Asus overview

Asus Padfone Infinity hands-on

The Asus Padfone Infinity comes with an improved screen, a handsome unibody, and a duly upgraded processor. The screen resolution is up from 720p to Full HD, for the much more impressive 441ppi. More importantly, the tablet half of the Padfone Infinity package has also seen a major bump in resolution to WUXGA (1920 x 1200).

The Asus Padfone Infinity feels great overall. The phone itself has a unibody design and is made of aero-space grade aluminum alloy, with a brushed finish. The aluminum edge has been anodized twice. We have to say the feel is top notch and the whole thing appears quite durable. The premium looks and the feel of cold metal in the hand are much appreciated.

The 1080p screen on the Padfone Infinity is superb. We didn't have that many gripes with the Padfone 2 but this one is so far ahead in terms of quality. Viewing angles are great on the Padfone Infinity, brightness levels look like a match for HTC's Super LCD 3 on the Butterfly and DROID DNA.

In terms of saturation the Padfone Infinity's screen is great but things aren't as overdone as on the latest HTC flagships. The screen easily puts the 5" 1080p Reality display of the Xperia Z to shame.

A look at the back

The back has a brushed texture. It allows a good grip and gives the device a high quality feel.

The tablet dock has been improved too. The materials look and feel unchanged - unlike the Padfone Infinity itself the slate is made out of plastic. We suppose Asus had to very much put weight into the equation too.

The biggest improvement is the screen. It's a huge step up from 1280 x 800 to 1920 x 1200. Pixel density doesn't come all that close to retina territory but is more than reasonable in tablet terms.

The Padfone Infinity tablet

Viewing angles are superb on the slate too, which is a rare thing to have in a tablet.

When docked the Padfone Infinity locks firmly into place. The Padfone 2 felt perhaps a tiny bit more secure - but it's by no means a deal breaker for the Infinity.

The Asus Padfone Infinity boasts a Snapdragon 600 chipset with four Krait 300 cores clocked at 1.7GHz. We ran some benchmarks to compare it against the HTC One and LG Optimus G Pro, which have the same chipset. The performance of the three as it turns out is not identical, instead each scores some victories. We guess it's a matter of what each company chose to optimize.

Anyway, the Padfone Infinity tops the Benchmark Pi and Linpack tests, which are meant to judge single and multi-core performance respectively. It lags behind in AnTuTu and Quadrant, however. These two test the overall performance of the phone.

We also ran a quick SunSpider test - and we do mean quick. The Infinity completes the test in 875ms, just edging out the iPhone and Windows Phone competition.

The Asus Padfone Infinity topped three of the benchmarks and we have to say it's not just synthetic performance either. The phone feels blazing fast in real life too.
