What is the difference between the Boox Tab X and the Boox Tab Ultra?

The Tab X and Tab Ultra are two of the newest E-ink writing tablets to be launched by Onyx Boox (and they are both on my list of the Top 5 best devices). Because Boox’s naming conventions are not always intuitive, in this blog post I want to highlight the main differences between the two devices.

First, the similarities…

Both the Tab X and the Tab Ultra use Boox’s latest technologies to enhance the user experience by making it smoother and easier to use.

This includes Super Refresh technology (both a graphics processor and improved software) to improve screen refresh rates and a user interface that supports widgets and customisation to resemble the home screen of other Android devices closely.

They also both have built-in speakers, a microphone, frontlight WiFi, Bluetooth and USB-C. They also have a G-Sensor automatically that flips the screen between landscape and portrait mode when the tablet is rotated.

Under the hood, they both use the same 1.8GHz octa-core processor and have 128Gb of storage space along with a powerful 6300mAh battery.

They also both ship with Boox’s Pen2 Pro stylus (which has an eraser at the top).

On to the differences…

The main difference is that the Tab X has a larger 13.3″ screen (A4-sized) compared to the Tab Ultra’s 10.3″ (A5-sized) screen. This means that the Tab X has a larger canvas area for writing and a higher screen resolution, however this does mean that pixel density is ever-so-slightly lower.

The Tab X uses a Mobius Carta e-ink screen/backplane compared to the Tab Ultra’s glass Carta HD screen. This means that the Tab X screen is a bit more flexible and less likely to break under stress.

Both devices have a similar thickness, but because of the larger screen on the Tab X, the dimensions (footprint) and weight of the device are bigger.

The Tab X also has 2Gb more memory than the Tab Ultra.

The Tab Ultra has some additional hardware features that aren’t available on the Tab X, including a rear-facing camera for scanning documents and a slot for a MicroSD card for file transfers and to expand storage capacity.

The Tab Ultra is also designed to work seamlessly with a magnetic keyboard/case. The Tab X does support third-party Bluetooth keyboards, but Boox does not manufacture one. In addition, the Tab X is not magnetic, so the stylus will not attach to the side of the tablet (as it does with the Tab Ultra).

In terms of price, the Tab Ultra is around $600USD, and the Tab X is Β£880USD.

Dan Dutton is passionate about E-ink writing tablets, which bring together the pleasure of writing on paper with the power of digital technology. When he bought his first tablet, he realised that there wasn't a lot of unbiased information available for people that were considering buying an E-ink tablet, and so he built eWritable.
