A flawed review, in many ways:
1. The competing CPUs (Threadripper 5975WX) are last gen. A Threadripper 7980x would be the closest CPU to compare to, as the PRO variants are in a different league. Who would do professional work on 512GB of RAM without ECC?
2. Speaking of "epic performance", yeah, why not add the Threadripper 7995WX PRO too to the comparison?
3. The comparison is also flawed because it is comparing GPU accelerated workloads (like Handbrake) on the M3 Ultra with CPU only benchmarks on the previous gen CPUs.
4. Entire comparisons have been made between Macs only, like the File Transfer test, which shows a very weak 2.7GBs / result, which is weak even by PCIE gen 4 standards. A professional workstation can easily get over 20GB/s
5. The competing GPUs were not disclosed so it can be assumed they were not used. That shows bad faith, because a middle range current gen NVIDIA GPU can easily walk over M3Ultra, not to mention the very large professional oriented Quadros.
6. Weak selection of benchmark which have little resemblance to real world apps.
