Part I: Socket 478 and 754 Systems

Encoding and Network Benchmarks
For our encoding benchmark test, we used AutoGK to encode the high quality TV input from the Aopen into a 5 MB file using two passes and timed how long it took. We used both the DivX 5.2.1 and Xvid 1.0.2 with audio encoding enabled. While some might find it useful to test the video and audio encoding separately, with the assumption that SFF computers would often be used as HTPCs, we wanted to show how a real-world test runs. Video size was set to a fixed width of 640 pixels (i.e. no loss in video size) and audio was set to auto. We then timed the entire encoding process from start to finish. We have samples of the DivX and Xvid encoded video files, and when compared with the 28MB source file, you can see the benefit of re-encoding.
We also ran some rudimentary performance tests on the network connections, just to verify that gigabit Ethernet performance was reasonable. We copied a 4 GB file from one system to each computer - with both connected to a switch - and timed how long it took. Since the source computer was running a standard 7200 RPM SATA drive, we should be HDD limited, but even then GbE is still three to four times faster than 100Mb.

#21 - We're working on getting the Iwill dual-CPU system. We'll see what Iwill has to say. :)#19 - The unit reviewed was the EA65-II. There is an EA65-IIa as well as an EA65-IIa 2.0. The only difference between the IIa models is the version of InstantON included, and I believe you can download the latest version and turn the IIa into the IIa 2.0. Does that make sense? Also, I don't think the IIa is available in the US yet, but should be within the next month or two.
If you don't mind a spoiler (yeah, right), the Pentium M desktop/HTPC that I have for review is louder than the SFFs in this roundup (other than the e-bot). However, it is a fully configured and loaded system with two HDDs, a 6800GT, etc. I've checked with the manufacturer about the noise levels and will see if I can get it reduced. Right now, the HSF is really huge - it looks like a Pentium 4 HSF, which is probably overkill for the Pentium M 2.0.
On a side note, if you haven't seen the die of the Dothan, it's REALLY SMALL! About half the size of a dime. Pretty crazy to see that much power in such a small size.

Request the Iwill ZMAXdp ($675 at NewEgg) for the next SFF piece! :)GoatHerderEd - Wednesday, February 16, 2005 - link
NM, the firewire is on the front. I still thing there should be a port or two on the back though.silentcomputing - Wednesday, February 16, 2005 - link
Nice job, Jarred.I am interesting in the Aopen EA65-IIa, but got confused about the new model name. You mentioned the new model is EA65-IIa first, but followed by EA64-IIa.... Is it a typo or is Aopen going to release AMD64 version of the EA in the near future.
When do you think you can have the P-M on desktop review?? I can't wait to have one... enough for the noise from any of my computers...including Shuttle and Dell..... :(

#12, Wow, I got the Shuttle SN95G. But I really want that Iwill dual Opteron! That thing looks so sweet! No fire wire though )=#8, Why do you say the SN95G is unreliable? I think its pretty good. Boot up time isnt as fast as my Nforce2 XP 1800+, but its faster otherwise.

Now that it looks like AMD is coming out with additional Socket 754 Sempron CPU's, the Biostar really looks like a good choice. It's not like one needs huge CPU power for a HTPC, as long as it does a good job of encoding/decoding, and the Sempron should also run fairly cool. Add a Hauppauge WinTV PVR-150/250 and a discrete ATI graphics card (for additional hardware-assist MPEG-2 playback and VIVO) and it looks to be a really good choice.smn198 - Wednesday, February 16, 2005 - link
I've said it before but would it be possible to present the non-linear noise measurements on a non-linear scale?That would more accurately show that with the IGP, the foxconn is over twice as loud as the others.
Don't mean to seem critical. Great read. That is why I keep coming back.
#3. Read the first few paragraphs of the review. Besides, it is very cheap now.

"Shuttle is able to use a single fan to fool both the CPU as well as the case"I've been trying that for years but have never successfully managed to fool them both at once!

Thanks JW, Iknow it's a lot to ask.JarredWalton - Tuesday, February 15, 2005 - link
11, 12 - I'll have to see about those two units. For the Iwill, at least, they would either need to send processors or I would have to get some sent from AT HQ. I don't have any server parts at my location for testing.
