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 brought one of these tablets for $70 this week actually after a couple of promos from Microsoft. I wish that they had included an dongle where you can plug in an usb drive in it and an hdmi port. I have windows 8 pc's and using this windows 8 tablet is definitely a learning curve compared to Android tablets and ipads. I was surprised that windows 8 with 1gb of ram is responsive in this tablet assuming that you won't multitask that much.

    Since Microsoft gives out these windows 8.1 with bing licenses for free, I would imaging that we would see many Chinese tablets to get into this bandwagons for cheap tablets next year.

    I actually bought 2 of these of the kids for Christmas. One at $99 and one for $74 from the Microsoft store. I have been using a Nexus 7 second Gen for more than a year and have found it to be the perfect size. It is really just a glorified reader and Alarm clock. I use it to read the news and check email and occasional light gaming but never video or music.

    I figured for this purpose the Stream 7 would be fine and anything else was just a bonus. The Office subscription is a big plus as well. I have already set them up and tested them and am actually very impressed. I actually purchased a case ($10) Mini Bluetooth Keyboard with touch-pad ($30) and a 64GB MicroSD card ($25)

    As setup I was able to install Sims4 and Origin and the game actually plays pretty good. I installed Steam and The Swapper on the other and again works fine. Some of the Windows games are not bad either.

    Flipboard, Facebook and Twitter all work well as well as Nexflix, Hulu and Plex. Alarm Clock HD + was the best Alarm clock app I could find and it works great. Not sure I would ever use office on one of these without the Bluetooth keyboard but with the keyboard it would work fine in a pinch.

    I have a Microsoft Wireless Miracast dongle on my TV and the Stream 7 works perfectly with it. Even at the low resolution it looks pretty good streaming from Netflix. I was able to get it to run at 1080p as well but then you need the bluetooth keyboard.

    If you think of this thing as a PC it sucks but as a 7 inch table it really does what you expect of it and at $99 it is a bargain. The Metro app store is limited but the basic crap people really use is there. And if it is not you still have a browser and all the old PC apps that will probably run fine. The lack of touch support on the old games and apps may be an issue and some things don't size will to the low resolution but for what you are likely to use it for it is great.

    Was considering buying another Nexus 7 in case I broke my current one but would probably get one of these instead. I have several 10" Transformer tables and They are just too big for how I use a tablet. Even the 8" android and iPad Mini are just that much too big as a reader.

    "This wouldn't be an issue if these Windows tablets allowed you to directly move files to them from another computer over USB, but they don't."

    But they do. The micro USB port supports the "USB OTG" (USB On-The-Go) specification. With a simple adapter, the port can be converted to a full-size USB Type-A port, to which you can plug in whatever USB devices you want. (That's the extra bonus of it running full Windows 8.1.) I have used my HP Stream 8 with a variety of USB devices.

    Note: The Stream 8 is different than the Stream 7 in only three ways that I can find:
    1. It has a 1" larger screen (8" instead of 7", but with the same quality of screen.)
    2. It includes 4G wireless (HSPA+, aka "3.5G" to most of us,) with 200 MB per month free form T-Mobile. I have T-Mobile for my family, so I just pay the $10/month to duplicate the amount of data on my highest-data line.)
    3. It costs $179. (Which is a steal - since it costs $139 just to *ADD* 4G to an iPad.)

    Out of the box you can't do it, which is what matters.
  • PC Perv - Friday, December 19, 2014 - link

    Why not? All you need is a right cable. I am sure one will find such a cable for a lower price than Apple's Lightning cable's.

    You are such an ignorant and arrogant creature. Though I know why you want to disregard the utility of USB OTG. Which makes you a crooked creature on top of the aforementioned.
  • CharonPDX - Monday, December 22, 2014 - link

    Really? Then no desktop computer should ever have its utility on the internet considered since it doesn't come with internet built-in (you need SOME form of internet connection!)

    No printer should ever be considered worth using, because it doesn't come with paper in the box.

    A USB on-the-go cable costs all of $1.47 at Monoprice.

    I'm sorry, but that being your answer to my statement makes me seriously downgrade my judgment of you. Had you replied "I had forgotten about USB On-The-Go," I would have given you plenty of slack. But to completely dismiss an actually available core function completely, simply because "you can't do it out of the box," is rather haughty and dismissive.

    My Xbox is a crappy game system when it doesn't come with any games in the box.

    Using a USB On-The-Go adapter, you're limited to USB Hi-Speed speeds, but my USB 3.0 128 GB flash drive works just fine, and is plenty fast. In fact, it's almost certainly faster than the internal eMMC SSD. (Copying large files from eMMC to USB gets me about 27 MB/s. Copying large files from the USB to the eMMC is about 30 MB/s.) PLENTY fast to transfer large files.
  • Brandon Chester - Friday, December 26, 2014 - link

    It would be fine if the ability to send files from a PC via a direct USB connection was not an expected ability for a tablet, but it is. Alternatively, HP could have used faster and more stable WiFi and it would be a non-issue. Ferrying files between the two devices with a USB drive is a time consuming and cumbersome process, and having to go get additional hardware for it is an additional hurdle. I actually don't live near any electronics stores, so I would either need to drive a significant distance to get a USB-OTG adapter, or I would have to pay for one and have it shipped which takes time and reduces the tablet's price appeal, especially when paying shipping fees here in Canada.

    Mini related review:

    I bought the Stream 8, which is 1" larger, and includes HSPA+ "4G" service, for $179. My findings are near-identical to this review. The battery life is longer, and the back of the device fits better than Brandon describes the 7, but otherwise it seems the same to me, right down to the headphone jack noise issue. (I use Bluetooth headphones, so I mitigate that.)

    In the past year, I have switched between an iPad Air, a low-end Android tablet (the Air became my daughter's tablet,) to the HP Stream 8. I like the Stream 8 the best - even better than the iPad Air (and I was a 100% Apple user for personal devices prior.) I REALLY like having full-blown Windows available to me when I need it. I carry a small Bluetooth keyboard and mouse with me (Microsoft Wedge Mobile keyboard,) when I need to use it as a "real computer" rather than a tablet.

    The cellular connection is a nice bonus over the 7" model - and while the T-Mobile "free 200 MB per month for the life of the device" isn't much data, but it is a nice "lifeline" for emergencies. (I have a T-Mobile family plan, so I just added it to my family plan for $10/month.)

    Just as a quick note, maybe I got lucky. I'm watching Guardians of the Galaxy right now through headphones with absolutely no static issues whatsoever.
  • CharonPDX - Monday, December 22, 2014 - link

    I haven't listened to headphones often after the first couple times being static-driven. I was using Apple EarPods (because they're my standard "desk" 'phones at work.)

    I have now tried a few more, and the EarPods are the noisiest. Headphones that don't also have a microphone are the best, with some old-school Sony Studio Monitors (which are generally my best-sounding headphones every time,) having the lowest noise, but still having some.

    The Sonys, and a couple of the other "no microphone" ones are quiet enough that I can only hear the static during silent/very quiet periods.
