Deviltech Devil 9700 DTX HD 5870 (W860CU) Notebook

After a seeming eternity, the first notebooks with ATI's fervently awaited Mobility Radeon HD 5870 are finally available. We've snatched the Devil 9700 DTX, a correlating sample from Deviltech, and have taken the Radeon HD 5870 to its limits of gaming capacity. As many other suppliers (mySN, Notebookguru, Cyber-System, Hawkforce etc.), Deviltech allows the used Clevo barebones to be configured in many various ways (in this case, the W860CU). Intel's latest Core i5 and Core i7 range is available as the processor. This ranges from the dual-core Core i5 520M with 2.40 GHz up to the wickedly expensive quad-core Core i7 920XM with 2.00 GHz for the Devil 9700 DTX. The customer can choose among a DirectX 10 capable GeForce GTX 285M and a DirectX 11 capable, brand new Radeon HD 5870 as the graphic card.

As usual, the DDR3 RAM ranges from two to eight GBytes, the hard disk capacity from 80 GBytes (SSD) up to 640 GBytes (HDD). A common DVD burner is built into the standard configuration as an optical drive. However, a BluRay drive or BluRay burner can be integrated for a surcharge. Finally, WLAN, just like the operating system, costs extra. However, you tie yourself to a 15.6 inch FullHD display (1920x1080) with a glossy finish for the display.

The Devil 9700 DTX starts at a price of 1329 euro, but the price can quickly rocket to several thousand euro in the according configuration. Our prototype with a Core i7 820QM, Radeon HD 5870, a 4 GByte DDR3 RAM, a 320 GByte HDD (7200 rpm) and Windows 7 Home Premium 64 bit added up to a stately 1841 euro at the time of the test.

Deviltech has bestowed us with the currently second fastest mobile quad-core processor, which is the very strong Core i7 820QM. The Core i7 820QM has a clock rate of 1.72 GHz and has, in opposition to the favored Core i7 720QM model, not "only" a 6 but an 8 MByte L3 cache right away. However, the TDP is identical with 45 watts. Merely the top model, Core i7 920XM, consumes even more energy with 55 watts. Whilst the currently fastest dual-core model, Core i7 620M, is already manufactured in a cutting edge 32nm process, the Core i7 820 QM is still based on a 45nm structure width.

But now to the highlights: Due to the hyperthreading technology, the Core i7 820QM can call on four additionally simulated cores beside its own four cores and thus manage up to eight cores at the same time. However, the benefits are limited to optimized applications, though. Far more interesting for gamers would be the practical turbo mode, called "Turbo Boost", which provides for an automatic CPU overclocking from 1.73 up to 3.06 GHz. Because the waste heat increases considerably during such an overclocking, experience has shown that the Core i7 get very hot and forces many cases to their thermal limits. The result: The turbo mode remains disabled under high load in many notebooks or only provides (if at all) for a very moderate overclocking.

Deviltech relies on the now finally available and, at the date of testing, fastest single graphic card, the Mobility Radeon HD 5870 from ATI. Whilst the Nvidia competitors only serve with support for DirectX 10.1, the HD 5870 is technically superior with its support for the current DirectX 11 interface. As its predecessor, Radeon HD 4870, the HD 5870 can fall back on 800 unified shaders. In return, the clock rate has increased considerably from 550 MHz (core) and 888 MHz (memory) to 700 MHz (core) and 1000 MHz (memory). However, the memory bus has been halved from 256 to 128 bits. But because of the applied GDDR5 VRAM this circumstance doesn't turn into the proverbial bottleneck, as the GDDR5 can score with a high memory bandwidth.

The manufacturing process of 40nm is very low. The HD 5870 treats itself to as much as 60 watts anyway. Thus, fairly long excursions remote from the mains can only be realized with a powerful battery. Just one more note: The Radeon HD 5870 might overall be very fast for notebook conditions, but it can only line itself in among the good, but not overwhelming, Radeon HD 5770 in comparison to the desktop range.

A four GByte random access memory, consisting of two modules with a 2048 MByte DDR3 RAM (1333 MHz) each, support the processor and graphic card. More main memory currently isn't needed for even demanding games.
