Why a 64-bit processor on smartphones is hype for now

Apple started a 64-bit processor craze by first putting one in the iPhone. Suddenly, ignorant reporters started asking if this new phone or that other one had a 64-bit processor. Knowing the industry well, it was expected that a slew of smartphones powered by 64-bit processors would hit the streets from other manufacturers.

And with CES 2015, they are here. Here is a list of newly announced phones packing one of those:

  • Asus ZenFone 2 – 2.3 GHz Intel Atom Z3580 processor
  • HTC Desire 826 – 1.7GHz Qualcomm Snapdragon 615 processor
  • Lenovo P90 – 1.8GHz quad-core Intel Atom processor
  • Vibe X2 Pro – 1.5GHz octa-core Snapdragon processor
  • Yezz Billy 5S LTE – 1.2GHz Snapdragon 410 processor
  • Acer Liquid Z410 – quad-core MediaTek MT6732 processor
  • Xiaomi Redmi 2 – 1.2GHz quad-core Snapdragon 410 processor

The 64-bit Processor Hype

A 64-bit processor on a smartphones is mostly hype for now though. Note that it does not offer speed performance improvements. Any differences in performance that you see between smartphones running a 64-bit and a 32-bit processor are due to the difference in processor clock speeds and RAM. Having more bits available means smartphones can potentially execute more complex instructions. Apps have to be re-written to execute those more complex instructions though, and most apps have not been.

So, for now, it is great to see these new processors, though they add nothing for now in terms of performance. Their existence, however, will motivate developers to play around with their apps. They are the future and we shall see the benefits over time. In the meantime, welcome these players to the 64-bit race.

    even running 32 bit code in 64 bit architecture will provide a significant speed boost

    1. You are wrong, sir. Comparing PC architecture to smartphone architecture is like comparing apples with oranges.

      A a 32-bit chip gives a device access to a maximum of 4 gigabytes. I m told that a 64-bit CPU boosts access up to 16 exabytes. The maximum RAM on smartphones is currently 4GB (one proposed 8GB RAM device was dropped), rendering a 64-bit processors a waste.

      The time for 64-bit processors will come. Not yet.
