Earlier, ARM processors came with the bigLITTLE technology which divided the CPU cores into two power clusters to distribute tasks more efficiently. Prior to ARM’s DynamIQ design, Qualcomm and others could adopt big.LITTLE designs that paired a cluster of high-performing CPUs with the same number of lower performing CPUs.
ARM is unveiling its first Dynamiq processor designs today, and the company said that the family will boost artificial intelligence performance by more than 50 times over the next three to five years.
Ahead of Intel’s Computex 2017 conference being organized in Taiwan, SoftBank-owned ARM has today taken the wraps off its first set of Dynamiq mobile processors – Cortex-A75 and Cortex-A55. For example, the developers can now embed one Cortex-A75 core and seven Cortex-A55 cores in a single cluster to save the cost and most importantly to increase the overall performance of the SoC. While nothing is yet confirmed, it has been rumored that Qualcomm’s unreleased Snapdragon 845 will use Cortex-A75 cores.
ARM says the first mobile devices to feature its new designs will likely arrive in the first quarter of 2018, though it admits some Chinese manufacturers could use them in their products before the end of this year. There’s a new GPU announced as well, the brand new Mali-G72 succeeding the G71 core announced previous year. ARM’s partners have been playing with the new designs since the end of past year. Single-threaded performance, according to ARM’s Ronco, is up by 20 percent, purely by improving the instructions-per-clock efficiency. The flexibility is granular enough to allow each core to run with different specs and speeds, and improving things on the whole, all eight cores will be put in the same cluster, allowing cache to be shared between different cores. The cores can be tweaked into pairs of 4 plus 4, 2 plus 6, 1 plus 7, 1 plus 3, and so on.
Along with the Cortex A75 and A-55 CPUs, ARM is launching a new Mali GPU based on the Bifrost architecture and designated G72. Whereas, the Cortex-A55 chipset is 15 percent more power efficient and twice more memory efficient than the predecessor Cortex-A53. It offers 16 percent more memory throughput as well. The products are enhanced by a secure foundation for billions of devices – ARM TrustZone technology – to fortify the SoC in edge devices.
It offers 1.4x rise in performance compared to the Mali-G71 GPU, 25% better energy efficiency, 17 percent higher machine learning efficiency and most importantly, 40% more performance on mobile devices. There will also be a new GPU, the Mali-G72.
ARM (Advanced RISC Machines) builds processors which are used in numerous day-to-day devices. The A75 boasts of at least 20% better performance than the A73, and now these new cores are optimized for better handling of AI and machine learning processes. These processors are the exact platform on which companies are now developing the abilities to boost mobile AI, mobile VR, and machine-learning tasks.
