I don't think the 4x Cortex-A76 + 4x Cortex-A55 is in the same league as the Apple M1, but still quite a bit faster than the Pi4's 4x Cortex-A72. IMO the node used is more important than the core design. Rockchip claims they will be using an 8nm node for the rk3588. And I think the rk3399 and Pi4 are using 28nm nodes right now. So if this chip materializes it could be much faster (compared to Linux oriented ARM boards of today).
