The press release claims that the Cortex chip delivers twice the performance of its predecessor. The Cortex-R7 was released in 2011 so twice the performance over five years is not that impressive, but better than a poke in the eye with a short stick.

The company is targeting the CPU for 5G and LTE modems, as well as next-gen storage devices.

The ARM Cortex-R8 is a quad-core with low-latency memory which can manage 2MB per core. This should make mobile downloading and data transfers faster.

Four cores have superscalar out-of-order execution capabilities to allow code being crunched by the cores to react to interrupts deterministically.

The Cortex-R8 works with existing software which makes it easy for developers to integrate it into single CPU real-time processing products and reduce design cycles.

More than 1.4 billion Cortex-R processors have found their way into data storage devices and on system-on-chip (SoC) hardware used by major hard disk drive and solid state drive makers.
ARM that a few chipmakers have already started using the chip in their SoC.
