Last week, details arose about the new processors and graphics chip of ARM that will equip future smartphones to be launched in 2018. Among the novelties, we saw the Cortex-A75, focused on high performance, and the Cortex-A55, designed to offer low consumption. In the graphics section, we will see the Mali-G72 GPU with greater power for virtual reality.
Taking advantage of Computex 2017 that happens this week, ARM officialized its new chips, practically confirming everything that we saw the previous week. The big news, however, is by offering a more flexible architecture compared to what was seen with Cortex-A73 and A53 currently available on chipsets.
What we see today is a combination of four powerful cores with four low-power cores or eight A53 chipsets. Of course, there are some hex or even deca-core variations, but what the new ARM processors have to offer is the amount of each type within a single SoC.
Calling the big.LITTLE DynamIQ framework, you can create chipsets that use a single in conjunction with seven Cortex-A55s, offering low power consumption but delivering greater performance in heavier apps. This would be the ideal solution for premium intermediary smartphones.
The A75 will be fully focused on high performance, delivering a 22% gain in gross power compared to the A73. In benchmarks such as GeekBench and Google Octane, we can expect a gain of 34% and 48%, respectively. This processor is able to reach 3 GHz speed, but in smartphones, due to the limitation in heat dissipation, we can see a lower speed.
The A55, in turn, will focus on low consumption, promising a 15% reduction in energy expenditure thanks to the most advanced lithography at 10nm. For chipsets that will only use this type of processor, we can expect an 18% gain in performance compared to a current octa-core solution with Cortex-A53.
Finally, we have Mali-G72 GPU with 20% performance gain compared to the G71 in Exynos 8895 and Kirin 960. This GPU will have more power to handle graphics in applications and games in virtual reality. And just like the processors presented, it will be present in the main releases of 2018.
