The Intel Atom Z3590 with its PowerVR G6430 graphics processor is definitely very fast. It was faster than the honor 5X (Lowest Price) in all aspects of this benchmark, even though the honor 5X was powered by an octa-core Snapdragon processor. The ASUS ZenFone Zoom [Lowest Price] is just a little slower than the Samsung Galaxy S6.


Gaming Performance : 3DMark

We tested the ZenFone Zoom’s gaming performance using 3DMark, using the Ice Storm Unlimited test.

The Intel Atom Z3590 really showed its mettle in this test. While the PowerVR G6430 graphics processor held up well against the Galaxy S6’s Mali-T760 graphics processor, the Intel Atom Z3590 delivered much better physics processing capability than the Galaxy S6’s octa-core Exynos 7420 processor.


Our Verdict

When we first saw the ASUS ZenFone Zoom, we knew we had to review it. It is a remarkable combination of innovation and art. With its ox leather back, it looks like an ultra-premium version of the ASUS ZenFone 2 smartphones that came out in the past year or so.

Its killer feature is, no doubt, its 13 MP main camera with its unique and innovative periscopic lens design. This allows the ZenFone Zoom to deliver 3X optical zoom without a protruding or telescopic lens. It is capable of optical focal lengths of 28-84 mm while remaining a svelte smartphone no thicker than 12 mm. Amazing!

ASUS also threw in every photographic technology they had in their bag – laser auto-focus, dual-tone LED flash, and 4-stop optical image stabilisation (OIS). They even swapped out the dismal Toshiba T4K37 sensor for a much better Panasonic SmartFSI sensor. The result – the best photographic experience in the entire ASUS ZenFone 2 family.

The ZenFone Zoom’s image quality is significantly better than its ZenFone 2 brethren. Even its videos were much better – less grainy with better exposure control. The 3X optical zoom was very helpful in many situations, giving us greater reach and creative options. You will also appreciate the ZenFone Zoom’s 4-stop optical image stabilisation. It effectively cancels out your hand tremors, helping to deliver sharper images and videos.

While the Panasonic SmartFSI is a superior sensor, it is hardly the best sensor ASUS could have used. In a way, the ZenFone Zoom could have been better. It could have been the best camera smartphone in the market if ASUS paired it with top-of-the-line image sensor like the Sony IMX260 used in the Samsung Galaxy S7 edge.

Intel may be languishing in the smartphone market but there is no doubt that their Atom processors are fast. The Intel Atom Z3590 used in the ZenFone Zoom is a quad-core processor. But backed by the PowerVR Rogue G6430 graphics processor, it trashed the octa-core Snapdragon 616 processor used in the honor 5X (Lowest Price) while coming close in performance to, or even beating in some aspects, the octa-core Exynos 7420 processor used in the Samsung Galaxy S6.

Of course, all that processing power comes at a price – battery life. The ZenFone Zoom could only lasted 6.5 hours in our battery stress test (from 100% down to 20%). The 6″ ZenFone 2 Laser (ZE601KL) and the 5.5″ ZenFone 2 Laser (ZE550KL), in comparison, lasted just under 8 hours and over 12 hours respectively.

The good news is the ASUS ZenFone Zoom [Lowest Price] comes with fast charging capability. How fast? It recharges from 20% to 100% in under 1.5 hours! Even a quick 9 minute charge will give you a 20% boost in battery capacity. This is the best fast charging performance we have seen in the ZenFone 2 family.

The ASUS ZenFone Zoom [Lowest Price] is the ultimate smartphone of the ZenFone 2 family. It has the most powerful Intel Atom processor ever used in a smartphone, backed with 4 GB of RAM and a whooping 128 GB of internal storage. And it comes with a 13 MP camera with a 3X optical zoom, 4-stop image stabilisation, dual-tone LED flash and laser auto-focus. All in a sleek 5.5 smartphone form factor, wrapped in posh leather.

From what we understand, this is likely to be the last Intel Atom-powered smartphone to come out of the Intel-ASUS partnership. Of course, we hope that is just a rumour and the partnership will continue. But if it doesn’t, and you must have the best Intel Atom-powered smartphone ever made, the ASUS ZenFone Zoom is it.

We like it so much, we think the ASUS ZenFone Zoom [Lowest Price] deserves nothing less than our Reviewer’s Choice Award! Congratulations, ASUS!
