ECS LIVA x2 Review: A Compact & Fanless Braswell PC
by Ganesh T S on August 24, 2015 8:00 AM ESTNetworking and Storage Performance
We have recently started devoting a separate section to analyze the storage and networking credentials of the units under review. On the storage side, one option would be repetition of our strenuous SSD review tests on the drive(s) in the PC. Futuremark's PCMark 8 has usually helped us avoid that overkill, thanks to a storage bench where certain common workloads such as loading games and document processing are replayed on the target drive. Unfortunately, our LIVA x2 sample (which started with 18 out of 22.4 GB free upon fresh boot and ended up with around 8 GB free after installing all the Windows 8.1 updates) consistently errored out when running the storage bench (likely due to the non-availability of enough free space in the primary disk). In order to get an idea of the performance of the eMMC storage, we ran a couple of artificial benchmarks, ATTO and CrystalDiskMark, on the OS drive.
The numbers are not as good as even an entry level SSD, but, given the price of the system, it is hard to complain. Users must keep in mind that the choice of eMMC storage and soldered main memory makes it closer to a tablet rather than a full-fledged expandable PC. In particular, one should not expect to install a large number of programs as space is likely to run out. eMMC also requires some free space to keep operating efficiently.
On the networking side, we restricted ourselves to the evaluation of the WLAN component. Our standard test router is the Netgear R7000 Nighthawk configured with both 2.4 GHz and 5 GHz networks. The router is placed approximately 20 ft. away, separated by a drywall (as in a typical US building). A wired client (Zotac ID89-Plus) is connected to the R7000 and serves as one endpoint for iPerf evaluation. The PC under test is made to connect to either the 5 GHz (preferred) or 2.4 GHz SSID and iPerf tests are conducted for both TCP and UDP transfers. It is ensured that the PC under test is the only wireless client for the Netgear R7000. We evaluate total throughput for up to 32 simultaneous TCP connections using iPerf and present the highest number in the graph below.
In the UDP case, we try to transfer data at the highest rate possible for which we get less than 1% packet loss.
The Realtek 8821AE 1x1 802.11ac / BT 4.0 combo is no stranger to our testbed. We have seen it before in our GIGABYTE BRIX Pro as well as BRIX Gaming reviews. It is also the same WLAN card used in the ASRock Beebox. Unfortunately, the performance of the mPCIe card in the LIVA x2 is similar to that of the Beebox, and nothing to write home about - this could be due to a number of factors such as host CPU limitations (Braswell vs. Core-series) and/or antenna placement.

"Even though this is a power virus test, the chassis temperatures reach an uncomfortable 75 C. ECS has taken the unenviable task of providing passive cooling for a 6W TDP SoC in a plastic chassis, and the problems are evident. It is likely that a chassis design similar to that of the Zotac C-series nano units (with perforations all around) could help with this aspect."Maybe. I found the Zotac CI320 to have a 60+ min thermal tail with steady state idle temp of 50C. Perhaps a solution with both the perforated case of the Zotac and the better heatsink of the Liva would cut it. I think 6W TDP is the limit of what you can put in a plastic case. Beyond this, you need a metal case plate or a fan.
Thanks for the review.

Can you please review the Liva Core, next?hojnikb - Monday, August 24, 2015 - link
I wish someone made Core M PCs. Silvermont is okay for light tasks, but thats about it.And Core M could be easily passivly cooled.

ECS makes the Liva Core. It has a passively cooled Core M.johnsonx - Tuesday, August 25, 2015 - link
Recently sold some MSI Cubi systems to clients, really nice. All use Haswell SoC's, commonly available are dual-core 1.5Ghz Celeron, 1.9Ghz Pentium, and 2.0Ghz Core i3 with Hyper-threading. They do have fans, but are VERY quiet.nathanddrews - Monday, August 24, 2015 - link
AMD really needs to get new Carrizo (non-L) into this category if they can. It would be HTPC and light gaming PERFECTION.V900 - Monday, August 24, 2015 - link
Having looked into both Bay Trail as well as Braswell recently when I wanted a passively cooled mini PC, I came away pretty disappointed with Braswell.The unfortunate truth is, that despite the Braswell N3050/3150 being a 14nm part, and the Bay Trail J1800/1900 a 22nm part, in most use cases the Bay Trail is faster than the Braswell.
Most users would be better off getting the older Bay Trail system with the dual core J1800 CPU or the quadcore J1900. Why?
First of all Intel cut down power usage TOO MUCH. So much that it impacts performance. The Bay Trail parts have a 10W TDP, and manage to be cooled passively just fine. The Braswell parts have 4/6W TDP, and if you want to know where Intel found the additional Watts, look at the base clock.
The Braswell parts turboclock to just over 2GHZ, but the rest of the time they skip along at a pretty slow 1.6 GHZ.
The Bay Trail quadcore part on the other hand has a base clock of 2 GHZ but turbos up to 2.4, whereas the dualcore J1800 has a base clock of 2.4 GHZ, and turbos up to 2.6 GHZ.
That's why the Bay Trail parts are faster at most tasks then the newer Braswell. If you look at some of the reviews you'll see how they handily beat them in most benchmarks...

i cant see the point of any of these low power soc no matter what purpose , if it doesn't have avx/2 ( and none of these do) and at least quad cores its no better than the other 2006 sse4 simd available since Penryn then its already obsolete , IMO not even really good enough for the bargain basement generic £20 wifi router in 2015V900 - Monday, August 24, 2015 - link
You're being waaay to performance-snobbish here.Don't see the point? It's 2015 man! Intel has squeezed so much performance out of X86 that these their cheapest CPUs are fast enough for most people.
They're fine for everyday computing tasks, as long as your needs are just basic web surfing, YouTube/movie playing and light Office work.
My dad uses one for the above. Yeah, he could have gotten something with an i3 or i5 but he wanted something quiet, and for most tasks the speed difference is barely noticeable.
They also have plenty of horsepower (and Intel quicksync video) to be a nifty and silent media center. And really cheap too. You can get one an embedded CPU, mini Itx motherboard and 4gb ram, for less or right around a hundred dollars.

see below for the many of the 5v/2A arm boxes that have real HDMI2 at 60fps HW/SW playback of UHD1 content....as long as intel do not provide the 2015 options (avx2 ,HDMI2/UHD1/60P etc instead of 2006 simd etc) on these low power SOC they will never pass the profitable ARM quad/octacore UHD compliant boxes we can buy right now....
