previous 14nm chips. The upcoming Snapdragon 845
is said to be built on the 7nm manufacturing process,
and will be even faster and more efficient than ever.
(The nm figure relates to the distance between
transistors, and the more you can squeeze on to a
chip the faster it will be.)
Key new features offered by the Snapdragon
845 include a secure processing unit (SPU) that
Qualcomm says offers “vault-like security” with the
microprocessor, memory, crypto engine and random

Performance and battery life will also improve, thanks
to an octa-core Kryo 385 CPU with four 2.8GHz
high-power cores and four 1.8GHz low power cores;
the 845 is 30 percent more efficient than the 835 for
gaming, video and AR/VR, says Samsung.
Qualcomm’s new super-fast X20 LTE modem
is built-in, offering CAT 18 speeds of more than
