Scientific and Synthetic Benchmarks
2D to 3D Rendering –Agisoft PhotoScan v1.0: link
Agisoft Photoscan creates 3D models from 2D images, a process which is very computationally expensive. The algorithm is split into four distinct phases, and different phases of the model reconstruction require either fast memory, fast IPC, more cores, or even OpenCL compute devices to hand. Agisoft supplied us with a special version of the software to script the process, where we take 50 images of a stately home and convert it into a medium quality model. This benchmark typically takes around 15-20 minutes on a high end PC on the CPU alone, with GPUs reducing the time.
Console Emulation –Dolphin Benchmark: link
At the start of 2014 I was emailed with a link to a new emulation benchmark based on the Dolphin Emulator. The issue with emulators tends to be two-fold: game licensing and raw CPU power required for the emulation. As a result, many emulators are often bound by single thread CPU performance, and general reports tended to suggest that Haswell provided a significant post to emulator performance. This benchmark runs a Wii program that raytraces a complex 3D scene inside the Dolphin Wii emulator. Performance on this benchmark is a good proxy of the speed of Dolphin CPU emulation, which is an intensive single core task using most aspects of a CPU. Results are given in minutes, where the Wii itself scores 17.53; meaning that anything above this is faster than an actual Wii for processing Wii code, albeit emulated.
Emulation is clearly not a target for Avoton.
Point Calculations – 3D Movement Algorithm Test: link
3DPM is a self-penned benchmark, taking basic 3D movement algorithms used in Brownian Motion simulations and testing them for speed. High floating point performance, MHz and IPC wins in the single thread version, whereas the multithread version has to handle the threads and loves more cores.
As the 3DPM test abuses the ability for a CPU to dispatch threads and FP calculations, Intel have historically been good here. The CPU battles with AMD in single threaded, but the 8 cores allows software to exploit parallelism in this manner.
Encryption –TrueCrypt v0.7.1a: link
TrueCrypt is an off the shelf open source encryption tool for files and folders. For our test we run the benchmark mode using a 1GB buffer and take the mean result from AES encryption.
For AES software encryption, the Avoton platform enjoys the 8 cores but suffers from a lack of hardware acceleration, putting it in the region of the AMD CPUs.
Synthetic – 7-Zip 9.2: link
As an open source compression tool, 7-Zip is a popular tool for making sets of files easier to handle and transfer. The software offers up its own benchmark, to which we report the result.

Yes, for that price and target market, they should have gone with an LSI chip. You don't see Supermicro or Tyan boards in that price range using Marvell.cen - Tuesday, April 29, 2014 - link
I know it was said that the actual storage review is coming in the future but I think this article is a complete waste of time. You should simply let the storage review happen and not bother with this at all. More than half of the benchmarks are useless, the only ones of value might be encryption and compression.What we actually want to see is FreeNAS thrown in there with a 16TB ZFS zpool and some IO benchmarks. :)

Could be perfect for anyone wishing to build a tiny box for virtualization, a task in which many a NIC, plenty of RAM and a multicore processor is most helpful.RandomUsername3245 - Tuesday, April 29, 2014 - link
I've wondered how one of these Avoton boards would compare to a Supermicro C2xx + Pentum G3430 (which supports ECC). This is the cheaper option if you don't need lots of ports, but once you add $100 for a sata card from Ebay, these options are similarly priced.Calista - Tuesday, April 29, 2014 - link
Could you please measure power consumption without the 770 as well? I have a HP Elite 8200 with a quad i5, SSD + 2.5" HDD, 32 GB RAM and an extra NIC as a makeshift box for ESXi and with 6-8 virtual machines running it draw less than 30 watt. It would be interesting to know how low this machine could go since any machine running 24/7 will add substantially to the power bill.Guspaz - Tuesday, April 29, 2014 - link
If I was using this in my home file server, I'd make a few changes to the board. The number of SATA ports is fine, because even though I've got 18 drives in mine, that PCIe slot lets you put in a SAS/SATA controller to get the total up as high as needed (16 port cards aren't hard to find, higher is available).However, I'd change a few things:
1) Replace the CPU. Home file servers can often be bottlenecked by individual CPU core performance, because not all filesystem operations on ZFS are multithreaded (although it's far better these days). For the ~25W TDP, I would much rather have a Haswell part, even if it meant fewer cores. For that TDP, you could get a ~3GHz dual-core part, or a ~2GHz quad-core part. Either of those would be better suited.
2) Add digital video output. HDMI, DVI, DisplayPort, any of them. I'm not suggesting using this thing for HTPC use, but many monitors these days are digital-only, and nothing is more annoying than trying to diagnose problems with a headless system when your motherboard is VGA-only and all you have is digital-only monitors.
3) Drop two of the RAM slots, and use them for another PCIe slot. Four slots is excessive for anything but enterprise use. Two slots cheaply gets you 16GB of RAM, or 32GB if you're desperate, either of which is more than enough for a home file server. A second PCIe slot, on the other hand, could enable a variety of other options, be they multiple SAS/SATA cards, a discrete video card if you really do want to use the thing as an HTPC, a video capture card (this board in that Silverstone case would probably make a decent HD-SDI recording box), etc.
4) More USB ports, prefereably 3.0. If extra space is needed for the ports, ditch one of the three GigE ports; two is plenty.
5) An mSATA slot for a boot drive could be useful, although it would probably increase board complexity by requiring some of the board components to move to the rear.

"Two slots cheaply gets you 16GB of RAM, or 32GB if you're desperate"My ZFS media rig has 19 drives (21 including the ZIL and l2arc), plus boot media and at 36Tb it _needs_ 32Gb of ram to work efficiently. It kept bottlenecking at 16Gb. The next round of storage will push well past the 32Gb requirement.
+1 on the video output, +1 on usb3 - but I don't think it needs more ports. That's not a good fit for the target, which is a storage controller. Ditto on the mSATA.
If you need fewer cores there's a quad-core version which is cheaper.
I'd prefer that they placed a lsi sas controller onboard and dumped the sata ports for minisas (an expander cable is cheap, tidy and positively locks into place to ensure no problems.) The downside is that a decent sas controller would add at least $100 and a port multiplexer as much again.
If I was designing, I'd think about 10Gb copper, but that adds 15W to the power consumption and $150 to the price.
This thing is expensive for prosumers and limited for enterprise, but compromises are always like that. Supermicro's version has similar issues and the fact that they don't use minisas makes me think that perhaps Intel have placed restrictions on what can be used.

well my zfs rig has 20 2.5" 2tb sata hdds (2x 16tb raidz2). no ZIL. no L2ARC.runs on a single 8GB ecc ddr2 dimm on a sandy bridge i3-2100T.
as a home fileserver this system rocks. it might be ram "bottlenecked" for high i/o tasks, but all i can see is that it performs at least as well as a single USB3 hdd... and it outperforms any consumer nas.

For a NAS or SAN build this seriously lacks 10GbE and USB 3 ports. All in all this board seems like a pretty strange amalgamation of random features, as there're better choices for about any possible use case around.Gunbuster - Tuesday, April 29, 2014 - link
14000 RPM Delta fans? No Thanks!I would have called it the AssRack. Sorry I couldn't resist!
