New ARM Processors Promise 50x AI Performance Boost


ARM has recently unveiled two new processors, Cortex-A55 and Cortex-A75, based on its DynamIQ technology. With these, the company aims to boost its chips’ AI performance by 50x over the next 3-5 years. ARM also announced a new GPU, the Mali-G72, which is the successor to the G71 and claims 40% better graphic performance.

The Cortex-A75 is best suited for large-screen devices, laptops, networking equipment, and cars. In contrast, the Cortex-A55 doubles power efficiency and claims up to 2.5 times more efficiency compared to the A-53. It is optimised for tablets, smartphones, and Internet of Things (IoT) devices.

The Cortex-A75 CPU is designed to replace the A73 and the Cortex-A55 will replace the A53.

ARM’s Big.LITTLE technology is a heterogeneous processing architecture which uses two types of processor. ”LITTLE” processors are designed for maximum power efficiency while ”big” processors are designed to provide maximum compute performance.


The Cortex-A75 features four high-power cores (Big) and four low-power cores (Little), while the Cortex-A55 has one high-performance core (Big) and seven low-power cores (Little).

“DynamIQ big.LITTLE provides more multicore flexibility across more tiers of performance and user experiences by enabling configuration of big and LITTLE processors on a single compute cluster for the first time,” said ARM spokesperson in the announcement.

In addition to Cortex-A75 and Cortex-A55, ARM is launching a new Mali-G72 graphics chip (GPU) based on the Bitfrost architecture. It is optimised for VR, mobile gaming, and machine learning on high-end mobile devices. It claims 40% better graphic performance than the G71.

The devices featuring the new processors are expected to ship by 2018. For further information, click here.
