Chuwi HiBook Pro review: Core hardware and performance
Every tablet in Chuwi's range has the same core hardware setup, and it matches that of other cheap Windows laptops such as the Jumper EZBook Air.
You get an Intel Atom X5 Cherry Trail chip - the Z8300 - a quad-core processor clocked at 1.44GHz but able to boost to 1.84GHz when required. This is paired with 4GB of DDR3L RAM and 64GB of flash (eMMC) storage.
You'd therefore expect very similar performance between models, and that is largely what you get. This HiBook Pro didn't perform as well as its brothers in our graphics tests merely because we use the onscreen versions of GFXBench and it has a much higher-resolution screen. This may well have been behind its slightly lower performance in our other tests, too.
We run PCMark8 Home, Geekbench 4 and GFXBench to get an idea on performance. The Chuwi HiBook Pro reported 940 points in PCMark8, which is around 100 points lower than the HiBook and Hi10 Pro. Also see: Best Android tablets
A proper budget laptop might record double this score, such as the £300 Asus X55LA which recorded 2028 points. Tablets typically don't score as highly as laptops, of course, and the more expensive Asus Transformer T100HA scored only 1338 points in this test.
The HiBook Pro also gave a lower performance in Geekbench 4, scoring 2076 points against the 2144 of the Hi10 Pro. (We benchmarked the HiBook using Geekbench 3, which is not comparable with Geekbench 4.) As a guide, Geekbench 4 uses a baseline score of 4000 points set by the Intel Core i7-6600U, meaning the Atom chip inside the Chuwi tablets is roughly half as fast.
That might sound disappointing, but it's in real-world situations where performance can be more accurately assessed. The HiBook Pro is more than capable for productivity tasks such as working in Word and Excel, for browsing the web, for typing up emails, for browsing social media and for watching video. You wouldn't expect to be able to do much in the way of multitasking on this tablet, but lag was never an issue in our tests.
One thing you probably won't want to use the Chuwi HiBook Pro for is gaming, or at least not intensive gaming. Its Quad-HD screen slowed it down significantly in our graphics tests, meaning that it scored just 10fps in T-Rex and 4fps in Manhattan. We've seen sub-£100 phones do a better job of those tests.
To be fair, when running GFXBench's offscreen tests (recommended by GFXBench) the Chuwi HiBook Pro fared much better, and we recorded 22fps in T-Rex and 9fps in Manhattan.
Chuwi HiBook Pro review: Software
It might be called the HiBook Pro, but this Chuwi runs Windows 10 Home 64-bit, which it dual-boots with Android. Unfortunately it's old Android Lollipop (version 5.1 - we're now up to 7.0 Nougat), which reinforces the feeling that it's there as something of an afterthought.
You'll more than likely use the Chuwi HiBook Pro running Windows 10, which is much more up to date and better suited to productivity tasks. However, we like the fact that you can also use Android if you wish to, since there are a great many more apps available in Google Play then there are in the Windows Store.
Switching between Windows and Android couldn't be easier. When you boot up the tablet you are asked whether you want to boot into Android or Windows, and you can use either the volume button on the tablet or arrow keys on the keyboard to make your choice, then press the power button or Enter key to select. If you don't make a choice the tablet will simply boot into the last OS you used.
If you have already booted the HiBook Pro you can switch from Android to Windows by pulling down the notification bar and tapping Switch to Windows, or from Windows to Android by double-clicking the desktop shortcut. Do note that it must reboot to enter the other operating system, so it isn't a two-second affair and you should save any work in progress before doing so.
The tablet's 64GB of storage is split between the two operating systems, with the Chuwi reporting 44.1GB available to Windows and 9.72GB to Android. The maths doesn't quite add up there, but the Android partition doesn't appear to account for the OS itself, so we suspect the split is actually 50GB to Windows and 16GB to Android.
Of the 44.1GB assigned to Windows only around 18GB was free after installing our benchmarks, and around 9.7GB to Android. At least when using Windows you will likely want to make use of the microSD slot, attach a USB hard drive or use cloud storage before too long.
