CPU Performance

Inside the Stream 7 we have Intel's Atom Z3735G, which is a quad core Bay Trail part that has a base frequency of 1.33GHz and a burst frequency of 1.83GHz. It's paired with 1GB of DDR3L-RS-1333 memory, where the RS stands for "Reduced Standby". As the name implies, it has a focus on improving standby battery life on devices like tablets. Z3735G unfortunately has one of the slower memory interfaces of the Bay Trail lineup, with only single channel support and a max memory bandwidth of 5.3Gbps. Nonetheless, the CPU itself is fairly powerful, especially for a $119 device. 

Although the Stream 7 does run a full copy of Windows, I've decided to run it through our mobile workflows rather than our desktop/laptop ones because I believe most users are going to use it similarly to how they use other tablets. I will elaborate on this point later in the software section, but the main point is that the normal Windows desktop experience is just not very good on touchscreens, especially 7" 1280x800 displays. Because of this, it's better to run it through benchmarks where it can be compared to other tablets. The fact that PCMark requires more space than the Stream 7 physically has is also an issue.

SunSpider 1.0.2 Benchmark  (Chrome/Safari/IE)

Kraken 1.1 (Chrome/Safari/IE)

Google Octane v2  (Chrome/Safari/IE)

WebXPRT (Chrome/Safari/IE)

As you can see, Intel's latest Atom platform performs very well in our tests. It should be noted that these tests were performed using Chrome rather than IE, to maintain consistency with the results from previous Windows tablet reviews. This means that the Sunspider score leaves much to be desired, as Google has stopped focusing on it as an optimization target. Looking at our other tests, we see that the Stream 7 is not the fastest tablet, but it is still very fast. In fact, it's competitive with the silicon inside tablets that cost two or even three times as much, which is impressive.

GPU Performance

The Intel HD Graphics chip in Bay Trail is architecturally similar to Intel's HD 4000 graphics on Ivy Bridge. It's simply a cut down implementation with 4 EUs instead of the 16 in an Ivy Bridge chip. The implementation in Atom Z3735G scales from 311MHz to 646MHz as needed. Thankfully, the Windows Store has up-to-date versions of 3DMark and GFXBench available, so we can compare the Stream 7 to the other devices that we've benchmarked in the past.

3DMark 1.2 Unlimited - Overall

3DMark 1.2 Unlimited - Graphics

3DMark 1.2 Unlimited - Physics

GFXBench 3.0 T-Rex HD (Onscreen)

GFXBench 3.0 Manhattan (Onscreen)

GFXBench 3.0 T-Rex HD (Offscreen)

GFXBench 3.0 Manhattan (Offscreen)

As you can see, Bay Trail isn't exactly a graphics powerhouse. However, the Stream 7's resolution means that the onscreen results aren't that bad, so you'll be able to get away with running some of the lighter games that you can on other platforms, provided of course that they're available on the Windows Store.

    I wonder if the headphone static is a problem with the Bay Trail chips or something weird with this zero cost version of Windows, because my Acer Iconia W4-820 also suffers from an annoyingly large amount of static over its 3.5mm headphone jack.

    Interesting. I have an Iconia W4 and haven't noticed the static. Does it happen to you at any volume level?

    If you live close to a MicroCenter, a much better pick would be the Winbook TW800 ($ 100). It's got a full USB 3.0, hdmi, micro sd, ips. In my opinion, it's by far the best $ 100 out there. Otherwise i would add extra $49 and buy <a href="http://www.amazon.com/gp/product/B009X3UW2G?ie=UTF... Asus Nexus 7</a>. It's faster and better value!

    Whether it is a better value depends on user, I prefer the full windows 8.1 on my Linx 7, bookmark bar in IE synchronizes with my desktop pc as well as bunch of other things. It is just nice to have a proper PC in pocketable form factor. I have even found a very nice touch screen touchpad in windows store for mouse cursor navigation, handy when you connect external screen and extend the desktop. I just really love this cheap windows tablet. Linx 7 is sooo nice, 280g of full PC experience goodness :-) I have even sold my very good touchscreen Dell e5440 because it became obsolete to me, still keeping hi end mini itx desktop.

    With HDMI and full size USB, I thought of getting one of these to use with external monitor and wireless keyboard/mouse.

    At $100, the TW800 WinBook only has 1GB RAM and 16GB eMCC storage. Even after tuning, Win 8.1 will use 95% of the storage and adding microSD only good for saving photos, documents.

    For $200, you can get the TW100 WinBook that comes with 2GB RAM and 32GB eMCC storage, which will allow room to run additional software.

    Did my homework and just purchased a Dell Inspiration NoteBook for $300. that included a Haswell i3 processor, 15.6" touch screen, 4GB RAM, 500GB storage, HDMI, 3 USB ports including one 3.0), optical DVD drive, 4 cell battery etc.

    Bought one of these on BF, on sale from Office Depot for $79. Tried it for a few weeks, and I'm shipping it back to them today.
    Frankly, I was underwhelmed with it. As pointed out in the review, battery life is dismal.....even when it's on standby! While I wasn't using it every day, I did try to pick it up whenever possible, to attempt to immerse myself in the Windows 8 experience, as this was my first W8 device. But it seemed as though every time I picked it up to use it, I had to plug it in and charge it first! Sorry, but sitting there, doing NOTHING for 3 days, and the battery dies (from WHAT??) is NOT acceptable to me.
    As I already said, this was my first W8 device.....and will likely be my last one, too. I know, I know, some people are enamored with it, and think it's the greatest thing since sliced bread. But I'm just not impressed with it (and this is the improved Windows 8?? yikes!). I have used pretty much every version of Windows since 95, and found this one to be the least intuitive one of all. Hopefully Windows 10 will bring back some of the simplicity of the older versions!
    As I said, this is being shipped back today. I did a refresh of the operating system (to wipe my info off of it), boxed it up, and Office Depot is paying the return shipping. In its place, I'm looking at the year old Asus 7" tablets, running Android. I've owned one of the newer 10" tablets made by them for almost a year now, and have been much more impressed with their products, as well as their value, than any other manufacturer out there.

    I actually have this tablet, been using it for a couple of weeks now. Not bad at all,, Have a 64gb Samsung SXDC UHS-1 card in it. Actually use it to program radios in the field by way of USB-OTG adapter. Use my phone as a hotspot whenever I need to do something online. Not bad for something I picked up from Microsoft for $100. Oh by the way, I'm posting this comment thru it.
  • kg4icg - Monday, December 22, 2014 - link

    By the way, only the Back cover is plastic, the frame is metal, possibly aluminum. A Plastic tablet this size is half the weight, Namely the Samsung Tab 4.

    I recently bought a DVP8 on-sale (wanted more RAM) but considered the Stream 7.

    I justified it as a Raspberry Pi with a built-in screen. I mean outfitted with a case you are spending $35 to 45 for that Pi Whats another $50-60 for a multi-touch screen if you have a use for it? If you don't, obviously don't spend on it. I bought it to be a replacement for a squeezebox touch, which this does superbly.

    It comes with a Windows License which is handy, you can still get Linux on it if you want the lighter-weight OS... I think the UX is rough using desktop Windows with touch. They really should have put the keyboard on the charms bar rather than taskbar as you'll be using it alot if you don't use a bluetooth keyboard.

    My only complaint is the OS is not a "pro" license so I had to use Team Viewer rather RDP to connect to my device.

    So glad you guys reviewed this! Very disappointing that the headphone jack is bad. Everything else seems...well, not bad or even good for a $100 tablet, but not being able to use this for media, when otherwise it would be AWESOME for media since it's real Windows kind of kills it for me.

    Meanwhile I think it was Toshiba has a cheap 7" one too but it's killed by using a 1024x800 (?) screen with a higher resolution scaled down to it. Seems like it both cases spending the extra $60 or whatever for the 8" tablets would be the way to go (assuming the 8" models don't have these problems).

    Worth noting that actually the Windows desktop is VERY useable on a 10.6" screen...it even works pretty well through my iPad's 9.7" screen with remote desktop. (The issues there are more just that there's a bit of lag/weirdness since it's sending touch commands across a wifi network!)
