It's worth noting that this is the older version of Geekbench 5 and not the latest version of Geekbench 6, so there may be some differences in scores when tested on the latest version.

Online scores reveal that Mac Studio equipped with M2 Ultra's 24 cores delivers remarkably impressive single-core and multi-core performance. M2 Ultra outperforms its predecessor, M1 Ultra, by 18% and surpasses Intel Core i9-13900K and AMD Ryzen 7950X CPUs.

Remember, between M1 Ultra and M2 Ultra, there has been no change in the manufacturing process, as the company continues to utilize TSMC's 5nm process and still manages to enhance multi-core performance. It's somewhat puzzling that Geekbench 6 wasn't used to evaluate the 24-core M2 Ultra, but Vadim Yuryev employed calculations to provide Geekbench 6 results for M2 Ultra.

According to a YouTuber, since the Geekbench 6 score for M1 Ultra is known to be 17551, he claims that M2 Ultra will achieve a score of 20710 in the same test.
Mac Studio tested with M2 Ultra processor features 192GB of RAM, but it's uncertain whether the large memory capacity will significantly impact multi-core scores. Another noteworthy point is the chipset's highest clock speed reaching 3.68GHz, while on M1 Ultra it's 3.22GHz, and it only has a maximum of 20 cores.
