Maybe even better..on pure power for couple a seconds, maybe minutes my former Razer laptop with mobile 3080 from around 81k in benchmark settle down to around 56kI believe it'll be as good as 3080 unless you are doing pure compute.
If this Mbp with their unified , power efficient SoC along side with a proper cooling system...they can perform over 60k all the time
Again , maybe Apple did that chart to show the performance under load for a longer period of time...no wonder the 3080 from MSI that can show the full potential is better with proper cooling system and the razer didnt
