The more I test Intel Sandy-Bridge based systems the more I am becoming convinced that laptop silicon will eventually extend as a high-dynamic-range platform into to ultra-mobile PCs and tablets. The reason is that the new laptop platforms are using advanced processes and techniques and are extremely efficient at getting things done. ‘Hurry Up Get Idle’ is a simple concept that means if you can get the same job done quickly, you can turn off or idle a pc and thus reduce the power used. The area under the power curve is smaller.
In practice, its difficult to make HUGI work because a lot of the tasks we do are either very short, can only work as fast as a human can input or rely on data coming from other sources. PC’s aren’t very good at idling either but from my recent video editing tests, I can see that there’s at least one scenario where it works very well.
The problem with getting laptop silicon into a handheld product is the thermals. Intel leads the way in this market and their products provide plenty of thermal monitoring and control but it will take a little bit more than what is currently on offer to be able to easily design and produce a 7″, tablet running a laptop-style processor. It’s been done before though. Samsung, experts in electrical engineering, produced a 7″ Tablet running a 1.3Ghz Core Solo but that was at a time when there was no competition from ARM-based devices, $1200 tablets were common and there wasn’t an Atom processor around. The latest tablet example would be the Eee Slate EP121 and for a 1.06KG laptop, the Samsung 900X1A gets close but that’s a little larger and heavier than a handheld device should be.
As silicon processes get better though and thermal control, dedicated silicon and single-chip solutions become more common, you can expect both Intel and AMD to try to offer the ultimate processing power in the handheld space. You can expect these products to have premium prices and to be targeted at niche markets but with Windows 8 as a catalyst and competition increasing from the latest ARM designs, offering these niche product is one way that the X86 chip makers can retain an advantage and one way manufacturers can differentiate their products.
Just over a month ago AMD announced their tablet-focused Z-01 APU, a dual-core APU focused at the Windows Tablet market. On-stage at the announcement was MSI showing off the Windpad 110W. We’ve seen a video and had a taster of the specs and hints about the price but today we’re able to bring you something more official.
Remember the MSI Windpad 110W has the 1280×800 screen and integrated mouse pointer, 32GB SSD, HD decoder (via the 6250M graphics,) 2GB of RAM and Windows 7 Home Premium A well balanced feature set for a mobile PC. With a 2-cell battery we’re probably looking at 30-40Wh of power (unconfirmed) which is a 3-5hr usage time. If the Windpad includes some nice accessories (we’re assuming the docking port is still included) it could make quite a well balanced product. And good value too.
We’re seeing a 32GB non-3G model for €559 (Notebook.de) and a 3G model for €659 (also Notebook.de) The only thing missing is availability, and of course, a full test.
Netbooknews are seeing 2GB of RAM (the platform support 4GB in theory) a 4200mah battery (probably 30wh in total) and a 32GB SSD.
Let’s remember that while the GPU is a real bonus and advantage over that which is delivered in the Intel Atom platforms, the CPU comes in between an Atom N450 and an N550, assuming it’s the same core design as an AMD C-50. A lot of the responsiveness is going to hinge on the performance of the SSD. The battery life is going to hinge on MSI’s engineering skill because a 5.9W TDP doesn’t allow room for sloppy electronic design.
I like the integrated mouse pointer and the docking station port. The 3MP camera (not 5 as mentioned in the video, we believe) could be useful too as that’s rare on a Windows device.
Price-wise we’re looking at around $599 if the pre-order rumours are true.
The Z-01 APU was announced yesterday in a blog and press release but AMD have just demonstrated it on stage at Computex. It looks like they’ve re-named the low-power C-50 part they’ve already talked about, a variant of which I believe is already in the Acer Iconia W500 Tablet so don’t get too excited as we’re talking about a 5.9W TDP here, not an ARM-architecture competitor just yet. It lines up nicely besides Oaktrail as a platform that can enable a good Windows tablet experience.
Interestingly, AMD accepted that Windows tablets haven’t had a huge amount of success recently and tipped a hat to Android by demonstrating a runtime version of Android which is provided by Bluestacks. We’ve already seen this briefly on the Viewpad 10 Pro.

Announced features of the Z-01 are:
AMD Z-01 APU with AMD Radeonâ„¢ HD 6250 discrete-class graphics. This APU features two 1 GHz “Bobcat inch CPU cores and checks in at TDP of 5.9 watts.
Full intelligence and operability of the Windows® 7 OS
Consistency in user interface and applications from work to home
Full access to view and edit work and personal documents created in Microsoft Office and other leading applications
Free and automatic online Windows 7 OS updates to enable the most current features
Full compatibility with iPhone, Windows Phone, Blackberry and other leading mobile phones
Seamless connectivity with virtually any USB device
HDMI support to enable a full 1080p visual experience
Full compatibility with XBOX 360 Media Extender Functionality
The first product to officially use the Z-01 will be the MSI Windpad 110W which has previously been reported as having a C-50 APU. We’re not sure if it’s going to ship with the Bluestacks Android layer.
In a press release, MSI state that the Windpad 110W will have six-plus hours of battery time “the longest of any tablet with Windows architecture. inch which is actually BS because I’ve got two here in the studio that will beat that. They’re based on last-gen Intel platforms too!
AMD do a great job with Fusion and the marketing is as smooth as silk so we’re reserving judgment until we get that 110W in our hands. As for Bluestacks it looks like Myriad have a competitor which is great news for us consumers!
You may recall that I lost a number of days work last week. Test results, screen caps and a whole bunch of text went out the window when I did a factory re-install on the device I was both testing and writing the article on. That will teach me!
The article was Part 4 of the Ultra Mobile Video Editing series and was a detailed look at two Brazos-optimised video editing applications on the Lenovo S205 AMD E-350 device. The results were, in general, quite impressive with both Cyberlink Power Director 9 and Corel VideStudio X4 showing use of the platforms features. In some cases, hardware video decoding and effects rendering was significantly speeded up through use of AMD Brazos features. In some cases, the results weren’t so good. It all depended on the type of output file.
After I lost my work on the reivew I wrote an overview of AMD APP enhancements amd i’ve just updated that with input from AMD and Cyberlink. The key thing to know with the C and E-Series APUs is this AMDs video encoding acceleration subsystem (which used to be called Avivo) which is used by many of the AMD enhanced video editors and converters, is not implemented on the E-350 (or its drivers.) It’s likely to be because it’s actually slower than the CPU but the end result is that there are limits to the enhancements that can be made.You can’t expect General Purpose GPU (GP-GPU) enhancements.
The diagram above shows the Cyberlink PowerDirector Brazos acceleration process. Note that the encode stage is 100% CPU bound. Actually this Cyberlink diagram is slightly wrong because there are some encode enhancements implemented in specific effects code that has been written to use Open CL/APP by Cyberlink.

Ultra Mobile Video Editing Test Results.
The parameters I’ve set for the project are shown below and you can read about why these parameters have been set here.
PC and software to cost less than 600 Euros
PC to be less than 1.5KG with 12 inch screen or less.
Total camera + PC solution to weigh less than 2KG and cost less than 1000 Euro
Source video should be 720p
Video sent to YouTube should be 480p minimum
Editing solution must include watermarking, overlays, crossfades, and multiple audio tracks.
Testing results. (Summarised from paper notes taken during testing.)
Source file: H.264 720p 8mbps 25fps. Output file H.264 720p 5mbps. All possible acceleration turned on. System power settings set to ‘always on’ (full power.)
1 Corel VideoStudio X4 managed to do this test in 3.7x real time which, for such a heavy processing job, is impressive. PowerDirector 9 took significantly longer.
2 In this test, the video decoding accelerations and memory transfer accelerations implemented tend to have little effect as the processing is very CPU intensive. Hardware video decoding and memory optimisations start to have a more significant effect where output files are smaller and use a less complex codec. 720p H.264 input and MPEG-2 DVD file output is a good example. Resutls were the same with and without accelerations enabled. Using the AMD System Monitor (V0.91) very little GPU activity was seen.
3 Using Corel VideoStudio, the E-350 CPU was 1.5x faster than the C-50 and 2X faster than an N450 CPU on this specific video encoding test.
4 For this project (480p minimum output size requirement) there wasn’t an output profile on either software suite that supported the required 852×480 output resolution. 852×480 is a favorable resolution for enabling HQ/480p experience on YouTube.
5 By adding DivX Pro to the Lenovo S205 I was able to create the required output in an AVI container. I was not successful in getting MP3 audio into the container but I’m confident this is possible. Divx Pro is a 19 Euro license. Divx Pro is a similar implementation of MPEG4 to H.264 (MPEG 4 Part 10) The rendering speed was approx 2.2X real time. This was the best result I achieved in all the tests I did and one that proves the AMD E-350 is capable of producing fast results for my specific video editing and upload requirements. Based on this test it appears that Divx Pro is more tunable (for both resolutions and encoding speed) than the H.264 codecs used in these editing suites.
6 I was able to output a 720×576 file with 16:9 aspect ratio (correct when re=sized to 852×480) using Power Director 9. The rendering speed was an impressive 1.8x real time. This option as sub-optimal as some resolution is lost when the rendered file is squashed into a 720-wide frame.
Other notes:
The YouTube processes on both Cyberlink PowerDirector 9 and Corel Videostudio X4 don’t support an HQ profile. On Cyberlink, the profiles outpur WMV files which took much longer then H.264 files to output. (Aprox 5.5x real time)
VideoStudio took a very long time to start from fresh boot. Over 60 seconds. PowerDirector 9 is about 25 seconds to start up in the same scenario.
Both video editing suites were fluid in their editing processes.
Power Director has some effects that are implemented in OpenCL for a significant acceleration advantage.
NotebookItalia also did tests (translation) with Corel VideoStudio and got similar results with Corel VideoStudio . We worked together on cross-checking our articles before posting.
Summary
Editing 720p content with these two software packages is quite acceptable for small, in-field projects. Rendering profiles need to be chosen carefully though to get the best out of the system. For my requirements a 720p H.264 file input and a 480p file output for optimal YouTube uploading I found that a combination of Corel VideoStudio and Divx Pro worked best. Hardware and memory acceleration works in this process and with an 8mbps H.264 720p file input and 480p 30fps file output with ‘fastest’ Divx encoding settings and a 2Mbps bitrate. Rendering rate was 2-2.5x real time depending on audio codex setup. (Using high-power ‘always on’ battery settings on the system.) The images below show most of the configuration settings used.
With most of the process being CPU-load though, one wonders what a dual-core N570 CPU would achieve with the same test. I will be looking to get that result added to this report as soon as possible.
Let us all know about your mobile video editing experiences in the comments/discussion below.
Stay tuned for the next part of this series where I will be testing a standard laptop CPU and chipset, possibly an Intel Sandy Bridge system.
I’ve been working on a big ultra-mobile video editing article since last Wednesday that gives you all you need to know about video editing on the Lenovo S205. Unfortunately, I just re-installed the S205 OS and forgot to backup the directory where the draft article was. I’m hoping to recover the file this afternoon but I can at least tell you one thing The Lenovo S205 (and possibly Acer 522) don’t support the important AMD Video Converter (Avivo) software from AMD because they have special driver builds that do not include this layer. The Avivo software, as far as I understand, is the base software on which video encoding software (as in video converters and video editing software) that are AMD APP-enabled, hook into to get a GPU hardware boost from the E-350 APU for rendering H.264 and MPEG-2.
Update:07 April 2011
I have had a conversaion with an engineer from Cyberlink who confirms that AVIVO-based encoding acceleration is not supported on these [E-Series, We suspect C-series too] AMD Fusion devices. In fact, what’s really happening here is something more important. AMD Fusion [E-series, C-series] does not support video encoding acceleration. The APP (was ATI Stream) feature that is used by the AMD Video converter base software (was AVIVO) is not implemented. Information from Cyberlink…
Fusion APU does not support Accelerated Parallel Processing (aka ATi Stream) for video encoding. The current AMD drivers do not allow HW acceleration to be enabled for video encoding on the Fusion APUs, and this is by AMD design.
I wish AMD, Cyberlink, Corel and the other companies promoting AMD APP would have been kind enough to point this out earlier. Take a look at this marketing brief…I would call it very misleading.
Transcoding is a very time-consuming and computationally intensive process. With the new AMD Fusion UVD 3 (Unified Video Decoder), and AMD Accelerated Parallel Processing (APP) technology, CyberLink PowerDirector the world’s first 64-bit video editing software offers up to 3.7x faster video rendering speed, allowing users to produce professional-looking videos in less time. MediaEspresso, universal media conversion software, now offers ultra-fast transcoding capability via the UVD 3 Decoder, enabling consumers to enjoy up to 2.75x speedup in performance, significantly reducing waiting time while giving users more time to share and enjoy their HD videos. [Ref: Cyberlink Press Release]
That’s a carefully crafted statement right there. PowerDirector does use APP, but only for some effects. You want to speed-up a section of video that has a fireworks effect on it, yes, PD9 will use APP to accelerate it. MediaEspresso doesn’t use APP. Al it uses are 1) The hardware video decoder which, when your output files are small and simple, provides a big boost. When your files are large and complex, 720 H.264 for example, the percentage advantage of the hardware decoder drops to almost zero. 2) It uses some “optimizations to enable Direct Memory Access between the CPU and GPU memory. Using DMA, we are able to save precious CPU cycles when the CPU is accessing the decoded video frames stored in the GPU memory.” Source: Cyberlink
So that clears up the question mark over my test results. Fusion enhanced video software can use 1) UVD, the hardware decoder, to accelerate decoding of source video 2) Some optimisations to speed up memory optimisations 3) Specific effects process written to use the APP API.
So will AMD Video Conversion (Avivo) support come in future driver sets? I also ask myself the question, if you can write code to implement affects enhancements, why can’t you write code to improve the video encoding process? Is this something this might come in the future? These questions remains unanswered for the time being.
End of Update. 07 April 2011
Update: 12 April 2011
It appears that I kicked a little bees-nest with this post as both Cyberlink and AMD have been in touch. The information and contact is much appreciated. Both AMD and Cyberlink wanted to clarify that the video encoding limitations don’t / won’t apply Fusion-wide. i.e. The E-Series APU that we’re testing here is aimed at consumer markets but there will be other products that will widen the use of APP.
The AMD E-Series parts are designed with the latest technology in their class making it a fully capable platform. While entry-level AMD VISION systems are capable of video transcode and editing, they are primarily designed with a focus on content consumption. VISION Premium and VISION Ultimate are the recommended systems for content creation. Upcoming AMD Fusion products designed for these mainstream and enthusiast markets will bring the capabilities of the current AMD Fusion products to new levels and introduce new and exciting levels of APP support.
So. Clearly there will be new products soon. I’ve been pointed to the AMD Fusion Developer Summit in a couple of emails so maybe they (AMD, Cyberlink) will be announcing new products then?
Cyberlink also sent a PDF which highlights the Brazos acceleration in their products. Here’s the diagram that shows the UVD (Decode) and DMA (Memory transfer) accelerations.
I posed a question to Cyberlink – can you do anything else to enhance performance through APP? The answer -They are looking at it and expect to implement for APP use in the future. Cyberlink are at the Fusion Developer Summit and holding a talk on Optimizing Video Editing Software with OpenCL. Details can be found in the event catalogue here.
End of update – April 12th
How stupid is that? AMD will be pleased to hear that that part of their platform is crippled on the Lenovo S205. Especially as they’re promoting it. (See Update above. The limitation was actually designed into Fusion from day 1)
Yes, I’ve tried updating all drivers but I can’t get the video encoding acceleration working at all even with new versions of Catalyst 11.2 or 11.3. I’ve tried 5 different software packages that claim to get a boost from the Fusion GPU but none of them get any speed increase at all. Some of them don’t even see the hardware.
I can get some specific code in one video editing program working (an effects overlay that is written to use AMD’s APP API) but that’s about it.
This is such a shame because the S205, when using Corel VideoStudio Pro X4 is really looking good even without the hardware rendering acceleration. The editing process itself is very smooth. There’s a need for some new profiles to enable my specific usage case and an SSD would improve the lengthy start-up time but I was seeing H.264 being rendered at 5mbps in 720p at about 3.7x real time. (slower than real time.) The rendering speed for 720p h.264 could be brought into the 2x range if Avivo was working and that’s very usable indeed.
My final test before sending the article out was to run the software again after a factory reset on the S205. I didn’t quite back everything up before I did it! I’ll bring you more details soon but right now I’m working on recovering 4-days of work on the article! Update: Looks like I lost it. I’ll put together a new one over the next few days. (See update above)
Many thanks to NotebookItalia.it who I discussed test results and thoughts with during this test. They have an article up showing vido rendering tests on C-50 and E-350 CPUs here. (Translation)
As part of my ultra mobile video editing project I’ve bought myself a second notebook. Previously I worked with the Acer Aspire One 522 based on the AMD Ontario APU. This time I’ve bought a Lenovo S205 notebook based on the E-350 Zacate APU and have moved up a notch in my search for a good-value, low-stress 720p editing and rendering solution.
Watch the unboxing video below.
Like the Toshiba NB550D I tested last week, the Lenovo S205 lightweight laptop feels like solid, a well-built device. I’m sure Lenovo could have shaved 100gm from the plastics but it looks like they’ve adhered to their build quality standards with the S205. The materials feel good, the finish is nice and the keyboard is a very high quality feature.
For 399 Euro you get the dual-core Zacate CPU running at 1.6Ghz with the Radeon HD6310 GPU with HD decoders. There’s 4GB of RAM, a useful 500GB hard drive (in two partitions with 400GB free on one, 27GB free on the other intended for ‘One-Touch Recovery’ images) and it’s running Windows Home Premium. The 11.6 inch screen has a useful 1366×768 resolution which, along with the excellent keyboard, reduces stress levels when sat down trying to create any sort of rich document where images, links and other items that need to be pulled together from various sources. Veriface facial recognition software is included which initially quite exciting to use but it’s much slower than typing in a password. One-Touch Recovery is software that can take a snapshot of the operating system drive and save it as am image. This is useful when you’ve got your initial build stable and efficient. A boot optimiser and power management application are included and there’s a DirectShare application which hasn’t been tested yet.
It does weigh 1.47KG though which is a noticeable step up from a 1.2KG netbook. Along with that, there’s a significant increase in battery drain meaning the rather low-end 48Wh 6-cell battery could be drained in 2 hours if you try hard. In a video rendering test with the screen and Wifi on I was seeing 16Watts being used which equates to 3hrs. After removal of McAfee and may Windows 7 effects, a reboot and a settling down period, I’m now seeing an average drain of 6W with Wifi off, screen on a 20% setting and the Livewriter application running. As a typewriter, you’re looking at about 6-7 hours of battery life. That’s quite the dynamic range there. Anything between 2 and 8 hours depending on usage! If only Lenovo had put a high-capacity battery in this. 60Wh would have permitted an ‘up to 10 hours’ marketing statement. 5hrs is the claim and that seems reasonable.
In terms of performance I’m seeing a good step up from AMD C-50 performance although there’s not much of a difference in CPU processing power to what I’ve measured on a dual-core N570 CPU that you’ll find in upcoming netbooks . 3D graphics performance is indeed impressive but not impressive enough to make this a full gaming device. It will certainly boost Google Earth, Cover-Flow and other 3D features in high-end applications though and it boost the UI experience well. Some gaming is possible but don’t expect to use high-end settings. Again, you’ll hit the 2hr mark when gaming so bear that in mind when mobile,
Here’s a comparison of the CrystalMark tests on a stock Asus Aspire One 522 (AMD Ontario C-50 CPU) and the Lenovo (AMD Zacate E-350 CPU)
Acer Aspire One 522, Left. Lenovo S205, Right. Click to enlarge. You can see 50-60% CPU performance increase (which relates to the 60% clockrate increase) and the disk and memory get a boost too. I’m confused about the open GL scores though. CrystalMark is quite an old test so perhaps the improvements aren’t showing up in this test.
Update: I was right to question the graphic scores. It looks like the ‘Power Play’ feature [available in the Catalyst Control Center] was set to restrict GPU performance. With ‘Power Play’ configured for max performance, the scores are very different:
For comparison, here’s the result from a dual-core N570 Atom CPU with Nvidia Ion platform (Asus 1015PN tested at CeBIT 2011) The results across the board match very closely. (See the update above, The Zacate APU outperforms the ION2 platform by a lot in the GPU tests)
I tried 3D Mark 03 on the Lenovo S205 but it crashed after the first test. 3DMark 06 was tested on the S205 over at Ndevil.com with a result of 1995 points. Interestingly, Netbooknews tested the NB550d, based on the Ontario platform, and saw 1889 points. Again I’m confused about the graphics performance here. Update: The results could have been due to the issue I experienced above.
A few more notes before we go into the video…
Fan On most of the time and varies in pitch a lot. Not annoying, but noticeable.
Screen Good clarity, contrast and brightness. Excellent side-to-side viewing angles. Opening angle not great, Hinges seem OK.
Mouse and mouse buttons Good quality. Small touchpad area might take some getting used to but it avoids accidental wrist touches.
Speaker (Mono I believe) OK for the occasional video, skype session.
Memory and disk not easily accessible
USB ports are 2.0 only
Bluetooth is 2.1 + EDR only
Comes with McAfee pre-installed.
Hard drive includes movement detection and protection.
Summary
While the AMD platform inside the S205 idles down nicely to show an efficient build, it’s capable of draining battery faster than any netbook I’ve seen. The 7 hour battery life seen when typing a document could drop to 2hrs when gaming. Heavy CPU usage will also push the drain up and the battery life down towards the three hours mark. Average battery life for the normal user looks to be about 20-30% less than on a 10 inch netbook, about 4 hours with the included 48Wh battery. If Lenovo had dropped in a high capacity battery we would be looking at a much more interesting 5hr figure but that’s not the case. I like the build quality and the 1366×768 screen is OK for my eyes at standard settings in this 11.6 inch frame. It’s also good for some applications that require 768 pixels vertically before they install or run.
Performance is good but not in a new league compared to the latest Atom N570 and Ion2 platform. I honestly expected more from the CPU and I’m confused at the 3D test results I’ve seen. In general, it’s a well-balance system and performs most daily tasks well. In my daily routine, a largely web-based office existence, the S205 performs well. The keyboard and mouse are impressive and when combined with the screen, it’s a noticeably less stressful experience than when using a netbook.
For the price, I paid 399 Euros, the Lenovo S205 is a high quality, well balanced and flexible device that offers enough power for everyday computing, some gaming and an impressive show of high-definition playback performance. It’s a sensible choice, almost boring, but one that will keep many happy and provide a good upgrade from a 2-year old netbook.
I was really expecting more from the E-350 CPU and it’s clear from early tests that this isn’t the comfortable, ultra-mobile 720p editing solution that I’m looking for. 3hrs rendering battery life equates to about 45 minutes of 720p video rendering. While that might be enough for a days worth of clips, it’s doesn’t leave enough battery life left for typing the articles (although there’s some scope for typing while rendering here it seems to multitask well.) Like the Dual-core Atom and C-50 devices, this is for 480p only and I’d class it in the high-end netbook performance category.
An SSD is going to boost startup performance nicely but with the disk appearing to perform well anyway, it may not be as noticeable as on some other devices. I love the build quality and want to keep the S205 but I know there are better solutions out there. Your suggestions for next-in-line on this test series are welcome! I’m looking at Corei3, i5 solutions next.
I took a step outside my usual 10 inch, 1KG zone today by buying an 11.6 inch notebook. I explain the reasons in an earlier post so I wont go over it again but suffice to say, there are good reasons for buying it.
I’ll be writing more about the device in relation to the AMD Brazos platform and its suitability for ultra mobile work and I’ll also be covering the device in a video-editing-related post. On that topic though, be aware that the video below was shot on a Nokia N8 phone and edited and rendered on the S205 in 720p
So far I’m impressed with the build quality, screen and keyboard (all very, very important) but not so impressed with the E-350 CPU performance. I expected more.
I’ll be doing more testing over the next few days so watch out for my review notes and impressions soon. In the meantime, enjoy the video.
