ARM version of Windows will bring the concept of the big.LITTLE PC

Microsoft, introducing Windows on ARM, in partnership with Qualcomm, stressed that almost everything will remain unchanged, except for the ability to run Windows 10 on a completely new processor architecture while maintaining compatibility with the x86 ecosystem programs. However, it was presented to the new Windows, but are well known in the mobile market, the concept of a Central ARM processor big.LITTLE.

This technology is designed to significantly reduce average power consumption through a combination of high-performance cores with more power efficient small cores, as well as to expand multi-threading mobile processor. For the first time such technology (vSMP) has spread to the mass market, thanks to NVIDIA CPU in its Tegra 3 chip.

Latest software and hardware platforms big.LITTLE, automatically distributing tasks between cores, can save up to 75% of the energy in the scenarios of low and medium loads and 40% increase in performance in highly parallel workloads. Technology allows us to produce processors designed for a new level of peak performance while maintaining a familiar user of indicators of autonomy of mobile devices.

According to Qualcomm, the main advantage of laptops with Windows 10 on ARM platform will not only be reduced size and weight, but in the 4-5 times increased battery life in Connected Standby state, more typical of smartphones than traditional PCs.

The number of certified Windows 10 for ARM processors until one is Qualcomm Snapdragon 835that provides 4 high performance and the same energy-efficient cores. Qualcomm notes that this scalable architecture perfectly corresponds to the traditional scenario of the processor with a high degree of load imbalance and under normal use will provide the computer for the whole day.

Due to the high integration of the components of the SoC Gigabit LTE modem, GPS, Wi-Fi, Bluetooth and so on — by 30 % reduced PCB size, the laptops will get a new, hitherto not built in, possible, more capacious battery and the lack of an active cooling system.

It is expected that by the end of the year ASUS, HP, Lenovo and Microsoft itself will present to the public the first computers on the Windows platform on ARM. If successful, this concept of traditional processor architecture can obtain a serious competition, raising the question of the very survival of x86 in the consumer market.
