Jumper EZBook X4

That is the primary Gemini Lake laptop computer we’ve seen, though it doesn’t come from a mainstream pocket book producer, reasonably a Chinese language vendor known as Jumper which has produced quite a few gadgets – together with the EZBook three Professional, EZBook 2, EZpad 6 Plus and the EZpad 5S – which have obtained fairly respectable critiques up to now.

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 are going to discover out – there are some notable variations inside.


The strains 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 beneath) share the identical chassis which can be as a result of OEM (authentic tools producer) discounting or clearing out that individual chassis mannequin.

That’s to not say that this can be a unhealthy factor if it helps save just a few bob. However in a world the place everybody desires to be totally different, that is going towards the grain. So simply to recap, you get a steel chassis with a brushed aluminum end, embellished with silver strains, a notch beneath the (massive) touchpad, a reasonably skinny bezel, a single massive hinge, two microphones and one centrally positioned webcam. On the lid, you’ll discover the Jumper brand.

On the underside of the pocket book are 4 rubber ft, a flap that hides your SSD and a handful of screws that can help you open up the laptop computer. You additionally get a good array of ports (much like the F7): two full-size USB three.zero ports, a microSD slot, proprietary energy enter, a mini-HDMI port and an audio port.

We have been fortunate to have examined the Teclast F7 just some weeks in the past. We didn’t count on a giant soar in efficiency as Apollo Lake components make approach for Gemini Lake ones, and our benchmark outcomes are a combined bag (see beneath).

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

Utilization and efficiency

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

The influence 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 obtainable 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.

The audio system are fairly highly effective with little distortion and loads of definition, they usually 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 in regards to the lack of distinction and shade constancy.

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

Maybe the largest concern of all of them pertains to the trackpad. We discovered it to be inconsistent and unreliable, not like the F7 which makes use of the identical mannequin. It’s due to this fact more likely to be a hardware-based drawback which suggests 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 various from non-responsive cursor actions, or jerky actions, to unregistered clicks – these type 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.

The EZBook X4 is the primary Gemini Lake laptop computer to land in our workplace however the older technology continues to be good worth for cash.

Before everything, there’s the Teclast F7 which has an older CPU, the next price ticket ($300 – round £230) and primarily based on our testing, a a lot shorter battery life – however comes with 50% extra RAM and an arguably higher touchpad.

Should you don’t thoughts utilizing a pill PC with a keyboard and are pleased with a smaller show, then the Alldocube KNote 5, with a Floor Kind Cowl-esque keyboard, could nicely match the invoice at $310 (round £235). You’ll be able to’t improve the system reminiscence although and connectivity is restricted; however at the least you get 802.11ac Wi-Fi.

Jumper’s EZBook 3S comes with an older CPU primarily based on Apollo Lake however has 50% extra RAM, is marginally cheaper and packs a a lot larger SSD (256GB) which makes it a better option if you need extra storage capability. A less expensive model with 64GB eMMC exists – the financial savings on the EZBook 3 Pro are price it (nearly $90 – round £70), which you may spend money on a separate M.2 SSD.

The LapBook 12.3 from Chuwi is one other cheaper various. It has 6GB RAM and a smaller show however a a lot larger display screen decision (140% higher). The flipside is that it makes use of an older N3350 Celeron CPU and comes with a a lot smaller quantity of (a lot slower) eMMC storage. You’ll be able to add an M.2 SSD to it, although.

The enterprise take

Bar the touchpad concern, the Jumper EZBook X4 is a superb laptop computer for shoppers and companies alike. It has higher battery life, higher efficiency and is cheaper than the competitors – though not by a lot.

There’s not a lot that the fellows at Jumper can do to make the product higher as this specific combo has reached maturity. Should you can deal with the same old caveats related to buying from mainland China, then the EZBook X4 must be excessive in your record.
