Viliv X70 EX UMPC Full Review with Videos

Updated on 10 June 2018 by


We’ve tested the Menlow platform extensively on 4 different PCs now and we’re extremely happy with it’s balance of performance and efficiency for mobile usage. We pages load promptly and media playback works well. As a synthetic test, we ran CrystalMark:

CrystalMark test results

CPU, GPU and Memory scores are all on par with other 1.3Ghz devices we’ve tested but you can see the exceptional SSD speed results in the second set of results. (right hand side.) The lowest line of results, a 4KB read and write test, is important. The 1.192 figure is slightly lower than expected but certainly not critically bad.


Video performance.

The Viliv X70 includes the Intel US15W chipset which uses the GMA500 GPU and video decoding hardware for H.264, WMV, MPEG4 and MPEG2. Out of the box, Windows XP isn’t set up to use this hardware so video decoding results with Windows Media Player aren’t as good as they could be. Viliv have worked round this problem and enhanced the video playback performance by including a video playback application called Viliv Player. It’s a simple video player but a useful one as it enables some high performance playback using the build in hardware decoding. Not only does this improve the performance, it saves battery life by keeping the CPU usage down.  Results were the same as we’ve tested on the Viliv S5. For example, when playing a 4mbps 720×400 DivX, the CPU level was at about 30%. A 1280×720 H.264 file (at 3.5Mbps with AC3 audio and subtitles in a Matroska envelope) played perfectly with just 25% CPU utilisation. There appears to be some acceleration of WMV files too but this doesn’t seem to be as good. A 6.5Mbps file we played started stuttering after about 20 seconds. In general though, the media player performance is very good and the colours, sharpness and contrast are exceptional and the experience on the 7 inch screen is one of the best we’ve seen.

[Note: Video playback results will vary with different files, filters, drivers and playback software]

As for inline flash video, the normal quality YouTube videos work well in both windowed and fullscreen modes. HQ videos are smooth in windowed mode but we’re seeing better results than on the S5 in full screen HQ mode. Certainly this XBox promo video plays smoothly and impressively. The 1.3Ghz CPU is not powerful enough to show HD quality YouTube videos despite these being in H.264. The flash player does not link with the Intel hardware to enable hardware decoding. [Tip: YouTube HD videos can be downloaded with the help of 3rd party software and then played offline from the disk outside the flash environment. ]


Audio quality from the Viliv X70 is excellent in comparison to other UMPCs. The speakers are loud and clear. Better than the S5 although some background hiss was present. The audio output is very clean though and easily usable as a HiFi source. The Bluetooth stack is capable of A2DP too so there are good options for listening to audio tracks.

Web Camera Performance

The WebCam is reasonable quality and is driven by the Cyberlink YouCam software (which provides a virtual webcam interface to other software and allows the user to insert overlays and effects and includes recording and snapshot capabilities) and works extremely well with Skype. In a test between the X70 and the Gigabyte Touchnote that I have, the quality, framerate and colour was very good. The Cyberlink live effects are fun to play with too. The offset webcam position is the only issue to note.

Heat and noise.

Viliv have designed the X70 without fan which results in silent operation. There is some warmth after prolonged use and the metal mount point can get very hot indeed. We’re surprised that the bigger form factor appears to generate more heat than the Viliv S5 under load. We would not recommend leaving this device in the case, in a bag while under any medium to high load. If you are going to leave it on in a bag or case, ensure that the screen is off and that the device is set to power-save mode.


We have seen two instances where the X70 has failed to go into standby. This might be related to 3G activity but we can not be sure. A forced power-off resulted in a (successful) disk check on reboot. In normal usage we haven’t seen any crashes or ‘blue screens.’

Boot-up, standby, hibernate speeds

Boot-up from cold is very quick at about 30 seconds from power-on to being able to use the Windows XP start menu. Standby (return) takes about 5 seconds. Viliv claim a standby time of 150hrs. We have not tested this.

Due to the small disk size, fast cold boot and long standby times, we recommend that hibernation is turned off to save disk space.

Battery life.

As with the S5, Viliv don’t seem to have completely implemented battery information status into XP. All you get is a battery % indicator without the estimated remaining battery time. Users are used to seeing estimated battery life on XP so this is a noticeable shortfall on the X70. [Update: We are in contact with Viliv on this issue and it may be resolved in the final build. We will update this report when we get info.]

We tested the X70 EX with Battery Eater and the X70 was able to run this test, a full-load GPU, CPU and disk test with Wifi on and a screen brightness of 50% for 5 hours.  Based on this we expect the X70 EX to return around 6 hours of Wifi-on browsing, over 10 hours of MP3 playback and about 5-6 hours of video playback. The X70 EX is the most energy efficient 7 inch PC we’ve ever tested.


A SirfStarIII GPS chipset is included and as with the S5, we had some initial problems getting it to work. A ‘GPSSwitch’ application is included and this is supposed to toggle the baud rate of the COM2 port between 4800 and 9600 helping programs to attach to the GPS but the program failed with an error and our simple iPoki client couldn’t get any figures from the GPS. Once we had downloaded VisualGPS (recommended for testing GPS on windows) and monitored the port (COM 2 at 9600bps) until it had a lock, the ipoki client worked. Once a lock was established, the unit was able to retain a signal in the middle of a house on the first floor which is a good result.

Application tests.

  • Firefox3, Tweetdeck and Twhirl all tested perfectly as expected.
  • Skype V4.0.0.224 works well. Built in mic and camera are good. No echo issues. Sound quality good.
  • YouTube – works well All normal quality YouTube videos tested well in windowed and full-screen mode. All HQ videos tested worked in windowed mode. Many worked perfectly in full-screen mode too.
  • ITunes works smoothly. Including 3D cover flow effects.
  • Other software tested: Ipoki plugin with built-in GPS.

In general we don’t expect any software compatibility issues. The CPU and GPU define the limits of this device. We don’t recommend it for heavy 3D work. (Gaming)

Firefox load times.

  • Firefox application startup time: 3.5 seconds

Page load examples (full script and flash support over Wifi.)

  • UMPCPortal: 10 seconds
  • Google News: 2 seconds
  • 7 seconds
  • Facebook 3 seconds to login screen
  • 3 seconds
  • Techmeme: 6 seconds
  • Gmail (full version): 7 seconds
  • Google Reader (1000+ items): 4 seconds

Overall, page loading times were extremely fast and in some cases, matched desktop speeds indicating that the X70 EX is capable of processing web data as fast as web servers can serve it.


We haven’t tested any games with the X70 and due to the relatively poor 3D performance figures, wouldn’t recommend this for modern gaming.

WiFi/Bluetooth quality.

Bluetooth quality was not extensively tested. The system uses BlueSoleil version 5.4.256 which, in our opinion based on a number of devices running the same stack, is stable and easy to use.

We had no problems at all with Wifi configuration or reception. Reception appears to be slightly better than average for UMPCs. The Marvell sd8686 only supports B and G modes.

3G Quality

The HSPA modem provides support for the latest UMTS standards and we were able to get good results from a local cell with downloads of 1.5mbps and uploads to 800kbps (proving that it supports high-speed upload.) However, reception drops off fairly rapidly. In an underground cellar test, the X70 EX was unable to get any signal.  Only a few devices that we’ve tested have passed this test though so it’s an extreme case. In normal use, the reception seemed perfectly acceptable.

According to Viliv, the extendable antenna helps with edge-of-cell use but we were unable to detect any change in reception quality of transfer speeds.

The pre-installed software, ‘Mobile Partner’ v 11.3 from Huawei is good and provides a nice set of usage statistics. SMS’s can be sent and received easily through this interface too.

USB transfer capability.

The mini-usb portcan be used for direct transfer of data to another Windows-based (or Apple-based, we understand) PC as it contains built in USB transfer hardware and memory that contains transfer software. The feature is the same as you get with USB transfer cables and provides a very fast way to transfer data. The video below demonstrates this feature.

    Thank you for the great review! Hopefully the screen protector will be available during launch. I was planning on getting ClearTouch glare reduction film for it. I may still if glare reduction is not available.

  5. tmarks11 says:


    How about a snapshot stacked up with whatever otehr UMPC/MIDs you have lying around so we can get an idea of relative size?

  6. Velik says:

    look at jkontheruns comparison of S5 and X70. It shows this very nicely, and i can tell you im drooling over the x70, assuming it can perform ok with the applications i need to run on it.

  7. Lion77 says:


    “It’s tough to move and has a smooth surface making it even more difficult. We hope that this is the last 2% that needs to be fixed on the X70”

    I hope that viliv would fix for us. :)

  8. Vit says:

    I am looking forward to owning this device. Although I have two questions:
    – Is it upgradable to Windows 7, I mean drivers etc..
    – Does the screen is capable of supporting handwriting recognition?

  9. ZC says:

    Since the X70 has similar hardware to the S5 see this:

  10. Velik says:

    he may have had a hard time installing windows 7, but thats fairly difficult to do when you dont have a dvdrom anyway. Sometimes installing from a sd card or usb drive can be tricky but i’ll be happy to post about my experience. However, x70 is more than capable of running windows 7.

    as far as handwriting reco, I should be able to recognize to some degree. I’ll use the windows 7 ‘tablet pc input panel’ and see how well that works out.

    How’s viewing images?

    Can you load up some 6+MP digital images, view them to fit full screen using ACDSee/etc, and page through them. Any delays? Slow image-to-image? Fast?

    Think it’ll be a wonderful, portable image viewer for photo shoots, but need to know if it’ll keep up.

    Great review.
    Wonder what happened to the 4.8″ device with keyboard?

    any news on what linux it will run and if it’ll be available form anywhere with linux? It’s also amusing that the dynamism site says pre-order but you can’t click a link to pre-order it!

  19. steve says:

    I know I might get burned for this, but I have to say it:
    Is it just me or do the prices for the Viliv X70 upgrades seem rather expensive?
    $599 for the basic model is fine, but $130 extra for a very slightly better Atom and the 32GM SSD (I would have thought somewhere around $100)
    Ok, let’s say that is worth it, but then another $150 for the Huawei 3G unit. That seems costly to me when compared with other units which have the same options available with the Huawei. (I would have thought somewhere around $100)
    I was anticipating the top unit to be priced about $750 – $780 tops.
    Am I being cheap?

  20. ZC says:

    I checked around and those embedded radios are at least $150 alone. For instance:

  21. ZC says:

    About $115 for a 32GB 1.8″ SSD (assuming it uses the same 1.8″ slot as the S5)

  22. Steve says:

    Thanks for your thoughts. I guess I was about right, then.
    The links you provide give the prices that you and I can buy them for. I’m sure Viliv can get them for at least half that price, if not a great deal more.
    Although the convenience of having an inboard 3G would be great, I’m no longer sure I want to pay over $879 (+ tax – and possibly + S&H) for the X70.
    I think I might go for the base model with the chance of upgrading later if required.
    Is there really that much difference in the 1.2 Atom and the 1.3?

  23. Lion77 says:

    If you see the video from http://WWW.umpcfever and JKK mobile. Even S5 use the small form factor of SSD not 1.8inch SSD.

    I am wondering how about X70EX. Is it same? :)

  24. Vincent says:

    Great full review! I am wondering for battery life on X70 EX.

  25. chippy says:

    5-7 hours in productive use.


  26. hnzw_rui says:

    Very nice review. Same as others, I think it would be great if you can look at the innards and see the size and connection of the SSD they use. It would be really useful for those who wish to roll their own upgrades.

  27. ambivalent says:

    Will these devices run Office 2007? I want to run OneNote 2007, Personal Brain and/or MindManager, *and* Word, Excel and PPT on a small tablet. Aside from user interface issues (I’ll deal with that), will the processor and SSD on the S5 or X70 support normal use (aka, NOT SLUGGISH) office apps? /pg.

  28. stellar says:

    Chippy. Could you remove the red color on post? It is very annoying me. :(

    btw, it looks very interesting device for me.

  29. chippy says:

    Red color?

  30. RedSunset says:

    Chippy – I’m new to this forum and might be wrong but I guess you and the guy that posted the full review video of the X70 on Ustream are one and the same person.

    I thought your review was generally thorough and professional. I was quite impressed in fact. That was except for the sudden, and to a degree unwarranted, ‘Apple-bashing’ moment, which quite honestly just showed you up and acted as a moment of hilarity in the video… not least because it was quickly followed by you adequately demonstrating how 3rd party Microsoft software (in this case YouCam) can have the very same hissy-fits that you seem to completely lose the rag with iTunes over.

    I have a foot in both camps and am as comfortable in XP, Vista or OSX. Microsoft and Apple both have the merits and their downfalls in equal proportions. If you’re to be taken seriously as a reviewer of such gadgetry, I think you should try to show a little more impartiality in your work.

    As for the X70 though… what a cracking bit of kit! I can’t wait to add it to my every growing collection!

  31. Chippy says:

    Hi. Yes, that was one and the same Chippy.

    Thanks for your feedback. Itunes has proven, time and time again, to be a pain in the arse on UMPCs so I rarely give it much time now. Sorry about that. It’s just experience that tells me to move on when itunes doesnt work. Cyberlink YouCam is something new to me so i’m trying to learn about it. Hence the extra time I gave it.

    Hope you understand.

    Regards and thanks again for feedback. Looking forward to your thoughts about the X70.


  32. RedSunset says:

    Thanks for taking the time to reply and especially as my comments were not too glowing. That in itself is a credit to you. Bravo.

    I agree that iTunes is not great ‘out of the box’ (be that within OSX or Windows) on the UMPC form factor but, equally, neither is FireFox until you’ve tweaked the settings in about:config and the icon size, installed Grab and Drag and X-marks and generally optimised the browser for Google Reader. When you take the time to tailor FireFox to the tablet/umpc/touchscreen criteria it is by far and away the best browser option and I would honestly say that, tweaked, iTunes is the same as a vehicle for is mp3s, 4s et al. As a broadcaster you (and JKK for that matter – who appeared to think a lot of the 3rd party software on the X70 was, and I quote, ‘stupid’ LOL) have a certain responsibility because a lot of your viewers and followers will respect your words and take what you say as read, without thinking to investigate further for themselves. You need to demonstrate impartiality at all times to provide constructive and insightful feedback on the new it you’re privileged to have access to – gizz-a-job! ;O). One successful broadcaster that does this perfectly is Mr Kendrick of JK-on-the-run fame.

    A lot of what Microsoft and their 3rd party support does is wonderful, once tweaked, and the same can be said of what comes out of California and Apple.

    One immediate thought on the X70. The guys at Viliv are probably scratching their heads on the extended battery issue as to introduce any kind of alternative (6 cell or other) could well, through size, impact on usability of the car mount. That aside and without prejudice, yours did seem a little temperamental. Video playback wasn’t as smooth as I would have hoped (there appeared to be a couple of playback ‘judders’ that you didn’t seem to pick up on even in standard playback) and the whole thing with YouCam did seem to suggest it can (as most of these things can) have a mind of its own at times. None of this would stop me buying the X70 though, it’s amazing how figuring you can be of something when it has great sex appeal!

    Who in the UK is likely to distribute, Expansys?

  33. RedSunset says:

    * it’s amazing how forgiving you can be of something when it has great sex appeal!

  34. Chippy says:

    For me its about being truthful (one of the great advantages of the live session is that we can’t lie!) and balancing that with some personal character. Im not a trained journalist but so far this recipe seems to be working really well for me, the readers and the people that are kind enough to send us their products for review.
    Again,thanks for the feedback. It all helps with working out where the balance point should be.

    What FF optimisations do you use then? I load grab and drag and thats it.


  35. Chippy says:

    Regarding uk distribution, I dont know. Mobilx are looking at it but thats all i kmow.

  36. Vakeros says:

    Dynamism have it on their UK website for preorder.

  37. UMPCwatch says:

    Hi there!
    As I am about to join the race for the Viliv X70 EX pre-order, it is not surprising that I have started to question some of Viliv’s features.
    Most notably, these are two such things:
    – The on-screen keyboard
    – The 3G modem

    I have not been able to answer the following simple question: how would the on-screen keyboard behave with two languages? Being a bi-lingual person, I am VERY keen to be able to switch between the two character sets without using an external keyboard. Is this possible at all???

    On the second (3G modem) issue, where is the SIM card slot? I might have missed a pertinent discussion, though – so then forgive me for this second question … but there is more to that, besides a mere interest to the SIM slot location. Is that possible to use Viliv 3G with the SIM card inside as a regular mobile phone? I do not ask for concurrent data and voice streaming, a simple switch from one to another would suffice!

    can someone address my questions?
    TIA as always!

    P.S. and many thanks for the review!!!!

  38. Chippy says:

    I’m getting some news that the retail version may include a voice-capable modem. Stay tuned for more information.


  39. UMPCwatch says:

    Thank you, Chippy! That would be great to have the full-blown support – the both voice and data over 3G.
    How about the first question? I am wondering would the on-screen keyboard switch between the two language sets?
    As usually, thanks for the great job!

  40. newcgeoman says:

    where can I get an on screen keyboard like this for my t1028?? I’m trying comfort keyboard at the moment, but the one on the x70 looks way better!

  41. designer says:

    I really like the reviews and have a question ind regards to the versions;
    what is the difference between X70/32ssd/Premium-3G and X70/128ssd/Premium-3G?
    Is it the harddisk size only? Would I be able to upgrade to Windows 7 with the 32ssd version or the 128 will perform much better.


  42. Jonathan says:

    I noticed you tested MKV playback: “1280×720 H.264 file (at 3.5Mbps with AC3 audio and subtitles in a Matroska envelope) played perfectly with just 25% CPU utilisation.”

    Have you tried any other H264 encodes – such as those with AC3 or OGG audio, and do they play as well?

  43. Angel says:

    DELAY delivery from Dynamism. I just talk to the phone and speaked with Jeff, he told me there is a delay, they did not received Viliv X70. Wish…soon!

  44. Transilvan says:

    That is a catastrophy! Why did they not write this some days earlier. The charged the money 3 weeks ago and dont deliver!!!

  45. Angel says:

    Sure, they make a lot of interest with all the lot! Also, they tell nothing yesterday when i called, they told at Dynamism it must be there tomorrow. I received an email telling, “maybe! In 2 weeks (not sure!). Why companies announce new products 2 years ago, they already have working demos, and even after telling will be there a date, the SAME day supposed to be here, they won’t have, for MAYBE weeks more! ebay don’t permit, to get payment without having in stock!

  46. Norman D. Robinson says:

    Hi…, will there be a version that has 2GB of RAM and “Windows 7″…??? I would really like to make this my desktop replacement. Also, I think the “CarKit” could be used as a stand on a desk. Basically like a passive docking station of sorts. I think when I order mine I will get two stands. One for the car and one for my desk in the office.

    But apart from that, what are the development plans for the “X70 EX”. Will there be a 2GB RAM version…??? Thanks for answering me folks. ;-)

  47. Angel says:

    My Viliv X70 works only at 4800 bauds NOT 9600 bauds! It’s very fast and acurate. If i switch to 9600 it DOES NOT WORK!
    I just switched at 4800 works fast and fine. when i return at 9600 does not work at all, i have the new Viliv X70. Maybe they had shortage of 9600 modules. Does will be less acurate or slower at 4800? What is the difference? Thanks a lot for your great helps. Now, the sky is the limit!

  48. Steve 'Chippy' Paine says:

    @promethh Let me know if you have any questions. I have two Viliv X70’s here! Review: #umpc

  49. Steve 'Chippy' Paine says:

    @artr Yep. Origami with dialkeys. See the latest viliv X70. I’m on the sofa with it right now.

  50. Larry Heyl says:

    I’ve been looking into eReaders for a lengthy trip to Asia in a few weeks, and had settled on the new Sony eReader, but this, even at twice the price, is very interesting. Some specific questions: does the unit charge at all when the transfer USB is connected? How much of the SSD is used up by Windows, etc.? (in other words, how much of the 16 Gb is left over?). Also, how hard is it to switch from landscape to portrait mode?

  51. Jonathan says:

    The unit doesn’t charge in SSD mode. As shipped a large portion of the ssd is the recovery partition. I backed mine up using Acronis True Image and wiped the recovery partition and turned it into a D: drive which I use for storing media. Fortunately, that partition was the second partition, so there are no boot concerns. Switching screen modes is simple – press the “C” button (on the bottom right of the unit) along with a direction of the directional stick and it rotates.

  52. Larry Heyl says:

    Thanks for the info. How big was the D: partition? Still thinking about what I want to do. I have to decide in the next day or two.

  53. Jonathan says:

    I don’t have it in front of me, but I think it was about 4.5 Gb on that partition. There was as much free on the C: with windows installed.

  54. Jonathan says:

    As a followup to my post about MP4 playback – I have not had much luck with the built in player, but using KMPlayer and turning off internal codecs for H264 and AVC video and using the “ffdshow” option for external decoders allows me to watch 720p MKV files and also MP4 files I’ve ripped from my DVD’s at around 2000 Kbps flawlessly. Non H264 based media (such as higher quality FLV files) are a little choppy still, though – doesn’t seem to have any internal support.

  55. Mike says:

    Any idea if the X70 will support palm rejection? It is neccessary as I will be using whatever device I choose for note taking functions?
