8.16.3 Intel Atom and Core M Processors

Intel is an American multinational company synonymous with PC and
microprocessors. Atom is the brand name given for the low power-
consuming and low-cost 32-bit and 64-bit chips manufactured for
smartphones and tablets.
Intel processors are based on X86 architecture which is more powerful
than ARM but consumes more power compared to ARM architecture.
The latest versions of Intel processors have reduced the power
consumption, bringing it down to less than 5 watts, which is ideal for
all mobile devices. Though Atom processors in the beginning supported
only Windows, they now support all major mobile operating systems.

Intel Atom processors are currently used in Atom X5 and X7 series. These chips are 64-bit quad
core processors in 14 nm size with speeds of up to 1.6 GHz that can be scaled up to 2.4 Ghz. Intel
also released Intel Core M ultra low-voltage microprocessors designed for ultra-thin notebooks,
mobile devices and 2-in-1 convertibles. The processor consumes 4.5 watts or less power, making it
ideal for long battery life. These are dual core processors with a speed of about 1.5 GHz which can
be scaled up to 3.2 GHz. Intel Core M processors offer 40% boost in CPU and graphics performance
as compared to the earlier versions.

8.16.4 Nvidia Tegra

Nvidia Corporation is a US-based technology company which
specializes in making processing units for graphics, gaming units
and mobile devices. Nvidia develops chips for smartphones, such
as transmitting fax, voice data, tablets and mobile devices under
the brand Tegra.

Tegra processors are built on 64-bit ARM architecture. Tegra has
already marketed Tegra 1, Tegra 3, Tegra 4, Tegra 4i, Tegra K1,
Tegra X1.

Tegra X1 is currently the most advanced Tegra chip in the market. The processor is Quad Core with
256 GPU cores and 4K video capabilities. The chips are built on 20 nm technology. The processor
is currently used in Nvidia SHIELD Android TV.

The Tegra processors mainly used in smartphones and tablets are Tegra 4, Tegra 4i and Tegra K1.
8.16.5 MediaTek

MediaTek is a Taiwanese semiconductor company providing
chips for mobile devices, HDTVs and other electronic devices.
