ARM recently announced the Cortex-A75 and Cortex-A55 processor cores, the first to support its DynamIQ technology.
ARM first revealed DynamIQ earlier this year, an advancement of its big.LITTLE technology that allows paired sets of high-power and low-power processor cores to tackle specific tasks based on the computing requirements at hand. Most significantly, DynamIQ doesn’t require evenly matched pairs; instead, it can handle one high-power processor with seven low-power processors and other combinations to give device makers more granular control over how the cores handle computing operations.
ARM claims the Cortex-A75 core improves multicore performance by 50%, providing enough processor power for laptops and even servers, while only requiring the energy from a smartphone. Compared to the A73, the A75 can handle 20% more calculations at clock speeds up to 3.0 GHz and deliver 15% more memory throughput. The A75 is meant for high-intensity use cases, such as 3D gaming and virtual reality.
The Cortex-A55 targets a wide range of computing tasks. ARM says the A55 is ten times more scalable than the A53, meaning it can ramp up from ultra low-intensity tasks to super high-intensity tasks. It’s also 15% more power efficient and twice as good as handling memory. The company says together, these advancements make the A55 two and a half times more efficient than the A53 when measuring performance-per-milliwatt. This will be a boon for mid-range smartphones.
ARM also debuted the new Mali-G72 GPU, which targets virtual reality, gaming, and machine learning on high-end devices. It delivers a 40% improvement in performance when compared to the previous generation GPU. ARM sees the A75, A55, and Mali-G72 complimenting one another in multi-core designs, such as those created by Qualcomm (Snapdragon) or Samsung (Exynos).
ARM has made these components available to companies that design processors. It’s not clear when the A75 and A55 will be built into future processor designs.
