ARM announces Cortex-A75, Cortex-A55 and Mali-G72

This time, ARM is offering vendors with a single, mixed-up cluster composed of both big and little clusters, up to a maximum of eight. The combination of flexible CPU clusters, GPU compute technology, dedicated accelerators, and the new ARM Compute Library work together to efficiently enhance and scale AI performance. Alongside those first DynamIQ microarchitecture processors ARM launched another important design today at Computex, the Mali-G72 GPU. Whereas, the Cortex-A55 chipset is 15 percent more power efficient and twice more memory efficient than the predecessor Cortex-A53.

Both new CPU are the first from ARM to be based on the new DynamIQ technology. So with the Dynamiq technology, the developers can now customise a single cluster into pairs of 4 plus 4, 1 plus 7, 2 plus 6, 1 plus 3 and many more variations. ARM has paid a lot of attention to ensuring that these new performance gains don't come at the expense of energy efficiency either.

It's another year, and another generation of ARM Cortex processors are being launched to power the newer generation of smartphones and mobile devices. The Cortex-A75 will be aimed at the premium segment while the Cortex-A55 core will cater to the mid-range category. Yes, that means VR, AR, and high-fidelity games, the latter of which ARM's research has shown have been rapidly increasing in popularity. It adds that the new processor can offer laptop-level performance while using the same amount of power as existing mobile processors.

ARM said the new A75 will find application in high-end computing environments such as autonomous cars, mega infrastructure projects and such, not to mention high-end PC and mobile devices. This English company, now owned by Japan's SoftBank, is responsible for designing the processor architecture of practically every mobile device - you'll have heard of Qualcomm's Snapdragon, Samsung's Exynos, and Apple's A-series of mobile chips, all of which are built using ARM's instruction sets and based on ARM's design blueprints. Not only this, ARM says that it is even 17 percent more efficient and better when it comes to various machine-learning processes.

Interestingly, ARM won't just be powering machine learning with its new chips, it'll benefit from ML too.

Similarly, the G72 offers 20 percent better performance density, meaning that manufacturers can pack more GPU cores into the same die area as before, giving further potential for a performance boost without an increase in cost.

To enable early adopters of ARM's new CPU IP to achieve excellent PPA results, Synopsys and ARM collaborated to develop QuickStart Implementation Kits (QIKs) for the high-performance Cortex-A75 and the high-efficiency Cortex-A55, which include the DynamIQ Shared Unit (DSU), to enable a new single-cluster design with new capabilities and more flexibility for multi-core processing.

The Mali-G72 improves energy efficiency by up to 25 percent as compared to Mali-G71.

All the new CPU designs are expected to hit devices in the first quarter of 2018.
