Record: a laptop at 4.8 GHz

Maingear, assembler exercising his talents in the United States, recently began marketing the eX-L 17 3D, a laptop with a CPU is overclocked to 4.8 GHz. Yes yes, 4.8 GHz. This is an option, which dictates the choice of Intel Core i7 2920XM. This is Sandy Bridge CPU quad core, clocked at 2.5 GHz base, but rising to 3.4 GHz Turbo mode.

Maingear does not say so, but we imagine that the 4.8 GHz are also achieved more than the Turbo and not loaded with four cores. The performance gain is still impressive for a laptop. It is hoped that the cooling system will not be deafening. This orgy of CPU power is not unfortunately not reflected in the GPU.

Certainly, Maingear chose the most powerful graphics card of the moment (GeForce GTX 485M 2 GB), but remember the equivalent to a GTX 460 from office. Maingeat probably could provide superior overall performance by reducing CPU overclock, and allocating the thermal budget thus freed to overclock the GPU.

The base price of a 3D eX-L 17 4.8 GHz is $ 2700.
