ARM Says 2015 Will Be The Year Of 64-Bit Chips

ARM recently revealed a list of forecasts for 2015, and two of the more
interesting ones were the predictions about 64-bit chips. In the first
prediction, ARM said that as many as 50 percent of the smartphones being
shipped in 2015 will be 64-bit capable. In the second, ARM predicted that
smartphones that ship with both 64-bit chips and LTE modems will sell for as
little as $70.
After Apple launched its ARMv8-based 64-bit A7 chip in 2013, some companies
tried at first to deny that 64-bit support is an important feature for
mobile CPUs, while others started giving hints that they'll adopt 64-bit
chips as soon as possible.
More than a year later, and after Apple has already unveiled its second
generation 64-bit Cyclone, there are only a few different 64-bit CPUs on the
market. Those are mainly ARM's Cortex A53 for the low-end, and the Cortex
A57, usually coupled with Cortex A53 in a big.LITTLE configuration, for the
high-end.
There's also Intel's new Atoms for mobile; however, we're going to assume
that when ARM talks about 64-bit chips, it's likely referring to ARMv8 chips
. The company should have a good idea about the ARMv8 licenses that it will
give out in 2015, making it easier to have a forecast for ARMv8 chips alone.
We could count Nvidia's Denver as well, although that core seems to have
seen only a brief appearance on the market, inside the Nexus 9 tablet.
Nvidia has already replaced the Denver core in the Tegra X1 SoC with Cortex
A57 and Cortex A53 cores, and the future of Denver is now uncertain.
The other big prediction from ARM is the rise of the 64-bit LTE-capable
smartphone that costs only $70, making it possible for just about anyone in
the world to have a relatively fast smartphone experience.
The reason why this is important, especially for ARM itself, is because
ARMv8 is a whole new instruction set that adds more than just 64-bit
addresses. ARM wants everyone to switch to the new architecture as soon as
possible. This should increase the company's revenues, when everyone pays
for a slightly higher cost license, and it should also help app developers
focus on high-performance ARMv8 apps.
The two most popular operating systems running on ARM chips, Android and iOS
, both support the new ARMv8 architecture, so apps that take full advantage
of it should start to appear soon.
