Cube i7 Book Full Review – Powerful Skylake Tablet with Wacom Stylus Support
Now equipped with an Intel Skylake chipset, the Cube i7 Book is now faster, runs hot and offers better gaming capabilities. It also offers Wacom Stylus support for Photoshop Softwares and other editing tools.
Great multitasking Performance (Intel Skylake Core M3-Y630)
Equipped with 4 GB RAM and 128 GB SSD Storage (Forsee)
Runs Cool on idle 40C
Runs Windows 10 Home Edition out of the box
Supports Wacom (1024) with Electromagnetic Screen (best suited for Photoshop)
Accurate touch screen with good viewing angles and image quality
Can play mainstream games with very good fps (Dota 2, Lol, etc…)
Convertible 2 in 1 tablet with Magnetic pin Docking interface
4 hours of battery life (average) – 4300mAh
Can get hot at heavy load (70 to 80C) – passive cooling
The Cube i7 Book or otherwise called Zealot is the successor to 2015 Cube i7 Stylus. Now, it comes with Intel Skylake Core M3-Y630 chipset and Intel HD515 that promises improve gaming and multitasking performance. The Tablet still offers the same Wacom Stylus support
Good build Quality and Design
The Cube i7 Book is a reboot, and thus, there really isn’t a lot of changes here. In fact, the major changes is only on the chipset. Anyway, the overall build quality is good and well built with no noticeable areas of cheap plastic. It has an all Aluminum back shell, however, it does have a bit of weight to it.
Inputs and Output
There are a couple of Inputs and outputs available here:
USB 3.0 Port – mainly uses an adapter to connect to peripheral devices
USB Type C Port (reversible Port)
MicroSD or TF Card Slot – supports up to 128 GB
5mm Audio or Earphone Port
DC 12V Charging Port
The Intel Skylake Core M3-Y630 is a laptop mobile CPU, probably comparable to a Core i3 chipset. It is coupled with an Intel HD515 Gen9 Graphics Chip. In terms of memory and storage, it has 4 GB LPDDR3 RAM and about 64 GB SDD Storage.
The Storage used is FORESEE which offers Good Write and Read speeds, mostly it has fast read speeds. On Crystal disk, here are the scores that I got.
Test Read (Mb/s) Write (Mb/s)
Seq 501.6 Mb/s 163.6 Mb/s
4K 128.9 Mb/s 111.8 Mb/s
Seq 418 Mb/s 157.7 Mb/s
4K 8.5 Mb/s 57.33 Mb/s
As you can see, the SSD is quick and has good scores especially on 4K. It does however have much faster Read speeds compared to Write speeds in comparison.
Benchmark tests results:
Cinebench: OpenGL (15.44 fps) and CPU (157 cb)
Geekbench scores: Single core (2645) and Multicore (4931)
Heaven Benchmark: 9 fps only on basic mode, 720p HD
No thermal Throttling on Aida 64 CPU Stress test (100% load on all CPU) – reaches 70C on full load
As you can see from the benchmark test above, the CPU is strong enough to handle most programs and tasks, it is in my opinion comparable to the Core i3 Mobile Chip. The overall experience was quite good, you can open multiple tabs on Google Chrome at the same time without any slow down issues.
Capable Gaming Tablet
Compared to the Cherry Trail Atom CPU’s, the Skylake Intel HD515 is much more capable of running the current generation games albeit low to medium settings. Mainstream games like Dota 2, LOL, Counterstrike way above the comfortable 30 fps range.
For example: Dota2 (1920 x 1080 pixels, lowest setting can achieve 50 – 80 fps) more info on the video below.
However, I would not advice 3D intensive games like GTA V
Strong Dual Band WiFi and USB Type C (Connectivity)
The tablets is equipped with Dual Band WiFi (Intel Wireless AC3165), and so far, I did not experience any disconnection issues or range problems. It readily connects to my wireless router and never did I experience connection drop. Furthermore, it readily supports USB Type C and USB 3.0 natively. However, using the USB 3.0, you will need a adapter or OTG capable to connect to it to other peripheral devices. Unfortunately, that is it, there is no HDMI Port available, so you can’t output your videos to other wireless TV’s.
Loudspeakers could have been better
The loudspeakers are the right side of the tablet, however, the sound quality and volume are relatively tiny and you can’t hardly make up if there is bass. Meaning, unless you are sitting close to the tablet, you can’t hear it properly. It is below average compared to the good sounding speakers of the Xiaomi Mi Pad 2. On the other hand, the 3.5mm Audio Port works just fine, the volume is good and there is no interference or static, as far as I have tested it. The quality also is also much better.
Thermals and heat output
So far at idle, using Hardware Monitor, I was able to get around 40C. On heavy load or gaming, it can reach up to a toasty 70C. Here are some situational temperature variances below.
Idle: 40 to 45C (cool to the touch)
Light to moderate load (Youtube streaming via Google Chrome) – 55 to 60C
Moderate load – using multiple tabs and programs at the same time – 60C to 65
Gaming – 65 to 75C (but may falter depending on the game being loaded, this is just based on Dota 2)
Especially on heavy load, the left hand side (where probably the Chipset is located) can get toasty, so if you are gaming, better place it on a table or matt. You would likely expect such temperatures because of the passive cooling type of the system used.
The keyboard and Wacom (untested sorry)
I am terribly sorry that I wasn’t able to review the Keyboard and Wacom stylus, as my package didn’t come with it. I will be showing it once it is available.
Battery life (more or less 4 hours)
It’s difficult to measure accurately battery life. As it is very variable and depends on your usage. But on casual use, like Websurfing, youtube, or watching movies on 25% brightness, you will probably get around 3.5 to 4 hours. On gaming however, probably around 2 hours at best. But for more frugal use, without wifi, you can get a good 4.5 to 5 hours of use, which is already pretty decent.
I would in a heartbeat pick the Cube i7 Book or Zealot as one of the best tablet I have tested of 2016. Even if it is just a reboot, it still offers superb performance for the price. The Skylake Chipset runs great on Windows 10 and Multitasking is a breeze. You can also game on respectable frames and wireless performance is also great. The Wacom stylus support means you can use it on Photo Editing softwares like Photoshop, but I wouldn’t recommend on Video Editing as encoding on it takes quite a while, you will probably be aiming for the Xiaomi Mi Air 13 when it comes to video editing.
