Yesterday ARM company, absorbed by Japanese company SoftBank from autumn of last year, presented two new computing cores (Cortex-A75 and Cortex-A55) and one graphics core (Mali G72). A distinctive feature of the new products was the support of technology DynamIQ and a new set of instructions ARMv 8.2. DynamIQ technology was introduced in March .
Let's remind, DynamIQ became evolutionary development of technology big.LITTLE. So, if big.LITTLE allowed to create bundles of two clusters with different cores (up to 4 cores in each cluster), DynamIQ makes it possible to create one cluster of eight different cores, where each of them can have its own power level and its own Clock speed, as well as perform their tasks. Such an approach will allow creating highly optimized solutions. There have also been changes in the architecture of the
cache. Now each core has an individual L1 and L2 cache, and they all have access to the shared L3 cache. Previous ARM kernels carried L1 cache and shared L2.
As for the extended set of instructions, most of them are sharpened for processing tasks that can be attributed to the work of artificial intelligence. According to the developers, in due course AI should appear in "every iron", and not work somewhere in the cloud. This is the only way to ensure the daily accessibility of the masses to useful and even irreplaceable functions. In general, according to the calculations of the current owner of ARM company - SoftBank, by 2035 the ARM
cores will be exclusively in all things with an Internet connection.
The new high-performance cores Cortex-A75 introduced yesterday are oriented to the whole range of tasks. There is no more breakdown for mobile and server cores. A new development will appear in both smartphones and servers. In comparison with the Cortex-A73 cores, the performance of a single stream on the Cortex-A75 cores has grown to 20% (mobile processors). When compared with the server cores Cortex-A72, the performance of a single thread increased to 40%. All this for a single
technical process and for an equal clock frequency.
The performance of processing a single stream on the Cortex-A55 cores has increased in comparison with the Cortex-A53 cores and even more - almost twice. At the same time, the consumption of new kernels decreased by 15%. Thanks to DynamIQ technology, it was possible to assemble 8 Cortex-A55 cores in one cluster, which would simply "tear" the middle segment, which was previously dominated by a bundle of 4 Cortex-A53 cores.
According to the graphical kernels Mali G72, information is not enough. It is assumed that they are only slightly modified core of Mali G71. Related Products :
