ECS LIVA x2 Review: A Compact & Fanless Braswell PC
by Ganesh T S on August 24, 2015 8:00 AM ESTPerformance Metrics - II
In this section, we mainly look at benchmark modes in programs used on a day-to-day basis, i.e, application performance and not synthetic workloads.
x264 Benchmark
First off, we have some video encoding benchmarks courtesy of x264 HD Benchmark v5.0. This is simply a test of CPU performance. Here, we find the second pass results track the theoretical capabilities. The first pass, however, puts the Bay Trail Celeron N2808, the Braswell Celeron N3000 and N3050 approximately in the same ballpark (between 9.75 and 10fps).
7-Zip
7-Zip is a very effective and efficient compression program, often beating out OpenCL accelerated commercial programs in benchmarks even while using just the CPU power. 7-Zip has a benchmarking program that provides tons of details regarding the underlying CPU's efficiency. In this subsection, we are interested in the compression and decompression MIPS ratings when utilizing all the available threads.
TrueCrypt
As businesses (and even home consumers) become more security conscious, the importance of encryption can't be overstated. CPUs supporting the AES-NI instruction for accelerating the encryption and decryption processes have, till now, been the higher end SKUs. However, with Bay Trail, even the lowly Atom series has gained support for AES-NI. The Celeron N3050 in the LIVA x2 does have AES-NI support. TrueCrypt, a popular open-source disk encryption program can take advantage of the AES-NI capabilities. Even though TrueCrypt is no longer under development, its internal benchmark provides some interesting cryptography-related numbers to ponder. In the graph below, we can get an idea of how fast a TrueCrypt volume would behave in the ECS LIVA x2 and how it would compare with other select PCs. This is a purely CPU feature / clock speed based test.
Agisoft Photoscan
Agisoft PhotoScan is a commercial program that converts 2D images into 3D point maps, meshes and textures. The program designers sent us a command line version in order to evaluate the efficiency of various systems that go under our review scanner. The command line version has two benchmark modes, one using the CPU and the other using both the CPU and GPU (via OpenCL). The benchmark takes around 50 photographs and does four stages of computation:
- Stage 1: Align Photographs
- Stage 2: Build Point Cloud (capable of OpenCL acceleration)
- Stage 3: Build Mesh
- Stage 4: Build Textures
We record the time taken for each stage. Since various elements of the software are single threaded, others multithreaded, and some use GPUs, it is interesting to record the effects of CPU generations, speeds, number of cores, DRAM parameters and the GPU using this software.
Dolphin Emulator
Wrapping up our application benchmark numbers is the Dolphin Emulator benchmark mode results. This is again a test of the CPU capabilities, and the ECS LIVA x2 is matched closely only by the LIVA X. As expected from the clock speeds, the LIVA x2 performs better than the Beebox.

Hi BMN! Not everyone out there is concerned with video playback for a system like this. As a small/cheap/quiet word processor and e-mail fetcher, platforms like the Liva x2 are perfectly suitable. Also, many people don't really worry much over specific decoding capabilities. As long as their new little computer can stream YouTube, Netflix, and Hulu, there's nothing to worry about and digging into the specifics isn't important or relevant.kmmatney - Monday, August 24, 2015 - link
I have a baytrail 3735D (quad core), which benchmarks about the same as the Braswell N3050, and while it seems fast enough most of the time, there are way to many instances where it skips and lags. Maybe it has to do with the eMMC storage, the overall experience isn't great. It's fine for a little while, but open up a few web pages, and things suddenly slow way down (with 2GB of RAM).BillyONeal - Monday, August 24, 2015 - link
Perhaps you meant envelope ?

I just built a ASROCK N3150 B based HTPC and am quite impressed with the performance. The quad core chip comes for the same price as the N3050 and is quite impressive at I think it was like 6 watts of power. First time using a fanless CPU it feels awesome and weird when you turn on the system. You don't really feel its turned on! Perfect for watching all kinds of movies!BMNify - Monday, August 24, 2015 - link
you are far better off buying any Amlogic S812 or related HTPC box with http://www.cnx-software.com/ that comes with HDMI2 at 60fps HW/SW playback NEON 128-bit SIMD (and encode if its activated) as a generic option than even the very latest Atom x5 x5-Z8300 that yet again removes AVX/2 SIMD and is by all accounts not even as good as the antiquated Atom-Z3735F Q1'14 http://cpuboss.com/cpus/Intel-Atom-x5-x5-Z8300-vs-..."Instruction set extensions

BMNify, I'm not aware of any Amlogic S812 box with HDMI 2.0, can you give an example? CPU wise, Braswell is more powerful than Amlogic S812, for example a N3150 can decode H264 Hi10p. It's a pitty that Anandtech doesn't test the Braswell boxes with the latest OpenELEC beta versions...BMNify - Monday, August 24, 2015 - link
see http://kodi.wiki/view/Android_hardware for list to start with several Rockchip ,Amlogic, and x1 devices are capable, you need to review them and choose your requirementssearch "Amlogic HDMI 2" etc and try here for a device that suits you http://www.geekbuying.com/Search/?keyword=RK3288

I have the original LIVA, which has a N2807, and costs about the same as this new one. I love it!The only reason to "upgrade" would be for the better GPU and slightly better wifi. The CPUs, in fact, are equal in ability: http://www.cpubenchmark.net/compare.php?cmp[]=2263&cmp[]=2541
But actually, the X2 seems like a worse machine. It's bigger and sips more power. If you're interested in this box, consider getting the original model if you can find it!

For so many years Anandtech's HTPC reviews have been spreading misconceptions about the 23.976Hz refresh rate. As an avid reader, I used to think getting the perfect 23.976Hz refresh rate is all you need and have spent countless hours trying to do that with the various HTPCs I've owned over the years.As you used madVR to test HTPC "credentials", it unfortunately lacks an important metric in its debug OSD -- the actual frame rate the video is being played back. This takes the reference clock into account - so even if the display refresh rate says 23.976Hz (which in this case isn't even close - it's only 23.974Hz), you still have to multiply that by refclk (-ve makes it even lower). As you could see in your own screenshot, you still get a frame drop every half an hour. The unfortunate thing about this is, every ECS LIVA x2 box is going to have a slightly different rate.
And let's not forget that not all sources are 23.976fps - some are true 24p video, others are 60p etc. Some monitors still don't report 60Hz in its EDID!
To get true frame drop-/repeat-free playback, your media player needs to have the ability to do something like Reclock. Most of you probably haven't noticed but the DirectSound Audio Renderer (or any non-exclusive audio renderers) already resamples your audio before it goes out to your audio card (the only case where it doesn't resample is when your audio stream is the exact match of your Windows global audio settings and nothing else is playing audio). As such, asking the audio renderer to resample the audio a bit to make it match the display refresh rates won't affect the audio quality much but it will get rid of frame repeats / drops completely. If you care about audio quality, the Sanear Audio Renderer in Wasapi mode is the preferred choice. Anything less than 3% in clock adjustments will yield max audio quality. So even if you have a 24Hz refresh rate, adjusting 23.976fps to play at 24fps won't affect audio quality.
MPDN has an open source implementation of Reclock (to be used with either DirectSound or Sanear Audio Renderer) - https://github.com/zachsaw/MPDN_Extensions/blob/ma...

Why not run the thermal test with the top of the unit off?
