ARM’s New CPUs Force Android Phone Makers to Go 64-Bit Only

ARM, a leading semiconductor and software design company, has sent a clear message to Android phone manufacturers who have yet to embrace 64-bit technology. The company has introduced its first lineup of CPU core designs that are exclusively 64-bit, leaving behind legacy 32-bit technology. The Cortex-X4, Cortex-A720, and Cortex-A520 cores may not represent significant performance leaps individually, but they are expected to set the pace for the future of Android devices.

The Cortex-X4, designed as a performance core targeting flagship phones, builds upon the success of its predecessor, the X3. With an updated architecture, ARM claims a 15 percent increase in performance while consuming 40 percent less power compared to its predecessor. This enhancement translates to faster app launches and a more responsive user interface, potentially leading to improved battery life during resource-intensive tasks such as gaming.

In the lineup, the Cortex-A720 serves as a successor to the A715 “middle” core responsible for handling most computing tasks. While it offers improved performance, ARM’s primary focus with the A720 is on power efficiency. ARM claims that the A720 is over 20 percent more power-efficient than its previous design. Chipmakers also have the option to utilize a smaller ‘entry’ version of the A720 to reduce costs or shrink the hardware footprint.

ARM’s attention to power efficiency extends to the Cortex-A520 efficiency core, which is primarily intended for low-demand background processing and other lightweight tasks. However, reports suggest that the A520 outperforms its predecessor, the A510, by eight percent while offering a remarkable 22 percent increase in efficiency. This improvement indicates that even casual smartphone users can expect extended battery life on their devices.

The introduction of ARM’s exclusively 64-bit CPU core designs marks a significant milestone in the evolution of Android devices. As the Android ecosystem transitions away from 32-bit technology, manufacturers will be compelled to adapt to ARM’s 64-bit architecture to stay competitive and deliver optimal performance to their customers. ARM’s commitment to power efficiency across all core designs reinforces the importance of maximizing battery life, a key factor for smartphone users.

The Cortex-X4, Cortex-A720, and Cortex-A520 cores are expected to set the standard for Android devices in the near future. Manufacturers will incorporate these core designs into their upcoming smartphone models, providing users with enhanced performance, improved power efficiency, and extended battery life. As the Android landscape continues to evolve, ARM remains at the forefront of semiconductor innovation, empowering manufacturers to deliver cutting-edge devices to consumers worldwide.
