Powered by Intel. The Asus ZenFone 2 Deluxe is pretty well-equipped: Intel quad-core processor, 4 GB of RAM, 128 GB of storage, dual-SIM and PixelMaster camera. Has the manufacturer created a convincing overall package?
Asus ZenFone 2 Deluxe Review

Putting aside comparisons with the ZenFone 2, the Deluxe is a decent looking smartphone with good performance. Unfortunately, we aren't thrilled with the camera, and the user interface continues to be chock full of bloatware which is a serious blemish on an otherwise efficient system. For the similar pricing, devices such as the Honor 7 and OnePlus 2 offer a more rounded experience, with similar levels of performance, better features, better cameras and significantly better battery life. While the original ZenFone was a decent option at the time of its launch, the Deluxe feels dated and is outdone today.

ASUS ZenFone 2
Source: Hardware Secrets English
Launched last year, the ZenFone 5 was intended to be a smartphone with great cost/benefit ratio. In that, it was successful. Now, ASUS launches this new device, the ZenFone 2, which is very superior to its predecessor, not even being a replacement or a competitor in market. While the ZenFone 5 is a mainstream smartphone, the ZenFone 2 is close, in terms of hardware, to the top shelf smartphones on the market, with a lower cost.

So the Zenfone 2 Deluxe is an update of Asus' flagship phone only in looks but that's not necessarily a bad thing. It succesfully manages to make a plastic design feel a little more desirable without coming across as cheap and tacky. Along with an impressive specs list that's sill in tact and pricing that starts from around £230, this is an Android phone that's set up to punch well above its weight.

Imagination PowerVR G6430: Multi core (4 cluster) graphics card for ARM processors that supports OpenGL 4.x and ES 3.0

Only some 3D games with very low demands are playable with these cards.

Intel Atom: The Intel Atom series is a 64-Bit (not every model supports 64bit) microprocessor for cheap and small notebooks (so called netbooks), MIDs, or UMPCs. The speciality of the new architecture is the "in order" execution (instead of the usual and faster "out of order" execution). Therefore, the transistor count of the Atom series is much lower and, thus, cheaper to produce. Furthermore, the power consumption is very low. The performance per Megahertz is therfore worse than the old Pentium 3M (1,2 GHz on par with a 1.6 GHz Atom).

Z3580: Quad-core SoC for smartphones and tablets. Clocked at up to 2.33 GHz and integrates a DirectX-11-capable PowerVR/IMG GPU.» Further information can be found in our Comparison of Mobile Processsors.


This display is quite big for a smartphone but frequently used for smartphones.

Large display-sizes allow higher resolutions. So, details like letters are bigger. On the other hand, the power consumption is lower with small screen diagonals and the devices are smaller, more lightweight and cheaper.

Only few smartphones are more lightweight than this.
