MPG tested the Apple 16.2" MacBook Pro with M2 Max Chip Z1740017Z, maxed-out excepting 4TB SSD.
About
This test uses the mt stress command of diglloydTools MemoryTester to evaluate memory bandwidth with a real application using all CPU cores.
Not to be confused with memory or CPU specifications—this is the real deal, whatever memory bandwidth an application actually has available to it, in a real operating system.
Memory bandwidth is especially important for more CPU cores or very fast CPU cores; it is important that it be proportional to the CPU computing power. Hence the 2019 Mac Pro with its 28 CPU cores needs high memory bandwidth (many cores), as does the Apple M1 Max chip (very high speed cores).

Results
The 2022 MacBook Pro M2 Max memory bandwidth is incredible, leaving the six-channel memory of the 2019 Mac Pro well behind, and the iMacs in the dust. However, its bandwidth is identical to the M1 Max chip—no change.
