Exclusive review: Crossfire notebook Cizmo AX17
Premiere at PCGH: We test the first Radeon HD 3870 based Crossfire notebook. Can the GPU duo beat Nvidia's Geforce Mobile?
Cizmo delivered another high-speed gaming notebook. The AX17 uses, in contrast to our last sample, an Ati graphics solution. As the first notebook it delivers two RV670 GPUs running in Crossfire mode. But that costs: Like many other high-end gaming laptops it weighs about 4.5 kilograms. The price on the other hand seems quite reasonable. According to Cizmo the basic configuration with the Crossfire solution will be sold for €1799.
The case of the built is made of plastic that is covered with a glossy black finish. Looking noble at the first glance, a closer look reveals that very fingerprint is visible, especially on the big hand rests.
Intel's Centrino 2 platform (Codename: Montevina) is the base for the system: The socket of the new PM45 chipset holds a Core 2 Extreme X9100 with 3.06 GHz, 6 MiByte L2 cache and 266 MHz FSB. Four GiByte DDR3 1066 memory (8-8-8-20) provide a steady data transfer, but because of the preinstalled Windows Vista x86 they aren't fully used.
An interesting option is the possibility to choose the multiplier in the BIOS during boot up. Settings between 6 and 12 - without 0.5 intermediate steps - are possible, although the default value of the X9100 is 11.5. This reveals a naming bug: if 6 is set, the system runs at 266 x6 resulting in 1.6 GHz in Windows. Changing to 11 in the BIOS results in a multiplier of 11.5 and the default clock speed. Accordingly the - not specified - overclocking function is the multiplier setting 12, which actually is a 12.5 that sets the clock speed to impressive 3.33 GHz.
The graphics solution is not a Radeon X2 for notebooks. Cizmo uses two individual Radeon Mobility HD 3870 that share a cooling solution - the Catalyst Control Center (CCC) calls them X2 nevertheless. There are some differences compared to the desktop version: According to the CCC the GPUs are connected with eight PCI-E lanes each and the GPUs are clocked with 660/850 MHz (Desktop: 825/900 MHz) in order to reach a lower TDP. Each GPU can access 512 MiByte memory.
