Asus Transformer Pad Infinity 700 review

£599
Price when reviewed

Part tablet, part laptop, Asus’ split-personality Transformer devices deliver some welcome innovation in a sea of copycat tablets. They’ve never been cheap, but the latest Transformer Pad Infinity 700 – due for release on 31 August – ventures even further into premium territory by adding a glorious Full HD display and the latest Nvidia Tegra 3 processor to the mix.

Physically, the Infinity looks familiar. Brushed grey metal pools across the back, while a thick, glossy black bezel surrounds the display. Build quality is as solid as ever, with the metal chassis feeling stiff, sturdy and even reasonably light at 606g; the keyboard dock remains well built, the tablet slotting home with a cushioned click.

Switch on the Infinity and the new display leaps out immediately. With a 1,920 x 1,200 resolution across a 10.1in IPS panel, it effortlessly climbs to the top of the Android pile, making tablets with 1,280 x 800 displays look fuzzy by comparison. Text is pin-sharp and colours stunningly vibrant. It isn’t quite the match of the iPad’s 264ppi Retina display, but at 224ppi it isn’t far off.

In some ways the Infinity comes out on top, though. With the IPS panel at full brightness, we measured the Asus at 423cd/m[sup]2[/sup] with a contrast ratio of 940:1, only a smidgen better than the iPad. But with the Super IPS+ mode enabled, it rises to a searing maximum brightness of 650cd/m[sup]2[/sup]. Although that drops the contrast to 823:1, the payoff is legibility: even under direct sunlight, the Asus delivers a punchy, detailed picture.

The one weak point is backlight leakage – in the black bars above and below a widescreen video, we saw little pools of light straying in from the LEDs along the panel’s edges. It’s a minor disappointment on an otherwise exemplary display.

The screen is the headline upgrade, but there are other, more subtle changes. A 1.6GHz Tegra 3 T33 processor replaces the 1.4GHz T30 of the Transformer Prime, but the added graphical demands of the pixel-packed display mean you won’t notice the boost in everyday use. Nevertheless, this tablet shows Ice Cream Sandwich in its best light: the crisp front-end flicks back and forth with liquid smoothness, and jumping between applications is appreciably nippy.

The benchmark results show the Tegra 3’s power. Activating the Infinity’s High Performance mode saw it rack up a stellar 4,941 points in the Quadrant test, more than 1,200 ahead of the Transformer Prime. It isn’t as far clear in the SunSpider JavaScript test, but it’s still fast by any standards: a time of 1,871ms is just behind the fastest tablets out there.

Thankfully, the Infinity has its two batteries to cope with the brutish power and bright display, and Tegra 3 has a secret weapon: a fifth low-power core (dubbed the “companion core”) that does all the work at less demanding times. It’s an ingenious idea that saw the Infinity’s tablet part rack up 10hrs 7mins in our looping video test. After docking it in the base it went much higher, finally expiring after 16hrs 25mins.

In other areas, little has changed. The dock has the same old netbook-style keyboard and multitouch touchpad. The dock’s battery sends its juice to the tablet when connected, and you get a single USB 2 port for external storage and an SD card reader for good measure. On the tablet itself, there’s a micro-SD slot and a micro-HDMI port for viewing videos and photos on the big screen. The 8-megapixel rear camera produces crisp and detailed snaps, and the front camera has been bumped up to 2 megapixels. Bluetooth 3 is welcome, but the single-band 802.11n radio seems a touch stingy.

It’s a superb all-round package, but our appreciation is tempered somewhat by the price. As with previous Transformers there’s no option to buy the tablet without the dock, and Asus has no plans right now to release the 32GB model in the UK – so your only option is this 64GB model for £599. Apple’s 64GB iPad costs £550, and the 64GB Transformer Prime around £20 more, so you’re certainly paying a premium for the Infinity’s screen.

Yet, just as the iPad’s Retina display eclipsed the previous generation, the Infinity delivers a tantalising taste of Android’s potential. Where budget Android tablets often cheapen Google’s OS, the Infinity is at the other end of the scale, its glorious display and fast internals making for a slick, premium tablet experience. It’s never going to rival the Nexus 7 in the value stakes, but for those seeking the ultimate do-it-all Android tablet, at any price, the Infinity is the new benchmark.
