The EZBook X4 is the observe as much as the EZBook Three Professional and makes use of precisely the identical chassis because the Teclast F7 though – as we’ll discover out – there are some notable variations inside.


The traces between producers and designers of laptops have blurred and this helps to elucidate why there are such a lot of laptops which share the identical design.

The Teclast F7 and the EZBook X4 (pictured side-by-side under) share the identical chassis which can be as a result of OEM (unique tools producer) discounting or clearing out that individual chassis mannequin.

That’s to not say that this can be a dangerous factor if it helps save just a few bob. However in a world the place everybody needs to be completely different, that is going towards the grain.

Right here is the Jumper EZBook X4 configuration despatched to TechRadar Professional for overview:

Digicam: 2MP entrance webcam

Weight: 1.36kg

Dimension: 333 x 220 x 13mm (W x D x H)

Battery: 9600mAh


We have been fortunate to have examined the Teclast F7 only a few weeks in the past. We didn’t anticipate an enormous soar in efficiency as Apollo Lake elements make manner for Gemini Lake ones, and our benchmark outcomes are a combined bag (see under).

Jumper has bundled a 12V,2A energy provide unit that’s a lot smaller than your common PSU, and that’s nice if it’s important to transfer round. The keyboard is a backlit mannequin with two lighting strengths (use Fn + area to set off it) and enormous keycaps, whereas the touchpad is generously proportioned.

Utilization and efficiency

Compute efficiency usually appears to be barely higher than the older N3450-based laptop computer, however video numbers are down for some cause, generally by as a lot as 25%, which is puzzling provided that each the UHD Graphics 600 (on Gemini Lake) and the HD Graphics 500 (on Apollo Lake) are very related.

The impression of much less RAM (the X4 has 4GB of RAM, the F7 has 6GB) would possibly clarify some efficiency discrepancies, particularly when contemplating the quantity of accessible system reminiscence. You’ll be able to improve the reminiscence, although, which is a boon in comparison with sealed rivals.

The on-board battery is a 9.6Ah/49Whr mannequin whereas wi-fi connectivity is assured by the ever-present Intel Wi-fi-AC3165 module which, as its title implies, delivers 802.11ac Wi-Fi.

Right here’s how the Jumper EZBook X4 carried out in our suite of benchmark checks:

Passmark: 992

Passmark CPU: 2102

CPU-Z: 132 (single-thread); 465 (multi-thread)

Geekbench: 1854 (single-core); 5217 (multi-core); 5944 (compute)

Cinebench: OpenGL: 11.74 fps; CPU: 178

CrystalDiskMark: 561MBps (learn); 473MBps (write)

Novabench: 654

Atto:  565MBps (learn, 256mb); 474MBps (write, 256mb)

Home windows Expertise Index: 4.5

The audio system are moderately highly effective with little distortion and loads of definition, and so they nestle close to the bottom of the show.

Talking of the latter, Jumper judiciously opted for a 14-inch matte Full HD show with a fairly vibrant output. It’s ok for non-professional duties though extra demanding customers would possibly complain concerning the lack of distinction and colour constancy.

Contact typing on the keyboard is fulfilling. There’s good suggestions, respectable journey and sufficient distance between the keys. The one niggle we’ve is the truth that the keys are silver coloured, and white characters on silver isn’t a terrific thought, particularly in vibrant daylight.

Maybe the most important subject of all of them pertains to the trackpad. We discovered it to be inconsistent and unreliable, in contrast to the F7 which makes use of the identical mannequin. It’s due to this fact more likely to be a hardware-based drawback which implies that it’ll solely be resolved by way of an up to date mannequin. Or we may have obtained an X4 with a dodgy touchpad, wherein case, one can query the agency’s high quality management processes.

The issues we encountered diverse from non-responsive cursor actions, or jerky actions, to unregistered clicks – these kind of annoyances.

Battery life was wonderful, exceeding six hours taking part in our YouTube count-up file at 100% brightness with the slider as much as finest efficiency.

  1. Anyone had a chance to run Linux on the EZbook X4 recently? -Back in July’18, reports still were that the touchpad went unrecognized by Ubuntu et al, due too new ELAN-touchpad hardware.
    As I’d like to use the EZbook for Linux Mint, this would be a show-stopper..
