What hardware architecture does the Cortex-A76 core architecture belong to?

Currently, only the RK3588 and RK3588S usethe large core architecture of Cortex-A76. The large core is the main performance growth driver of the board. The A76 is a relatively new ARMv8.2-Ahardware architecture, adopting an 8nm processor manufacturing process. The editor of Dingchang believes that the 4 A76 large cores of the RK3588 bring aqualitative improvement to 3D game performance.

The paper specification parameters of the processors of RK3588 and RK3588S are: octa-core 64-bit (4×Cortex-A76 +4×Cortex-A55), 8nm advanced process, with a maximum main frequency of 2.4GHz.

In addition, the RK3588 sometimes cannot run at the maximum main frequency of 2.4GHz, which may be due to a conservative frequency setting strategy or heat dissipation issues. The PMU limit temperature of the power management chip RK806 on the RK3588 motherboard is set at 160 degrees. It is estimated that this temperature will not be reached during normal project operation unless there is a bug or hardware failure.Generally, when the temperature exceeds 85 degrees, the frequency will be reduced.
