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've been waiting for this for almost five years. I got a refurbished $200 netbook in the beginning of 2010, and then a $600 pocket netbook (Viliv N5) half a year later, and then a new $200 netbook near the end of 2011. This basically beats all of those, and at half the price.

    I bought HP stream 7 tablet and I am fully satisfied with its unbeatable productivity and performance compared to android tablets.
    I have used android devices for a while and now having HP stream 7 tablet in my hand for $100 it sounds unbelievable. In android devices either smartphone or tablet your productivity is limited badly. Here in HP stream 7 tablet you can enjoy full windows and can install all software. You don't need to accept any limitation as you can find countless alternative software if one wasn't good enough. Full Microsoft office, you cannot compare it with any toy software in android. You might spend $340 for Samsung Galaxy that runs android and you might gradually make yourself happy with whatever it gives you.
    I am very much impressed that I could run full windows and programming applications, unbeatable performance in playing videos and all these just for $100. I am really impressed.
    Android might be good for smartphone as the functionality is OK for phoning. However if you want to find, install and use anything else seriously, forget it.

    Sorry to hear about the poor audio jack. The one thing this device and the more expensive Dell VENUE Pro 8 Win 8.1 tablet offer that you can't get with any Apple or Android tablet is the ability to process any audio passing through it from any source on the way to the jack or to Bluetooth.

    I have an app that uses that capability which will make the cost of the device unimportant. The function alone will justify the cost. The Dell device has the DSP horsepower needed and I'll have to see if this one does even if it isn't yet a good platform for my app for electronic reasons.

    AnandTech / Brandon Chester - Have you thought about reviewing the Plugable Pro8 docking station that was a Kickstarter earlier this year? Now it's up on Amazon and is designed for the HP Stream 7 (and several other small Windows tablets) to both charge and provide USB device connectivity at the same time.


    Looking at the reviews, it should basically turn the Stream 7 into a much more capable little system.

    interesting nice read. using the hp gave a win8 education and it boots faster than my 2 samsung and asus tabs. a blutooth ms mouse fixes finger poking. a lenmar helix powercell fixes power worries. useful items for any tablet sit down session. for any oddities as mentioned the price was right or i wouldn't have one.

    It's 2017/5/4. I've had the HP Stream 7 for a year and it's been interesting. In the beginning it was little more than proof of concept. Windows 10 ran but it was a device plagued by hardware compatibility problems. Microsoft and its partners have done quite an impressive job in tracking down and rooting out hardware bugs. Hibernate/Sleep now preserve battery life for weeks on end. Recently the wifi connection became stable. Even certain aspects of Windows like Edge have become subtly more usable (though, Edge is still the epitome of mediocrity in terms of details like a non-functional Find and many web pages which don't work properly).

    The HP Stream 7 with Windows 10 is still nowhere near as usable as similarly spec'd Android or iOS device, but, it is functional in a pinch if you need to run older Win32 apps in a super portable device. I've run SketchUp and Excel to view documents, and, if you add a BT keyboard and mouse and you've got a super-portable MS Word word processor or PowerPoint designer.

    For a lark I put Halo: Spartan Assault on and it runs swimmingly. The only thing wrong with the game and the tablet is Windows 10 and how Microsoft cannot figure out how to disable edge swipes when the game is in full screen mode <droll laugh>.

    Windows 10 has improved since I first got the tablet a year ago. After recently doing a Fresh Start the OS runs a relatively lean 14.5 GB with 2.8 GB worth of apps (1 GB for Halo: Spartan Assault). There's still over 11.2 GB free. 300 MB of the 2.8 GB are the Mobile Word, Excel and PowerPoint, and, since it's a 7" tablet, those three are FREE edit-enabled versions even if you don't have an Office 365 subscription. They're not as full-featured as real Office, but, in a pinch they'll do.

    It's Feb 2019 and the original wave or Win tablets are still running - the Stream 7/8, Winbook 7 and 8, the Venue 8. I've got some observations as a long-time owner (but only occasional user) of each of these devices:

    1. HP blew it on the audio. The static crackle is still there. But now Mpow bluetooth earbuds only run about $18 on Amazon, so there's that. I even got a warranty replacement on the Stream 7 and it came back with the same static. It's not a constant, there are moments of audio clarity then the static kicks in.

    2. Windows 10 version 1809 is superb on these little tablets. About 16gb free on a 32gb version (only Dell offered 64gb versions). I had to wipe out the old factory recovery partitions and do clean installs.

    3. Driver support on Dell is awesome with occasional driver updates over the years and even includes Dec 2018 BIOS updates (Spectre Meltdown etc.). HP has drivers on their web page, but NO updates since 2015. Winbook you have to email MicroCenter for a "secret" link to drivers. Nuvision also lacks support.

    4. Running on 1gb on 32bit is like having hair transplants without local anesthetic. Consider this a "one app at a time" device and since Chrome opens instances for each new tab, consider limiting to just Facebook, just USA Today if you open tabs on those demanding web pages.

    5. 2gb on 32bit is faster than a netbook of yore, slower than a Chromebook on an ARM chip or an N3xxx processor. So, adequate. What 2gb/32bit lacks in speed, it makes up for in running 720p (and downconverting 1080P) H264 files, with subtitles, just fine. But not when downloading Patch Tuesday in the background! MPC-HC will handle the more stubborn files, the built in Windows player app can handle almost everything smoothly and has a better interface, and VLC is sort of ok.

    6. 4gb on a 64bit machine is like 2gb on a 32bit machine. What you gain in RAM you lose due to the extra demands of 64bit. So don't complain if your tablet "only" runs 32bit, it might be better performing.

    7. Dell Venue 8 Pro is limited to about 79% gamut BUT the color is very accurate. The HP Stream 7 is pretty terrible and is downright unusable unless you go into Control Panel, Display, and "calibrate" sop everything isn't lost in shadows during playback. The colors still seem weird after, but at least you don't feel like you are in a dark room without a flashlight.

    8. If you get used to the 2gb/64gb Dell Venue 8 Pro and then try the later, supposedly improved (but actually just cheaper) successor the 1gb/32gb Dell Venue 8 Pro, you will be able to measure the additional delays due to the retrench to 1gb with a hourglass - no stopwatch required. It is so slow sometimes I think it crashed. It WILL play Netflix, Amazon Prime, and run h264 just fine though. So long as it isn't Patch Tuesday.

    9. Don't mistake the puny 8" tablets with the fine Dell Venue 10 Pro (whether 720p with Bay Trail, 1080p with Bay Trail, 1080p with Cherry Trail and 4gb/128gb) which has a faster clock speed. Or with the Venue 11 Pro which is a mishmash of 2gb or 4gb, 32bit and 64bit, N3775 and N3795. All reportedly about 80% gamut. With the Dell Venue Pro 11 7140 they shot up to 100% color gamut and entry level was a Core M3, optional M5 and then i3 etc. IIRC. The Latitude 11 was born great, great screen and good Core M.
