Rock Xtreme X 685-I5-2540M review

£1,249 inc VAT

Manufacturer: Rock

Our Rating: We rate this 4 out of 5

In terms of build quality, the Rock feels rugged - the chassis has a slightly rubbery feel to it and you'd certainly expect it to withstand continued use from heavy-handed or frustrated gamers.

The Rock Xtreme 685 is very much focused on gaming, and it certainly won't disappoint dedicated mobile gamers. In the FEAR tests the Rock achieved a remarkable frame rate of 131 on Maximum settings, with the Radeon HD6990 and its 2GB of memory doing a stunning job.

The 15.6in screen is also a corker, with a maximum resolution of 1920 x 1080 and an anti-glare coating on the glassy-finish screen that does a great job of reducing reflection while ensuring the colours remain deep. The sound quality is excellent. Unfortunately, there's no Blu-ray compatibility for the optical drive, which may prevent the Rock being a true multimedia all-rounder.

However, there is a dual-core Intel i5-2540M processor and 6GB of RAM, which combine to achieve a very respectable WorldBench 6 score of 124. However, the Rock is incredibly power-hungry. In our MobileMark 2007 tests, the battery was drained in just 2.5 hours. This might not seem surprising for a gaming-focused desktop replacement model, but we expect more from the huge 76Wh battery.

The hard disk is smaller than we'd hope for in a £1,000-plus model at just 500GB, although the Rock does include an eSATA port to give extra storage options. Of course the USB 3.0 interface is catered for as well. Should you want to hook the Rock up to a monitor or TV, there are HDMI and DVI connectors too.

In terms of build quality, the Rock feels rugged - the chassis has a slightly rubbery feel to it and you'd certainly expect it to withstand continued use from heavy-handed or frustrated gamers. The keyboard offers plenty of space between the keys, well-sized arrow keys and spacebar, and there's even room for a numeric keypad on the end. A fingerprint reader has been added for security. At 3.1kg it it’s far from the most portable laptop on test.

  • Overall: We give this item 8 of 10 overall

We can't help feeling that the Rock is expensive at £1249, though it does have an excellent graphics card and screen. We'd have liked to have seen a BD drive to expand the multimedia possibilities of this laptop. We've no complaints about the Core i5 processor or 6GB of RAM, but the battery life is a let-down.

  • Rock Xtreme 620 review

    Rock Xtreme 620

    British PC vendor Rock appears to be angling for a younger audience with its Rock Xtreme 620, packing a fast 2.53GHz dual-core Intel processor, ably supported by a powerful nVidia graphics card. It's the fastest laptop we've ever tested.

    A WorldBench 5 score of 83 suggests that the Rock is more than a dinky toy – for something this size, it's got impressive grunt.

  • Rock Xtreme XT

    Rock's Xtreme offers a top-notch specification and a price tag to match. At nearly £1,600 all in, the XT is aimed at people with slightly deeper pockets than most. Is it really worth the money?
