The trend of the new processors to increase performance while decreasing energy consumption has decreased, and Intel has just introduced one of the most recent examples. In his Intel Developer Conference demonstrated the new architecture Haswell, to be available in 2013, which consumed so little that allow a notebook based on run for 24 hours on one charge in use, and no less than 10 days online waiting.


In fact, energy consumption is so low that the laptop can stay connected to Wi-Fi and check for updates, emails and synchronize files even while in the dream and the power available on standby is still sufficient to operate the CPU. This is what “Connected Standby” is about. Basically, the CPU can continue operating even when there is enough battery power to keep the screen on.

To demonstrate the low power of a system based on Intel needs a minimum connected Haswell Haswell system based on a small solar panel (about the size of a postage stamp) and a light source lamp. The system was running what appears to be minimal Windows system probably in a low power mode energy consumption, but it was enough to supply the window task manager and an animated GIF. When blocking the light source system froze, as it immediately cuts power source only. While this was a minimal system that shows how energy efficiency has come Haswell, and opens the possibility of laptops with embedded solar cells on its surface may continue to operate even when the battery runs out.

In addition to the ultra-low power consumption, which will be of great help to the growing market ultrabook, Intel promises “free performance”. Haswell 3D uses three transistors door who are making their debut in the new bridge Ivy processors coming out next year (which also significantly improve energy efficiency), and supports up to 8 cores. This probably means an increase in performance despite a significant reduction in energy consumption by a factor of 20 compared with the Sandy Bridge architecture today.

Haswell seems like a great way to make competitive Intel CPUs in the mobile computing landscape increasingly focused on ARM CPUs currently dominate, but are not the only ones making inroads. Qualcomm has announced the new Quad-Core 2.5GHz CPU for 2012 Snapdragon also reduce energy consumption and improves performance, and are mainly directed to the tablets.

Significant advances of this type are in fact an industry standard CPU, and show an exponential increase in performance per watt. This trend is largely what influences change fast track to mobile computing, where ultrabook tablets and smartphones seem ready to take control of desktops and laptops bulky. It is increasingly possible to put enough power within a ultrabook or tablets to become machines of the workstation level.
