IBM and Samsung have announced a chip 'breakthrough' that has
the potential to keep smartphone batteries charged for an entire
week and extend the life of Moore's Law by a few more years.

The chip features a new Vertical Transport Field Effect
Transistors (VTFET) design, which lays transistors perpendicular
to the surface of the chip, allowing a vertical current flow.

The vertical design is the key to transforming the
semiconductor industry, as it could reduce energy usage
by 85 percent.

.. . .

Interesting design - vastly less power consumption at current
speeds - or much HIGHER speeds if you can afford to waste the
electricity.

The common "flat" transistors on chips waste power for a number
of reasons and capacitance/crosstalk issues also limit top speeds.
By standing the things up on end you can whip two problems at once.
However the fabrication tech needed to make 'vertical' FETs has
eluded everyone - apparently until NOW.

This IBM/Samsung alliance should prove incredibly profitable.
Makes most of the battery issues in portable devices go away.
The other big drag is the display - however quantum-dot and
other tech continues to be refined, slowly but surely reducing
the amount of energy-per-lumen required. But, for simple uses,
transflective LCD displays will do and they're far more energy
friendly than LEDs. 'E-Paper' also has a place for some low-
energy apps.

Intel/ARM ... I think they just lost the portables market.
They'll port Android or something for it Real Quick. Actually,
run in the higher-power mode, these chips may be two or three
times as fast per-watt as anything Intel/ARM/Nvidia has to
offer - pushing them out of most desktop/server markets too.

Big Blue apparently STILL has some tricks up its sleeve even
after all these years. Their R&D is the basis for lots of
products. And yes, it still sells "mainframes", nice dignified
black boxes about six feet tall, five feet deep and two feet
wide - link up to four of them together, IBMs OS or their
Linux (basically Red Hat now). Just what you need to run
global enterprises, defense networks etc.
