Cortex-A77 & Mali-G77: New ARM CPU and GPU for Smartphones from 2020

Cortex-A77 & Mali-G77: Neue ARM-CPU und -GPU für die Smartphones von 2020

ARM has unveiled a new CPU and a new GPU model for the upcoming mobile SoCs, which should give smartphones a huge leap in performance next year. If the CPU increases by 20 percent on average, the GPU should even be 40 percent.

The new 7nm Cortex-A77 CPU is expected to provide 20 percent more power per clock (IPC) than the Cortex-A76 used in Qualcomm's Snapdragon 855, for example. The memory bandwidth is expected to increase by around 15 percent. Over the last two CPU generations, the performance in machine learning has also increased by a factor of 35. ARM also relies on the big.Little principle for the Cortex-A77, where the slower cores are replaced by slower CPU cores for background processes. In the case of the Cortex-A77, these are Cortex-A75 CPU cores. As a basic architecture, the Cortex-A77, like the Cortex-A76, relies on the ARMv8.2 architecture, which supports both AArch32 and AArch64.

GPU: 40% more power, 30% more energy efficient

On the other hand, ARM has introduced the Mali G77 GPU, which is using ARM's new Valhall architecture for the first time. Compared to the current Mali G76 GPU, the performance is expected to increase by about 40 percent, while the energy efficiency should have been improved by 30 percent. In the field of machine learning, the new GPU is even expected to grow by 60 percent.

Use in smartphones probably only in 2020

It will take until the year 2020 until the new CPU and GPU units are installed in the first smartphones. Because the respective predecessors find only now in the form of the Qualcomm Snapdragon 855 and Samsung Exynos 9820 their way into current smartphones such as the Samsung Galaxy S10 (test), the Huawei P30 Pro (test) and the OnePlus 7 Pro (test).
