80% Rock Xtreme 685 Review
Source: Stuff TV English
Its big weight and low battery life limit the Xtreme 685, and if you're after a general purpose laptop you can get better built models for much less. What you won't find, however, is a better specced games machine for a similar price. Thanks to an excellent screen, great processor and exceptionally powerful graphics, it may not be pretty, but it's got a mean punch.

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.

Comment

Rock: Rock is a British laptop manufacturer and focusses the UK market.


These graphics cards are able to play the latest and most demanding games in high resolutions and full detail settings with enabled Anti-Aliasing.

AMD Radeon HD 6970M:

High-end graphics card from AMD based on the desktop HD 6850 with  UVD3 video processing and Eyefinity+.

AMD Radeon HD 6990M: High-end graphics card from AMD based on the desktop HD 6870, but with slower clock rates. UVD3 decoding and Eyefinity+ technology are still supported.

» Further information can be found in our Comparison of Mobile Graphics Cards and the corresponding Benchmark List.


Intel Core i7: The Intel Core i7 for laptops is based on the LG1156 Core i5/i7 CPU for desktops. The base clock speed of the CPUs is relatively low, but because of a huge Turbo mode, the cores can dynamically overclock to up to 3.2 GHz (920XM). Therefore, the CPU can be as fast as high clocked dual-core CPUs (using single threaded applications) but still offer the advantage of 4 cores. Because of the large TDP of 45 W / 55 W, the CPU is only intended for large laptops.  

2820QM: Fast Quad-core processor based on the Sandy Bridge architecture with an integrated graphics card and dual-channel DDR3 memory controller. 

Intel Core i5:

2540M: Fast Dual-core processor clocked from 2.6 to 3.3 GHz (Turbo Boost 2.0) based on the Sandy Bridge architecture with an integrated graphics card and dual-channel DDR3 memory controller.

3 kg:

This weight is representative for typical laptops with a 14-16 inch display-diagonal.

3.1 kg:


80%: This rating is not convincing. The laptop is evaluated below average, this is not really a recommendation for purchase.
