ARM announces Cortex-A77 and Mali-G77 for premium smartphones in 2020

ARM, the creator of blueprints and instruction set designer for all the mobile chips we enjoy using in our smartphones today, has unveiled its latest set of premium mobile designs, whose function is programmed for 2020 devices . This includes two main components: the Cortex-A77 CPU core and the Mali-G77 graphics part.

The immediate highlight with the A77 is a 20 percent improvement in the performance of the IPC (instructions per clock), which should translate into a tangible acceleration in completing complex tasks. Most system designs on a chip, such as Qualcomm, Apple and Samsung, operate with two or four robust cores like the Cortex-A77 and then a handful of more energy-efficient cores along with them for basic tasks. Since each A77 core is much more powerful than its predecessor, ARM offers more design flexibility, and we could see more high-performance chips with only two "power" cores inside them, leaving space to improve the other components of a SOC which now includes custom artificial intelligence and photo processing hardware.

ARM is not shy about presuming that the Cortex-A77 has a "performance comparable to that of current laptops," and will expect more companies to adopt it to expand the Windows offering in ARM options for laptops and laptops.

Slide: ARM

As for the new Mali-G77 GPU, there is a new architecture called Valhall (it reads like a typo, but apparently it is not), which comes with a 40 percent performance improvement . It is said that the increases in energy efficiency of microarchitecture improvements represent an increase of 30 percent, and there is a yield density 30 percent better, which allows chip designers to accumulate more power in less space. Almost as a late occurrence, the G77 chip adds 60 percent to machine learning performance, "which significantly increases the inference performance and neural network (NN) for advanced intelligence in the device."

Taken as a whole, this ARM announcement is about maintaining its performance and leadership. There is a lot in the company to facilitate the adoption of 5G, Internet of Things, AI and autonomous driving technology, but everything has to be powered by the fastest and most efficient chips, and that last part is what ARM is developing.

We can expect smart phones, tablets and the occasional laptop that will present the new Cortex-A77 and Mali-G77 designs next year. Although one of the interesting questions will be whether Huawei will be back in the good books of ARM as a licensee, or if it will remain frozen as it is now.
