ARM announced the new Cortex and a graphics accelerator Mali-G72



In late March, the company ARM announced a new architecture for creating ARM processors called DynamIQ. It is the next step after big.LITTLE and allows the system to use as many cores as it needs to perform a specific task. Now, ARM introduced the new Cortex-A75 and Cortex-A55 compatible with the architecture of DynamIQ. This means that CPU manufacturers will be able to use any combination of clusters, whether 4+4, 2+6, 1+7, 1+3 or any other. In addition, ARM has introduced a new graphics processor Mali-G72, which is an improved version of the Mali-G71, which is already used in Exynos and Kirin 960 8895.

ARM

Cortex-A75 replaced the Cortex-A73 and have a 20% performance increase in some scenarios. In addition, they have the same levels of ongoing performance and A73. This means that the performance should not decrease when performing difficult tasks over a longer period of time.

ARM

ARM pays great attention to ensuring that the new performance indicators was not achieved at the expense of increasing power consumption. ARM focuses on how to improve performance without changing the level of energy efficiency.

ARM

In some cases Cortex-A55 was recorded a greater increase in performance. For example, memory performance in some cases increased two times compared to Cortex-A53. In most cases the increase in power, as in the case of Cortex-A75 is 20%.

ARM

Cortex-A55 also has a 15% improved energy efficiency compared to Cortex-A53. On assurances of ARM chip manufacturers can choose from more than 3,000 different configurations, ranging from extra L2 and L3 caches, encryption, support for NEON and ending with eight cores per cluster.

ARM

New Cortex-Cortex A75 and A55 based on the latest ARMv8 architecture.2-A, which means that they can not be paired with existing solutions based on ARMv8-A, such as Cortex-A73 or Cortex-A53.

ARM

Among the changes ARMv8.2-A is to provide an improved memory model, data processing, floating point with half precision and support RAS (reliability, availability and serviceability) and SPE (statistical profiles extension).

ARM

Mali-G72 has not so many changes compared to the Mali-G71, as in the case of new cores and architecture DynamIQ. New graphics accelerator, got 25% improved energy efficiency and 20% increase in performance. In addition, Mali-G71 company ARM focused on 16-20 cores as the optimal solution for mobile devices, and the Mali-G72 the maximum number can reach 32.

ARM

The first solutions based on Cortex-A75, Cortex-A55 and Mali-G72 expected in the fourth quarter this year or first quarter of next.
